Features and Benefits

Factory Packaged – What You Need – When You Need It

The Trane blower coil air handler, models BCHD, BCVD, and BCCD, accommodate a variety of applications while providing a low-cost method of air conditioning and/or heating buildings. These compact, low-profile units can fit in small spaces and are floor or ceiling mounted. With a minimum of effort, they can be relocated within the building as needs change.

Blower coils are light-duty air handlers, ranging from 1.0 to 7.5 tons nominal capacity. They are typically used in schools, hospitals, offices, stores, and similar applications. Trane blower coils are UL listed to U.S. and Canadian safety standards for all:

• 115, 208, 230, 277, and 460 volt 60 hertz motors

• 220, 240, 380, and 415 volt 50 hertz motors

Single Source Responsibility

Trane is the single source of responsibility because we ship blower coils from the factory as a total package. Included in the package are factory-mounted coils, filters, controls, direct-drive motors, and duct collars. Also, factory-provided piping packages are an available option. Because we provide the total package, this helps reduce job site labor and installation time.

Figure 3. Horizontal blower coil

10 BCX-PRC001E-EN


Piping Packages

All blower coil air handlers are available with factory-built piping package options for field installation using field-supplied interconnecting piping. Basic or deluxe piping package options are available with a variety of control valve options:

• Two- or three-way

• 1/2-in, 3/4-in, 1-in, or 1 1/4-in

• Two-position or modulating

The basic piping package consists of two shut-off ball valves. The deluxe piping package has one shut-off ball valve, a strainer, and a circuit setter balancing valve. Basic or deluxe piping packages with a three-way control valve also include a balancing fitting on the bypass line.

Energy Efficiency

Trane’s commitment to providing premium quality products has led to the exclusive use of Electronically Commutated Motors (ECM) in all blower coil models. These brushless DC motors incorporate the latest technology for optimized energy efficiency, acoustical abatement, maintenance free and extended motor life. Each motor comes with a VelociTach™ motor control board that allows for programmability, soft ramp-up, better airflow control, and serial communication. Trane units equipped with ECMs are significantly more efficient than permanent split capacitor (PSC) motors or belt-drive motors and enable single-zone VAV control.

Single-zone VAV control varies the fan speed as the zone cooling or heating load changes, and can result in lower operating costs and improved occupant comfort compared to constant-speed units.

Controls

Trane offers a broad array of control options, from a simple control interface (CSTI) to the Tracer® controllers.

CSTI

The control interface is intended to be used with a field-supplied, low-voltage thermostat or controller. The control box contains a disconnect switch (optional for units with electric heat). All end devices are wired to a low-voltage terminal block and are run-tested, so only a power connection and thermostat connection is needed to commission the unit. Changeover sensors and controls are provided whenever a change-over coil is selected.

Tracer® Controllers

The Tracer® family of controllers, ZN010, ZN510, ZN520, and UC400-B offers the combined advantages of simple and dependable operation with the latest Trane-designed controller. Standard control features include options normally available on more elaborate control systems. All control options are available factory-configured or can be field-configured using Rover service software for the ZN controllers, the UC400-B is serviced via Tracer® TU.

This is the industry’s first solution that is factory-mounted, wired, and programmed for infinite modulation of fan speed based on space loads, using the Tracer® UC400-B.

End Devices

Optional factory-mounted end devices such as a condensate float switch, freezestat, control valves, and actuators are available. Factory-installed and -wired electric heat features single-point power connection.

BCX-PRC001E-EN 11


Flexibility

The Trane blower coil is available in either horizontal (model BCHD), vertical (model BCVD), or compact vertical (model BCCD) configurations. Horizontal units are typically ceiling suspended via threaded rods. Knockouts are provided in all four corners to pass the rods through the unit. Horizontal units can also be floor mounted. Vertical units are typically floor mounted. They have a side inlet for easy duct connection, and do not require a field-fabricated inlet plenum. Vertical units ship in two pieces and can be set up in either a pre-swirl or counter-swirl configuration. Compact vertical units are floor mounted and ship in one piece.

In addition, blower coils have acoustical benefits because they are typically located outside the occupied space, either in the ceiling or in a closet. This limits the amount of sound transmission (radiated) directly from the unit to the occupant. These units are applied with discharge ductwork, which is frequently lined to help reduce the sound transmission (discharge) through the ductwork into the occupied space. Blower coils utilize a direct-drive motor solution for all units which eliminates the single phase motor hum which is evident in capacitor split motors in belt-drive applications.

Coil Options

Trane blower coils feature a wide variety of coil options that include:

• Two-, four-, or six-row hydronic cooling or heating

• Three-, four-, or six-row DX coils

• High capacity hydronic coils for cooling or heating

• One- or two-row heating coil in either the preheat or reheat position

• One-row steam preheat

Filter Placement Options

All hydronic units have an internal flat filter frame for 1- or 2-inch filters. Other filter placement options include:

• Angle filter box for 2-inch filters

• Combination angle filter/mixing box

• Bottom or top access filter box that accommodates 2-inch filters. This option allows easy filter access through a hinged door, from the bottom of the unit on horizontal units, and from the top on vertical units.

Motor Options

Direct-drive motors range from 1/2 to 3 horsepower in a wide range of voltages. All motors have internal current overload protection, permanently sealed ball bearings, and rubber grommets on the mounting brackets to reduce noise and vibration transmission.

Motors come factory programmed for specific job requirements or can be programed based on standardized motor speeds. Motors speeds have the ability to be adjusted on the job site with out the requirement of specialized tools. This enables the unit to be balanced for changes to design static pressures fast and easy.

12 BCX-PRC001E-EN


Indoor Air Quality

Indoor air quality is becoming a greater concern every day. That’s why Trane provides the most complete indoor air quality options of any manufacturer.

Drain Pans

Filtration

All units have an internal flat filter frame that can accommodate 1- or 2-inch filters. An optional bottom (horizontal units) or top (vertical units) filter access box is also available to improve accessibility.

An optional angle filter box (2-inch only), or combination angle filter/mixing box, provides extra filter face area, which results in extremely low face velocities and low pressure drop. With increased face area, the angle filters have substantially more dust-holding capacity than conventional flat filters. MERV 8 and MERV 13 pleated angle or flat filters options are available.

Ventilation

The optional mixing box delivers ventilation air directly to each unit. When the unit is equipped with a Tracer® ZN520 or UC400-B controller, the mixing box functions as a zero to 100 percent economizer to improve energy efficiency. For units configured to automatically switch between high and low fan speeds, the Tracer® ZN520 or UC400-B controller automatically adjusts the mixing box damper to provide the correct amount of fresh air to the space at all fan speeds.

Blower coil units are draw-thru configurations that use direct-drive fan motors with higher horsepower than fan coils. This makes them an excellent choice for use in an air supply ductwork system with diffusers—rather than a direct discharge system—because it enhances the space air mixing and ventilation effectiveness.

Dehumidification

For direct control of space humidity, a blower coil can be configured with a hydronic heating coil in the reheat position and equipped with a Tracer® ZN520 or UC400-B controller. These controllers can independently modulate the cooling and heating coils to directly control both temperature and humidity in the space.

Figure 4. Drain pan

The Trane blower coil uses a polymer or optional stainless steel drain pan, sloped in both directions to drain properly. The drain pans are easily removable and cleanable. Also, the main and auxiliary connections are on the same side. Compact vertical units include an internal trap.

Accessibility and Cleanability

Trane blower coils have 1-inch dual density insulation that meets NFPA90A and UL181, which is designed to withstand high velocities. Trane optionally offers 1-inch foil faced insulation that meets NFPA90A, UL181, and bacteriological standard ASTM C 665.

Coils mount above—not in—the drain pan and are not a structural part of the unit. The coils are easily removable and slide in and out on rails for cleaning. The drain pan is also easily removable for cleaning.

BCX-PRC001E-EN 13


Easy to Service

The coils and motor are easily replaced within minutes, even when the unit is suspended. Coils slide in and out by removing the coil access panel and a few screws at the rear of the unit. With the bottom filter access option, filters are easily accessed from the bottom of the unit. If the motor requires servicing, only the motor side requires access.

Durability

Trane blower coils use durable materials, including heavy gage, galvanized steel for the casing.

Optional Accessory Sections

These accessory sections make the BCHD/BCVD product more flexible:

• Mixing box

• Angle filter box

• Angle filter and mixing box section

• Bottom or top hinged access filter box

• Electric heat box

• Steam coil box

Mixing Box

Angle Filter or Angle Filter/Mixing Box Combination

Figure 5. Mixing box

The mixing box option ships separately and has internal low-leak aluminum dampers and access panels on both sides. The mixing box is insulated in the same as the main unit: matte or foil, as ordered. The mixing box is easily located in field to allow “back/bottom” dampers.

Figure 6. Angle filter/mixing box combo

Filter box options include an angle filter box and a bottom/top access filter box that are factory-installed. The angle filter can be combined with the mixing box as one accessory module. The flat filter frame can accommodate 1- or 2-inch filters. The angle filter frame accommodates only 2-inch filters.

Electric Heat

A factory installed open-wire electric heater is available in a wide variety of voltages and kW’s. All units have a single point power connection. Optional heater fuses, magnetic contactors, and a heater door interlocking disconnect switch are available.

Steam Coils

Application Considerations

Single-Zone, Constant Volume Applications

The Trane blower coil air handler offers a wide range of application flexibility between the fan coil unit and Climate Changer™ air handlers. Units are available in seven nominal capacities ranging from 1.0 to 7.5 tons cooling and 400 to 3000 cfm airflow. The basic unit is available in horizontal (model BCHD), vertical (model BCVD), and compact vertical (model BCCD) configurations.

The single-zone, constant volume applications discussed in this section are:

• Two-pipe hydronic units

• Two-pipe hydronic units with electric heat

• Four-pipe hydronic units

• Economizer

Other applications are:

• DX cooling

• Two-pipe hydronic units with steam heating

• Single-zone VAV

Two-Pipe Hydronic Units

The standard blower coil is equipped with a hydronic coil. The unit can perform cooling only, heating and cooling (changeover system), or heating only. In a changeover system, the unit cools during the spring, summer, and fall seasons (summer mode) and heats during the winter season (winter mode).

Use the Trane Official Product Selection System (TOPSS™) program for specific design criteria such as flow rate, temperature rise/drop, pressure drop, glycol mixtures, and capacity.

When selecting two-pipe changeover units, note that TOPSS will only provide output that meets both the cooling and heating capacity requirements. Because cooling and heating capacity requirements for a given unit may differ significantly, a given coil may be optimally sized for one load and over/under sized for the other load.

Two-Pipe Hydronic Units With Electric Heat

With the addition of electric heat, the two-pipe system can heat or cool. In the non-changeover system, the main coil is always used for cooling and the electric heater is always used for heating. In the changeover system, during the summer mode (spring, summer and fall), the main coil is used for cooling and electric heater is used for heating. During the winter mode, the main coil is used for heating and the electric heater is disabled.

Two-pipe systems with electric heat are an economical solution to intermediate season (spring and fall) comfort problems associated with straight two-pipe systems. In moderate climates or where electric rates are low, non-changeover systems are typically used. In climates with significant heating loads and/or high electric rates, a changeover system—to allow hydronic heating—is typically used.

All units with factory mounted electric heat are UL listed and interlocked with the fan motor switch. A call for Electric heat operation will turn the fan on. Motors controls are synchronized with fan/valve operation to ensure safe operation and that two modes of heat are not operating simultaneously. A transformer is supplied on any voltage unit, eliminating the need for field installation of a step-down transformer. Units come with either contactors or relays on the electric heat. A high temperature cutout with automatic reset is provided as an integral part of the elements to de-energize the electric heat in the event of a malfunction.

16 BCX-PRC001E-EN


Changeover in Two-Pipe Systems

Changing between cooling and heating modes in a two-pipe system requires energy to heat or cool the mass of water in the piping system at switchover. ASHRAE Standard 90.1–2001 defines specific requirements for minimizing the energy impact of this switchover:

• The system must allow a deadband between changeover from one mode to the other of at least 15°F outdoor-air temperature.

• The system must include controls that allow the system to operate in one mode for at least four hours before changing to the other mode.

• Reset controls must be provided to allow heating and cooling supply-water temperatures, at the changeover point, to be no more than 30°F apart.

Four-Pipe Hydronic Units

The addition of a one-row or two-row heating coil to the basic blower coil makes it compatible for a four-pipe cooling and heating system. The heating coil is available factory installed in either the preheat or reheat position.

Four-pipe systems solve the intermediate season (spring and fall) comfort problems associated with straight two-pipe systems because they only either cool or heat year-round. However, they do require chiller and boiler operation to be available to operate year-round.

When making the choice between a two or four-pipe system, also consider:

• Cooling/heating loads in perimeter zones of the building

• Importance of temperature and humidity control for the zone

• First cost

TOPSS allows independent selection of the cooling and heating coils for flexibility in flow rates, pressure drops, temperature rise/drop, and fluid type.

Economizer

Adding a mixing box with a damper actuator allows economizer or free cooling applications. When using blower coils for these applications, Trane highly recommends using a freeze protection device to protect the coil(s). If the unit has a Tracer® ZN520 or UC400-B controller, you must have an outside air temperature signal from either a hard wired outside air sensor or from the building automation system, such as Tracer® Summit.

DX Cooling Units

Blower coils with a DX cooling coil will often be connected to an air-cooled condensing unit. Some condensing units have two, independent refrigeration circuits; DX coils in units sizes 12 to 60 are single-circuited. Six-row DX coils in units sizes 72 and 90 are always dual-circuited. 6-row DX coils in unit sizes 72 and 90 are always dual-circuited.

Note: Do not manifold two independent refrigeration circuits into a single-circuited DX (evaporator) coil.

Dehumidification

There are two methods for improving the dehumidification performance of the constant-volume unit with a blower coil:

• Four-pipe unit with reheat

• Chilled water reset

BCX-PRC001E-EN 17


Four-Pipe Unit with Reheat

Blower coils equipped with a Tracer® ZN520 or UC400-B controller and a hydronic heating coil in the reheat position will provide direct control of space humidity. If the space humidity level does not exceed the desired upper limit, the unit responds to reduced cooling load by modulating the control valve and, if in AUTO mode, switching between fan speeds. However, if the space humidity level rises above the upper limit, the capacity of the cooling coil is increased, overcooling the air to maintain the space humidity below the upper limit. Then, the capacity of the heating coil modulates, adding a small amount of heat to temper the air and avoid overcooling the space.

The Tracer® ZN520 or UC400-B controller responds to a signal from a humidity sensor installed in the space or a signal from a building automation system, and independently modulates the cooling and heating coils to directly control both temperature and humidity in the space. While this configuration can directly control indoor humidity levels, it does require the boiler (or other source of heat) to be available year-round.

Chilled-Water Reset

In many constant-flow pumping systems, the leaving chilled-water temperature setpoint is reset based on either outdoor dry-bulb temperature or some indication of cooling load. Use caution when implementing a chilled-water reset strategy because space humidity control can be compromised if the water gets too warm.

Blower coils equipped with a Tracer® ZN520 or UC400-B can accept an input signal from a humidity sensor in the space. A building automation system will continually poll the humidity level in all spaces, or in a single representative space, to limit the amount of chilled-water reset and maintain space humidity levels.

Location and Installation

Avoid locating the unit directly above spaces where sound levels may be critical, such as areas near the occupied space. Install horizontal units over false ceilings in service areas such as corridors or storage rooms. Install vertical units in closets or mechanical rooms.

Horizontal units are installed by suspending the corners of the unit with threaded rods. Use suitable vibration isolators and take the following precautions to comply with generally accepted installation practices.

• Use flexible duct connectors or supply and return sides (if ducted).

• Use acoustic lining on the inside of main supply duct for noise control.

• Do not attach ceiling suspension wires to unit or through ducts.

• Locate return air grilles as far as possible from the unit to avoid noise transmission.

• Design and install ductwork as per ASHRAE guides, SMACNA, and local code requirements.

Acoustics

Controlling outdoor and equipment noise within the occupied space is increasingly important to system designers and building occupants/owners. Therefore, give proper consideration to this subject in the application of the blower coil.

Selecting fan and coil combinations is inherently flexible for sound-sensitive applications. In such instances, a fan running at low speed with a high capacity coil normally yields satisfactory results. It also may be desirable to select a larger nominal capacity unit and operate it at less than nominal airflow for further acoustic benefit.

BCHD/BCVD sound power, Lw, data for ducted discharge, inlet + casing, and casing radiated components is available in Trane Official Product Selection Software (TOPSS). This sound power data is useful in estimating the sound levels in the occupied space for a given application.

18 BCX-PRC001E-EN


Operating Limitations

Reference the General Data section for minimum and maximum operating limits. Units must not operate above maximum fan rpm or unit airflow. Unit operation above the maximum fan rpm will drastically reduce bearing life and may result in catastrophic failure. Operating the unit above the maximum airflow in the cooling mode may result in unsatisfactory operation due to water carryover from the coil. In addition, it is often uneconomical to operate a unit at its maximum rpm due to greater motor power requirements.

The unit may not perform at an optimal acoustical performance level if it operates in the fan’s traditional stall region.

Do not operate units with electric heat below the minimum airflow limit to prevent excessive leaving air temperatures and electric heat limit trips.

Do not operate hydronic and electric heat simultaneously to prevent excessive leaving air temperatures and limit trips. Electric heat units have a lockout switch to disable the electric heater if the temperature off the hydronic coil is greater than 95°F.

Do not operate units with a leaving air temperature above 104°F for units with a single-phase motor. Do not operate units with a leaving air temperature above 130° F for units with a three-phase motor.

Do not operate coils above the water flow limits to prevent erosion and noise. A minimum or “self-venting” water flow rate is also listed in the General Data Section. If the coil is set to operate below this flow rate, vent it periodically by flushing at a higher flow rate.

Do not operate piping packages and water valves above the water flow limit to prevent erosion and noise. Water valves supplied with blower coils as accessories are intended for use in “treated” closed loop chilled or hot water systems.

Note: Do not use valves with open or potable water systems. Untreated water may cause scaling and particulate collection interference with the valve function, and reduce the life and effectiveness of the valve.

Selection Procedure

Selecting a Unit

These selection procedures are for manual computations using the general data and capacity tables in this catalog. For particular design conditions not in this catalog, use the Trane Official Product Selection System (TOPSS) or contact your local Trane office.

1. Determine unit capacity. Refer unit capacities on p. 59 - p. 81 to determine unit size needed for cooling and/or heating. Interpolate between given values when necessary.

2. Verify air and water flow operating limits. If design airflow equals the unit rated airflow with the chosen coil, use the waterflow rate shown in the appropriate performance table. If using interpolation to determine capacity, determine waterflow using the formula: gpm = total capacity (MBh) / [(0.5) x (water temperature rise)].

Note: Airflow and water flow must fall within the unit operating limits in general data Table 1, p. 26 and Table 2, p. 27 or you must reselect the unit.

3. Heating coils only: If entering air and water conditions are different than 60/180°F or 60/120°F respectively, refer to the associated correction factors in Table 28, p. 85. Divide the required capacity by the correction factor and then refer to the table to locate the corrected capacity.

4. Calculate the water pressure drop (hydronic coils only). Determine water pressure drop using the appropriate figure on p. 16 - p. 22.

5. Check fan performance requirements. Reference fan performance data by unit size and configuration on p. 43 - p. 59. These curves include pressure drops from the casing only. Reference air pressure drop for coils, filters, and accessories using Table 8, p. 30, Table 9, p. 31, Table 10, p. 32, and Table 11, p. 33.

6. Calculate total static pressure requirements. Add the external static pressure (ESP) of the coil, filter, and accessories to the system esp to obtain the total fan static pressure requirement. Then determine BHP and fan RPM requirements using the fan performance curves. Then determine which motor to use.

7. Determine motor size. Check motor HP and fan RPM requirements to determine the correct motor and size.

8. The fan curves use the motor hp. Check CFM and SP to determine which motor and RPM will meet the application. Select TOPSS base performance in order to use the TOPSS calculated RPM.

Selection Procedure

Cooling Selection Example

Job example:

• Horizontal blower coil

• 2-inch pleated media filters

• Mixing box with dampers

• Total capacity required: 53.0 MBh

• Sensible capacity required: 42.9 MBh

• Airflow: 2000 cfm, 0.25” ESP

• Entering air conditions: 80°F DB/67°F WB

• Entering water: 45°F

• Water temperature rise: 10°F

1. Determine unit capacity. Using Table 13, p. 60, the capacity of a BCHD 54 with a six-row coil, 10°F ΔT at 1800 cfm, is 74.51 MBh total and 52.3 MBh sensible. At 2250 cfm, it is 88.7 MBh total and 63.4 MBh sensible. Interpolate between these values for 2000 cfm to obtain 80.9 MBh total and 56.7 sensible.

2. Verify CFM and GPM limits. Using Table 13, p. 60, the water flow rate = 16.1 gpm. Reference Table 1, p. 26 and Table 10, p. 32 for airflow and water limits. Both the water flow rate (16.1 gpm) and airflow (2000 cfm) fall within the range specified for a BCHD054 with a six-row cooling coil.

3. Calculate WPD. From Table 13, p. 60, the water pressure drop for a size 54 unit, six-row coil at 16.1 gpm = 4.8 feet of water.

4. Check fan performance requirements. Calculate the air pressure drop for all components using Table 8, p. 30 and Table 10, p. 32, air pressure drop adjustment. Interpolate for 2000 cfm as follows:

5. Calculate TSP. Unit apd 1.135 inch wg + 0.25 inch wg ESP= 1.385 inch wg total static pressure.

6. Determine motor and drive size. Using Figure 41, p. 45 (fan performance), use the graph for 2000 cfm at 1.385 inches wg total static pressure to obtain 955 rpm and 1.0 HP 115/208-230V or 277V motor. Select TOPSS Base Performance to operate at 955 rpm.

Selection Procedure

Heating Selection Example

Select a heating coil for the BCHD054, selected in the cooling selection example. Operating conditions are:

• 2000 cfm

• EWT = 170°F

• EAT = 60°F

• LAT = 120°F

1. Determine unit capacity. Required capacity = CFM x 1.085 x (LAT - EAT) = 2000 x 1.085 x (120 - 60) = 130,200 Btu (130.2 MBh)

The capacity correction factor for a two-row coil is 0.917 for EAT = 60°F and EWT = 170°F. Corrected capacity required = 130.2/0.917 = 142.0 MBh

2. Verify water flow and airflow limits. Reference Table 1, p. 26 for water flow limits and Table 3, p. 28 for cfm limits. Both the water flow rate (10.9 gpm) and airflow (2000 cfm) fall within the range specified for a BCHD 054 with a 2-row heating coil.

3. Calculate water pressure drop (WPD). From Figure 27, p. 39, the water pressure drop for a size 54 unit is 20 feet of water. The wpd correction factor for the average water temperature through the coil from Table 28, p. 85 is 1.01. Corrected water pressure drop = 2.0 x 1.01 = 2.02 feet of water.

4. Calculate total static pressure and determine motor size. From Table 8, p. 30, air pressure drop for a BCHD size 54 two-row coil is 0.222 inches wg. Adding this pressure drop to the total static pressure (calculated in the cooling example) gives a total static pressure of 1.356 inches wg. From Figure 39, p. 106, use the graph for 2000 cfm and 1.446 inches wg, we obtain 975 rpm and 1.0 115/208-230V or 277V motor. Select TOPSS Base Performance to operate at 975 rpm.

Notes:

• Light shading = GPM is below the minimum (<1.5 fps self-venting velocity) or WPD is above the maximum (>10 ft wg) recommended for most applications.• Dark shading = GPM is below the AHRI limits (1.0 fps tube side velocity).• Some of the volumetric flow rates are less than those required for self-venting. For more information, refer to the BCCD coil general data table.• Capacities calculated with 0.00000 tube-side fouling factor.• High-capacity coils applicable where higher water pressure differentials are acceptable and are also recommended for EarthwiseTM applications.• EarthwiseTM is a trademark of Trane to identify equipment designed for applications requiring greater water temperature rises, lower entering water

Notes: To select the correct distributor size at conditions exactly matching those shown on this table, use the shading legend below:• No shade = 3/16 in. x 0.049 wall distributor tubes• Light shading = 3/16 in. x 0.032 wall distributor tubes.• Dark shading = Distributor load (MBh) per circuit is under the minimum for 3/16 in. x 0.049 distributor or over the maximum for 3/16 in. x 0.032 distributor.

Use only for interpolation• Values shown in this table are based on a liquid condensing temperature of 105°F. Capacities at liquid condensing temperatures between 90°F and 120°F

will generally be within ±5 percent of capacities shown in this table• Distributor selection is based on TC capacities divided by number of circuits. For more information, refer to the BCHD/BCVD - number of circuits per coil

general data table.• To select the correct distributor size at conditions other than exactly shown in this table interpolate to calculate the TC MBh, divide it by the number of

circuits For more information, refer to the BCHD/BCVD - number of circuits per coil general data and plot the result within the Performance Data section on the figure displaying the R-410A Blower coil distributor selection.

• TC and SC values do not include heat generated by the fan and motor.• TC = total capacity (MBh); SC = sensible capacity (MBh); GPM = water flow rate-gallons per minute; LDB = leaving dry-bulb temperature (°F); LWB =

Light shading = GPM is below the minimum (<1.5 fps self-venting velocity) or WPD is above the maximum (>10 ft wg) recommended for most applications.Dark shading = LAT must be less than 104°F to avoid overheating the motor on single phase.Notes:

• Capacities calculated with 0.00025 fouling factor.• Fluid flow in GPM; fluid PD in feet of water• Useful formulas:

LAT = EAT + (TC x 922.1)/CFMLWT = EWT - (TC x 2.0)/GPM

• High-capacity coils applicable where higher water pressure differentials are acceptable and are also recommended for EarthwiseTM applications (see Performance data correction factors).

• EarthwiseTM is a trademark of Trane to identify equipment designed for applications requiring greater water temperature rises, lower entering water temperatures (EWT) and lower air supply temperatures (LDB).

• TC = total capacity (MBh); SC = sensible capacity (MBh); GPM = water flow rate-gallons per minute; LDB = leaving dry-bulb temperature (°F); LWB = leaving wet-bulb temperature (°F); WPD = water pressure drop at average water density (ft H20).

Why Trane Controls?

Trane offers a broad range of control packages from a field convertible end-device package, to a complete building automation system solution with BACnet® or LonTalk® controls.

The good news is Trane controls are factory-mounted, wired, tested and configured or programmed with Trane application expertise to provide comfort, efficiency, and reliability, as well as single-source warranty and service.WithTrane integrated controls, the installed costs are lower because the equipment has turn-key factory controls and every component of the system is optimized to fit with the controller.Trane installs not only the controller, but also the hardware that works intimately with the controller to allow the system to function properly (i.e., piping package, valves, dampers, actuators, etc.). When a product with Trane controls arrives on the jobsite, it is completely ready for quick installation.

Control Options

Available control options are:

• Manual fan speed switch (FSS)

• Customer-supplied terminal interface (CSTI)

• Tracer® ZN010 controller



• Tracer® UC400-B controller with optional Air-Fi® Wireless Communications Interface (WCI)

Manual Fan Speed Switch

Customer Supplied Terminal Interface (CSTI)

The CSTI is intended to be used with a field-supplied, low-voltage thermostat or controller. The control box contains a relay board which includes a line voltage to 24-volt transformer and disconnect switch (for non-electric heat units). All end devices are wired to a low-voltage terminal block and are run-tested, so the only a power connection and thermostat connection is needed to commission the unit. Changeover sensors and controls are provided whenever a change-over coil is selected. When N.O. valves are selected, inverting relays are provided for use with standard thermostats.

Figure 72. Fan speed switch

The manual fan mode switch is available for units that do not have Trane factory-mounted control packages. This four-position switch (off, high, medium, low) allows manual fan mode selection. This wall-mounted option is low-voltage and has three 24 volt relays using a factory-wired transformer and relays to control the fan motor.

The CSTI adapter board provides all the hookups as the standard adapter board, but in addition, provides hookups for valve control (main and auxiliary coils), electric heat control, and damper control. Screw terminal blocks provide convenient access to fan controls and to end device control. In addition, a courtesy 10-Vdc supply is provided for use with an external potentiometer or rheostat. The 10-Vdc supply supports up to 10 mA draw.

Tracer® Controllers

Tracer® ZN010 controller is a stand-alone microprocessor controller. Tracer® ZN510 controller can be used as either a stand-alone or communicating microprocessor controller.

Tracer® ZN520 Controller

The Tracer® ZN520 controller is a factory-installed, -tested and -commissioned LonTalk® control designed to provide control of Trane products. Features include:

• Automatic fan-speed reset

• Automatic ventilation reset

• Active dehumidification

• Manual output test

• Filter maintenance

• Master slave

• Water valve override

• Freeze avoidance

• Interoperability

• Three generic I/O ports

The Tracer® ZN520 controller is designed to be used in the following applications:

• As part of a Tracer® SC or Tracer® Summit building automation system (BAS), the Tracer® ZN520 becomes an important part of the Tracer control system.

• The Tracer® ZN520 can function as a completely stand-alone controller in situations where a BAS is not present.

• For situations when a non-Trane BAS is present, the Tracer® ZN520 can be used as an inter-operable unit controller.

Through building management of the HVAC system, optimizing energy consumption becomes possible at the room level. Each unit is capable of functioning independently of one another during occupied and unoccupied hours of the day. This allows the temperature setpoint and ventilation setting to be changed automatically based on usage.

Two Systems in One

In a Tracer® system environment, the Tracer® ZN520 is pre-designed to install quickly and easily into the system. Since the controller and the unit are factory tested and commissioned, the start-up time for the entire system is minimized. Trane becomes the single source of responsibility for the equipment, unit controls, and building automation system.

As a standalone controller, the Tracer® ZN520 is ideally suited for fix-on-fail replacement of units with old pneumatic controllers, or in situations where a BAS will be added at a later date. Once power is applied to the controller, it will automatically start up and run based upon the setpoint on the local zone sensor. An individual time clock can be added to the unit for local scheduling.

The Tracer® ZN520 is certified to the interoperable LONMARK® Space Comfort Controller profile. This allows the controller to be used with another vendor’s BAS and thereby still provide the high quality of factory installation and testing. In addition, the Tracer® ZN520 provides one of the most extensive interoperable data lists of any controller of its type in the industry.

Tracer® UC400-B Controller

The Tracer® UC400-B single-zone VAV controller can be used in a stand-alone application or as part of a Tracer® control system.

In the stand-alone configuration, Tracer® UC400-B receives operation commands from the zone sensor and/or the auto changeover sensor (on auto changeover units).The entering water temperature is read from the auto changeover sensor and determines if the unit is capable of cooling or heating. The zone sensor module is capable of transmitting the following information to the controller:

• Timed override on/cancel request

• Zone setpoint

• Current zone temperature

• Fan mode selection (off-auto-high-med-low)

For optimal system performance, units can operate as part of a Tracer® SC building automation system. The controller is linked directly to the Tracer® SC via a twisted pair communication wire, requiring no additional interface device (i.e., a command unit). The Tracer® control system can monitor or override Tracer® UC400-B control points.This includes such points as temperature and output positions.

Tracer® Controller Features

The Tracer® family of controllers, ZN010, ZN510, ZN520, and UC400-B offer the combined advantages of simple and dependable operation with the latest Trane-designed controller. Standard control features include options normally available on more elaborate control systems. All control options are available factory-configured or can be field-configured using Rover or Tracer® TU service software. For more detailed information, refer to Trane installation manuals CNT-IOP-1 (for Tracer® ZN010 or ZN510), CNT-SVX04*-EN (for Tracer® ZN520), or BAS-SVX48-EN (for Tracer® UC400-B).

Features Available on All Controllers

The following control functions are standard features on units with Tracer® ZN010, ZN510, ZN520, or Tracer® UC400-B.

Entering Water Temperature Sampling Function

A system that uses a two-way control valve option might not sense the correct entering water temperature during long periods when the control valve is closed. If the demand for heating or cooling does not exist for a long period, the entering water will eventually approach ambient temperature.

Using the entering water temperature sampling function, the controller provides accurate two-pipe system changeover-without sacrificing the benefits of two-way control valves. Also, it eliminates inefficient bleed or bypass lines that can allow unnecessary waterflow through the system.

This function periodically samples the entering water temperature by opening the hydronic valve. The valve opens for 20 seconds to allow the water temperature to stabilize.Then the controller reads the entering water temperature for up to three minutes to see if the correct water temperature is available for the selected operating mode.

The entering water temperature must be five degrees or more above the space temperature to allow hydronic heating and five degrees or more below the space temperature to allow hydronic cooling. If the correct water temperature for the operating mode is available, the unit begins normal heating or cooling operation. If the correct water temperature is not available, the controller closes the control valve and waits 60 minutes before attempting to sample the entering water temperature again.

90 BCX-PRC001E-EN

Controls

A factory-mounted thermistor senses the entering water temperature on changeover cooling/ heating coil units. If the fan coil has a factory-mounted piping package, the sensor is strapped to the entering water pipe. If the fan coil does not have a piping package, the sensor is coiled in the end pocket for mounting on customer-supplied piping.This sensor must detect accurate water temperature for proper changeover.

Automatic Heat/Cool Mode Determination

The controller automatically determines whether heating or cooling is needed-based on space and system conditions. Using a proportional/integral (PI) control algorithm to maintain the space temperature at the active heating or cooling setpoint.The controller measures the space temperature and active setpoint temperature to determine the unit's heating or cooling capacity (zero to 100 percent).

Occupied/Unoccupied Operation

The occupancy input uses a binary switch (i.e., motion sensor, time clock, etc.) that allows the zone sensor to use its unoccupied internal setpoints.

Random Start

This feature randomly staggers multiple unit start-up to reduce electrical demand spikes.

Warm-up

The two-position fresh air damper option closes during the occupied mode when the space temperature is three degrees or more below the heating setpoint temperature.The damper remains closed during warm-up until the space temperature is within two degrees of the heating setpoint temperature.

Cool-down

The two-position fresh air damper option closes during the occupied mode when the space temperature is three degrees or more above the cooling setpoint temperature.The damper remains closed during cool-down until the space temperature is within two degrees of the cooling setpoint temperature.

Manual Output Test

This function may be initiated from the blue test push button on the controller or through the Rover or Tracer® TU service tool.This feature is used to manually exercise the outputs in a defined sequence.

The purpose of this test sequence is to verify output and end device operation.The manual output test function may also be used in the following situations:

• Reset latching diagnostics

• Verify output wiring and operation

• Force the water valve(s) open to balance the hydronic system during installation set-up or service.

BCX-PRC001E-EN 91

Controls

Peer-to-Peer Communication (Tracer® ZN510, ZN520, and UC400-B)

Peer-to-peer communication allows multiple units in one space to share the same zone sensor and provide simultaneous heating and cooling.The Tracer® ZN510 or ZN520 controller can share information between units on the same communication link using a twisted pair wire in the field. Unit configuration must be modified with Rover service tool.On the Tracer® UC400-B, zone sensor data sharing can be accomplished by use of the BAS system controller.

A thermistor to sense fresh air is factory-mounted at the unit's fresh air opening for use in economizer applications or as a read-only point for Tracer® SC or Tracer® Summit. If the fresh air temperature is a read-only value, it will not impact the control algorithm. In an economizer application, a fresh air temperature signal must be provided either by this thermistor, Tracer® SC, or Tracer® Summit.

Additional Features

When the zone temperature drops to heating setpoint, the fan continues to operate at minimum speed and the DAT setpoint is reset further upward. Heating capacity is modulated or staged to maintain this DAT setpoint. If the zone heating load increases to the point where DAT reaches the maximum limit, fan speed is again increased, while heating capacity is modulated or staged to maintain DAT at this maximum limit.

Economizing Control (Tracer® ZN520)

With the controller configured for economizing control, it will calculate the required cooling capacity every ten seconds and modulate the damper option open to the calculated position. If the setpoint is not satisfied, the damper will continue to open until the setpoint condition has been met or the damper is 100 percent open. If this still does not satisfy the setpoint, the cooling valve option will begin to open and try to satisfy the load requirements. Once capacity exceeds the load requirements, the valve will begin to close until the setpoint has been reached or the damper reaches its minimum position, which is field-adjustable.This option uses a three-wire, floating point damper actuator.

A thermistor to sense discharge air is factory mounted near the discharge surface of the last coil for use in economizing and cascade temperature control.Tracer® SC or Tracer® Summit can also use this temperature value as a read-only point. Cascade temperature control uses both the zone and discharge air temperatures to more accurately calculate the required unit capacity.

Figure 74. Single-zone VAV control

Single-zone VAV control. Single-zone VAV control aries the speed of the EC fan motor as the zone cooling or heating load changes. When the zone is at design cooling load, the unit operates the fan at maximum speed and cooling capacity is modulated or cycled to deliver the air at the design discharge air temperature (DAT) setpoint for cooling. As the zone cooling load decreases, fan speed is reduced to maintain zone temperature at cooling setpoint, while cooling capacity (and/or economizer) is modulated or cycled to maintain DAT at the same design setpoint. When the fan has reached minimum speed, and the zone cooling load continues to decrease, the fan continues to operate at minimum speed while the DAT setpoint begins to reset upward to maintain zone temperature at cooling setpoint. Cooling capacity (and/or economizer) is modulated or cycled to maintain this DAT setpoint.

Automatic Fan and Ventilation Reset

A two-speed fan control for the unit delivers the airflow output customized to support the cfm space needs.When less cfm is necessary to meet the load of the classroom (typically 75 to 80 percent of the time), the equipment operates on low speed. However, if the room temperature rises, the controller will switch to high speed, and the outside air damper will adjust to satisfy the space needs.This helps maintain the proper amount of ventilation air to the occupants independent of the fan speed. As part of the ventilation strategy, the controller will reposition the outside air damper to confirm the minimum outside air cfm is met at both operating conditions.

Filter Maintenance

Filter status for the controller is based on the cumulative run hours of the unit fan. The controller compares the amount of fan run time against an adjustable fan run hour (stored in the controller) to determine when maintenance is recommended for the unit. The run-hours value may be user edited as required (through Rover or Tracer® TU). The valid range for the fan run hours limit is 0 to 5000 hours with a default of 600 hours. Once the run hours limit has been exceeded, the controller generates a maintenance required diagnostic (unit will not shut-down). The user will be notified of this diagnostic through the building automation system or when a Trane service tool is communicating with the controller.

Active Dehumidification

On units with reheat coils, the controller can provide active dehumidification. This means that the relative humidity in the space can be kept below an adjustable setpoint independent of outdoor weather conditions. Indoor humidity levels are recommended by ASHRAE to be kept below 60 percent in order to minimize microbial growth and the life span of airborne illness causing germs.

Master Slave (Data Sharing)

The controller can send or receive data (setpoint, heat/cool mode, fan request, space temperature, etc.) to and from other controllers on the communication link with or without the existence of a building automation system.This applies to applications where multiple units might share one zone sensor for both stand-alone (with communication wiring between units) and a building automation system.

Water Valve Override

The controller can be commanded via the Rover service tool or Tracer® TU to open all hydronic valves 100 percent.This allows for the faster water balancing of each unit and the entire system when the command is sent globally to all controllers. A properly balanced system is essential for proper and efficient operation.

Hydronic Coil Freeze Protection (Freeze Avoidance)

Systems in cold climates need to take precautions to avoid hydronic coil freeze-up.The controller does this from three different aspects. Any of these methods of protections will result in the unit fan being disabled, the outside air damper being shut, and the hydronic valves being opened 100 percent.

The three methods of freeze avoidance include:

1. A binary freeze protection thermostat is mounted on the coil and will cause a latching diagnostic if the coil temperature falls below 35°F.

2. An analog discharge air sensor monitors the temperature of the air coming off of the coil and if the temperature falls below 40°F the outside air damper is closed, the fan is turned off and the valves are fully opened.

3. When in the unoccupied mode, the controller has an adjustable freeze avoidance setpoint. If the outside air temperature is below the setpoint, the unit will open the valves to allow water to flow through the coils.

BCX-PRC001E-EN 93

Controls

Interoperability

Inter-operability allows the owner freedom to select multiple vendors, and multiple products.With this advantage, the owner can choose the best products, the best application, and the best service from a variety of suppliers to meet their evolving building control needs in a cost effective manner.

Generic Binary Input/Output

The three generic binary inputs/outputs are not part of the normal control, but are actually controlled through the Tracer® SC or Tracer® Summit system (when present) to issue commands to the controller to turn the generic inputs/outputs of add-on equipment (such as baseboard heating, exhaust fans, occupancy sensors, lighting, etc.) on and off.This binary port is not affected when other binary diagnostics interrupt unit operation.

Tracer® Controls Sequence of Operation

Fan Speed Switch (units with 3-speed fan only)

Off: Fan is turned off.

High, medium, or low: Fan runs continuously at the selected speed.

Tracer® ZN010 and ZN510

Off: Fan is off; control valves and the low air temperature detection option are still active.

Auto (Fan Cycling): The fan and mixing box damper cycle with control valve option to maintain setpoint temperature. If the unit has three-speeds, in cooling mode the fan cycles from off to high and in heating mode it cycles from off to low (factory default that can be field-adjusted using Rover service software). When no heating or cooling is required, the fan is off and the mixing box damper option closes. Units with three speeds can also be field-configured using Rover to run at a defined speed when the fan speed control is in the auto position.

Low, Medium, or High (Continuous Fan): The fan operates continuously while control valve option cycles to maintain setpoint temperature. The mixing damper option is open.

Tracer® ZN520 and UC400-B

Off: Fan is off; control valve options and mixing box damper options close. The low air temperature detection option is still active.

Auto: Fan speed control in the auto setting allows the modulating control valve option and single- or three-speed fan to work cooperatively to meet precise capacity requirements, while minimizing fan speed (motor/energy/acoustics) and valve position (pump energy/chilled water reset). As the capacity requirement increases at low fan speed, the water valve opens. When the low fan speed capacity switch point is reached, the fan switches to the next higher speed and the water valve repositions to maintain an equivalent capacity. The reverse sequence takes place with a decrease in required capacity.

Units with three-speed fans on low, medium, or high: The fan runs continuously at the selected speed and the valve option cycles to meet setpoint.

Figure 84. Low temperature detection device

When the low temperature detection device senses an entering air temperature of 36°F to the hydronic coil, the normally-closed switch opens a corresponding set of binary input terminals. The fan disables, control valves open, and the fresh air damper closes.

Thirty minutes after the diagnostic, Tracer® ZN010, ZN510, or ZN520 uses an automatic reset function to attempt to reset the unit. If the diagnostic occurs again within 24 hours after an automatic diagnostic reset, the unit will require a manual reset. This function attempts to resolve the infrequent nuisance alarm.

The low temperature detection device is an averaging type capillary tube and will reset when it detects an entering air temperature of at least 44°F.

Figure 85. Condensate overflow detection device

A float switch is factory-supplied for field installation in the auxiliary drain pan to detect a high condensate water level. When the float switch rises, the normally closed input opens a corresponding set of binary input terminals. With Trane controls installed, this also causes the fan to disable, and the control valve and fresh air damper options to close. Although the float switch will close when the high condensate level recedes, the controller must be manually reset before normal unit operation can occur. If using a Tracer® ZN510, ZN520 or UC400-B controller you can reset using Tracer® Summit. Use Rover service software to reset units with Tracer® ZN010, ZN510, or ZN520 and Tracer® TU for units with a UC400-B. When wired to the CSTI, the switch does not de-energize the unit when open position occurs. This is a dry contact only and sequence of operation of unit when this condition is reached is the responsibility of the field provided controller or thermostat.

Outside Air Sensor

The outside air sensor is field-mounted before the fan to sense the outside air temperature, primarily for use in economizer applications or as a status value when available for other applications.

Two-Position Mixing Box Damper Actuator

Note: Not available with Tracer® ZN520 controller.

This damper actuator uses a 24V signal. It allows zero to 50 percent fresh air. The damper will drive open to an adjustable mechanical stop-position whenever the fan is running during occupied mode and will spring-return closed when the fan turns off. The two-position damper ships separate for field installation.

Note: Trane highly recommends using the low temperature detection option with mixing box dampers to detect possible freeze conditions.

Discharge Air Sensor

The discharge air sensor is factory-mounted on the fan housing downstream of the coils for use as a status point or with other control algorithms. On units with optional electric heat, the sensor is field-mounted in the ductwork, downstream of the unit discharge.

Economizer Damper Actuator

Note: Available with Tracer® ZN520 and UC400-B controllers only.

This option is a modulating, spring-return damper actuator and is factory-wired and mounted to the mixing box damper assembly. When the controller enables the economizer damper and the unit is in occupied mode, the damper modulates between its minimum position (configurable) and the full open position to maintain setpoint temperature. If economizer operation stops or if the unit is in the heating mode, the damper adjusts to its minimum position.

Note: Trane highly recommends using the low temperature detection option with a mixing box damper to detect possible freeze conditions.

CO2 Sensor for Demand-Controlled Ventilation

Note: Available with Tracer® UC400-B controller only.

The unit is provided with a CO2 sensor to enable demand-controlled ventilation (DCV). This sensor provides a 4-20mA signal and ships separate for field installation (wired to Ul1). DCV can be used for modulating ECM, single-speed, two-speed, three-speed. It functions during occupied modes (Occupied, Occupied Standby, Occupied Bypass), in either heating or cooling mode, as long as the fan is operating (high, medium, low, On, or Auto). Refer to BAS-SVX48*-EN Tracer® UC400-B Programmable Controller for Blower Coil, Fan Coil, and Unit Ventilator Installation, Operation, and Programming manual for a description of DCV control and guidance in determining the appropriate CO2 and economizer damper setpoints for a given application.

Humidity Sensor

Note: Available with Tracer® ZN520 and UC400-B controllers only.

The humidity sensor is communicated value or with a local humidity sensor.

Controls

Control Valves

Three-way valve options allow either full waterflow through the coil or diverted waterflow through the bypass.

Two-Position Control Valves

Two-position valve options are spring-return or capacitor discharge-return types. Valves respond to a 24V signal and will either fully open or close. These valves cannot be driven or actuated to a partially open or closed position. If the valve loses power, the valve returns to its de-energized position.

Modulating Control Valves

Modulating control valves offer an alternative for more precise capacity control by modulating or varying the water flow through the coil. The valve responds to a 24V signal from the controller, which determines the valve position by a control algorithm. If the valve loses power, it remains in the position it was in when the power loss occurred.

Field-Supplied Valves

This option allows the controller to be factory-configured for the normal position of the field-supplied valve, as well as running a wiring harness from the control box to the piping side of the unit. When the field-supplied valve option is chosen, the control box is provided with low voltage components and wired back to a terminal strip (CSTI) or controller.

Note: Trane does not recommend wild coil applications.

How to Choose the Correct Control Valve

Valve flow coefficient or Cv, is defined as the volume of water flow through a control valve in the fully open position with a 1 psig differential across the valve. It is calculated using the following formula:

– Cv = Q/Square root ΔP where:

– Cv = flow coefficient

– Q = flow rate (Gpm)

– ΔP = pressure drop across the valve or coil (psig).

Branch authority or β (modulating valves only), which is represented by the following formula:

– β = pressure drop across the valve divided by the pressure drop across the branch circuit* x 100% = ΔP valve/ΔP branch circuit. * Branch circuit includes the coil and piping package (control valve, circuit setter, ball valves, fittings, and piping) between the supply and return riser.

Note: For good control, β should be between 25 and 70 percent.

Units with either the control interface or any of the Tracer® controllers (Tracer® ZN010, ZN510, ZN520, or UC400-B) are available with chilled and/or hot water control valves for each coil configuration. Control valve options are available as:

• Modulating

• Two-position, normally-open or normally-closed

• Two- or three-way configurations

• With sweat connections

See the valve availability table for a complete list of available valve options by size.

Modulating Valve Selection Example

Assume a size 12 blower coil is selected to operate at the following conditions:

Blower Coil

Entering water temperature = 45°F

Leaving water temperature = 55°F

EAT conditions = 80/67.

The coil is selected as a four-row coil.

Select the best modulating valve size for this unit.

1. Find the ΔP across the water coil. Refer to the AHRI performance table to determine the ΔP across the water coil (or use TOPSS™ selection program). The water pressure drop is found to be 7.0’ of water at a flow rate of 3.74 gpm. This converts to a pressure drop of 3.03 psig (1.0 feet of water = 0.4328 psig.)

2. Calculate the Cv of the water coil.

Cv = Gpm/Square root ΔP

Cv = 3.74/Square root 3.03

Cv = 2.15

Therefore, the valve with the Cv of 2.3 should be selected since it has the Cv which is closest to the Cv of the water coil.

Minimum Circuit Ampacity (MCA) and Maximum Fuse Size (MFS) Calculations

for Units with Electric Heat

Heater amps = (heater kW x 1000) / heater voltage

Notes: Use 120 V heater voltage for 115 V units. Use 240 V heater voltage for 230 V units.Use 208 V heater voltage for 208 V units. Use 277 V heater voltage for 277 V units. Use 480 V heater voltage for 460 V units.

MCA = 1.25 x (heater amps + all motor FLAs) MFS or HACR type circuit breaker = (2.25 x motor FLA) + heater amps

HACR (Heating, Air-Conditioning, and Refrigeration) type circuit breakers are required in the branch circuit wiring for all units with electric heat.

Select a standard fuse size equal to the calculated MFS. Use the next smaller size if the calculated MFS does not equal a standard size.

Standard fuse sizes: 15, 20, 25, 30, 35, 40, 45, 50, 60 amps

Casings

Casings (structural components) are constructed of heavy-gauge galvanized steel, insulated with one-inch, 1-1/2 lb density fiberglass fire resistant and odorless glass fiber material to provide thermal and acoustical insulation. Fan housing sides are directly attached to the air handler top and bottom panels strengthening the entire unit assembly. Coil access panels are located on both sides of BCHD/BCVD air handlers and allow easy removal of the internal coils and drain pan. Coil access is located on the front of the BCCD model. Main access panels provide generous access to the fan and motor from both sides of the BCHD/BCVD air handler, and the front of the BCCD unit.

Coils

Hydronic Coils

Cooling coils are four- or six-row, chilled water. Heating coils are one- or two-row hot water. Heating coils are available factory-installed in the preheat or reheat position. All hydronic coils are 12 fins per inch. All hydronic coils use highly efficient aluminum fins, mechanically bonded to seamless copper tubes. All coils are specifically designed and circuited for water use. All coils are factory tested with 450 psi air under water. Maximum standard operating conditions are: 300 psig, 200°F. Sweat type connections are standard. Coil performance data is in accordance with the current edition of AHRI Standard 410.

Direct Expansion (DX) Coils

DX coils use refrigerant 410A, have 3/8” OD x 0.014” W round seamless copper tubes expanded into full fin collars for permanent fin-tube bond. Three-, four-, and six-row DX coils use highly efficient aluminum fins mechanically bonded to stainless copper tubes with 12 fins per inch fin spacing.

The coil casing is 16-gauge galvanized steel. A foam sealing strip between the casing (top and bottom) channels and fins helps eliminate air bypass and reduce potential water carryover. Coils have round, seamless, copper pipe liquid lines and suction headers with male sweat connections. Suction headers have bottom connections to aid drainage of any oil that may collect in the coil. Liquid line and suction connections are outside the unit casing (on the same side of the unit) to facilitate field piping. Connections are clearly labeled to ensure coils are piped correctly. Coils have a venturi-type distributor assembly designed with a vertical downflow feed for low pressure drops.

Coils are proof tested at 715 psig and leak tested at 650 psig air-under-water. Coils are dehydrated and sealed with a dry air charge. Maximum standard operating conditions are 650 psig at 127°F with R-410A. Coil performance data is in accordance with the current edition of AHRI Standard 410.

BCX-PRC001E-EN 121


Steam Coils (Type NS)

A one-row steam distributing coil section is available in the pre-heat position. Steam coils are non-freezing and are pitched to ensure adequate condensate drainage. Coils have 1” OD x 0.031” W round seamless copper condensing tubes expanded into full fin collars for permanent fin-tube bond. Coil headers are cast iron for permanent leak-tight joints. Coils have continuous Sigma-Flo™ aluminum fins with full fin collars for maximum fin-tube contact and accurate spacing at 6 fpi. The coil casing is 16-gauge galvanized steel. Coil headers are gray cast iron with NPT internal thread connections.

Supply, return, and vacuum breaker connections are located at the same end of the unit and clearly labeled to ensure coils are piped correctly. Distributor tubes are 11/16” OD copper. Also, they have die-formed, accurately-spaced directional kinetic orifices that discharge steam in the direction of condensate flow (toward the return connection) to ensure even steam distribution across the coil face area and push out condensate. Distributor tubes are located concentrically within condensing tubes using corrosion resistant support clips. Supply header steam deflectors prevent impingement of steam into tubes in supply connection area.

Coils are proof tested at 300 psig and leak tested at 200 psig air-under-water. Maximum standard operating conditions are 15 psig at 400°F. Coil performance data is in accordance with the current edition of AHRI Standard 410.

Fan

The fans are DWDI (double width double inlet) forward curved centrifugal blower type. The fans are direct drive mounted directly to the motor shaft. All fans are dynamically balanced. All air handlers have a single fan.

EC Motors

A 50/60 Hertz, variable speed, multiple voltage EC motor has a plus or minus 10 percent voltage utilization range. The motor is open type with permanently sealed ball bearings, internal overload protection, and uses a radial mount. The motor is factory installed, programmed, and wired to the air handler control panel.

All motors are brushless DC (BLDC)/electronically commutated motors (ECM) factory-programmed and run-tested in assembled units. The motor controller is mounted in a touch-safe control box with a built-in integrated user interface and LED tachometer. If adjustments are needed, motor parameters can be adjusted through momentary contact switches on the motor control board accessible without factory service personnel.

Motors will soft-ramp between speeds to lessen the acoustics due to sudden speed changes. Motors can be operated at single speed, three speeds or with single zone VAV control. The motor will choose the highest speed if there are simultaneous/conflicting speed requests.

All motors have integral thermal overload protection and are permanently lubricated. BCHD/BCVD single-phase motors have a maximum ambient operating temperature of 104°F and three-phase motors have a maximum ambient operating temperature of 130°F. BCCD motors have a maximum ambient operating temperature of 104° F. Motors are capable of operating at 90 percent of rated voltage on all speed settings. Motors can operate up to 10 percent over voltage.

Drain Pan

The drain pan is noncorrosive and double-sloped to allow condensate drainage. The drainpan construction is polymer or optional stainless steel. Coils mount above the drain pan—not in the drain pan—thus allowing the drain pan to be fully inspected and cleaned. The drain pan can also be removed for cleaning. The polymer drain pan connections are unthreaded 3/4-inch schedule 40 PVC for solvent bonding. The stainless steel drain pan connection is 3/4-inch NPT schedule 40 stainless steel pipe. The main drain connection is at the lowest point of the drain pan. An auxiliary drain connection is provided on the same side as the main connection for BCHD/BCVD. BCCD
