mounts, mass plate/viscoelastic dampening material and the compartment is totally insulated to make the quietest console unit on the market. Safety controls include low temperature (freezestat) and refrigerant high pressure switches. The con-trol box is hinged for easy access to all of the controls. The MicroTech III unit controller offers both standalone or com-municating (LonWorks or BACnet) control options.Each uses a printed circuit board for clean wiring and a low voltage control circuit with a 50 VA transformer. See “Con-trols” section for more detailed information. Main power is made to a chassis-mounted 2" x 4" (51mm x 102mm) junction box.The fan section employs McQuay's Gentleflo tangential system fan and efficient, two-speed PSC motor for selectable airflow and/or noise level. Access to the fan wheel is made through the top panel. The motor is secured to the chassis with three screws for easy service.Water piping connections are 5/8" O.D. copper tubing and terminate away from the side of the chassis in the piping compartment for easy access. Unique left- and right-hand piping (includes condensate and electrical) locations are avail-able. The 3⁄4" (19mm) I.D. flexible clear vinyl condensate drain tube is internally trapped and extends 14" (356mm) into the piping compartment for easy connection. Piping (electri-cal and condensate also) can enter through the back wall or through the floor within the subbase. The chassis allows for a piping compartment between the chassis and the cabinet.

Optional Factory Installed FeaturesBoilerless system electric heat eliminates the need for a boiler in the heat pump water loop. An electric heater is added to the discharge side of the fan scroll. If the entering water temperature falls to 58°F (15°C) the thermostat locks out compressor operation. On a call for heat, the electric heater is energized. When the entering water temperature raises, the unit will resume compressor operation on a call for heat. An emergency electric heat override plug allows for electric heat, if the compressor (mechanical) heat should fail. Each unit has various heater sizes to select from. Not available on 115 volt units. Not CSA listed.

Optional Extended End Pockets (High Sill Units)Optional extended cabinet end pocket for high sill units, pro-vides 11" of additional area inside the left or right end pocket for piping or a field-installed pump.

MicroTech® III Unit ControllerThe MicroTech III Unit Controller is a microprocessor-based control board conveniently located in the unit control box for easy access through a removable access panel. The stand-alone unit controller is a hard wired interface and provides all the necessary field connections. The board can be wired for 24-volt AC output to the wall thermostat by using terminals R & C. An LED annunciator is located on the front corner of the unit chassis to quickly check the operating status of the unit.

MicroTech III Operating FeaturesAssumes cycle fan operation-not continuous fan operation:■ Start-up – The unit will not operate until all the inputs

and safety controls are checked for normal conditions.■ Cooling mode – On a call for cooling, the compressor

and fan will start 0 to 30 seconds later. When the load is satisfied, the compressor and fan shut off.

■ Heating Mode – On a call for heating, the reversing valve is energized after 60 seconds and the compressor and fan start. When the load is satisfied, the compressor and fan shut off. The reversing valve is de-energized 60 seconds later.

■ Short Cycle Protection & Random Start – Each time the compressor stops, a new random compressor start-delay time between 180 and 240 seconds is generated. This prevents compressor short cycling and prevents units from starting simultaneously after coming back from an unoccupied cycle.

■ Unoccupied Mode – A simple “grounded” signal between terminals U and C (no power source required), puts the unit into the unoccupied mode for night setback operation.

■ Override Mode – A switch on the deluxe automatic changeover thermostat can be activated during the unoccupied mode to put the unit back into the occupied mode for two hours for after-hours heating or cooling.

■ Motorized Valve/Pump Restart – The IV/PR (H8) terminals on the The MicroTech III unit controller are used to energize (open) a motorized valve or start a water pump to get water circulating prior to starting the compressor on call for heating or cooling. The IV/PR (H8) terminal may be “daisy chained” between 200 units.

■ Brownout Protection – The MicroTech III unit controller measures the input voltage and will suspend compressor and fan operation if the voltage falls below 80% of the unit nameplate rated value. A unique LED status is generated and an output is available to a “fault” LED at the thermostat.

■ Unit Shutdown – A simple grounded signal puts the unit into the shutdown mode. Compressor and fan operations are suspended. A unique LED status is generated and an output signal is made available for connection to a “fault” LED at the thermostat.

■ CondensateOverflowProtection–The MicroTech III unit controller incorporates a liquid sensor at the top of

Control Features & Options

the drain pan. Upon sensing water flow, cooling operation is suspended. A unique LED status is generated and output is available to a “fault” LED at the thermostat. Heating operation is not suspended.

■ Remote Reset of Automatic Lockouts – The Remote Reset feature provides the means to remotely reset automatic lockouts generated by high-pressure and/or low-temperature faults. When the MicroTech III unit controller is in automatic lockout due to one of these faults, and the cause of the fault condition has been alleviated, energizing the O-terminal for 10 seconds or more will force the control board to clear the lockout. A unit power cycle can also be used to clear an automatic lockout if the conditions causing the fault have been alleviated.

■ Intelligent Reset – The Fault Retry feature helps to minimize nuisance trips of automatic lockouts caused by high-pressure and/or low-temperature faults. This feature clears faults the first two times they occur within a 24-hour period and triggers an automatic lockout on the 3rd fault. The retry count is reset to zero every 24 hours.

■ Equipment Protection Control – The MicroTech III unit controller receives separate input signals from the refrigerant high-pressure switch and the low suction line temperature sensor. In a high-pressure situation, compressor operation is suspended. In a low temperature situation, the unit goes into a defrost cycle where the unit is put into cooling operation for 60 seconds until the coaxial heat exchanger is free of ice. Each switch generates its own unique LED status and output is available to a “fault” LED at the thermostat if either situation exists.

Note: Most unit fault conditions are the result of operating the equipment outside the unit specifications.

Open Loop Well Water Applications: ARI 325 / ISO 13256-1 “Open Loop” well water systems use ground water to remove or add heat to the interior water loop. The key benefit of an open loop system is the constant water temperature, usually 50ºF to 60ºF, which provides efficient operation at a low first cost. Most commercial designers incorporate a heat exchang-er to isolate the building loop from the well water. Using heat exchangers can reduce maintenance issues while still allow-ing the transfer of heat from unit to unit as with the “Boiler/Tower System”. A successful design provides an ample amount of groundwater (approximately 2 GPM per ton) and adequate provisions for discharging water back to the aquifer or surface. Open Loop applications are commonly used in coastal areas where soil characteristics allow reinjection wells to return the water back to the aquifer. Note that some states have requirements on the depths of return water reinjection wells, and such wells must be approved by the United States Environmental Protection Agency. Also, bad water quality can increase problems with heat exchanger scaling. Suspend-ed solids can erode the heat exchanger. Strainers can be used to contain suspended solids.Figure 4: Open Loop Well Application

Applications

ApplicationsWater Source Heat Pump SystemsWater source heat pump systems are one of the most effi-cient, environmentally friendly systems available for heating and cooling buildings. High-efficiency, self contained units (sizes 7,000 btuh to 420,000 btuh) can be placed in virtually any location within a building. Each unit responds only to the heating or cooling load of the individual zone it serves. This permits an excellent comfort level for occupants, better control of energy use for building owners and lower seasonal operating costs. The Air-Conditioning Refrigeration Institute (ARI) and the International Standards Organization (ISO) publish standards so that water source heat pumps are rated for specific applications. The ARI/ISO loop options shown in this catalog are typical water source heat pump loop choices available in today’s market. These systems offer benefits ranging from low cost installation to the highest energy ef-ficiency available in the market today.

Boiler / Tower Applications: ARI 320 / ISO 13256-1A “Boiler/Tower” application uses a simple two-pipe water circulating system that adds heat, removes heat or transfers rejected heat to other units throughout the building. The water temperature for heating is generally maintained between 65ºF – 70ºF and is usually provided by a natural gas or electric boiler located in a mechanical room. The condensing water temperature, during cooling months, is maintained between 85ºF and 95ºF and requires the use of a cooling tower to dis-sipate waste heat. Cooling towers can be located on the roof, or inside or adjacent to the building. This application can be the lowest cost of the loop options available. Note: ASHRAE 90.1 standards require that circulating pumps over 10 HP will require use of “variable frequency drive” equipment and pipe insulation to be used whenever water temperatures are below 60 degrees and above 105 degrees. See ASHRAE 90.1 Standards for details.Figure 3: Boiler/Tower Application


Figure 6: Horizontal Loop Application

A “Surface Water” or “Lake” closed loop system is a geo-thermal loop that is directly installed in a lake or body of water that is near the building. In many cases, the body of water is constructed on the building site to meet drainage or aesthetic requirements. Surface loops use bundled polyethyl-ene coils that are connected in the same manner as a vertical or horizontal loop using a parallel reverse return design. The size and the depth of the lake is critical. Commercial design services should be used to certify that a given body of water is sufficient to withstand the building loads. Loop tempera-tures usually range from 35ºF to 90ºF and prove to be the best cooling performer and lowest cost loop option of the three geothermal loops. Some applications may not be good candi-dates due to public access or debris problems from flooding.Figure 7: Surface Water Loop Application

Applications

Closed Loop Geothermal Applications ARI 330/ISO 13256-1 “Vertical Closed Loop” applications are installed by drill-ing vertical bore holes into the earth and inserting a plastic polyethylene supply/return pipe into the holes. The vertical wells are connected in parallel reverse return fashion to allow the water from the building to circulate evenly throughout the borefield. The circulating fluid dissipates heat to the ground in a similar manner as a “tower” and adds heat back to the loop like a boiler. If properly designed, the loop field can maintain the loop temperatures necessary to condition the building without the use of a boiler or a tower. Loop tempera-tures usually range from 37ºF to 95ºF in Northern climates. Southern applications can see temperatures ranging from 40ºF to 100ºF. The number of bore holes and their depth should be determined by using commercial software that is specifi-cally designed for vertical geothermal applications. Typical bore depths of a vertical loop range from 150 to 400 feet and generally require about 250 feet of surface area per ton of cooling.Figure 5: Vertical Loop Application

A closed loop “Horizontal” geothermal application is simi-lar to a vertical loop application with the exception that the loops are installed in trenches approximately 5 feet below the ground surface. The piping may be installed using a “four-pipe” or “six-pipe” design and could require 1,500 to 2,000 square feet of surface area per ton of cooling. Loop temperatures for a commercial application can range from 35ºF to 95ºF in Northern climates. Southern climates can see temperatures ranging from 40ºF to 100ºF. Horizontal loops are generally not applied in urban areas because land use and costs can be prohibitive. New advances in installation proce-dures have improved the assembly time of horizontal loops while keeping the first cost lower than a vertical loop.


Condensate DrainThe factory provided condensate drain trap on the console unit is located inside the end cabinet. Condensate removal piping must be pitched away from the unit not less than 1/4" per foot. A vent is required after the trap so that the conden-sate will drain away from the unit. The vent can also act as a clean out if the trap becomes clogged. To avoid having waste gases entering the building, the condensate drain should not be directly piped to a drain/waste/vent stack. See local codes for the correct application of condensate piping to drains. McQuay has available optional fire-rated flexible hoses to better facilitate supply and return piping connections. These flexible hoses reduce vibration between the unit and the rigid piping system.

Application ConsiderationsTypical Console Installation

Unit LocationThe Console Water Source Heat Pump is typically installed on an exterior wall.Locate a Console unit to allow for easy removal of the filter and access panels. Allow a minimum of 18" (46 cm) clear-ance on each side of the unit for service and maintenance access. To reduce noise emissions, install a field-provided 1/4 inch thick, rubber isolator pad below the entire base of the unit. The pad should be equal to the overall foot-print size of the unit to provide sound dampening of the unit while in opera-tion. The unit must sit flat on the floor to prevent unwanted noise and vibration.

PipingThe console water source heat pump unit is typically con-nected to the supply / return piping using a “reverse return” piping system which includes a flow control device so that flow requirements are met for each zone. A short, high pres-sure “flexible hose” is used to connect the unit to the build-ing’s hard piping and acts as a sound attenuator for both the unit operating noise and hydronic pumping noise. One end of the hose has a swivel fitting to facilitate removal of the unit for replacement or service. Include supply and return shutoff valves in the design to allow removal of a unit without the need to shut down the entire heat pump system. The return valve may be used for balancing and will typically have a “memory stop” so that it can be reopened to the proper posi-tion for the flow required. Fixed flow devices are commer-cially available and can be installed to eliminate the need for memory stop shut off valves. Include Pressure / Temperature ports to allow the service technician to measure water flow and unit operation.

Applications


ApplicationsTypical Cooling and Heating Refrigeration Cycles (For standard heat pump operation only)Figure 9: Cooling Refrigeration CycleWhen the wall thermostat calls for COOLING, the reversing valve directs the flow of the refrigerant, a hot gas, from the compres-sor to the water-to-refrigerant heat exchanger. There, the heat is removed by the water, and the hot gas condenses to become a liq-uid. The liquid then flows through a thermal expansion valve to the air-to-refrigerant heat exchanger coil. The liquid then evapo-rates and becomes a gas, at the same time absorbing heat and cooling the air passing over the surfaces of the coil. The refrigerant then flows as a low pressure gas through the reversing valve and back to the suction side of the compressor to complete the cycle.

Unit SelectionAchieving optimal performance with water source heat pump systems requires both accurate system design and proper equipment selection. Use a building load program to determine the heating and cooling loads of each zone prior to making equipment selections. With this information, the McQuay SelectTools™ software selection program for Water Source Heat Pumps can be used to provide fast, accurate and complete selections of all McQuay water source heat pump products. SelectTools software is available by contacting your local McQuay Representative.While we recommend that you use McQuay SelectTools soft-ware for all unit selections, manual selections can be accom-plished using the same zone load information and the capacity tables available in this catalog.

Boiler / Tower Application Manual Selections:The following example illustrates a typical selection for a zone in a boiler/tower system for a commercial building.A building load program determines that this zone needs 10,430 Btuh of total cooling, 6,950 Btuh of sensible cool-ing and 9,150 Btuh of total heating. The water temperatures for the boiler/tower system are 90ºF for cooling and 70ºF for heating. The return air temperature is 80ºF dry bulb with 67ºF wet bulb for cooling and 70ºF for heating.

Zone Requirements: Total Cooling Load = 10,430 Btuh Sensible Cooling Load = 6,950 Btuh Total Heating Load = 9,150 Btuh Air Flow Required = 275 CFM Return Air Cooling = 80ºFDB/ 67ºFWB Return Air - Heating = 70ºFDBSince a McQuay Model MHC 009 produces approximately 10,000 Btuh of cooling, it is not sufficient for this zone and a model MHC 012 should be considered. Model MHC is chosen because it is specifically designed for a boiler/tower application. Typical water flow rates for boiler/tower ap-plications are 2.0 to 2.5 GPM per ton and in this example no antifreeze is used.

Selection:Model MHC 012 (Boilel/Tower)Total Cooling Capacity @ 90 EWT = 11,511 Btuh Sensible cooling capacity @ 90 EWT = 7,660 Btuh Total Heating Capacity @ 70 EWT = 14,160 Btuh CFM = 275Water Flow required to meet capacity = 8 GPM Water Pressure drop = 2.5 (FT. H2O)

Final Selection: MHC 012

Geothermal Applications:The following example illustrates the same zone in a geother-mal application.The load requirements for the zone are the same as the above example – 10,430 Btuh of total cooling and 6,950 Btuh of sensible cooling and 9,150 Btuh of heating. Geothermal loop software programs are available to help determine the size of the loop field based on: ■ Desired entering water temperatures for the system.■ Specific acreage available for the loop which produces

specific min./max loop temps for the unit selection.Entering water temperatures for geothermal systems can be as high as 90º to 100ºF and as low as 30ºF based on the geographical location of the building. Water flow rates are typically 2.5 to 3 GPM per ton and the use of antifreeze is required in most northern applications.

Zone Requirements:Total Cooling Load = 10,430 BTUH Sensible Cooling Load = 6,950 BTUH Total Heating Load = 9,150 BTUH Air Flow Required = 275 CFM Return Air Cooling = 80 DB / 67 WB Return Air - Heating = 70 DBA McQuay Model MHW is chosen for this geothermal ap-plication. Model MHW offers insulated water piping for condensation considerations and a different freezestat setting to allow entering water temperatures lower than 40ºF (with antifreeze). Output capacities should be recalculated using the antifreeze reduction tables that are shown on page 39. The Model MHW 012 is first considered but may not meet the heating load because of the reduced entering water tempera-tures (35ºF) and an antifreeze solution of 21 % propylene (see page 39).

Selection: Model MHC 012 (Geothermal model)Total cooling capacity @ 100 EWT = 10,555 Btuh × .980 = 10,344Sensible cooling capacity @ 100 EWT = 7,257 Btuh × .980 = 7,112Total heating capacity @ 35 EWT = 9,430 Btuh × .975 = 9,240CFM = 284Water Flow required to meet capacity = 2.4 GPM Water Pressure drop = 2.5 × 1.5 = 3.75 (FT. H2O)

EnvironmentThis equipment is designed for indoor installation only. Shel-tered locations such as attics, garages, etc., generally will not provide sufficient protection against extremes in temperature and/or humidity, and equipment performance, reliability, and service life may be adversely affected.

Power SupplyA voltage variation of +/-10% of nameplate voltage is accept-able.

Additional Information for Initial Start-Up OnlyStandard Range Units:Units are designed to start in an ambient of 50ºF (10ºC), with entering air at 50ºF (10ºC), with entering water at 70ºF (21ºC), with both air and water at the flow rates used in the ISO 13256-1 rating test, for initial start-up in winter.Note: This is not a normal or continuous operating condition.

It is assumed that such a start-up is for the purpose of bringing the building space up to occupancy temperature.

Wireless Temperature Control (T9000)The T9000 Wireless Temperature Control is designed to provide precision temperature control without the installation labor and expense of wiring. • Powered by AA batteries• Mounts in any suitable location that will provide good

temperature control. • Large LCD display provides the user with current room

temperature, set point temperature, time, program interval, and other system status information.

For detailed installation, operation refer to Operation & Main-tenance Bulletin OM 897-x.

Programmable Non-programmable The second part of the T9000 system is called a Remote Con-trol Node or “RCN”. An RCN interfaces with specific desired HVAC equipment, and communicates with its thermostat us-ing unlicensed 900 MHz, radio frequency energy. At the time of installation, the T9000 thermostat is linked to one or more RCN controls. The thermostat and RCN that have been linked will not interfere with, or be affected by, any other thermostat or RCN in adjacent rooms, apartments, or neighboring homes.

Remote Control Node (RCN)Used with the Wireless Temperature Control, the RCN inter-faces with specific HVAC equipment, and communicates with its thermostat using unlicensed 900 MHz, radio frequency en-ergy. Contact your local McQuay Representative for details.

Multiple Unit Control Panel (MUCP)

Figure 27: Multiple Unit Control Panel and Board

The Multiple Unit Control Panel (MUCP) is an accessory used when up to 3-units are controlled from a single thermo-stat. Console units must have the MUCP field-installed in a remote location, typically close to the units and convenient for service access.Note: The MUCP control board does not fit inside the

console unit control box.A maximum of 2 boards may be used together if up to 6-units must be connected and controlled from a single thermostat.Note: Multi-speed operation is only available with the

optional unit-mounted fan speed switch.

Figure 28: Multiple Unit Control Panel Ciruit Board

The multiple unit control board provides the components necessary to protect the MicroTech III unit controller from electrical damage that may occur when using standard off-the-shelf relays. This version of the board uses VAC relays and should not be used in combination with any other accessories or equipment that require VDC connections to the “G”, “W1”, or “Y1” terminals.
