Section 2: Installation Introduction

Components

Master Contactor: Energizes Compressor and optional Hydronic Pump and/or Desuperheater pump package.

Logic Board: Logic Board operates the compressor and protects unit by locking out when safety switches are engaged. It also provides fault indicator(s).

Terminal Strip: Provides connection to the thermostat or other accessories to the low voltage circuit.

Transformer: Converts incoming (source) voltage to 24V AC.

Low Voltage Breaker: Attached directly to transformer, protects the transformer and low voltage circuit.

Reversing Valve: Controls the cycle of the refrigerant system (heating or cooling). Energized in cooling mode.

High Pressure Switch: Protects the refrigerant system from high refrigerant pressure, by locking unit out if pressure exceeds setting.

Low Pressure Switch: Protects the refrigerant system from low suction pressure, if suction pressure falls below setting.

Flow Switch (Freeze Protection Device): Protects the water heat exchanger from freezing, by shutting down compressor if water flow decreases.

Compressor (Copeland Scroll): Pumps refrigerant through the heat exchangers and pressurizes the refrigerant, which increases the temperature of the refrigerant.

Shipping Bolts: This unit is equipped with the new COMPRESSOR ISOLATION feature. Do not loosen or remove the bolts.


Consumer Instructions: Dealer should instruct the consumer in proper operation, maintenance, filter replacements, thermostat and indicator lights. Also provide the consumer with the manufacturer’s Owner's Manual for the equipment being installed.

Enertech Global D-I-Y Policy: Enertech Global’s geothermal heat pumps and sys-tem installations may include electrical, refrigerant and/or water connections. Federal, state and local codes and regulations apply to various aspects of the installation. Improperly installed equipment can lead to equipment failure and health/safety con-cerns. For these reasons, only qualified technicians should install a Enertech Global built geothermal system.

Because of the importance of proper installation, Enertech Global does not sell equipment direct to homeowners. Internet websites and HVAC outlets may allow for purchases directly by homeowners and do-it-yourselfers, but Enertech Global offers no warranty on equipment that is purchased via the internet or installed by persons without proper training.

Enertech Global has set forth this policy to ensure installations of Enertech Global geothermal systems are done safely and properly. The use of well-trained, qualified technicians helps ensure that your system provides many years of comfort and savings.

Equipment Installation: Special care should be taken in locating the unit. All units should be placed on a formed plastic air pad, or a high density, closed cell polystyrene pad slightly larger than the base of the unit. All units should be located in an indoor area were the ambient temperature will remain above 55°F and should be located in a way that piping and ductwork or other permanently installed fixtures do not have to be removed for servicing and filter replacement.

Electrical: All wiring, line and low voltage, should comply with the manufacturer's recommendations, The National Electrical Code, and all local codes and ordinances.Thermostat: Thermostats should be installed approximately 54 inches off the floor on an inside wall in the return air pattern and where they are not in direct sunlight at anytime.

Loop Pumping Modules: Must be wired to the heat pump’s electric control box. A special entrance knockout is provided below the thermostat entrance knockout. A pump module connection block, connected to the master contactor, and circuit breaker is provided to connect the Pump Module wiring.

Desuperheater Package: Water heating is standard on all residential units (units may be ordered without). It uses excess heat during both heating and cooling cycles, to provide hot water for domestic needs. A double wall desuperheater exchanger (coil) located between the compressor and the reversing valve, extracts superheated vapor to heat domestic water; still satisfying its heating and cooling needs. The water circulation pump comes pre-mounted in all residential units, but must be electrically connected to the master contactor. Leaving it disconnected ensures that the pump will not run without a water supply.

The Desuperheater package can make up to 60% (depending on heat pump usage) of most domestic water needs, but a water heater is still recommended.

Desuperheater Piping: All copper tubes & fittings should be 5/8” O.D (1/2” nom) minimum with a maximum of 50ft separation. Piping should be insulated with 3/8” wall closed cell insulation.

Note: Copper is the only approved material for piping the desuperheater.

Section 3: Operation Considerations

Operation ConsiderationsEnertech recommends the aquastat setting not be set above 110°F for the storage tank temperature. Excessive vibration and part failure can occur at higher than recommended temperature settings. The higher operating temperatures cause substantial efficiency and capacity reductions.

The performance is negatively affected as the unit operates at the higher water temperatures and it benefits the unit and the homeowner to operate at or below the recommended water temperature of 110°F. With the lower efficiency created by higher water temperatures, the output capacity of the unit is decreased along with the efficiency. When operating at the higher entering water temperature the heat of extraction is significantly reduced, as well. In order to maintain the needed capacity, more of the heat is coming from the compressor working harder to compress the refrigerant.

The illustration below shows the parameters which are safe for compressor operation. Based on the leaving load water of 120°F, the loop would have to maintain 35°F to operate within the acceptable operating conditions for the compressor. Once your loop temperatures drop below 35°F, the acceptable leaving load temperature drops below 120°F. If you are designing loops for 30°F, the recommended leaving load temperature is 110°F. Because the water-to-water machines have become so popular for providing heated water for a multitude of uses, we’ve provided the above chart for reference.

The obvious correlation is that the warmer the Source Entering Water Temperature, the hotter the Load Leaving Water Temperature can be, to a point. R410A can only handle up to about 125°F Load Leaving Water Temperature before putting the compressor at risk.

Actual usage, and choices of heat distribution devices need to follow the acceptable operating conditions presented in the chart. If a question arises, please consult the Technical Services Department.


Buffer Tanks:Virtually all water-to-water heat pumps used for hydronic applications require a buffer tank to prevent equipment short cycling, and to allow lower flow rates through the water-to-water unit than through the hydronic delivery system. The following are considerations for buffer tank sizing.

• The size of the buffer tank should be determined based upon the predominant use of the water-to-water equipment (heating or cooling).

• The size of the buffer tank is based upon the lowest operating stage of the equipment. For example, a water-to-water heat pump with a two-stage compressor or two compressors may be sized for first stage capacity, reducing the size of the tank (two-stage aquastat required).

• Pressurized buffer tanks are sized differently than non-pressurized tanks (see guidelines listed below).

Pressurized buffer tanks for predominately heating applications should be sized at one (1) U.S. gallon per 1,000 Btuh of heating capacity (10 gallons per ton may also be used) at the maximum entering source water temperature (EST) and the minimum entering load water temperature (ELT), the point at which the water-to-water unit has the highest heating capacity, usually 50-70°F EST and 80-90°F ELT.

For predominately cooling applications, pressurized buffer tanks should be sized at one (1) U.S. gallon per 1,000 Btuh of cooling capacity (10 U.S. gallons per ton may also be used) at the minimum EST and the maximum ELT, the point at which the water-to-water unit has the highest cooling capacity, usually 50-70°F EST and 50-60°F ELT.

Select the size of the tank based upon the larger of the calculations (heating or cooling).

Non-pressurized buffer tanks must also be sized based upon predominate use (heating or cooling) and based upon the lowest capacity stage. Requirements for storage are less according to the manufacturer of the HSS series non-pressurized buffer tank. Using the same conditions for maximum heating and cooling capacity mentioned above, non-pressurized buffer tanks require 6 U.S. gallons per ton.

Section 3: Buffer Tanks

Unit Placement:When installing a geothermal heating and cooling unit, there are several items the installer should consider before placing the equipment.

1. Service Access. Is there enough space for service access? A general rule of thumb is at least 2 feet in the front and 2 feet on at least one side.

2. Unit Air Pad. All geothermal heating and cooling equipment should be placed on either a formed plastic air pad, or a high density, closed cell polystyrene pad. This helps eliminate vibration noise that could be transmitted through the floor.

3. If units are being placed on racking, the unit must be placed on a solid foundation covering the full base of the unit. Also, utilize a foam pad between the unit and the rack.

4. The installer must verify that all applicable wiring, piping, and accessories are correct and on the job site.

Pre-InstallationBefore you fully install the geothermal equipment, it is recommended you go through this quick checklist before placing the equipment.

⧠ Fully inspect the unit after unpacking.

⧠ Locate the Unit Start-Up form from this manual and have it available as the unit installation proceeds.

Open Loop PipingPlacement of the components for an open loop system are important when considering water quality and long term maintenance. The water solenoid valve should always be placed on the outlet of the heat pump, which will keep the heat exchanger under pressure when the unit is not operating. If the heat exchanger is under pressure, minerals will stay in suspension. Water solenoid valves are also designed to close against the pressure, not with the pressure. Otherwise, they tend to be noisy when closing.

A flow regulator should be placed after the water solenoid valve. Always check the product specification catalog for proper flow rate. A calculation must be made to determine the flow rate, so that the leaving water temperature does not have the possibility of freezing.

Other necessary components include a strainer, boiler drains for heat exchanger flushing, P/T ports and ball valves. Ball valves allow the water to be shut off for service, and also help when velocity noise is noticeable through the flow regulator. Spreading some of the pressure drop across the ball valves will lessen the velocity noise. Always double check flow rate at the P/T ports to make sure the ball valve adjustments have not lowered water flow too much, and essentially taken the flow regulator out of the equation. It’s a good idea to remove the

ball valve handles once the system is completed to avoid nuisance service calls.

Hose kits are optional, but make for an easier installation, since the P/T ports and connections are included. The hose also helps to isolate the heat pump from the piping system.

Since the heat pump can operate at lower water flow on first stage, two stage units typically include two water solenoid valves to save water. The flow regulators should be sized so that when one valve is open the unit operates at first stage flow rate, and when both valves are open, the unit operates at full load flow rate. For example, a 4 ton unit needs approximately 4 GPM on first stage, and approximately 7 GPM at full load. The flow regulator after the first valve should be 4 GPM, and the flow regulator after the second valve should be 3 GPM. When both valves are open, the unit will operate at 7 GPM.

Water QualityThe quality of the water used in geothermal systems is very important. In closed loop systems the dilution water (water mixed with antifreeze) must be of high quality to ensure adequate corrosion protection. Water of poor quality contains ions that make the fluid “hard” and corrosive. Calcium and magnesium hardness ions build up as scale on the walls of the system and reduce heat transfer. These ions may also react with the corrosion inhibitors in glycol based heat transfer fluids, causing them to precipitate out of solution and rendering the inhibitors ineffective in protecting against corrosion. In addition, high concentrations of corrosive ions, such as chloride and sulfate, will eat through any protective layer that the corrosion inhibitors form on the walls of the system.

Ideally, de-ionized water should be used for dilution with antifreeze solutions since de-ionizing removes both corrosive and hardness ions. Distilled water and zeolite softened water are also acceptable. Softened water, although free of hardened ions, may actually have increased concentrations of

corrosive ions and, therefore, its quality must be monitored. It is recommended that dilution water contain less than 100 PPM calcium carbonate or less than 25 PPM calcium plus magnesium ions; and less than 25 PPM chloride or sulfate ions.

In an open loop system the water quality is of no less importance. Due to the inherent variation of the supply water, it should be tested prior to making the decision to use an open loop system. Scaling of the heat exchanger and corrosion of the internal parts are two of the potential problems. The Department of Natural Resources or your local municipality can direct you to the proper testing agency.

Please see Table 1 for guidelines.

Notes1. Hardness in ppm is equivalent to hardness in mg/l.2. Grains/gallon = ppm divided by 17.1.3. Unit internal heat exchangers are not recommended for pool applications or water outside the range of the table. Secondary heat exchangers are required for pool or other applications not meeting the requirements shown above.4. Saltwater applications (approx. 25,000 ppm) require secondary heat exchangers due to copper piping between the heat exchanger and the unit fittings. 5. Filter for maximum of 600 micron size.



Interior PipingAll interior piping must be sized for proper flow rates and pressure loss. Insulation should be used on all inside piping when minimum loop temperatures are expected to be less than 50°F. Use the table below for insulation sizes with different pipe sizes. All pipe insulation should be a closed cell and have a minimum wall thickness of 3/8”. All piping insulation should be glued and sealed to prevent condensation and dripping. Interior piping may consist of the following materials: HDPE, copper, brass, or rubber hose (hose kit only). PVC is not allowed on pressurized systems.

Table 2: Pipe Insulation

Typical Pressurized Flow Center InstallationThe flow centers are insulated and contain all flushing and circulation connections for residential and light commercial earth loops that require a flow rate of no more than 20 gpm. 1-1/4” fusion x 1” double o-ring fittings (AGA6PES) are furnished with the double o-ring flow centers for HDPE loop constructions. Various fittings are available for the double o-ring flow centers for different connections. See figure 2 for connection options. A typical installation will require the use of a hose kit. Matching hose kits come with double o-ring adapters to transition to 1” hose connection.

Note: Threaded flow centers all have 1” FPT connections. Matching hose kits come with the AGBA55 adapter needed to transition from 1” FPT to 1” hose.

Typical Non-Pressurized Flow Center InstallationStanding column flow centers are designed to operate with no static pressure on the earth loop. The design is such that the column of water in the flow center is enough pressure to prime the pumps for proper system operation and pump reliability. The flow center does have a cap/seal, so it is still a closed system, where the fluid will not evaporate. If the earth loop header is external, the loop system will still need to be flushed with a purge cart. The non-pressurized flow center needs to be isolated from the

flush cart during flushing because the flow center is not designed to handle pressure. Since this is a non-pressurized system, the interior piping can incorporate all the above-mentioned pipe material options (see interior piping), including PVC. The flow center can be mounted to the wall with the included bracket or mounted on the floor as long as it is properly supported.

APSMA PUMP SHARING MODULEThe pump sharing module, part number APSMA, is designed to allow two units to share one flow center. With the APSMA module, either unit can energize the pump(s). Connect the units and flow center as shown in Figure 6. Figure 7 includes a schematic of the board. The module must be mounted in a NEMA enclosure or inside the unit control box. Local code supersedes any recommendations in this document.

Antifreeze OverviewIn areas where minimum entering loop temperatures drop below 40°F, or where piping will be routed through areas subject to freezing, antifreeze is required. Alcohols and glycols are commonly used as antifreeze. However, local and state/provincial codes supersede any instructions in this document. The system needs antifreeze to protect the coaxial heat exchanger from freezing and rupturing. Freeze protection should be maintained to 15°F below the lowest expected entering loop temperature. For example, if 30°F is the minimum expected entering loop temperature, the leaving loop temperature could be 22 to 25°F. Freeze protection should be set at 15°F (30-15 = 15°F). To determine antifreeze requirements, calculate how much volume the system holds. Then, calculate how much antifreeze will be needed by determining the percentage of antifreeze required for proper freeze protection. See Tables 3a and 3b for volumes and percentages. The freeze protection should be checked during installation using the proper hydrometer to measure the specific gravity and freeze protection level of the solution.

Antifreeze CharacteristicsSelection of the antifreeze solution for closed loop systems require the consideration of many important factors, which have long-term implications on the performance and life of the equipment. Each area of concern leads to a different “best choice” of antifreeze. There is no “perfect” antifreeze. Some of the factors to consider are as follows (Brine = antifreeze solution including water):

Safety: The toxicity and flammability of the brine (especially in a pure form).

Cost: Prices vary widely.

Thermal Performance: The heat transfer and viscosity effect of the brine.

Corrosiveness: The brine must be compatible with the system materials.

Stability: Will the brine require periodic change out or maintenance?Convenience: Is the antifreeze available and easy to transport and install?

Codes: Will the brine meet local and state/provincial codes?

The following are some general observations about the types of brines presently being used:

Methanol: Wood grain alcohol that is considered toxic in pure form. It has good heat transfer, low viscosity, is non-corrosive, and is mid to low price. The biggest down side is that it is flammable in concentrations greater than 25%.

Ethanol: Grain alcohol, which by the ATF (Alcohol, Tobacco, Firearms) department of the U.S. government, is required to be denatured and rendered unfit to drink. It has good heat transfer, mid to high price, is non-corrosive, non-toxic even in its pure form, and has medium viscosity. It also is flammable with concentrations greater than 25%. Note that the brand of ethanol is very important. Make sure it has been formulated for the geothermal industry. Some of the denaturants are not compatible with HDPE pipe (for example, solutions denatured with gasoline).

Propylene Glycol: Non-toxic, non-corrosive, mid to high price, poor heat transfer, high viscosity when cold, and can introduce micro air bubbles when adding to the system. It has also been known to form a “slime-type” coating inside the pipe. Food grade glycol is recommended because some of the other types have certain inhibitors that react poorly with geothermal systems. A 25% brine solution is a minimum required by glycol manufacturers, so that bacteria does not start to form.

Ethylene Glycol: Considered toxic and is not recommended for use in earth loop applications.

GS4 (POTASSIUM ACETATE): Considered highly corrosive (especially if air is present in the system) and has a very low surface tension, which causes leaks through most mechanical fittings. This brine is not recommended for use in earth loop applications.

Antifreeze ChargingCalculate the total amount of pipe in the system and use Table 3a to calculate the amount of volume for each specific section of the system. Add the entire volume together, and multiply that volume by the proper antifreeze percentage needed (Table 3b) for the freeze protection required in your area. Then, double check calculations during installation with the proper hydrometer and specific gravity chart (Figure 8) to determine if the correct amount of antifreeze was added.

Plumbing Installation

Note: All plumbing and piping connections must comply with local plumbing codes.

1. Disconnect electricity to water heater.

2. Turn off water supply to water heater.

3. Drain water heater. Open pressure relief valve.

4. Remove drain valve and fitting from water heater.

5. Thread the ¾” MPT x 3-1/2” nipple into the water heater drain port. Use Teflon tape, or pipe dope on threads.

6. Thread the center port of the ¾” brass tee to the other end of the nipple.

7. Thread one of the copper adaptors into the end of the tee closest to the heat pump.

8. Thread the drain valve into the other end of the nipple.

9. Above the water heater, cut the incoming cold water line. Remove a section of that line to enable the placement of the copper tee.

10. Insert the copper tee in the cold water line.

11. Thread the remaining two ½”SWT x ¾”MPT copper adaptors into the ¾” FPT fittings on the heat pump, marked HWG IN and HWG OUT.

12. Run interconnecting ½” copper pipe from the HOT WATER OUT on the heat pump, to the copper adaptor located on the tee at the bottom of the water heater.

13. Run interconnecting ½” copper pipe from the HOT WATER IN on the heat pump, to the copper tee in the cold water line.

14. Install an air vent fitting at the highest point of the line from step 13 (assuming it’s the higher of the two lines from the heat pump to the water heater).

15. Shut off the valve installed in the desuperheater line close to the tee in the cold water line. Open the air vent and all shut off valves installed in the “hot water hot”.

16. Turn the water supply to the water heater on. Fill water heater. Open highest hot water faucet to purge air from tank and piping.

17. Flush the interconnecting lines, and check for leaks. Make sure air vent is shoutoff when water begins to drip steadily from the vent.

18. Loosen the screw on the end of the despuerheater pump to purge the air from the pump’s rotor housing. A steady drip of water will indicate the air is removed. Tighten the screw and the pump can be connected to the contactor or teminal block.

19. Install 3/8” closed cell insulation on the lines connecting the heat pump to the water heater.

20. Reconnect electricity to water heater.

Section 7: Desuperheater Installation

Desuperheater InstallationUnits that ship with the desuperheater function must be connected to the water heater/storage tank with the optionally offered Desuperheater Connection Kit or (as supplied by others) shown on the following sections of this manual.

Note: Desuperheater capacity is based on 0.4 GPM Flow per nominal ton at 90°F entering hot water temperature.

Note: Units that are shipped with a desuperheater do not have the desuperheater pump wires connected to the electrical circuit, to prevent accidentally running the pump while dry. Pump has to be connected to the electric circuit (master contactor) when the lines from the water heater are installed & air is removed.

⚠ WARNING ⚠TO AVOID SERIOUS INJURY, IT IS RECOMMENDED THAT AN ANTI-SCALD MIXING VALVE IS INSTALLED

ON THE HOT WATER SUPPLY LINE INTO THE HOME. EVEN THOUGH HOT WATER TANK

TEMPERATURES COULD APPEAR TO BE SET AT LOWER LEVELS, HIGH TEMPERATURE WATER

FROM THE DESUPERHEATER COULD RAISE TANK TEMPERATURES TO UNSAFE LEVELS.

TIP: Measure the distance above the floor or shelf that the water heater is setting on, to where the drain valve is located. This distance must be greater than one-half the width of the tee you’re about to install, or you won’t be able to thread the tee on to the water heater.

Microprocessor Features and Operation Enertech Global geothermal heat pump controls provide a unique modular approach for controlling heat pump operation. The control system uses one, two, or three printed circuit boards, depending upon the features of a particular unit. This approach simplifies installation and troubleshooting, and eliminates features that are not applicable for some units.

A microprocessor-based printed circuit board controls the inputs to the unit as well as outputs for status mode, faults, and diagnostics. A status LED and an LED for each fault is provided for diagnostics.

Removable low voltage terminal strips provide all necessary terminals for field connections. Not only are the thermostat inputs included, but there are also removable terminal strips for all of the accessory wiring for ease of installation and troubleshooting. Startup/Random StartThe unit will not operate until all the inputs and safety controls are checked for normal conditions. At first power-up, the compressor is energized after a five minute delay. In addition, a zero to sixty second random start delay is added at first power-up to avoid multiple units from being energized at the same time.

Short Cycle Protection A built-in five minute anti-short cycle timer provides short cycle protection of the compressor.

Component Sequencing DelaysComponents are sequenced and delayed for optimum space conditioning performance and to make any startup noise less noticeable.

Test Mode The microprocessor control allows the technician to shorten most timing delays for faster diagnostics by changing the position of a jumper located on the lockout board.

Water Solenoid Valve Connections Two accessory relay outputs at the terminal strip provide a field connection for two types of water solenoid valves, a standard 24VAC solenoid valve, or a 24VAC solenoid valve with an end switch. Additional field wiring is no longer required for operation of the end switch.

Loop Pump Circuit BreakersThe loop pump(s) and desuperheater pump on single compressor units are protected by control box mounted circuit breakers for easy wiring of pumps during installation. Dual compressor units only protect the desuperheater pump but do not protect the loop or load side pumps. All loop and load side pumps must be wired externally using relays and circuit breakers supplied by others. Circuit breakers eliminate the need to replace fuses.

Safety Controls The control receives separate signals for high pressure, low pressure, and low water flow. Upon a continuous 30-second measurement of the fault (immediate for high pressure), compressor operation is suspended (see Fault Retry below), and the appropriate LED flashes. Once the unit is locked out (see Fault Retry below), an output (terminal “L”) is made available to a fault LED at the thermostat (water-to-water unit has fault LED on the corner post).

Low Pressure: If the low pressure switch is open for 30 continuous seconds, the compressor operation will be interrupted, and the control will go into fault retry mode. At startup, the low pressure switch is not monitored for 90 seconds to avoid nuisance faults.

High Pressure: If the high pressure switch opens, the compressor operation will be interrupted, and the control will go into fault retry mode. There is no delay from the time the switch opens and the board goes into fault retry mode. There is also no delay of switch monitoring at startup.

Flow Switch: If the flow switch is open for 30 continuous seconds, the compressor operation will be interrupted, and the control will go into fault retry mode. At startup, the flow switch is not monitored for 30 seconds to avoid nuisance faults.

Fault Retry All faults are retried twice before finally locking the unit out. The fault retry feature is designed to prevent nuisance service calls. There is an anti-short cycle period between fault retries. On the third fault, the board will go into lockout mode.

Section 8: Controls


Over/Under Voltage Shutdown The lockout board protects the compressor from operating when an over/under voltage condition exists. The control monitors secondary voltage (24VAC) to determine if an over/under voltage condition is occurring on the primary side of the transformer. For example, if the secondary voltageis 18VAC, the primary voltage for a 240V unit would be approximately 180V, which is below the minimum voltage (197V) recommended by the compressor manufacturer. Under voltage (<18VAC) causes the compressor to disengage and restart when the voltage returns to >20VAC. Over voltage (>31VAC) causes the compressor to disengage and restart when the voltage returns to <29VAC.

When an O/U Voltage condition occurs, the board will initiate a fault, shut down the compressor, and start the five minute ASC period. All four fault LEDs will flash (HP + LP + FS + CO) and the thermostat “Call For Service” indicator will be illuminated. This feature is self-resetting. If voltage returns to normal range normal operation will resume if/when the ASC period is over (except if in lockout mode). If voltage is still out of range at the end of the ASC period the control will execute a Fault Retry. On the third fault within 30 minutes, the board will go into lockout mode and illuminate the “Call For Service” indica-tor. When normal operation is restored the four fault LED’s will stop flashing and the “Call For Service” indicator will turn off.

Intelligent Reset If the thermostat is powered off and back on (soft reset), the board will reset, but the last fault will be stored in memory for ease of troubleshooting. If power is interrupted to the board, the fault memory will be cleared.

Diagnostics The lockout board includes five LEDs (status, high pressure, low pressure, low water flow, condensate overflow) for fast and simple control board diagnosis. Below is a table showing LED function.

LED Color Location1 Function Normal Operation Fault Retry2 Lockout2

Green Top High Pressure OFF Flashing3 ON3

Orange 2nd Low Pressure OFF Flashing3 ON3

Red 3rd Water Flow OFF Flashing3 ON3

Yellow Not applicable on water-to-water unitsGreen Bottom Status Flashing4 Flashing5 Flashing4

Notes:1. Looking at the board when the LEDs are on the right hand side2. If all five lights are flashing, the fault is over/under voltage3. Only the light associated with the particular fault/lockout will be on or flashing.

For example, if a high pressure lockout has occurred, the top green light will be on. The orange, red, and yellow lights will be off

4. Status lights will be off when in test mode5. Flashes alternately with the fault LED

Table 4: LED Identification

Section 8: Controls


Hot Water Pump Control Controls for high water temperature and low compressor discharge line temperature prevent the hot water (desuperheater) pump from operating when the leaving water temperature is above 130°F, or when the compressor discharge line is too cool to provide adequate water heating.

Lockout Board Jumper SelectionThe lockout board includes three jumpers for field selection of various board features.

Water Solenoid Valve Delay (WSD): When the WSD jumper is installed, the “A” terminal is energized when the compressor is energized. When the jumper is removed, the “A” terminal is energized 10 seconds after the compressor. If using the Taco water solenoid valve (or a valve with an end switch), the unit terminal strip includes a means for connecting a valve of this type. The WSD jumper should be installed. If using a fast opening valve without an end switch, the jumper should be removed.

Test Mode (TEST)When the TEST jumper is installed, the board operates in the normal mode. When the jumper is removed, the board operates in test mode, which speeds up all delays for easier troubleshooting. When service is complete, the jumper must be re-installed in order to make sure that the unit operates with normal sequencing delays. While test jumper is removed, the status (bottom green light) will remain off.

Over/Under Voltage Disable (O/V)When the O/V jumper is installed, the over/under voltage feature is active. When the jumper is removed, the over/under voltage feature is disabled. On rare occasions, variations in voltage will be outside the range of the over/under voltage feature, which may require removal of the jumper. However, removal of the jumper could cause the unit to run under adverse conditions, and therefore should not be removed without contacting technical services. An over/under voltage condition could cause premature component failure or damage to the unit controls. Any condition that would cause this fault must be thoroughly investigated before taking any action regarding the jumper removal. Likely causes of an over/under voltage condition include power company transformer selection, insufficient entrance wire sizing, defective breaker panel, incorrect transformer tap (unit control box), or other power-related issues.

Electrical: Geothermal unit high voltage

wiring is installed correctly Geothermal unit high voltage

wiring and breaker are the correct size

Auxiliary electric heaters are wired and installed correctly

Circulating pumps are wired and fused (if necessary) correctly

Desuperheater pump is NOT wired, unless piping is complete and all air is purged

Low voltage wiring is correct and completely installed

Equipment Start-Up

1. Energize geothermal unit with high voltage.

2. Set the thermostat to “Heat” or “Cool.” Adjust set point to energize the unit. System will energize after delays expire (typically a five minute delay).

3. Check water flow with a flow meter (non-pressurized) or pressure drop conversion (pressurized). Pressure drop tables must be used to convert the pressure drop to GPM. The pressure drop can be obtained by checking water pressure in and water pressure out at the P/T ports.

4. Check the geothermal unit’s electrical readings listed in the Unit Electrical Data table.

5. Check the source water temperature in and out at the P/T ports (use insertion probe). Allow 10 minutes of operation before recording temperature drop.

6. Calculate the heat of extraction or heat of rejection.

Plumbing: Pipe and pump sizes are correct Air is purged from all lines Antifreeze is installed All valves are open, including

those on the flow center Condensate is trapped and piped

to the drain Ductwork:

Filter is installed and clean Packaging is removed from the

blower assembly Blower turns freely Canvas connections installed on

supply plenum & return drop

7. Check the temperature difference of the load coax (water-to-water) or air coil (water-to-air). P/T ports are recommended for use on the load side, but the line temperatures can be used to check the temperature difference.

8. Change the mode of the thermostat and adjust the set point to energize the unit. Check the data in opposite mode as the previous tests. Amp draws as well as temperature differences and flow rate should be recorded.

9. Check auxiliary heat operation by adjusting the thermostat set point 5°F above the room temperature in “Heat” mode or set thermostat to “Emergency." Record voltage, amperage, and air temperature difference.

Once this information is recorded, find corresponding entering water temperature column in Specification Manual for unit.Find pressure differential in PSI column in Spec Manual. Then read the GPM column in Spec Manual to determine flow in GPM.

2. Check leaving water temperature of unit.FORMULA: GPM x water temp diff, x 485 (antifreeze) or 500 (fresh water) = HE or HR in BTU/HR

A 10% variance from Spec Manual is allowed. Always use the same pressure gauge & temperature measuring device.Water flow must be in range of Specification Manual. If system has too much water flow, performance problems should be expected

Section 10: Troubleshooting


A: UNIT WILL NOT START IN EITHER CYCLE

Thermostat

Set thermostat on heating and highest temperature setting. Unit should run. Set thermostat on cooling and lowest temperature setting. Unit should run. Set fan to On position. Fan should run. If unit does not run in any position, disconnect wires at heat pump terminal block and jump R, G, Y. Unit should run in heating. If unit runs, replace thermostat with correct thermostat only.

Loose or broken wires Tighten or replace wires.Blown Fuse/ Tripped Circuit Breakers

Check fuse size, replace fuse or reset circuit breaker.Check low voltage circuit breaker.

Low Voltage Circuit Check 24 volt transformer. If burned out or less than 24 volt, replace. Before replacing, verify tap setting and correct if necessary.

Water Flow (runs for 30 sec)

If water flow is low (less than 3.5 GPM), unit will not start. Make sure Pump Module or solenoid valve is connected (see wiring diagram). Water has to flow through the heat exchanger in the right direction (see labels at water fitting connections) before the compressor can start. If water flow is at normal flow, use an ohmmeter to check if you get continuity at the flow switch. If no switch is open and flow is a normal flow, remove switch and check for stuck particles or bad switch.

B: UNIT RUNNING NORMAL, BUT SPACE TEMPERATURE IS UNSTABLE

ThermostatThermostat is getting a draft of cold or warm air. Make sure that the wall or hole used to run thermostat wire from the ceiling or basement is sealed, so no draft can come to the thermostat.Faulty Thermostat (Replace).


C: NO WATER FLOW

Pump Module

Make sure Pump Module is connected to the control box relay (check all electrical connections). For non-pressurized systems, check water level in Pump Module. If full of water, check pump. Close valve on the pump flanges and loosen pump. Take off pump and see if there is an obstruction in the pump. If pump is defective, replace. For pressurized systems, check loop pressure. Repressurize if necessary. May require re-flushing if there is air in the loop.

Solenoid valve Make sure solenoid valve is connected. Check solenoid. If defective, replace.

D: IN HEATING OR COOLING MODE, UNIT OUTPUT IS LOW

Water Water flow & temperature insufficient.

Load Side FlowCheck speed setting, check nameplate or data manual for proper speed, and correct speed setting.Check for dirty air filter—Clean or replace.Restricted or leaky ductwork. Repair.

Refrigerant charge Refrigerant charge low, causing inefficient operation. Make adjustments only after airflow and water flow are checked.

Reversing valve

Defective reversing valve can create bypass of refrigerant to suction side of compressor. Switch reversing valve to heating and cooling mode rapidly. If problem is not resolved, replace valve. Wrap the valve with a wet cloth and direct the heat away from the valve. Excessive heat can damage the valve. Always use dry nitrogen when brazing. Replace filter/drier any time the circuit is opened.

E: IN HEATING OR COOLING MODE, UNIT OUTPUT IS LOW

Heat pump will not cool but will heat. Heat pump will not heat but will cool.

Reversing valve does not shift. Check reversing valve wiring. If wired wrong, correct wiring. If reversing valve is stuck, replace valve. Wrap the valve with a wet cloth and direct the heat away from the valve. Excessive heat can damage the valve. Always use dry nitrogen when brazing. Replace filter/drier any time the circuit is opened.

Section 11: Unit Electrical Data

Proper Power Supply Evaluation: When any compressor bearing unit is connected to a weak power supply, starting current will generate a significant “sag” in the voltage reducing the starting torque of the compressor motor increasing the start time. This will influence the rest of the electrical system in the building by lowering the voltage to the lights. This momentary low voltage causes “light dimming”. The total electrical system should be evaluated by an electrician and HVAC technician. The evaluation should include connections, sizes of wires, and size of the distribution panel between the unit and the utility’s connection. The transformer connection and sizing should be evaluated by the electric utility provider.

⚠ CAUTION ⚠CHECK COMPRESSOR AMP DRAW TO VERIFY COMPRESSOR ROTATION ON THREE PHASE UNITS. COMPARE AGAINST

UNIT ELECTRICAL TABLES. REVERSE ROTATION RESULTS IN HIGHER SOUND LEVELS, LOWER AMP DRAW, AND INCREASED COMPRESSOR WEAR. THE COMPRESSOR INTERNAL OVERLOAD WILL TRIP AFTER A SHORT PERIOD OF OPERATION.

Notes:1. All line and low voltage wiring must adhere to the National Electrical Code and local codes, whichever is the most stringent.2. In determining the correct supply wire size and maximum length, reference NFPA 70, Section 310. If the calculation is close to the maximum allowable ampacity of a particular wire size, use the next size up. This will ensure that no adverse effects occur, such as light dimming and/or shortened compressor life.3. All fuses class RK-5. 4. Min/Max Voltage: 208/230/60 = 187-252, 460/60 = 432-5045.

Glossary

Section 11: Specification Glossary, Calculations

Notes:1. Desuperheater Capacity is based upon 0.4 GPM Flow per nominal ton at 90°F entering hot water temperature.2. Extrapolation data down to 25°F for heating and interpolation between EST & GPM data is permissible.3. EWT (Entering Water Temperature) is also called EST (Entering Source Temperature).4. Load flow rate is the same as the nominal source flow rate, approximately 3 GPM per ton.

Application Notes for Performance Data

Source Water Flow SelectionProper flow rate is crucial for reliable operation of geothermal heat pumps. The performance data shows three flow rates for each entering water temperature (EST column). The general “rule of thumb” when selecting flow rates is the following:

Top flow rate: Open loop systems (1.5 to 2.0 gpm per ton)Middle flow rate: Minimum closed loop system flow rate (2.25 to 2.50 gpm/ton)Bottom flow rate: Nominal (optimum) closed loop system flow rate (3.0 gpm/ton)

Although the “rule of thumb” is adequate in most areas of North America, it is important to consider the application type before applying this “rule of thumb.” Antifreeze is generally required for all closed loop (geothermal) applications. Extreme Southern U.S. locations are the only exception. Open loop (well water) systems cannot use antifreeze, and must have enough flow rate in order to avoid freezing conditions at the Leaving Source Water Temperature (LWT) connection.

Calculations must be made for all systems without antifreeze to deter-mine if the top flow rate is adequate to prevent LWT at or near freezing conditions. The following steps should taken in making this calculation:

Determine minimum EST based upon your geographical area.Go to the performance data table for the heat pump model selected and look up the the Heat of Extraction (HE) at the “rule of thumb” water flow rate (GPM) and at the design Entering Load Temperature (ELT).Calculate the temperature difference (TD) based upon the HE and GPM of the model.

TD = HE / (GPM x 500).Calculate the LWT.LWT = EST - TD.

If the LWT is below 35-38°F, there is potential for freezing conditions if the flow rate or water temperature is less than ideal conditions, and the flow rate must be increased.

Example 1:EST = 50°F, ELT = 95°F.Model 036 Full Load, heating. Flow rate = 5 GPM. HE = 33,600 Btuh.TD = 33,600 / (5 x 500) = 13.4°FLWT = 50 - 13.4 = 36.6°FWater flow rate should be adequate under these conditions.

Example 2:EST = 40°F, ELT = 95°F.Model 036 Full Load, heating. Flow rate = 5 GPM. HE = 28,700 Btuh.TD = 28,700 / (5 x 500) = 11.5°FLWT = 40 - 11.5 = 28.5°FWater flow rate must be increased.
