General Information

� CAUTION! �

CAUTION! DO NOT store or install units in corrosive environments or in locations subject to temperature or humidity extremes (e.g., attics, garages, rooftops, etc.). Corrosive conditions and high temperature or humidity can signicantly reduce performance, reliability, and service life. Always move and store units in an upright position. Tilting units on their sides may cause equipment damage.

� CAUTION! �

CAUTION! CUT HAZARD - Failure to follow this caution may result in personal injury. Sheet metal parts may have sharp edges or burrs. Use care and wear appropriate protective clothing, safety glasses and gloves when handling parts and servicing heat pumps.

Unit Protection

Cover units on the job site with either shipping packaging, vinyl lm, or an equivalent protective covering. Cap the open ends of pipes stored on the job site. In areas where painting, plastering, and/or spraying has not been completed, all due precautions must be taken to avoid physical damage to the units and contamination by foreign material. Physical damage and contamination may prevent proper start-up and may result in costly equipment clean-up.

Examine all pipes, ttings, and valves before installing any of the system components. Remove any dirt or trash found in or on these components.

Pre-Installation

Installation, Operation, and Maintenance instructions are provided with each unit. The installation site chosen should include adequate service clearance around the unit. Before unit start-up, read all manuals and become familiar with the unit and its operation. Thoroughly check the system before operation. Prepare units for installation as follows:

1. Compare the electrical data on the unit nameplate with ordering and shipping information to verify that the correct unit has been shipped.

2. Keep the cabinet covered with the shipping packaging until installation is complete and all plastering, painting, etc. is nished.

3. Verify refrigerant tubing is free of kinks or dents and that it does not touch other unit components.

4. Inspect all electrical connections. Connections must be clean and tight at the terminals.

Unit Installation

Unit Location

These units are not designed for outdoor installation. Locate the unit in an INDOOR area that allows enough space for service personnel to perform typical maintenance or repairs.

The installation of water source heat pump units and all associated components, parts and accessories which make up the installation shall be in accordance with the regulations of ALL authorities having jurisdiction and MUST conform to all applicable codes. It is the responsibility of the Installing Contractor to determine

WATER CONNECTION INSTALLATION

Residential models using swivel piping ttings for water connections are rated for 450 psi (3101 kPa) operating pressure. The connections have a rubber gasket seal similar to a garden hose gasket, which when mated to the ush end of most 1” threaded male pipe ttings provides a leak-free seal without the need for thread sealing tape or joint compound. Insure that the rubber seal is in the swivel connector prior to attempting any connection (rubber seals are shipped attached to the swivel connector). DO NOT OVER TIGHTEN or leaks may occur.

and comply with ALL applicable codes and regulations.

Locate the unit in an indoor area that allows easy removal of access panels, and has enough space for service personnel to perform maintenance or repair. Provide sufcient room to make water and electrical connections.. Any access panel screws that would be difcult to remove after the unit is installed should be removed prior to setting the unit. These units are not approved for outdoor installation and, therefore, must be installed inside the structure being conditioned. Do not locate in areas subject to freezing or where humidity levels can cause cabinet condensation.

The female locking ring is threaded onto the pipe threads which holds the male pipe end against the rubber gasket, and seals the joint. HAND TIGHTEN ONLY! DO NOT OVERTIGHTEN!

FPT Connections (Size 120)

Pipe joint compound is not necessary when Teon threaded tape is pre-applied to hose assemblies or when ared-end connections are used. If pipe joint compound is preferred, use compound only in small amounts on the pipe threads of the tting adapters. Prevent sealant from reaching the ared surfaces of the joint.

Note: When anti-freeze is used in the loop, assure that it is compatible with Teon tape or pipe joint compound employed.

Maximum allowable torque for brass ttings is 30 ft-lbs [41 N-m]. If a torque wrench is not available, tighten nger-tight plus one quarter turn. Tighten steel ttings as necessary.

Ground-Loop Heat Pump Applications

� CAUTION! �

CAUTION! The following instructions represent industry accepted installation practices for closed loop earth coupled heat pump systems. Instructions are provided to assist the contractor in installing trouble free ground loops. These instructions are recommendations only. State/provincial and local codes MUST be followed and installation MUST conform to ALL applicable codes. It is the responsibility of the installing contractor to determine and comply with ALL applicable codes and regulations.

Pre-Installation

Prior to installation, locate and mark all existing underground utilities, piping, etc. Install loops for new construction before sidewalks, patios, driveways, and other construction has begun. During construction, accurately mark all ground loop piping on the plot plan as an aid in avoiding potential future damage to the installation.

Piping Installation

All earth loop piping materials should be limited to polyethylene fusion only for in-ground sections of the loop. Galvanized or steel ttings should not be used at any time due to their tendency to corrode. All plastic to metal threaded ttings should be avoided due to their potential to leak in earth coupled applications. A anged tting should be substituted. P/T plugs should be used so that ow can be measured using the pressure drop of the unit heat exchanger. Earth loop temperatures can range between 25 and 110°F [-4 to 43°C]. Flow rates between 2.25 and 3 gpm per ton [2.41 to 3.23 l/m per kW] of cooling capacity is recommended in these applications.

Test individual horizontal loop circuits before backlling. Test vertical U-bends and pond loop assemblies prior to installation. Pressures of at least 100 psi [689 kPa] should be used when testing. Do not exceed the pipe pressure rating. Test entire system when all loops are assembled.

Flushing the Earth Loop

Once piping is completed between the unit, the ow controller and the ground loop (Figure 1), the loop is ready for nal purging and charging. A ush cart with at least a 1.5 hp [1.1 kW] pump is required to achieve enough uid velocity in the loop piping system to purge air and dirt particles. An antifreeze solution is used in most areas to prevent freezing. All air and debris must be removed from the earth loop piping before operation. Flush the loop with a high volume of water at a minimum velocity of 2 fps (0.6 m/s) in all piping. The steps below must be followed for proper ushing.

1. Fill loop with water from a garden hose through the ush cart before using the ush cart pump to insure an even ll.

2. Once full, the ushing process can begin. Do not allow the water level in the ush cart tank to drop below the pump inlet line to avoid air being pumped back out to the earth loop.

3. Try to maintain a uid level in the tank above the return tee so that air cannot be continuously mixed back into the uid. Surges of 50 psi (345 kPa) can be used to help purge air pockets by simply shutting off the return valve going into the ush cart reservoir. This “dead heads” the pump to 50 psi (345 kPa). To purge, dead head the pump until maximum pumping pressure is reached. Open the return valve and a pressure surge will be sent through the loop to help purge air pockets from the piping system.

4. Notice the drop in uid level in the ush cart tank when the return valve is shut off. If air is adequately purged from the system, the level will drop only 1-2 inches (2.5 5 cm) in a 10” (25 cm) diameter PVC ush tank (about a half gallon [2.3 liters]), since liquids are incompressible. If the level drops more than this, ushing should continue since air is still being compressed in the loop uid. Perform the “dead head” procedure a number of times.

Note: This uid level drop is your only indication of air in the loop.

Antifreeze may be added before, during or after the ushing procedure. However, depending upon which time is chosen, antifreeze could be wasted when emptying the ush cart tank. See antifreeze section for more details.

Loop static pressure will uctuate with the seasons. Pressures will be higher in the winter months than during the cooling season. This uctuation is normal and should be considered when charging the system initially. Run the unit in either heating or cooling for a number of minutes to condition the loop to a homogenous temperature. This is a good time for tool cleanup, piping insulation, etc. Then, perform nal ush and pressurize the loop to a static pressure of 50-75 psi [345-517 kPa] (winter) or 35-40 psi [241-276 kPa] (summer). After pressurization, be sure to loosen the plug at the end of the Grundfos loop pump motor(s) to allow trapped air to be discharged and to insure the motor housing has been ooded. This is not required for Taco circulators. Insure that the Flow Controller provides adequate ow through the unit by checking pressure drop across the heat exchanger and compare to the pressure drop tables at the back of the manual.

Antifreeze

In areas where minimum entering loop temperatures drop below 40°F [5°C] or where piping will be routed through areas subject to freezing, antifreeze is required. Alcohols and glycols are commonly used as antifreeze; however your local sales manager should be consulted for the antifreeze best suited to your area. Low temperature protection should be maintained to 15°F [9°C] below the lowest expected entering loop temperature. For example, if 30°F [-1°C] is the minimum expected entering loop temperature, the

R e v. : 1 J u l y, 2 010

Ground-Loop Heat Pump Applications

leaving loop temperature would be 25 to 22°F [-4 to -6°C] and low temperature protection should be at 15°F [-10°C]. Calculation is as follows: 30°F - 15°F = 15°F [-1°C - 9°C = -10°C].

All alcohols should be premixed and pumped from a reservoir outside of the building when possible or introduced under the water level to prevent fumes. Calculate the total volume of uid in the piping system using Table 1. Then use the percentage by volume shown in Table 2 for the amount of antifreeze needed. Antifreeze concentration should be checked from a well mixed sample using a hydrometer to measure specic gravity.

Ground-Water Heat Pump Applications

Open Loop - Ground Water Systems

Shut off valves should be included for ease of servicing. Boiler drains or other valves should be “tee’d” into the lines to allow acid ushing of the heat exchanger. Shut off valves should be positioned to allow ow through the coaxial heat exchanger via the boiler drains without allowing ow into the piping system. P/T plugs should be used so that pressure drop and temperature can be measured. Piping materials should be limited to copper or PVC SCH80. Note: Due to the pressure and temperature extremes, PVC SCH40 is not recommended.

Water quantity should be plentiful and of good quality. Consult water quality table for guidelines. The unit can be ordered with either a copper or cupro-nickel water heat exchanger. Consult table 3 for recommendations. Copper is recommended for closed loop systems and open loop ground water systems that are not high in mineral content or corrosiveness. In conditions anticipating heavy scale formation or in brackish water, a cupro-nickel heat exchanger is recommended. In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, an open loop system is not recommended. Heat exchanger coils may over time lose heat exchange capabilities due to build up of mineral deposits. Heat exchangers must only be serviced by a qualied technician, as acid and special pumping equipment is required. Desuperheater coils can likewise become scaled and possibly plugged. In areas with extremely hard water, the owner should be informed that the heat exchanger may require occasional acid ushing. In some cases, the desuperheater option should not be recommended due to hard water conditions and additional maintenance required.

Water Quality Standards

Scaling potential should be assessed using the pH/ Calcium hardness method. If the pH <7.5 and the Calcium hardness is less than 100 ppm, scaling potential is low. If this method yields numbers out of range of those listed, the Ryznar Stability and Langelier Saturation indecies should be calculated. Use the appropriate scaling surface temperature for the application, 150°F [66°C] for direct use (well water/ open loop) and HWG (desuperheater); 85°F [29°C] for indirect use. A monitoring plan should be implemented in these probable scaling situations. Other water quality issues such as iron fouling, corrosion prevention and erosion and clogging should also be considered.

Expansion Tank and Pump

Use a closed, bladder-type expansion tank to minimize mineral formation due to air exposure. The expansion tank should be sized to provide at least one minute continuous run time of the pump using its drawdown capacity rating to prevent pump short cycling. Discharge water from the unit is not contaminated in any manner and can be disposed of in various ways, depending on local building codes (e.g. recharge well, storm sewer, drain eld, adjacent stream or pond, etc.). Most local codes forbid the use of sanitary

sewer for disposal. Consult your local building and zoning department to assure compliance in your area. The pump should be sized to handle the home’s domestic water load (typically 5-9 gpm [23-41 l/m]) plus the ow rate required for the heat pump. Pump sizing and expansion tank must be chosen as complimentary items. For example, an expansion tank that is too small can causing premature pump failure due to short cycling. Variable speed pumping applications should be considered for the inherent energy savings and smaller expansion tank requirements.

Water Control Valve

Always maintain water pressure in the heat exchanger by placing the water control valve(s) on the discharge line to prevent mineral precipitation during the off-cycle. Pilot operated slow closing valves are recommended to reduce water hammer. If water hammer persists, a mini-expansion tank can be mounted on the piping to help absorb the excess hammer shock. Insure that the total ‘VA’ draw of the valve can be supplied by the unit transformer. For instance, a slow closing valve can draw up to 35VA. This can overload smaller 40 or 50 VA transformers depending on the other controls in the circuit. A typical pilot operated solenoid valve draws approximately 15VA. Note the special wiring diagrams later in this manual for slow closing valves.

Flow Regulation

Flow regulation can be accomplished by two methods. One method of ow regulation involves simply adjusting the ball valve or water control valve on the discharge line. Measure the pressure drop through the unit heat exchanger, and determine ow rate from tables located later in this manual. Since the pressure is constantly varying, two pressure gauges may be needed. Adjust the valve until the desired ow of 1.5 to 2 gpm per ton [2.0 to 2.6 l/m per kW] is achieved. A second method of ow control requires a ow control device mounted on the outlet of the water control valve. The device is typically a brass tting with an orice of rubber or plastic material that is designed to allow a specied ow rate. On occasion, ow control devices may produce velocity noise that can be reduced by applying some back pressure from the ball valve located on the discharge line. Slightly closing the valve will spread the pressure drop over both devices, lessening the velocity noise. NOTE: When EWT is below 50°F [10°C], a

minimum of 2 gpm per ton (2.6 l/m per kW) is required.

Water Coil Low Temperature Limit Setting

For all open loop systems the 30°F [-1.1°C] FP1 setting (factory setting-water) should be used to avoid freeze damage to the unit. See “Low Water Temperature Cutout Selection” in this manual for details on the low limit setting.

Ground-Water Heat Pump Applications

� CAUTION! �

CAUTION! Many units are installed with a factory or eld supplied manual or electric shut-off valve. DAMAGE WILL OCCUR if shut-off valve is closed during unit operation. A high pressure switch must be installed on the heat pump side of any eld provided shut-off valves and connected to the heat pump controls in series with the built-in refrigerant circuit high pressure switch to disable compressor operation if water pressure exceeds pressure switch setting. The eld installed high pressure switch shall have a cut-out pressure of 300 psig and a cut-in pressure of 250 psig. This pressure switch can be ordered with a 1/4” internal are connection as part number 39B0005N02.

Load Side Plumbing Installation

50YER Unit Load Plumbing

The applications are too varied to describe in this document. However, some basic guidelines will be presented. Much of the discussions on water loop applications would be valid for the load plumbing discussion as well. All plumbing should conform to local codes with the following considerations:

Wide temperature variation applications such as heating/ cooling coils:

- Employ piping materials that are rated for the maximum temperature and pressure combination. This excludes PVC for most heating applications.

- Insure that load water ow in high temperature heating applications is at least 3 gpm per ton [3.9 l/m per kW] to improve performance and reduce nuisance high pressure faults.

- DO NOT employ plastic to metal threaded joints

- Utilize a pressure tank and air separator vent system to equalize pressure and remove air.

Swimming Pool Hot Tub Applications:

- Load coax should be isolated with secondary heat exchanger constructed of anti-corrosion material in all chlorine/bromine uid applications.

Potable Water Applications:

- Load coax material should always be vented double walled for use in potable water systems.

- Insure load water ow in high temperature heating applications is at least 3 gpm per ton to improve performance and reduce nuissance to high pressure faults.

NOTE: It is strongly recommended that all piping connections, both internal and external to the unit, be pressure tested by an appropriate method prior to any nishing of the interior space or before access to all connections is limited. Test pressure may not exceed the maximum allowable pressure for the unit and all components within the water system. The heat pump manufacturer will not be responsible or liable for damages from water leaks due to inadequate or lack of a pressurized leak test, or damages caused by exceeding the maximum pressure rating during installation.

Hot Water Generator

The HWG (Hot Water Generator) or desuperheater option provides considerable operating cost savings by utilizing excess heat energy from the heat pump to help satisfy domestic hot water requirements. The HWG is active throughout the year, providing virtually free hot water when the heat pump operates in the cooling mode or hot water at the COP of the heat pump during operation in the heating mode.

Heat pumps equipped with the HWG option include a builtin water to refrigerant heat exchanger that eliminates the need to tie into the heat pump refrigerant circuit in the eld. The control circuit and pump are also built in for residential equipment. Figure 3 shows a typical example of HWG water piping connections on a unit with built-in pump. This piping layout minimizes scaling potential.

Electric water heaters are recommended. If a gas, propane, or oil water heater is used, a second preheat tank should be considered (Figure 4). Also, if the electric water heater has only a single center element, the dual tank system is recommended to insure a usable entering water temperature for the HWG.

Figure 3: Typical HWG Installation

Typically a single tank of at least 52 gallons (235 liters) is used to limit installation costs and space. However, a dual tank, as shown in Figure 4, is the most efcient system, providing the maximum storage and temperate source water to the HWG.

It is always advisable to use water softening equipment on domestic water systems to reduce the scaling potential and lengthen equipment life. In extreme water conditions, it may be necessary to avoid the use of the HWG option since the potential cost of frequent maintenance may offset or exceed any savings.

HFC-410A systems inherently have a lower hot gas temperature than R-22 systems because the equipment is more efcient (i.e. less waste heat is available). It is possible that energy could be transferred from the water heater to the hot gas line instead of from the hot gas line to the water heater during certain times of the year. To prevent this from occurring, a temperature switch will deactivate the pump at those conditions that typically occur in the cooling mode with low entering water temperatures.

Hot Water Generator

Installation

The HWG high limit temperature switch is set at 125°F [52°C] and is located on the HWG heat exchanger “Water In” line. If the HWG is connected incorrectly or if circulation is reversed, the aquastat will sense leaving water temperature and prevent HWG operation. UNDER NO CIRCUMSTANCES SHOULD THE LIMIT BE DISCONNECTED OR REMOVED! Full load conditions could drive hot water tank temperatures far above safe temperature levels if the aquastat has been disconnected or removed.

The heat pump, water piping, pump, and hot water tank should be located where the ambient temperature is not subject to freezing. Keep water piping lengths at a minimum. DO NOT use a one way length greater than 50 ft. [15 m].

All installations must be in accordance with local codes. The installer is responsible for knowing the local requirements, and for performing the installation accordingly. DO NOT connect the pump wiring until “Initial Start-Up” section, below. Powering the pump before all installation steps are completed may damage the pump.

Water Tank Preparation

1. Turn off power or fuel supply to the hot water tank.

2. Connect a hose to the drain valve on the water tank.

3. Shut off the cold water supply to the water tank.

4. Open the drain valve and open the pressure relief valve

or a hot water faucet to drain tank.

5. When using an existing tank, it should be ushed with

cold water after it is drained until the water leaving the drain hose is clear and free of sediment.

6. Close all valves and remove the drain hose.

7. Install HWG water piping.

4. Inspect all work for leaks.

Before restoring power or fuel supply to the water heater, adjust the temperature setting on the tank thermostat(s) to insure maximum utilization of the heat available from the refrigeration system and conserve the most energy. On tanks with both upper and lower elements and thermostats, the lower element should be turned down to 100°F [38°C] or the lowest setting; the upper element should be adjusted to 120-130°F [49-54°C]. Depending upon the specic needs of the customer, you may want to adjust the upper element differently. On tanks with a single thermostat, a preheat tank should be used (Fig 4).

6. Replace access cover(s) and restore power or fuel supply.

Initial Start-Up

1. Make sure all valves in the HWG water circuit are fully open.

2. Turn on the heat pump and allow it to run for 10-15 minutes.

3. Turn the heat pump and heat pump power supply “OFF” and CONNECT POWER TO THE HWG PUMP as shown in the unit wiring diagram. Connect the pump power lead as instructed on the tag attached to the pump wiring.

4. The HWG pump should not run if the compressor is not running.

5. The temperature difference between the water entering and leaving the HWG coil should be approximately 5-10°F [3-6°C].

6. Allow the unit to operate for 20 to 30 minutes to insure that it is functioning properly.

HWG Water Piping

1. Using at least 5/8” [16mm] O.D. copper, route and install the water piping, valves and air vent as shown in Figures 3 or 4. An appropriate method must be employed to purge air from the HWG piping. This may be accomplished by ushing water through the HWG (as In Figures 3 or 4).

2. Insulate all HWG water piping with no less than 3/8” [10mm] wall closed cell insulation.

3. Open both shut off valves and make sure the tank drain valve is closed.

Water Tank Rell

1. Close valve #4. Ensure that the HWG valves (valves #2 and #3) are open. Open the cold water supply (valve #1) to ll the tank through the HWG piping. This will purge air from the HWG piping.

2. Open a hot water faucet to vent air from the system until water ows from faucet; turn off faucet. Open valve #4.

Depress the hot water tank pressure relief valve handle to ensure that there is no air remaining in the tank.

Low Water Temperature Cutout Selection

The CXM control allows the eld selection of low water (or water-antifreeze solution) temperature limit by clipping jumper JW3, which changes the sensing temperature associated with thermistor FP1. Note that the FP1 thermistor is located on the refrigerant line between the coaxial heat exchanger and expansion device (TXV). Therefore, FP1 is sensing refrigerant temperature, not water temperature, which is a better indication of how water ow rate/temperature is affecting the refrigeration circuit.

The factory setting for FP1 is for systems using water (30°F [-1.1°C] refrigerant temperature). In low water temperature (extended range) applications with antifreeze (most ground loops), jumper JW3 should be clipped as shown in Figure 19 to change the setting to 10°F [-12.2°C] refrigerant temperature, a more suitable temperature when using an antifreeze solution. All residential units include water/ refrigerant circuit insulation to prevent internal condensation, which is required when operating with entering water temperatures below 59°F [15°C].

Electrical - Low Voltage Wiring

Accessory Connections

A terminal paralleling the compressor contactor coil has been provided on the CXM control. Terminal “A” is designed to control accessory devices, such as water valves. Note: This terminal should be used only with 24 Volt signals and not line voltage. Terminal “A” is energized with the compressor contactor. See Figure 5 or the specic unit wiring diagram for details.

Figure 5: Accessory Wiring

Water Solenoid Valves

An external solenoid valve(s) should be used on ground water installations to shut off ow to the unit when the compressor is not operating. A slow closing valve may be required to help reduce water hammer. Figure 5 shows typical wiring for a 24VAC external solenoid valve. Figures 6 or 7 illustrate typical slow closing water control valve wiring for Taco 500 series (ClimateMaster P/N AVM…) and Taco SBV series valves. Slow closing valves take approximately 60 seconds to open (very little water will ow before 45 seconds). Once fully open, an end switch allows the compressor to be energized. Only relay or triac based electronic thermostats should be used with slow closing valves. When wired as shown, the slow closing valve will operate properly with the following notations:

1. The valve will remain open during a unit lockout.

2. The valve will draw approximately 25-35 VA through the “Y” signal of the thermostat.

Note: This valve can overheat the anticipator of an

electromechanical thermostat. Therefore, only relay or triac based thermostats should be used.

CXM Controls

CXM Control

For detailed control information, see the CXM Application, Operation and Maintenance (AOM) manual (part #97B0003N12).

Field Selectable Inputs

Test mode: Test mode allows the service technician to check the operation of the control in a timely manner. By momentarily shorting the test terminals, the CXM control enters a 20 minute test mode period in which all time delays are sped up 15 times. Upon entering test mode, the status LED will ash a code representing the last fault. For diagnostic ease at the thermostat, the alarm relay will also cycle during test mode. The alarm relay will cycle on and off similar to the status LED to indicate a code representing the last fault, at the thermostat. Test mode can be exited by shorting the test terminals for 3 seconds. Retry Mode: If the control is attempting a retry of a fault, the status LED will slow ash (slow ash = one ash every 2 seconds) to indicate the control is in the process of retrying.

Field Conguration Options

Note: In the following eld conguration options, jumper wires should be clipped ONLY when power is removed from the CXM control.

Water coil low temperature limit setting: Jumper 3 (JW3-FP1 Low Temp) provides eld selection of temperature limit setting for FP1 of 30°F or 10°F [-1°F or -12°C] (refrigerant temperature).

Not Clipped = 30°F [-1°C]. Clipped = 10°F [-12°C].

Air coil low temperature limit setting: Jumper 2 (JW2FP2 Low Temp) provides eld selection of temperature limit setting for FP2 of 30°F or 10°F [-1°F or -12°C] (refrigerant temperature). Note: This jumper should only be clipped under extenuating circumstances, as recommended by the factory.

Not Clipped = 30°F [-1°C]. Clipped = 10°F [-12°C].

Alarm relay setting: Jumper 1 (JW1-AL2 Dry) provides eld selection of the alarm relay terminal AL2 to be jumpered to 24VAC or to be a dry contact (no connection).

Not Clipped = AL2 connected to R. Clipped = AL2 dry contact (no connection).

DIP Switches

Note: In the following eld conguration options, DIP switches should only be changed when power is removed from the CXM control.

DIP switch 1: Unit Performance Sentinel Disable provides eld selection to disable the UPS feature.

On = Enabled. Off = Disabled.

DIP switch 2: Stage 2 Selection - provides selection of whether compressor has an “on” delay. If set to stage 2, the compressor will have a 3 second delay before energizing. Also, if set for stage 2, the alarm relay will NOT cycle during test mode.

On = Stage 1. Off = Stage 2

DIP switch 3: Not Used. DIP switch 4: DDC Output at EH2 - provides selection for DDC operation. If set to “DDC Output at EH2,” the EH2 terminal will continuously output the last fault code of the controller. If set to “EH2 normal,” EH2 will operate as standard electric heat output.

On = EH2 Normal. Off = DDC Output at EH2.

NOTE: Some CXM controls only have a 2 position DIP switch package. If this is the case, this option can be selected by clipping the jumper which is in position 4 of SW1.

Jumper not clipped = EH2 Normal. Jumper clipped = DDC Output at EH2.

DIP switch 5: Factory Setting - Normal position is “On.” Do not change selection unless instructed to do so by the factory.

Safety Features - CXM Controls

Safety Features – CXM Control

The safety features below are provided to protect the compressor, heat exchangers, wiring and other components from damage caused by operation outside of design conditions.

Anti-short cycle protection: The control features a 5 minute anti-short cycle protection for the compressor. Note: The 5 minute anti-short cycle also occurs at power up. Random start: The control features a random start upon power up of 5-80 seconds. Fault Retry: In Fault Retry mode, the Status LED begins slowly ashing to signal that the control is trying to recover from a fault input. The control will stage off the outputs and then “try again” to satisfy the thermostat input call. Once the thermostat input call is satised, the control will continue on as if no fault occurred. If 3 consecutive faults occur without satisfying the thermostat input call, the control will go into “lockout” mode. The last fault causing the lockout will be stored in memory and can be viewed at the “fault” LED (DXM board) or by going into test mode (CXM board). Note: FP1/FP2 faults are factory set at only one try. Lockout: In lockout mode, the status LED will begin fast ashing. The compressor relay is turned off immediately. Lockout mode can be “soft” reset by turning off the thermostat (or satisfying the call). A “soft” reset keeps the fault in memory but resets the control. A “hard” reset (disconnecting power to the control) resets the control and erases fault memory. Lockout with emergency heat: While in lockout mode, if W becomes active (CXM), emergency heat mode will occur. If DXM is congured for heat pump thermostat type (DIP 1.3), emergency heat will become active if O/ W2 is energized. High pressure switch: When the high pressure switch opens due to high refrigerant pressures, the compressor relay is de-energized immediately since the high pressure switch is in series with the compressor contactor coil. The high pressure fault recognition is immediate (does not delay for 30 continuous seconds before de-energizing the compressor).

High pressure lockout code = 2

Example: 2 quick ashes, 10 sec pause, 2 quick ashes, 10 sec. pause, etc. Low pressure switch: The low pressure switch must be open and remain open for 30 continuous seconds during “on” cycle to be recognized as a low pressure fault. If the low pressure switch is open for 30 seconds prior to compressor power up it will be considered a low pressure (loss of charge) fault. The low pressure switch input is bypassed for the initial 120 seconds of a compressor run cycle.

Low pressure lockout code = 3

Water coil low temperature (FP1): The FP1 thermistor temperature must be below the selected low temperature limit setting for 30 continuous seconds during a compressor run cycle to be recognized as a FP1 fault. The FP1 input is bypassed for the initial 120 seconds of a compressor run cycle. FP1 is set at the factory for one try. Therefore, the control will go into lockout mode once the FP1 fault has occurred.

FP1 lockout code = 4

Air coil low temperature (FP2): The FP2 thermistor temperature must be below the selected low temperature limit setting for 30 continuous seconds during a compressor run cycle to be recognized as a FP2 fault. The FP2 input is bypassed for the initial 120 seconds of a compressor run cycle. FP2 is set at the factory for one try. Therefore, the control will go into lockout mode once the FP2 fault has occurred.

FP2 lockout code = 5

Condensate overow: The condensate overow sensor must sense overow level for 30 continuous seconds to be recognized as a CO fault. Condensate overow will be monitored at all times.

CO lockout code = 6

Over/under voltage shutdown: An over/under voltage condition exists when the control voltage is outside the range of 18VAC to 31.5VAC. Over/under voltage shut down is a self-resetting safety. If the voltage comes back within range for at least 0.5 seconds, normal operation is restored. This is not considered a fault or lockout. If the CXM/DXM is in over/under voltage shutdown for 15 minutes, the alarm relay will close.

Over/under voltage shut down code = 7

Unit Performance Sentinel-UPS (patent pending): The UPS feature indicates when the heat pump is operating inefciently. A UPS condition exists when: a) In heating mode with compressor energized, FP2

is greater than 125°F [52°C] for 30 continuous seconds, or:

b) In cooling mode with compressor energized, FP1

is greater than 125°F [52°C] for 30 continuous seconds, or:

c) In cooling mode with compressor energized, FP2 is

less than 40°F [4.5°C] for 30 continuous seconds.

If a UPS condition occurs, the control will immediately go to UPS warning. The status LED will remain on as if the control is in normal mode. Outputs of the control, excluding LED and alarm relay, will NOT be affected by UPS. The UPS condition cannot occur during a compressor off cycle. During UPS warning,

Page 24

R e v. : 1 J u l y, 2 010

Safety Features

the alarm relay will cycle on and off. The cycle rate will be “on” for 5 seconds, “off” for 25 seconds, “on” for 5 seconds, “off” for 25 seconds, etc.

UPS warning code = 8

Swapped FP1/FP2 thermistors: During test mode, the control monitors to see if the FP1 and FP2 thermistors are in the appropriate places. If the control is in test mode, the control will lockout with code 9 after 30 seconds if: a) The compressor is on in the cooling mode and the

FP1 sensor is colder than the FP2 sensor, or:

b) The compressor is on in the heating mode and the

FP2 sensor is colder than the FP1 sensor.

Swapped FP1/FP2 thermistor code = 9.

ESD (DXM only): The ESD (Emergency Shut Down) mode can be enabled from an external common signal to terminal ESD to shut down the unit. The green status light will ash code 3 when the unit is in ESD mode.

ESD mode = code 3 (green “status” LED)

CXM Controls

Diagnostic Features

The LED on the CXM board advises the technician of the current status of the CXM control. The LED can display either the current CXM mode or the last fault in memory if in test mode. If there is no fault in memory, the LED will ash Code 1 (when in test mode).

CXM Control Start-up Operation

The control will not operate until all inputs and safety controls are checked for normal conditions. The compressor will have a 5 minute anti-short cycle delay at power-up. The rst time after power-up that there is a call for compressor, the compressor will follow a 5 to 80 second random start delay. After the random start delay and anti-short cycle delay, the compressor relay will be energized. On all subsequent compressor calls, the random start delay is omitted.

Unit Commissioning & Operating Conditions

Environment – This unit is designed for indoor

installation only. Do not install in an area subject to freezing or where humidity levels can cause cabinet condensation. Power Supply – A voltage variation of +/- 10% of nameplate utilization voltage is acceptable.

Operation and performance is primarily dependent upon water temperatures, water ow rates and ambient air temperature. This water to water heat pump is capable of operating over a wide temperature range and with ow rates of between 1.5 GPM (.1 l/s) and 3 GPM (.19 l/s) per ton, however usually no more than one of these factors may be at a minimum or maximum level at a time.

The commissioning table indicates water temperatures which are suitable for initial unit commissioning in an environment where the ow rate and water temperature is not yet stable and to avoid nuisance shut down of the units freeze and refrigerant pressure safeties.

The operating table indicates the maximum and minimum ranges of the unit.

For more specic unit performance reference the product catalog, the submittal data sheets or contact your supplier for assistance.

Unit & System Checkout

BEFORE POWERING SYSTEM, please check the following:

� WARNING! �

Verify ALL water controls are open and allow water ow prior to engaging the compressor. Freezing of the coax or water lines can permanently damage the heat pump.

NOTE: The manufacturer strongly recommends all piping connections, both internal and external to the unit, be pressure tested by an appropriate method prior to any nishing of the interior space or before access to all connections is limited. Test pressure may not exceed the maximum allowable pressure for the unit and all components within the water system. The manufacturer will not be responsible or liable for damages from water leaks due to inadequate or lack of a pressurized leak test, or damages caused by exceeding the maximum pressure rating during installation.

UNIT CHECKOUT

q Balancing/Shutoff Valves: Ensure all isolation

valves are open, water control valves wired and open or coax may freeze and burst.

q Line Voltage and Wiring: Ensure Voltage is within

an acceptable range for the unit and wiring and fuses/breakers are properly sized. Low voltage wiring is complete.

q Unit Control Transformer: Ensure transformer has

properly selected control voltage tap. 208-230V units are factory wired for 230 operation unless specied otherwise.

Entering Water: Ensure entering water temperatures are within operating limits of Table 5.

q Low Water Temperature Cutout: Verify low water

temperature cut-out on CXM is properly set.

Water Flow Balancing: Verify inlet and outlet water temperatures on both Load and source are recorded for each heat pump upon startup. This check can eliminate nuisance trip outs and high velocity water ows that can erode heat exchangers.

q Unit Controls: Verify CXM settings are proper and

complete.

SYSTEM CHECKOUT

q System Water Temperature: Check load and

source water temperature for proper range and also verify heating and cooling setpoints for proper operation.

q System pH: System water pH is 6 - 8.5. Proper

pH promotes longevity of hoses and ttings.

System Flushing: Verify all hoses are connected end to end when ushing to ensure debris bypasses unit heat exchanger and water valves etc. Water used in the system must be potable quality initially and clean of dirt, piping slag, and strong chemical cleaning agents. Verify all air is purged from the system. Air in the system can cause poor operation or system corrosion.

q Cooling Tower/Boiler: Check equipment for

proper setpoints and operation.

q Standby Pumps: Verify the standby pump is

properly installed and in operating condition.

q System Controls: Verify system controls function

and operate in the proper sequence.

q Low Water Temperature Cutout: Verify low water

temperature cut-out controls are provided for the outdoor portion of the loop or operating problems will occur.

q System Control Center: Verify control center and

alarm panel for proper setpoints and operation.

Strainers: Verify 20 mesh (841 micron) [0.84mm] strainers are installed in load and source water piping. Conrm maintenance schedule for strainers.

q Miscellaneous: Note any questionable aspects of

the installation.

� WARNING! �

To avoid equipment damage, DO NOT leave system lled in a building without heat during the winter unless antifreeze is added to system water. Condenser coils never fully drain by themselves and will freeze unless winterized with antifreeze.

Unit Start Up Procedure

� WARNING! �

When the disconnect switch is closed, high voltage is present in some areas of the electrical panel. Exercise caution when working with energized equipment.

1. Adjust all valves to their full open position. Turn on the line power to all heat pump units.

2. Operate each unit in the cooling cycle.

3. Operate each heat pump in the heating cycle immediately after checking cooling cycle operation. A time delay will prevent the compressor from re-starting for approximately ve (5) minutes.

4. Establish a permanent operating record by logging the unit operating conditions at initial start-up for each unit.

5. If a unit fails to operate, conduct the following checks: a. Check the voltage and current. They should

comply with the electrical specications described on the unit nameplate.

b. Look for wiring errors. Check for loose terminal

screws where wire connections have been made on both the line and low-voltage terminal boards.

c. Check the supply and return piping. They must

be properly connected to the inlet and outlet connections on the unit.

d. If the checks described above fail to reveal

the problem and the unit still will not operate, contact a trained service technician to ensure proper diagnosis and repair of the equipment.

Preventative Maintenance

Water Coil Maintenance

(Direct ground water applications only) - If the system is installed in an area with a known high mineral content (125 P.P.M. or greater) in the water, it is best to establish a periodic maintenance schedule with the owner so the coil can be checked regularly. Consult the well water applications section of this manual for a more detailed water coil material selection. Should periodic coil cleaning be necessary, use standard coil cleaning procedures, which are compatible with the heat exchanger material and copper water lines. Generally, the more water owing through the unit, the less chance for scaling. Therefore, 1.5 gpm per ton [2.0 l/m per kW] is recommended as a minimum ow. Minimum ow rate for entering water temperatures below 50°F [10°C] is 2.0 gpm per ton [2.6 l/m per kW].

Water Coil Maintenance

(All other water loop applications) Generally water coil maintenance is not needed for closed loop systems. However, if the piping is known to have high dirt or debris content, it is best to establish a periodic maintenance schedule with the owner so the water coil can be checked regularly. Dirty installations are typically the result of deterioration of iron or galvanized piping or components in the system. Open cooling towers requiring heavy chemical treatment and mineral buildup through water use can also contribute to higher maintenance. Should periodic coil cleaning be necessary, use standard coil cleaning procedures, which are compatible with both the heat exchanger material and copper water lines. Generally, the more water owing through the unit, the less chance for scaling. However, ow rates over 3 gpm per ton (3.9 l/m per kW) can produce water (or debris) velocities that can erode the heat exchanger wall and ultimately produce leaks.

Cabinet

Do not allow water to stay in contact with the cabinet for long periods of time to prevent corrosion of the cabinet sheet metal. Generally cabinets are set up from the oor a few inches for prevention. The cabinet can be cleaned using a mild detergent.

Refrigerant System To maintain sealed circuit integrity, do not install service gauges unless unit operation appears abnormal. Reference the operating chart for pressure and temperatures. Verify that air and water ow rates are at proper levels before servicing

the refrigerant circuit.

If the refrigerant circuit is opened for any reason, a new liquid line lter-drier must be installed.

Hot Water Generator Coils

See water coil maintenance for ground water units. If the potable water is hard or not chemically softened, the high temperatures of the desuperheater will tend to scale even quicker than the water coil and may need more frequent inspections. In areas with extremely hard water, a HWG is

not recommended.

Compressors

Conduct annual amperage checks to ensure amp draw is no more than 10% greater than that indicated by serial plate data.
