APPLICATION AND LOCATION

GENERAL

Units are shipped completely assembled and internally wired, requiring only duct connections, thermostatwiring, 230-208 volt AC power wiring, and water piping. The equipment covered in this manual is to beinstalled by trained, experienced service and installation technicians. Any heat pump is more critical of properrefrigerant charge and an adequate duct system than a cooling only air conditioning unit.

These instructions and any instructions packaged with any separate equipment required to make up the entireheat pump system should be carefully read before beginning the installation. Note particularly any tags and/orlabels attached to the equipment.

While these instructions are intended as a general recommended guide, they do not in any way supersede anynational and/or local codes. Authorities having jurisdiction should be consulted before the installation is made.

SHIPPING DAMAGE

Upon receipt of the equipment, the carton should be checked for external signs of shipping damage. Ifdamage is found, the receiving party must contact the last carrier immediately, preferably in writing, requestinginspection by the carrier's agent.

APPLICATION

Capacity of the unit for a proposed installation should be based on heat loss calculations made in accordancewith methods of the Air Conditioning Contractors of America, formerly National Warm Air Heating and AirConditioning Association. The air duct system should be sized and installed in accordance with Standards ofthe National Fire Protection Association for the Installation of Air Conditioning and Ventilating Systems of Otherthan Residence Type NFPA No. 90A, and Residence Type Warm Air Heating and Air Conditioning Systems,NFPA No. 90B.

LOCATION

The unit may be installed in a basement, closet or utility room provided adequate service access is insured.Ideally, three sides of the unit should have a minimum access clearance of two feet but the unit can beadequately serviced if two or only one side has a minimum two feet of clearance. The unit should be locatedin the conditioned space to prevent freezing of the water lines.

Clearance to combustible materials is 0 inches for the heat pump. If an optional duct heater is installed, followthe instructions packed with the duct heater for specifications regarding clearance to combustible material.

Before setting the unit, consider ease of piping, drain and electrical connections for the unit. Also, for unitswhich will be used with a field installed heat recovery unit, consider the proximity of the unit to the water heateror storage tank. Place the unit on a solid base, preferably concrete, to minimize undesirable noise andvibration. DO NOT elevate the base pan on rubber or cork vibration eliminator pads as this will permit the unitbase to act like a drum, transmitting objectionable noise.

DUCT WORK

If the unit is to be installed in a closet or utility room which does not have a floor drain, a secondary drain panunder the entire unit is highly recommended.

DO NOT install the unit in such a way that a direct path exists between any return grille and the unit. Rather,insure that the air entering the return grille will make at least one turn before entering the unit air coil. This willreduce possible objectionable compressor and air noise from entering the occupied space.

Design the duct work according to methods given by the Air Conditioning Contractors of America. When ductruns through unconditioned spaces, it should be insulated with vapor barrier. It is recommended that flexibleconnections be used to connect the duct work to the unit in order to keep the noise transmission to aminimum.


FILTER

This unit must not be operated without a filter. It comes equipped with a disposable filter which should bechecked often and replaced if dirty. Insufficient air flow due to undersized duct systems or dirty filters canresult in nuisance tripping of the high or low pressure control. Refer to Table 1 for correct air flow and staticpressure requirements. See Figure 1.

FIGURE 1FILTER REMOVAL

wpv0.tif

CONDENSATE DRAIN

Determine where the drain line will run. This drain line contains cold water and must be insulated to avoiddroplets of water from condensing on the pipe and dropping on finished floors or the ceiling under the unit. Atrap MUST BE installed in the drain line and the trap filled with water prior to start up. The use of plugged teesin place of elbows to facilitate cleaning is highly recommended.

Drain lines must be installed according to local plumbing codes. It is not recommended that any condensatedrain line be connected to a sewer main. The drain line enters the unit through the water access panel, seeFigure 2, and connects to the FPT coupling under the condensate drain pan.

PIPING ACCESS TO THE UNIT

Water piping to and from the unit enters the unit casing through the water access panel. Piping connectionsare made directly to the heat exchanger coil and are 3/4" or 1" FPT. The access panel can be installed on thefront of the unit (as received) or on the right side of the unit. It is highly recommended that the piping from thewater coil to the outside of the casing be installed while the unit is completely accessible and before it is finallyset in position. Two 1 3/4" inch plastic bushings are provided (packed with unit installation instructions) toprotect piping from sheet metal edges of access panel. See Figure 2.

MIS-380

WIRING

All electrical connections are made through the top of the unit. High voltage connections are made with wirenuts to the factory-provided pigtail leads in the junction box. Low voltage connections are made to the terminalstrip mounted on the top of the unit. Refer to the wiring diagram for connecting the terminals.

MAIN POWER

Refer to the unit serial plate for wire sizing information and correct protection size. Each unit is marked with a"Minimum Circuit Ampacity." This means that field wiring connections must be sized to carry that amount ofcurrent. Each unit and/or wiring diagram is also marked "Use Copper Conductors Only," meaning the leadsprovided are not suitable for aluminum wiring. Refer to the National Electric Code for complete current-carrying capacity data on the various grades of wiring material.

The unit rating plate lists "Maximum Overcurrent Protective Device" that is to be used with the equipment.This device may be a time delay fuse or HACR type circuit breaker. The correct size overcurrent protectivedevice must be used to provide for proper circuit protection and to avoid nuisance trips due to the momentaryhigh starting current of the compressor motor.

THERMOSTAT LOW VOLTAGE WIRING

A 24 volt terminal strip is mounted on top of the unit with an optional terminal board cover included with the unitinstallation instructions. See Figure 3. Two types of thermostats are available: 1) Single stage heat, singlestage cool to operate the heat pump alone without backup duct style electric heaters. This thermostat isequipped with a signal light to indicate when the unit is "locked out" because of the low temperature or highpressure control. Refer to the wiring diagram 4091-810 for correct connection of the terminals. 2) Two stageheat, single cool to operate the heat pump or duct heaters on heating or the heat pump on cooling. Thisthermostat is also equipped with a signal light to indicate when the unit is "locked out" because of operation ofthe low temperature or high pressure control. In addition, a second signal light tells when the unit has beenplaced in Emergency Heat. Refer to the wiring diagram 4091-811, and to the wiring diagram packed with theduct heater for correct connection of the low voltage terminals.

FIGURE 4DUCT HEATER

The following is a verbal description of the proper procedure for connecting the low voltage hookups for theduct heater. (Refer to wiring diagram 4091-811).

1. Black wire from duct heater to C on the 24 volt terminal block.

2. Green wire from duct heater to green wire from thermostat. These wires must be wire nutted and isolatedfrom the terminal block. Failure to do so will result in improper heater operation.

3. Connect green with tracer from heater to the G terminal on the 24 volt terminal block.

4. Connect the white wire from the heater to W2 on 24 volt terminal block.A. For the 15 and 20 KW duct heaters, connect the white and white with black tracer wires to W2.

ACCESSORIES

ADD-ON DPM26A PUMP MODULE KITNOTE: This section applies only if a DPM26A Pump Module is added. Refer to DPM26A instructions for complete

installation details.

GENERALThis high efficiency water source heat pump series was designed with a refrigerant to water heat exchanger commonlyknow as a desuperheater coil factory-installed for ease in installing optional DPMA pump module kit. The addition ofthis optional kit allows for heat recovery for hot water heating when connected to a home water heater. The amount ofannual hot water supplied and thus additional energy cost savings will depend on the amount of hot water usage and thenumber of hours the heat pump operates. This pump kit is suitable for potable water.

INSTALLATION1. Follow all local, state, and national codes applicable to the installation of the pump module kit.

2. Follow the installation instructions received with the DPM26A pump module kit.

3. Connect the water lines between the unit, pump module kit, and the water heater.

CLOSED LOOP(Earth Coupled Ground Loop Applications)

NOTE: Low temperature thermostat must be reset from factory setting to 15º for closedloop applications.

This unit is designed to work on earth coupled ground loop systems, however, these systems operate atentering water (without antifreeze) temperature well below the temperature normally experienced in water wellsystem.

For information on earth coupled loop design, piping connections to heat pump and installation refer to manual2100-099, "Earth Coupled Loop System Design Manual," available from your distributor.

THE CIRCULATION SYSTEM DESIGN

Equipment room piping design is based on years of experience with earth coupled heat pump systems. Thedesign eliminates most causes of system failure.

Surprisingly, the heat pump itself is rarely the cause. Most problems occur because designers and installersforget that a closed loop earth coupled heat pump system is NOT like a household plumbing system.

Most household water systems have more than enough water pressure either from the well pump or themunicipal water system to overcome the pressure or head loss in 1/2 inch or 3/4 inch household plumbing. Aclosed loop earth coupled heat pump system, however, is separated from the pressure of the householdsupply and relies on a small, low wattage pump to circulate the water and antifreeze solution through the earthcoupling, heat pump and equipment room components.

The small circulator keeps the operating costs of the system to a minimum. However, the performance of thecirculator MUST be closely matched with the pressure or head loss of the entire system in order to provide therequired flow through the heat pump. Insufficient flow through the heat exchanger is one of the most commoncauses of system failure. Proper system piping design and circulator selection will eliminate this problem.

Bard supplies a worksheet to simplify head loss calculations and circulator selection. Refer to "CirculatingPump Worksheet" section in manual 2100-099.

Two general methods are used to pipe the water circuit in the equipment room. The first and easiest to use isto install a pump module. This module comes complete with connecting hose and heat pump adaptersavailable from Bard. A second method is to "site build" the piping at the installation.

To move the transfer fluid (water or antifreeze and water solution) through the earth loop system and the watersource heat pump, some type of circulation system is required. Design of circulation system must includeprovisions for the following. See Figure 6.

1. Selection of a circulation pump or pumps for total system.

2. Providing air bleed off before start-up running.

3. Providing for flow monitoring.

4. Positive pressure control and limiting.

5. Antifreeze charging capability.

NOTE: The expansion and contraction of earth loop piping may cause a 50 to 60 psig water pressure chargein system between summer to winter.


The components for a circulation system are as follows: Refer to Figure 6.

1. Circulating pump systems are engineered for each individual system to provide the correct water flowand overcome the friction loss of the system piping. Isolation flanges or ball valves are used to insulatepump from system piping. You need to be able to remove the pump from piping without losing thetransfer fluid for repairs if ever required.

Determining pressure drop and selecting a circulation pump or pumps. It is very important inselecting the circulating pump that a very accurate pressure drop calculation be made because finalpressure drop at the selected pump must pump against will to determine the actual flow rate (GPM)that is delivered to the water source heat pump, the pumping cost and efficiency of the entire system.

2. Ball valve and flange

3. Barb X MIP brass adapter

4. Brass test plugs--in order to start up and troubleshoot a closed loop system properly, water in and waterout temperatures at the heat pump must be monitored. A test plug is installed on one leg of eachconnection line. A probe thermostat can be temporarily inserted, the temperature monitored and thethermometer removed. Use one thermometer to monitor these temperatures. Using two differentthermometers to measure the temperature differential can introduce large measurement errors. Theyare also used to measure pressure drop to determine coil flow rate.

5. Bard X insert brass adapter

6. Two boiler drains are located on both sides of the circulator for final filling, air purging and antifreezeaddition.

The top drain should be the highest point in the equipment room piping. This will help purge air out of thesystem during final filling at start up.

7. PE or PB pipe to fit transition

8. One inch reinforced flexible hose

9. 90º street ell (brass)

10. Flow meter (Bard part No. 8603-017)--or equivalent side to monitor water flow is recommended.

HEAT PUMP CONNECTIONS WITHOUT PUMP KIT

The units have various female connections inside on water coil. To keep losses small, all piping andcomponents in the heat pump should be one inch copper or plastic. The transition to one inch pipe should bemade at the exterior of the heat pump if 3/4 inch piping is used in small heat pump models.

Be sure to use a backup wrench when installing the adapters to the heat pump.

PIPING CONNECTIONS

Up to 12 feet of reinforced flexible hose is used. Cut hoses to the desired lengths and install with as fewbends as possible. Close bends increase pipe head loss so any bends should be as wide as possible. Usethe clamps to secure hoses in position.

SYSTEM START UP PROCEDURE

1. Be sure main power to the unit is OFF at disconnect.

2. Set thermostat system switch to OFF, fan switch to AUTO.

3. Move main power disconnect to ON. Except as required for safety while servicing, DO NOTOPEN THE UNIT DISCONNECT SWITCH.

4. Check system air flow for obstructions.

A. Move thermostat fan switch to ON. Blower runs.B. Be sure all registers and grilles are open.

C. Move thermostat fan switch to AUTO. Blower should stop.

5. Flush, fill and pressurize the closed loop system as outlined in manual 2100-099.

6. Fully open the manual inlet and outlet valves. Start the loop pump module circulator(s) and check forproper operation. If circulator(s) are not operating, turn off power and diagnose the problem.

7. Check fluid flow using a direct reading flow meter or a single water pressure gauge, measure thepressure drop at the pressure-temperature plugs across the water coil. Compare the measurementwith flow versus pressure drop table to determine the actual flow rate. If the flow rate is too low,recheck the selection of the loop pump module model for sufficient capacity. If the module selection iscorrect, there is probably trapped air or a restriction in the piping circuit.

8. Start the unit in cooling mode. By moving the thermostat switch to cool, fan should be set for AUTO.

9. Check the system refrigerant pressures against the cooling refrigerant pressure table in the installationmanual for rated water flow and entering water temperatures. If the refrigerant pressures do notmatch, check for air flow problem then refrigeration system problem.

10. Switch the unit to the heating mode. By moving the thermostat switch to heat, fan should be set forAUTO.

11. Check the refrigerant system pressures against the heating refrigerant pressure table in installationmanual. Once again, if they do not match, check for air flow problems and then refrigeration systemproblems.

NOTE: If a charge problem is determined (high or low):

A. Check for possible refrigerant leaks.

B. Recover all remaining refrigerant from unit and repair leak.

C. Evacuate unit down to 29 inches of vacuum.

D. Recharge the unit with refrigerant by weight. This is the only way to insure a proper charge.


OPEN LOOP (Well System Applications)

NOTE: Low temperature thermostat factory set to 25º for open loop applications.

It is very important that an adequate supply of clean, noncorrosive water at the proper pressure be providedbefore the installation is made. Insufficient water, in the heating mode for example, will cause the lowtemperature control to trip, shutting down the heat pump. In assessing the capacity of the water system, it isadvisable that the complete water system be evaluated to prevent possible lack of water or water pressure atvarious household fixtures whenever the heat pump turns on. All plumbing to and from the unit is to beinstalled in accordance with local plumbing codes. The use of plastic pipe, where permissible, isrecommended to prevent electrolytic corrosion of the water pipe. Because of the relatively cold temperaturesencountered with well water, it is strongly recommended that the water lines connecting the unit be insulated toprevent water droplets from condensing on the pipe surface.

Refer to piping, Figure 14. Slow closing Solenoid Valve (6) with a 24V coil provides on/off control of the waterflow to the unit. Refer to the wiring diagram for correct hookup of the valve solenoid coil.

Constant Flow Valve (7) provides correct flow of water to the unit regardless of variations in water pressure.Observe the water flow direction indicated by the arrow on the side of the valve body. Following is a tableshowing which valve is to be installed with which heat pump.

Strainer (5) installed upstream of constant flow valve (7) to collect foreign material which would clog the flowvalve orifice.

Figure 14 shows the use of shut-off valves (9) and (11), on the in and out water lines to permit isolation of theunit from the plumbing system should future service work require this. Globe valves should not be used asshut-off valves because of the excessive pressure drop inherent in the valve design. Instead use gate or ballvalves as shut-offs so as to minimize pressure drop.

Drain cocks (8) and (10) and tees have been included to permit acid cleaning the refrigerant-to-water coilshould such cleaning be required. See WATER CORROSION.

Drain cock (12) provides access to the system to check water flow through the constant flow valve to insureadequate water flow through the unit. A water meter 1-10 GPM (8603-013) is used to check the water flowrate.

TABLE 5CONSTANT FLOW VALVES


WELL PUMP SIZING

Strictly speaking, sizing the well pump is the responsibility of the well drilling contractor. It is important,however, that the HVAC contractor be familiar with the factors that determine what size pump will be required.Rule of thumb estimates will invariably lead to under or oversized well pumps. Undersizing the pump will resultin inadequate water to the whole plumbing system but with especially bad results to the heat pump--NO HEAT/NO COOL calls will result. Oversized pumps will short cycle and could cause premature pump motor or switchfailures.

The well pump must be capable of supplying enough water and at an adequate pressure to meet competingdemands of water fixtures. The well pump must be sized in such a way that three requirements are met:

1. Adequate flow rate in GPM

2. Adequate pressure at the fixture.

3. Able to meet the above from the depth of the well-feet of lift.

The pressure requirements put on the pump are directly affected by the diameter of pipe being used, as wellas, by the water flow rate through the pipe. The worksheet included in manual 2100-078 should guaranteethat the well pump has enough capacity. It should also ensure that the piping is not undersized which wouldcreate too much pressure due to friction loss. High pressure losses due to undersized pipe will reduceefficiency and require larger pumps and could also create water noise problems.

SYSTEM START UP PROCEDURE

1. Be sure main power to the unit is OFF at disconnect.

2. Set thermostat system switch to OFF, fan switch to AUTO.

3. Move main power disconnect to ON. Except as required for safety while servicing -- DO NOT OPENTHE UNIT DISCONNECT SWITCH.

9. Switch the unit to the heat mode. By moving the thermostat switch to heat, fan should be set for AUTO.A. Check to see the solenoid valve opened again.

10. Check the refrigerant system pressures against the heating refrigerant pressure table in installationmanual. Once again, if they do not match, check for air flow problems and then refrigeration systemproblems.

NOTE: If a charge problem is determined (high or low):

A. Check for possible refrigerant loss.B. Discharge all remaining refrigerant from unit.

C. Evacuate unit down to 29 inches of vacuum.

D. Recharge the unit with refrigerant by weight. This is the only way to insure a proper charge.

WATER CORROSION

Two concerns will immediately come to light when considering a water source heat pump, whether for groundwater or for a closed loop application: Will there be enough water? And, how will the water quality affect thesystem?

Water quantity is an important consideration and one which is easily determined. The well driller must performa pump down test on the well according to methods described by the National Well Water Association. Thistest, if performed correctly, will provide information on the rate of flow and on the capacity of the well. It isimportant to consider the overall capacity of the well when thinking about a water source heat pump becausethe heat pump may be required to run for extended periods of time.

The second concern, about water quality, is equally important. Generally speaking, if the water is not offensivefor drinking purposes, it should pose no problem for the heat pump. The well driller or local water softeningcompany can perform tests which will determine the chemical properties of the well water.

Water quality problems will show up in the heat pump in one or more of the following ways:

1. Decrease in water flow through the unit.

2. Decreased heat transfer of the water coil (entering to leaving water temperature difference is less).


There are four main water quality problems associated with ground water. These are:

1. Biological Growth. This is the growth of microscopic organisms in the water and will show up as a slimydeposit through out the water system. Shock treatment of the well is usually required and this is bestleft up to the well driller. The treatment consists of injecting chlorine into the well casing and flushingthe system until all growth is removed.

2. Suspended Particles in the Water. Filtering will usually remove most suspended particles (fine sand,small gravel) from the water. The problem with suspended particles in the water is that it will erodemetal parts, pumps, heat transfer coils, etc. So long as the filter is cleaned and periodicallymaintained, suspended particles should pose no serious problem. Consult with your well driller.

3. Corrosion of Metal. Corrosion of metal parts results from either highly corrosive water (acid water,generally not the case with ground water) or galvanic reaction between dissimilar metals in thepresence of water. By using plastic plumbing or dielectric unions galvanic reaction is eliminated. Theuse of corrosion resistant materials (such as the Cupro Nickel coil) through the water system will reducecorrosion problems significantly.

4. Scale Formation. Of all the water problems, the formation of scale by ground water is by far the mostcommon. Usually this scale is due to the formation of calcium carbonate by magnesium carbonate orcalcium sulfate may also be present. Carbon dioxide gas (CO2), the carbonate of calcium andmagnesium carbonate, is very soluble in water. It will remain dissolved in the water until some outsidefactor upsets the balance. This outside influence may be a large change in water temperature orpressure. When this happens, enough carbon dioxide gas combines with dissolved calcium ormagnesium in the water and falls out of solution until a new balance is reached. The change intemperature that this heat pump produces is usually not high enough to cause the dissolved gas to fallout of solution. Likewise, if pressure drops are kept to a reasonable level, no precipitation of carbondioxide should occur.

REMEDIES OF WATER PROBLEMS

Water Treatment. Water treatment can usually be economically justified for closed loop systems. However,because of the large amounts of water involved with a ground water heat pump, water treatment is generallytoo expensive.

Acid Cleaning the Water Coil or Heat Pump Recovery Unit. If scaling of the coil is strongly suspected, the coilcan be cleaned up with a solution of Phosphoric Acid (food grade acid). Follow the manufacturer's directionsfor mixing, use, etc. Refer to the "Cleaning Water Coil," Figure 15. The acid solution can be introduced intothe heat pump coil through the hose bib (part 8 of Figure 15). Be sure the isolation valves (parts 9 and 11 ofFigure 15) are closed to prevent contamination of the rest of the system by the coil. The acid should bepumped from a bucket into the hose bib (part 8 of Figure 15) and returned to the bucket through the otherhose bib (part 10 of Figure 15). Follow the manufacturer's directions for the product used as to how long thesolution is to be circulated, but it is usually circulated for a period of several hours.

LAKE AND POND INSTALLATIONS

Lakes and ponds can provide a low cost source of water for heating and cooling with a ground water heatpump. Direct usage of the water without some filtration is not recommended as algae and turbid water canfoul the water to freon heat exchanger. Instead, there have been very good results using a dry well dug next tothe water line or edge. Normal procedure in installing a dry well is to backhoe a 15 to 20 foot hole adjacent tothe body of water (set backhoe as close to the water's edge as possible). Once excavated, a perforatedplastic casing should be installed with gravel backfill placed around the casing. The gravel bed should provideadequate filtration of the water to allow good performance of the ground water heat pump. Refer to Figure 16.

The following is a list of recommendations to following when installing this type of system:

A. A lake or pond should be at least 1 acre (40,000 square feet) in surface area for each 50,000 BTUs ofground water heat pump capacity or have 2 times the cubic feet size of the dwelling that you are tryingto heat (includes basement if heated).

B. The average water depth should be at least 5 feet and there should be an area where the water depthis at least 12 to 15 feet deep.

C. If possible, use a submersible pump suspended in the dry well casing. Jet pumps and other types ofsuction pumps normally consume more electrical energy than similarly sized submersible pumps. Pipethe unit the same as a water well system.

D. Size the pump to provide necessary GPM for the ground water heat pump. A 12 GPM or greater waterflow rate is required on all modes when used on this type system.

E. A pressure tank should be installed in dwelling to be heated adjacent to the ground water heat pump.A pressure switch should be installed at the tank for pump control.

F. All plumbing should be carefully sized to compensate for friction losses, etc., particularly if the pond orlake is over 200 feet from the dwelling to be heated or cooled.

G. Keep all water lines below low water level and below the frost line.

H. Most installers use 4 inch field tile (rigid plastic or corrugated) for water return to the lake or pond.

I. The drain line discharge should be located at least 100 feet from the dry well location.

J. The drain line should be installed with a slope of 2 inches per 10 feet of run to provide completedrainage of the line when the ground water heat pump is not operating. This gradient should also helpprevent freezing of the discharge where the pipe terminates above the frost line.

K. Locate the discharge high enough above high water level so the water will not back up and freezeinside the drain pipe.

L. Where the local conditions prevent the use of a gravity drainage system to a lake or pond, you caninstead run standard plastic piping out into the pond below the frost and low water level.

For complete information on water well systems and lake and pond applications, refer to Manual 2100-078available from your distributor.

WARNINGThin ice may result in the vicinity of the discharge line.

1. COOLING WITH OR WITHOUT DUCT HEATERS

Whenever the system lever is moved to COOL, thermostat system switch completes a circuit R to O,energizing the reversing valve solenoid. On a call for cooling, the cooling bulb completes a circuit fromR to G, energizing the blower relay coil. The blower relay contacts complete a 230 volt circuit to theblower motor and the blower operates. R to Y circuit is completed at the same time as the fan circuitand current flows from Y to terminal 4 at the lockout relay. Terminal 4 of the lockout relay provides twopaths for current flow.

A. Through the lockout relay coil which offers the resistance of the lockout relay coil.

B. Through the normally closed contacts of the lockout relay to terminal 5 of the lockout relay and thenthrough the high and low pressure switches to the compressor contactor coil.

If the high pressure and low temperature switches remain closed (refrigerant pressure and temperatureremains normal), the path of least resistance is through these safety controls to the compressorcontactor coil. The contacts of the compressor contactor complete a 230 volt circuit to the compressorand the compressor runs. If discharge pressure reaches the set point of the high pressure control, thenormally closed contacts of the high pressure control open and current no longer flows to thecompressor contact coil--the coil drops out. Current now can take the path of least resistance throughthe lockout relay coil, energizing the lockout relay coil and opening terminals 4 and 5 of the lockoutrelay. The lockout relay will remain energized as long as a circuit is completed between R and Y at thethermostat. In the meantime, since the compressor is operating, refrigerant pressure will equalize andthe high pressure switch will automatically reset. However, the circuit to the compressor contact will notbe complete until the lockout relay is de-energized by moving the thermostat system switch to OFF,breaking the circuit from R to Y dropping out the lockout relay coil and permitting terminals 4 and 5 tomake. When the high pressure switch closes, a circuit is complete to L at the thermostat, energizingthe signal light to indicate a malfunction. When the system switch is moved from OFF to COOL, thecycle is repeated.

2. SINGLE STAGE HEAT WITHOUT DUCT HEATERS

Compressor circuit R to Y including lockout relay and pressure controls is the same as cooling. Blowercircuit R to G is the same as cooling. With system switch set to HEAT, no circuit is completed betweenR and O and reversing valve solenoid is not energized.

3. TWO STAGE HEAT WITH DUCT HEATERS

First stage heat is the same as single heating without duct heater. When the second stage thermostatbulb makes, a circuit is completed from C to W2, energizing the duct heater heat contactor, through theheating element and manual reset limit. C to W2 also simultaneously energizes the 24 volt coil on theinterlock relay, closing the contacts, which in turn energize the low voltage coil on the blower relay toclose the high voltage contacts and power the blower motor. The elements and blower remain energizedas long as C to W2 are made.

4. EMERGENCY HEAT

When the system switch is moved to EMER, the compressor circuit R to Y is disconnected. Control ofthe electric heaters is from C to W2 and W3 through the thermostat second stage heating bulb. Bloweroperation is controlled by the second stage heating bulb. Operation is the same as above, "Two StageHeat with Duct Heaters."
