GENERAL INSTRUCTIONS

IMPORTANT

The equipment covered in this manual is to be installed by trained, experienced service and installation technicians.

Any heat pump is more critical of proper operating charge and an adequate duct system than a straight air conditioning unit. All duct work, supply and return ducts, must be properly sized for the design airflow requirement of the equipment. ACCA is an excellent guide to proper sizing.

All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conserve energy and prevent condensation or moisture damage.

SHIPPING DAMAGE

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

GENERAL

The refrigerant system is completely assembled and charged. All internal wiring is complete.

The unit is designed for use with or without duct work.

Flanges are provided for attaching the supply and return ducts.

These instructions explain the recommended method to install the air cooled self-contained unit and the electrical wiring connections to the unit.

These instructions and any instructions packaged with any separate equipment required to make up the entire heat pump system should be carefully read before beginning the installation. Note particularly “Starting Procedure” and any tags and/or labels attached to the equipment.

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

FIELD INSTALLED HEATER PACKAGES

(OPTIONAL)

These packaged heat pumps are manufactured without supplementary electric heaters. Supplementary heaters are available for simple, fast field installation.

A separate power circuit is required for the supplementary heaters.

IMPORTANT: Refer to Table 1 when designing duct work for maximum available static pressure with heater installed.

Refer to Tables 2 and 4 for proper application information on all available heater combinations and what units they can be used with. It also shows the applicable circuit ampacities, fuse size, and wire size for each heater combination.

LOCATION

GENERAL

The unit must be located outside, or in a well ventilated area. It must not be in the space being heated or cooled. A sound absorbing material should be considered if the unit is to be installed in such a position or location that might cause transmission of sound or vibration to the living area or adjacent buildings.

SLAB MOUNTING

In areas where winter temperatures DO NOT go below

32°F for periods over twelve hours, the unit may be slab mounted at grade level. When installing unit at grade level, install on a concrete slab at least four inches above finished grade level. Slab should have a slope tolerance away from the building structure of at lease ¼ inch per foot, while being level from side to side. This will prevent ice buildup under the unit during defrost cycles. Place slab in a location where runoff water from higher ground will not collect around unit. See Figure 2.

A minimum of 24 inches should be provided between the coil inlet and any building surfaces. Provide a minimum of three feet clearance on the service access side of the unit.

See Figure 3.

When a unit is installed in areas where low ambient temperatures or strong winter winds exist, it should be placed so prevailing winter winds are not in direct line with the heat pump coil. If this is not possible, a wind barrier should be constructed. Place barrier 24 inches from the coil inlet side of the unit and in the direction of prevailing winds. Size barrier at least the same height and width as the unit. This may be necessary on ground level installations, also. See Figure 3.

WINTER INSTALLATION BELOW 32°F

In areas where winter conditions go below 32°F for extended periods, the unit must be elevated above the mounting surface to prevent snowfall or defrost ice accumulation from interfering with the operation of the unit. A minimum of twelve inch elevation is recommended, while greater elevation may be required for areas of high snow accumulation. Poured concrete, steel framework, brick, cement block, etc., can be utilized to construct a suitable raised mounting platform. See

Figure 4.

INSTALLATION

TYPICAL INSTALLATIONS

1.

ROOF MOUNTED – The unit is mounted on a sturdy base on the roof of the building. Return air to the unit is brought through a single return grille (grilles with built-in filters are best since they enable easy access for filter changing). Return air ducts are attached to the lower section of the front panel. Supply air is brought from the unit to attic duct work or to a furred down hall. Supply air duct is attached to the top of the front panel.

CAUTION: All outdoor duct work must be thoroughly insulated and weatherproofed. All attic duct work must be thoroughly insulated. Two inch thick insulation with suitable vapor barrier is recommended for both outdoor and attic runs.

In roof top installation, as in all installations, the heat pump must be level from side to side. However, the unit should have a pitch along the length to assure complete external drainage of precipitation and of defrost condensate.

2.

CRAWL SPACE – Duct work installed in crawl space must be well insulated and provided with a vapor barrier. In addition, the crawl space must be thoroughly ventilated and provided with a good vapor barrier as a ground cover. It is most desirable to install the unit outdoors rather than inside the crawl space, so that it will be readily accessible for service. In addition, it is necessary to dispose of the condensate from the outdoor coil on the heating cycle, and this is virtually impossible with the unit installed inside the crawl space.

3.

SLAB MOUNTED AT GROUND LEVEL – This type installation is ideal for homes with a slab floor construction where a roof mounted unit is not desired.

The supply and return duct work can be run through a furred closet space.

4.

THROUGH THE WALL – This type installation requires a suitable framework to be fabricated capable of withstanding the unit weight. Normally the unit will be insulated so as to minimize supply and return duct work.

OTHER INSTALLATIONS – Many other installations are possible with the packaged heat pump. No matter what the installation, always consider the following facts:

A. Insure that the discharge air is not obstructed in any way so as to cause operation difficulties.

B. The indoor coil drain pan is equipped with a coupling that must be piped through a condensate drain trap to a suitable drain.

C. Always mount the unit is such a position that it may be easily reached for servicing and maintenance.

D. Insure that the unit is clear so that proper air flow over the outdoor coil will be maintained.

If this unit is operated in cooling below a 55° outdoor ambient temperature, the installation of low ambient controls (CMH-15) to unit is required.

CONDENSATE DRAIN TRAP

It is very important to provide a trap in the condensate drain line to allow a positive liquid seal in the line and assure correct drainage from the coil condensate pan.

Install condensate drain trap shown in Figure 5. Use drain connection size or larger. Do not operate unit without trap. Unit must be level or slightly inclined toward drain.

With a trap installed on a unit located in an unconditioned area, water in the trap may freeze. It is recommended that the trap material be of a type that will allow for expansion of water when it freezes.

AIR FILTERS

Air filters for the return air side of the system are not provided as part of the various types of applications for these models, and must be field supplied and installed as part of the final installation.

Prior thought should be given to return air location and placement of the air filter(s). The air filter(s) must be of adequate size and readily accessible to the operator of the equipment. Filters must be adequate in size and properly maintained for proper operation. If this is not done, excessive energy use, poor performance, and multiple service problems will result. It is impossible to oversize air filters. Generous sizing will result in cleaner air and coils as well as lower operating costs and extend the time between required changes. Table 5 shows minimum filter areas and recommended filter sizes. Actual filter sizes can vary with the installation due to single or multiple returns utilizing a filter/grille arrangement or being placed immediately ahead of the indoor coil face in the return air duct.

WIRING – MAIN POWER

Refer to the unit rating plate for wire sizing information and maximum fuse size. Each outdoor unit is marked with a “Minimum Circuit Ampacity”. This means that the field wiring used must be sized to carry that amount of current.

If field installed heaters are added to the basic unit, a second separate power supply circuit will be required. The heater rating plate located adjacent to the basic unit rating plate will show the appropriate circuit ampacity fuse size, etc. (Also see “Electrical Data” on pages 5 and 7.) All models are suitable for connection with copper wire only.

These instructions must be adhered to. Refer to the

National Electrical Code for complete current carrying capacity data on the various insulation grades of wiring material.

FIGURE 6

LOW VOLTAGE WIRING

The unit rating plate lists a “Maximum Time Delay Fuse” or “HACR” type circuit breaker that is to be used with the equipment. The correct size must be used for proper circuit protection and also to assure that there will be no nuisance tripping due to the momentary high starting current of the compressor.

WIRING – 24V LOW VOLTAGE

CONTROL CIRCUIT

Eight (8) wires should be run from thermostat subbase to the 24V terminal board in the unit. A ten conductor,

18 gauge copper, color-coded thermostat cable is recommended. The connection points are shown in

THERMOSTAT INDICATOR LAMPS

The red lamp marked “EM. HT.” comes on and stays on whenever the system switch is placed in Em. Ht. position.

The green lamp marked “Check” will come on if there is any problem that prevents the compressor from running when it is supposed to be.

EMERGENCY HEAT POSITION

The operator of the equipment must manually place the system switch in this position. This is done when there is a known problem with the outdoor section, or when the green

“Check” lamp comes on indicating a problem.

TRANSFORMER TAPS

230/208V, 1 phase and 3 phase equipment employ dual primary voltage transformers. All equipment leaves the factory wired on 240V tap. For 208V operation, reconnect from 240V to 208V tap. The acceptable operating voltage range for the 240 and 208V taps are:

TAP RANGE

240

208

253 – 216

220 – 187

NOTE: The voltage should be measured at the field power connection point in the unit and while the unit is operating at full load (maximum amperage operating condition).

COMPRESSOR CUTOFF THERMOSTAT and OUTDOOR THERMOSTAT WIRING

Heat pump compressor operation at outdoor temperatures below 0°F are neither desirable not advantageous in terms of efficiency. Since most equipment at time of manufacture is not designated for any specific destination of the country and most of the equipment is installed in areas not approaching the lower outdoor temperature range, the compressor cutoffs are not factory installed.

Outdoor thermostats are available to hold off various banks of electric heat until needed as determined by outdoor temperature. The set point of either type of thermostat is variable with geographic region and sizing of the heating equipment to the structure. Utilization of the Heating

Application Data and the heat loss calculation of the building are useful in determining the correct set points.

Refer to Installation Instructions of CMH-14 Outdoor

Thermostat Kit for more information.

These units require R-410A refrigerant and Polyol Ester.

GENERAL:

1. Use separate service equipment to avoid cross contamination of oil and refrigerants.

2. Use recovery equipment rated for R-410A refrigerant.

3. Use manifold gauges rated for R-410A (800 psi/250 psi low).

4. R-410A is a binary blend of HFC-32 and HFC-125.

5. R-410A is nearly azeotropic - similar to R-22 and

R-12. Although nearly azeotropic, charge with liquid refrigerant.

6. R-410A operates at 40-70% higher pressure than

R-22, and systems designed for R-22 cannot withstand this higher pressure.

7. R-410A has an ozone depletion potential of zero, but must be reclaimed due to its global warming potential.

8. R-410A compressors use Polyol Ester.

9. Polyol Ester oil is hygroscopic; it will rapidly absorb moisture and strongly hold this moisture in the oil.

10. A liquid line dryer must be used - even a deep vacuum will not separate moisture from the oil.

11. Limit atmospheric exposure to 15 minutes.

12. If compressor removal is necessary, always plug compressor immediately after removal. Purge with small amount of nitrogen when inserting plugs.

TOPPING OFF SYSTEM CHARGE

If a leak has occurred in the system, Bard Manufacturing recommends reclaiming, evacuating (see criteria above), and charging to the nameplate charge. Topping off the system charge can be done without problems.

With R-410A, there are no significant changes in the refrigerant composition during multiple leaks and recharges. R-410A refrigerant is close to being an azeotropic blend (it behaves like a pure compound or single component refrigerant). The remaining refrigerant charge, in the system, may be used after leaks have occurred and then “top-off” the charge by utilizing the charging charts on the inner control panel cover as a guideline.

REMEMBER: When adding R-410A refrigerant, it must come out of the charging cylinder/tank as a liquid to avoid any fractionation, and to insure optimal system performance. Refer to instructions for the cylinder that is being utilized for proper method of liquid extraction.

START UP

SAFETY PRACTICES:

1. Never mix R-410A with other refrigerants.

2. Use gloves and safety glasses, Polyol Ester oils can be irritating to the skin, and liquid refrigerant will freeze the skin.

3. Never use air and R-410A to leak check; the mixture may become flammable.

4. Do not inhale R-410A – the vapor attacks the nervous system, creating dizziness, loss of coordination and slurred speech. Cardiac irregularities, unconsciousness and ultimate death can result from breathing this concentration.

5. Do not burn R-410A. This decomposition produces hazardous vapors. Evacuate the area if exposed.

6. Use only cylinders rated DOT4BA/4BW 400.

7. Never fill cylinders over 80% of total capacity.

8. Store cylinders in a cool area, out of direct sunlight.

9. Never heat cylinders above 125°F.

10. Never trap liquid R-410A in manifold sets, gauge lines or cylinders. R-410A expands significantly at warmer temperatures. Once a cylinder or line is full of liquid, any further rise in temperature will cause it to burst.

START UP NOTES

For improved start up performance, wash the indoor coil with dishwasher detergent.

START UP AND OPERATION

THREE PHASE SCROLL COMPRESSOR

START UP INFORMATION

(Models PH13363-B, PH13422-B, -C; PH13482-B,

-C; PH13602-B, -C)

All units with three phase scroll compressors are equipped with a three phase line monitor to prevent compressor damage due to phase reversal.

The phase monitor in this unit is equipped with two LED’s.

If the “Y” signal is present at the phase monitor and phases are correct, the green LED will light.

If phases are reversed, the red fault LED will be lit and compressor operation is inhibited.

If a fault condition occurs, reverse tow of the supply leads to the unit. Do not reverse any of the unit factory wires as damage may occur.

SEQUENCE OF OPERATION

BLOWER ONLY – When the “Fan” switch on the room thermostat is placed in the “On” position (circuit R-G makes), the blower will energize and run until the “Fan” switch is placed back into the “Auto” position. This will allow for constant air circulation at a lower airflow during times when the unit is not in operation for cooling or heating.

COOLING – On a call for cooling from the room thermostat (circuit R-Y makes), the blower will energize

(circuit R-G is automatic when R-Y makes) as well as the compressor, and outdoor fan motor. Note that if the “Fan” switch on the room thermostat is in the “On” position and the blower is already in operation, then the motor will ramp up to the required speed for cooling.

HEATING (1st Stage) – On a call for heating from the room thermostat (circuit R-Y&B makes), the blower will energize (circuit R-G is automatic when R-Y makes) as well as the compressor, outdoor fan motor, and reversing valve solenoid coil. This will place the system into heat pump operation to maintain the thermostat set temperature.

Note that if the “Fan” switch on the room thermostat is in the “On” position and the blower is already in operation, then the motor will ramp up to the required speed for heating.

HEATING (1st Stage Defrost) – During the defrost cycle, the heat pump control will energize electric heaters, if installed, (circuit R-W2 makes), allowing room temperature to be maintained during heat pump defrost operation.

HEATING (2nd Stage) – If the operation of the heat pump will not maintain the set room temperature, then the thermostat will call for additional heat from electric heaters to help maintain the set temperature. On a call for second stage heating from the room thermostat (circuit R-W2 makes), backup electric heaters will be energized if installed.

HEATING (Em Heat) – When the room thermostat is placed in the “Em Heat” position (circuit R-E makes), the blower and electric heaters, if installed, will energize on second stage heat (circuit R-W2&W3 makes), with the compressor and outdoor fan motor locked out of operation.

DEFROST CYCLE

The defrost cycle is controlled by temperature and time on the solid state heat pump control. See Figure 9.

When the outdoor temperature is in the lower 40°F temperature range or colder, the outdoor coil temperature is

32°F or below. This coil temperature is sensed by the defrost sensor mounted near the bottom of the outdoor coil.

Once the Heat Pump Control board sees the resistance of the defrost sensor has been below the resistance of 34545

(30°F) for 60 minutes of accumulated run time. The Heat

Pump Control Board will start the defrost cycle by deenergizing the reversing valve and condenser fan. It will also send a signal to W2 to energize the electric heat if equipped. When the Heat Pump Control Board reads the resistance of the defrost sensor has risen to 16547 (57°F) or it has been in defrost for 10 minutes the defrost cycle will terminate.

After 30 minutes at 30°F or below, the heat pump control will place the system in the defrost mode.

During the defrost mode, the refrigerant cycle switches back to the cooling cycle, the outdoor motor stops, electric heaters are energized, and hot gas passing through the outdoor coil melts any accumulated frost. When the temperature rises to approximately 57°F the coil sensor will send a signal to the heat pump control which will return the system to heating operations automatically.

If some abnormal or temporary condition such as a high wind causes the heat pump to have a prolonged defrost cycle, the heat pump control will restore the system to heating operation automatically after 10 minutes.

There are three settings on the heat pump control – 30 minute, 60 minute and 90 minute. Models are shipped wired on the 60 minute setting for greatest operating

FIGURE 9

HEAT PUMP CONTROL BOARD economy. If special circumstances require a change to another time, remove wire connected to terminal 60 and reconnect to desired terminal. Refer to Figure 9. The manufacturer’s recommendation is for 60 minute defrost cycles.

There is a cycle speed up jumper on the control. This can be used to reduce the time between defrost cycle operation without waiting for time to elapse.

Use a small screwdriver or other metallic object, or another

1/4 inch QC to short between the SPEEDUP terminals to accelerate the HPC timer and initiate defrost.

Be careful not to touch any other terminals with instrument used to short the SPEEDUP terminals. It may take up to 10 seconds with the SPEEDUP terminals shorted for the speedup to be completed and the defrost cycle to start.

As soon as the defrost cycle kicks in remove the shorting instrument from the SPEEDUP terminals.

Otherwise the timing will remain accelerated and run through the 1 minute maximum defrost length sequence in a matter of seconds and will automatically terminate the defrost sequence.

There is an initiate defrost jumper (sen jump) on the control that can be used at any outdoor ambient during the heating cycle to simulate a 0° coil temperature. This can be used to check defrost operation of the unit without waiting for the outdoor ambient to fall into the defrost region.

By placing a jumper across the SEN JMP terminals (a 1/4 inch QC terminal works best) the defrost sensor mounted on the outdoor coils is shunted out and will activate the timing circuit. This permits the defrost cycle to be checked out in warmer weather conditions without the outdoor temperature having to fall into the defrost region.

In order to terminate the defrost test in the SEN JMP jumper must be removed. If left in place too long the compressor could stop due to the high pressure control opening because of the high pressure condition created by operating in the cooling mode with outdoor fan off.

Pressure will rise fairly fast as there is likely no actual frost on the outdoor coil in this artificial test condition.

There is also a 5 minute compressor time delay function built into the HPC,

This is to protect the compressor from instances it is helpful to the service technician to override or speed up this timing period, and shorting out the speedup terminals for a few seconds can do this.

TROUBLESHOOTING

SOLID STATE HEAT PUMP CONTROL

TROUBLESHOOTING PROCEDURE

NOTE: A thorough understanding of the defrost cycle sequence is essential. Review that section earlier in this manual prior to troubleshooting the control.

1. Turn on AC power supply to unit.

2. Turn thermostat blower switch to “fan on” – the indoor blower should start. (If it doesn’t, troubleshoot indoor unit and correct problem.)

3. Turn thermostat blower to “auto” position. Indoor blower should stop. NOTE: Many models have a

1-minute blower time delay on “off” command; wait for this to time-out.

4. Set system switch to “heat” or “cool”. Adjust thermostat to call for heat or cool. The indoor blower, compressor and outdoor fan should start.

NOTE: If there was no power to 24 volt transformer, the compressor and outdoor fan motor will not start for 5 minutes. This is because of the compressor short cycle protection.

CHECKING TEMPERATURE SENSOR

CHECK OUT

1. Disconnect temperature sensor from board and from outdoor coil.

2. Use an ohmmeter and measure the resistance of the sensor. Also use ohmmeter to check for short or open.

3. Check resistance reading to chart of resistance; use sensor ambient temperature. (Tolerance of part is

± 10%.)

4. If sensor resistance reads very low, then sensor is shorted and will not allow proper operation of the heat pump control.

5. If sensor is out of tolerance, shorted, open, or reads very low ohms then it should be replaced.

SERVICE

SERVICE HINTS

1. Caution homeowner to maintain clean air filters at all times. Also, not to needlessly close off supply and return air registers. This reduces airflow through the system which shortens equipment service life as well as increasing operating costs.

2. Switching to heating cycle at 75°F or higher outside temperature may cause a nuisance trip of the high pressure switch.

3. The heat pump wall thermostats perform multiple functions. Be sure that all function switches are correctly set for the desired operating mode before trying to diagnose any reported service problems.

4. Check all power fuses or circuit breakers to be sure that they are the correct rating.

5. Periodic cleaning of the outdoor coil to permit full and unrestricted airflow circulation is essential.

PRESSURE SERVICE PORTS

High and low pressure service ports are installed on all units so that the system operating pressures can be observed. Pressure tables can be found in Tables 11 & 12 in this manual covering all models on both cooling and heating cycles. It is imperative to match the correct pressure table to the unit by model number.

REFRIGERANT CHARGE

The correct system R-410A charge is shown on the unit rating plate.

You can reference Tables 11 & 12 to validate proper system operation. However, it is recommended that if incorrect charge is suspected, the system refrigerant be reclaimed, evacuated and charged to the nameplate refrigerant charge quantity and type.

The nameplate charge quantity is optimized for thermal performance and efficiency of this self-contained package system.

FAN BLADE SETTINGS

Shown in Figure 10 are the correct fan blade setting dimensions for proper air delivery across the outdoor coil.

Any service work requiring removal or adjustment in the fan and/or motor area will require that the dimensions in

Table 10 be checked and blade adjusted in or out on the motor shaft accordingly.

SUCTION AND DISCHARGE TUBE

BRAZING

Compliant Scroll compressors have copper plated steel suction and discharge tubes. These tubes are far more rugged and less prone to leaks than copper tubes used on other compressors. Due to different thermal properties of steel and copper, brazing procedures may have to be changed from those commonly used.

To disconnect: heat joint Areas 2 and 3 slowly and uniformly until braze material softens and the tube can be pulled out of suction fitting. (See Figure 11.)

To connect:

– Recommended brazing materials: silfos with minimum 5% silver or silver braze material with flux.

FIGURE 11

BRAZING DIAGRAM

– Reinsert tube into fitting.

– Heat tube uniformly in Area 1 moving slowly to

Area 2. When joint reaches brazing temperature, apply brazing material. (See Figure 11.)

– Heat joint uniformly around the circumference to flow braze material completely around the joint.

– Slowly move torch into Area 3 to draw braze material into joint. (See Figure 11.)

– Do not overheat joint.

1 Motor will deliver consistent CFM through voltage supply range with no deterioration

(197-253V for all 230/208V models).

2 Continuous CFM is the total air being circulated during continuous (manual fan) mode.

3 Will occur automatically with a call for "Y" for cooling mode operation.

4 Will occur automatically with a call for "W1" for heating mode operation.

™ MOTORS

NOTE: Bard Models PH13242; PH13302; PH13363-A, -B; PH13422-A, -B, -C; PH13482-A, -B, -C; PH13602-A, -B, -C contain the X13-Series Motors.

If the Motor is Running

1. It is normal for the motor to rock back and forth on start up.

Do not replace the motor if this is the only problem identified.

2. If the system is excessively noisy, does not appear to change speeds in response to a demand (Heat, Cool, Other), or is having symptoms during the cycle such as tripping limit or freezing coil, check the following: a. Wait for programmed delays to time out.

b.Ensure that the motors control inputs are wired to the factory supplied wiring diagram to insure motor is getting proper control signals and sequencing.

c. Remove the filter and check that all dampers, registers, and grilles are open and free flowing. If removing the filters corrects the problem, clean or replace with a less restrictive filter. Also check and clean the blower wheel or coil as necessary.

d.Check the external static pressure (total of both supply and return) to insure that you are within the ranges as listed on the unit serial plate. If higher than allowed, additional duct work is needed.

e. If the motor does not shut off at the end of the cycle, wait for any programmed delays to time out (no more than 90 seconds). Also make sure that there is no call for

“Continuous Fan” on the "G" terminal.

f. If the above diagnostics do not solve the problem, confirm the voltage checks in the next section below, then continue with the “Model X13 Communication Diagnostics”.

If the Motor is Not Running

1. Check for proper high voltage and ground at the (L/L1) (G) (N/

L2) connections at the motor (see Figure 12). Correct any voltage issues before proceeding to the next step. The X13 Motor is voltage specific. Only the correct voltage should be applied to the proper motor. Input voltage within plus or minus 10% of the nominal 230

VAC is acceptable.

2. If the motor has proper high voltage and ground at the (L/L1)

(G) (N/L2) connections, then continue with the “Model X13

Communication Diagnostics”.

Model X13 Communication Diagnostics

The X13 motor is communicated through 24 VAC low voltage

(Thermostat Control Circuit Wiring).

1.

Start with unit wiring diagram to confirm proper connections and voltage (see Figure 13).

2. Initiate a demand from the thermostat and check the voltage between the common and the appropriate motor terminal (1-5). ("G" input is typically on terminal #1, but refer to wiring diagram!) a. If the low voltage communication is not present, check the demand from the thermostat. Also check the output terminal and wire(s) from the terminal strip or control relay(s) to the motor.

b. If the motor has proper high voltage as identified above (Motor not Running #1), and proper low voltage to a programmed terminal, and is not operating, the motor is failed, and will require replacement.
