Heat Pump Principle of Operation

WINTER HEATING

1. Outdoor air enters heat pump.

2. Cold, heat-transfer section (outdoor coil) extracts heat from outdoor air as refrigerant evaporates from a liquid to a gas.

3. Refrigerant, compressed to a hot gas by heat pump, carries the heat to the hot heattransfer section (indoor coil).

4. Hot, heat-transfer section (indoor coil) releases the heat to indoor air as refrigerant condenses from a gas to a liquid.

5. Air handler circulates the heat throughout the home.

6. Refrigerant returns to outdoor coil and

evaporates once again to absorb more heat.

SUMMER COOLING

1. Indoor air enters the air handler section.

2. Cold, heat-transfer section (indoor coil) extracts heat from indoor air as refrigerant evaporates from a liquid to a cold gas.

3. Refrigerant, drawn to heat pump and compressed to a hot gas by heat pump, carries the heat outdoors.

4. Hot, heat-transfer section (outdoor coil) releases the heat as refrigerant condenses from a gas to a liquid.

5. Heat pump (outdoor fan) discharges the heat to outside air.

6. Refrigerant returns to indoor coil and evaporates once again to absorb more heat.

During cold weather heating operation, the

outdoor unit will develop a coating of snow and ice on the heat transfer coil. This is normal, and the unit will periodically defrost itself. During the defrost cycle, the outdoor fan will stop, and the compressor will continue to run and heat the outdoor coil, causing the snow and ice to melt. After the snow and ice have melted, some steam ma y rise from the outdoor unit as the warm coil causes some melted frost to evaporate.

TO OPERATE YOUR HEAT PUMP FOR AUTOMATIC COOLING AND HEATING—

1. Set the thermostat system switch to AUTO

and the thermostat fan switch to A UTO. (See

Figure 1)

Note: Thermostats will vary. Some models

will not include the AUT O mode , and others will have the A UTO in place of the HEAT and COOL, and some will include all three.

2. Set the thermostat temperature to the

desired heating and cooling temperature level(s). The outdoor unit and the indoor blower will then cycle on and off in either the heating or cooling mode of operation as required to automatically maintain the indoor temperature within the desired limits.

and when an accumulation of dust and dirt is visible on the air ﬁ lter. Inspect the ﬁ lter monthly .

b. Remove any leaves and grass clippings

from the coil in the outdoor unit, being careful not to damage the aluminum ﬁ ns.

c. Check for any obstruction such as twigs,

sticks, etc.

d. Certain models have external panels

fabricated from a premium grade of stainless steel designed to inhibit corrosion. For such units, if the unit is located in a coastal region or other area subjected to high concentrations of salt, then the unit should be hosed off after storms and monthly otherwise to maintain its new appearance.

TO SHUT OFF YOUR HEA T PUMP—

Set the thermostat system switch to OFF and the thermostat fan switch to AUTO. (See Figure 1) The system will not operate, regardless of the thermostat temperature selector(s) setting.

TO OPERATE THE INDOOR BLOWER CONTINUOUSLY—

Cooling — Gradually lower the thermostat temperature setpoint below the actual room temperature and observe that the outdoor unit and indoor blower energize. Feel the air being circulated by the indoor blower and verify that it is cooler than ambient temperature. Listen for any unusual noises. If present, locate and determine the source of the noise and correct as necessary.

Short Cycle Protection — With the system operating in COOLING mode, note the setpoint temperature setting of the thermostat, and gradually raise the setpoint temperature until the outdoor unit and indoor blower de-energize . Immediately lower the setpoint temperature of the thermostat to its original setting and verify that the indoor blower is energized and that the outdoor unit remains de-energized. Verify that, after approximately 5 minutes, the outdoor unit energizes and that the temperature of the air supplied to the facility is cooler than ambient temperature.

Heating — Lower the thermostat setpoint temperature to the lowest obtainable setting and set the thermostat function switch to HEATING. The indoor blower and outdoor unit should stop running. After a minimum of ﬁ ve minutes, increase the setpoint temperature of the thermostat to the maximum setting. V erify that the outdoor unit and indoor blower ha ve energized. Feel the air being circulated by the indoor blower and verify that it is warmer than ambient temperature. Listen for any unusual noises. If present, locate and determine the source of the noise and correct as necessary.

NOTE: Other sources for heating (i.e.: electric furnace, fossil fuel furnace, air handler with electric heat options, etc.) that interface with the unit should be functionally checked to v erify system operation and compatibility . Refer to the installation instructions for this equipment and perform a functional checkout in accordance with the manufacturer’s instructions.

OUTDOOR THERMOSTAT (if supplied)

The outdoor thermostat prevents the electrical auxiliary heat (if used) from operating above 40°F outdoor ambient temperature.

Defrost Cycle Timer — The defrost cycle timer controls the time interval of the hot gas defrost after the defrost sensor closes. It is located in the lower left corner of the defrost control board. Three interval settings are available: 30 minutes, 60 minutes, and 90 minutes. Time setting selection is dependent on the climate where the unit is being installed.

Example 1. Dry climate of Southern Arizona. A 90 minute setting is recommended.

Example 2. Moist climate of Seattle, Washington. A 30 minute setting is recommended.

To set the cycle timer, place the timing pin on the defrost control board to the desired time

interval post. Note: All units are shipped from the factory with

the default time setting of 30 minutes. Maximum heating performance can be achieved b y setting the time to 90 minutes.

DEFROST CONTROL BOARD OPERATION AND TESTING

1. Terminals “R”-”C” must have 24±V present between them in order for the time dela y and defrost sequences to be operational.

2. Jumper the “T2”-”DFT” test pins. This will indicate to the board that the defrost T-stat is closed(if the compressor is running). Defrost T-stat is closed at 32° or below and is open at 68° or above. But it’s state is unknown if the temperature is between 32°F and 68°F. The defrost thermostat tells the board whether a defrost cycle needs to be started or terminated. With the DFT closed the unit will run for 30/60/90 minutes in heat mode and then defrost the outdoor coil. The defrost will turn off the outdoor fan, turn on the compressor and raise the coil temperature to 68°F. This will open the DFT and terminate the defrost. If the DFT does not open the defrost will end after 10 minutes.

3. Defrost board speed-up. With compressor running in heat mode, next jump the “Test” pin to “C” on ter minal strip. This will initiate a defrost test in 5, 10 or 15 seconds (This is determined by the 30, 60 or 90 minute defrost pin settings. The factory setting will be 30 minutes). Note that this will bypass the compressor off delay when the unit goes into defrost test and if left in defrost test, the delay will be bypassed when the test is terminated by the processor. If the jumper is removed before the test is over the processor will perform the remainder of a normal defrost. See step 2 above.

4. Remove the jumpers.

Note: The delay/no-delay pin concerns compressor operation during defrosts. The default setting is delay. Reciprocating compressors

Page 10

should only use this setting in conjunction with an approved hard start kit. Scroll compressors that have noise issues while going into or coming out of defrost should use this 30 second delay to reduce the defrost noise. T o switch from no-delay to delay remove the pin from the “no-delay” pin location and shift it to the “delay” pin location.

Optional Equipment — A functional checkout should be performed in accordance with the checkout procedures supplied with the

equipment.

Adjustment of Refrigerant Charge:

Speed up changes:

Manually initiating a defrost will cause the compressor to run continually when entering defrost.

Normal defrost operation:

To test normal defrost operation when the temperature is above 35°F, jumper “R” to “DFT” on the 624656 board and allow the unit to run for 30 minutes. Defrost will continue until the “R” to “DFT” jumper is removed or for 10 minutes. Remove the jumper.

The 5 minute time delay feature can be shortened 1 time to 1 second by jumping the “T est” to “C” terminal. Remove the jumper and repeat as desired.

Note: If jumper is left on the “Test” to “common” pins permanently, the defrost cycle will become inoperable.

Defrost Test Procedure for 624656

1. Jumper “T2” to “DFT” at the test terminals.

2. With unit running in heat mode, shor t the “TEST” terminal to the common terminal near it. This will speed up the board and cause it to enter defrost mode in 5/10/15 seconds depending on the defrost time selection. Compressor delay will not function during speed-up.

3. This test will end in 5 seconds if the “TEST”common short is not removed.

4. Remov e both the short and the “T2” to “DFT” jumper to terminate the defrost cycle. The 30 second compressor delay should operate normally.

5. Test is complete, reset ther mostat to home owner preference.

CAUTION:

Split system heat pump equipment contains liquid and gaseous refrigerant under pressure. Adjustment of refrigerant charge should only be attempted by qualified, trained personnel thoroughly familiar with the equipment. Under no circumstances should the homeowner attempt to install and/or service this equipment. Failure to comply with this warning could result in equipment damage, personal injury, or death.

NOTE: The following Refrigerant Charging

Charts are applicable to listed assemblies of equipment and at listed airﬂ ows for the indoor coil. Assemb lies of indoor coils and outdoor units not listed are not recommended and deviations from rated airﬂ ows or non-listed equipment combinations may require modiﬁ cations to the expansion device(s) and refrigerant charging procedures for proper and efﬁ cient system operation.

Refrigerant Charging Chart — Refer to Refrigerant Charging Charts for correct system charging, and to Oriﬁ ce Usage Chart for correct restrictor sizes.

NOTE: Linesets over 15 feet in length may require additional refrigerant charge. NORDYNE recommends 0.6 oz. of refrigerant per foot for any lineset over 15 feet.
