SEQUENCE OF OPERATION The heat pump defrost control board (HPC) has an option of 30, 60 or 90-minute setting. All models are shipped from COOLING – Circuit R-Y makes at thermostat pulling in the factory on the 60-minute pin. If special circumstances compressor contactor, starting the compressor and outdoor require a change to another time, remove the wire from the motor.
TROUBLESHOOTING SOLID STATE HEAT PUMP CONTROL 4. Set system switch to “heat” or “cool”. Adjust TROUBLESHOOTING PROCEDURE thermostat to call for heat or cool. The indoor blower, compressor and outdoor fan should start. 1. NOTE: A thorough understanding of the defrost cycle sequence is essential.
CHECKING TEMPERATURE SENSOR 3. Check resistance reading to chart of resistance. Use OUTSIDE UNIT CIRCUIT sensor ambient temperature. (Tolerance of part is ± 10%.) 1. Disconnect temperature sensor from board and from outdoor coil. 4. If sensor resistance reads very low, then sensor is shorted and will not allow proper operation of the 2.
