OPERATION
Sequence of Operation
Uponinitial “power up” to unit, there is a 3-minute time delay
to the compressor contactor (R to Y).Any 24V interrupt (R,
C) to the defrost control will initiate the
3-minute delay to the contactor.
Cooling
When the thermostat is in the cooling mode, the O circuit is
powered which energizes the reversing valve. Upon cooling
