If phasing is correct, circuit R-Y energizes contactor, starting outdoor-fan motor and compressor circuit. R-G energizes indoor unit-blower relay, starting indoor-blower motor on high speed. NOTE: If the phasing is incorrect, the contactor will not be energized. To correct the phasing, interchange any 2 of the 3 power connections on the field side. When thermostat is satisfied, its contacts open, de-energizing the contactor and blower relay. Compressor and motors should stop. NOTE: If indoor uni
