Without accessory economizer — Upon a request for cooling from the space thermostat, terminals Y1 and G will be energized with 24 v. As a result, the indoor-fan contactor (IFC), outdoor-fan contactor (OFC) and Compressor contactor no. 1 (C1) will be energized, which in turn will energize the indoor fan, outdoor fan and Compressor no. 1, respectively. If the space thermostat calls for a second stage of cooling by supplying 24 v to Y2, Compressor contactor no. 2 (C2) will be energized, thus energi

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
