16 CONTROLS Operating sequence When power is supplied to unit, the transformer (TRAN) is energized. On units with crankcase heater, heater is also energized. Cooling With the thermostat in the cooling position, the thermostat makes circuit R O. This energizes the reversing valve solenoid (RVS) and places the unit in standby condition for cooling. As the space temperature rises, the thermostat closes circuit R Y. A circuit is made to contactor (C), starting the compressor (COMP) and outdoor fan motor (OFM). Circuit R G is made at the same time and starts the indoor fan motor (IFM). When the thermostat is satisfied, contacts open, deenergizing C. The COMP and OFM stop, and the IFM stops after the preselected time delay. Heating On a call for heat, thermostat makes circuits R Y and R G. A circuit is made to C, starting COMP and OFM. Circuit R G also is completed, energizing IFR and starting IFM after the selected time delay. Should room temperature continue to fall, circuit R W is made through second stage thermostat. If optional electric heat package is used, a relay is energized, bringing on first bank of supplemental electric heat. When thermostat is satisfied, contacts open, deenergizing contactor and relay; motors and heaters deenergize. Defrost Defrost board (DB) is a time and temperature control, which includes a field selectable time period (dip switch 1 and 2 on the board) between checks for defrost (30, 60, 90, or 120 minutes). Electronic timer and defrost cycle start only when contactor is energized and defrost thermostat (DFT) is closed. The defrost board is also equipped with a third dip switch for selecting Quiet Shift operation. The Quiet Shift operation turns compressor off at defrost initiation and termination. Unit is factory shipped with quiet shift turned off. Defrost mode is identical to cooling mode, except outdoor fan motor stops and a bank of optional electric heat turns on to warm air supplying the conditioned space. NOTE: 1. Compressor time delay occurs through the defrost control board. 2. Defrost control board has built in 5 minute compressor delay; once the compressor has started and then stopped, it cannot be restarted again until 5 minutes have elapsed. 16 SPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICE
