Operating sequence

 

Cooling — When the system thermostat calls for cooling, 24

 

V is supplied to the “Y” and “G” terminals of the thermostat.

 

This completes the circuit to the contactor coil (C) and

 

indoor (evaporator) fan time delay relay (TDR). The

 

normally open contacts of C close and complete the circuit

 

to compressor motor (COMP) and to outdoor (condenser)

 

fan motor (OFM). Both motors start instantly. The IFM starts

 

according to the selection pin set-up on the Easy Select™

50XP

Board.

On the loss of the thermostat call for cooling, 24 v is

 

removed from both the “Y” and “G” terminals (provided the fan switch is in the “AUTO” position) deenergizing the compressor contactor and opening the contacts supplying power to compressor/OFM. After preselected delay, the IFM shuts off. If the thermostat fan selector switch is in the “ON” position, the IFM will run continuously at speed selected on Easy Select™ Board.

Heating — If accessory electric heaters are installed, on a call for heat, circuit R-W is made through the thermostat contacts. Circuit R-G is made which energizes the IFM. If the heaters are staged, then the thermostat closes a second set of contacts (W2) when second stage is required. When thermostat is satisfied, contacts open, deenergizing the heater relay. After a preselected delay, the IFM shuts off. If the thermostat fan selector switch is in the “ON” position, the IFM will run continuously at speed selected on Easy Select™ Board.

NOTE: On units with a Time Guard® II device: once the compressor has started and then stopped, it cannot be restarted again until 5 minutes have elapsed.

The indoor blower operation with a call for fan operation (G) in cooling mode will perform by the on/off delay profile selected at start up on the Easy Select™ Board.
