CONTROLS

OPERATING SEQUENCE

Heating Ð When the thermostat calls for heating, terminal ``W'' is energized, starting the induced-draft motor. When the hall- effect sensor on the induced-draft motor senses that it has reached the required speed, the burner ignition sequence be- gins. The indoor (evaporator) fan motor (IFM) is energized 45 seconds after ¯ame is established. When the thermostat is satis®ed and ``W'' is deenergized, the IFM stops after a 45-second time-off delay.

Cooling Ð 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 (evapo- rator) fan relay (IFR). The normally open contacts of C close and complete the circuit through compressor motor (COMP) to

outdoor (condenser) fan motor (OFM). Both motors start in- stantly. The set of normally open contacts of IFR close and com- plete the circuit through IFM. The IFM starts instantly.

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 a 30-second delay, the IFM shuts off. If the thermostat fan selector switch in is the ``ON'' position, the IFM will run continuously.

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