SEQUENCE OF OPERATION A. CONTINUOUS FAN SAFETY SWITCHES Thermostat closes R to G. Unit is equipped with a limit switch for each separate heating element. G energizes Time Delay Relay (TDR). Time Delay Relay (TDR) energizes Fan Relay (FR) within 30 seconds. When Fan Relay (FR) is energized, circuit is complete to Indoor Blower Motor. When G is de-energized, there is a 3 second delay before Fan Relay (FR) opens. B. COOLING MODE Thermostat closes R to G, R to Y, and R to O (heat pump only).
