4.9 Relay

The contacts of the single pole, single throw relay complete the power circuit to the compressor. The contacts are closed when power is provided to the relay coil via the control circuit. The control circuit includes the power switch, low pressure control, time delay (HP model), defrost thermostat and timer.

4.10 Time Delay (HP model only)

The HP model has a time delay relay in the compressor control circuit. This relay delays the compressor start about 2 minutes after the power switch is turned on. This reduces the unit’s starting amp draw by starting the blower and compressor at different times. This reduces the chance of tripping a circuit breaker during hard start situations, such as when the unit has been stored in a cold place. It also reduces compressor short cycling after the compressor has stopped.
