Satellite Short Cycle Control Relay
The Satellite short cycle control relay is intended to prevent rapid cycling when the
compressor goes into pumpdown mode. It is a single-shot time-delay relay. When the low
pressure control opens on a decrease in pressure, the short cycle control relay becomes
energized and starts timing. After 3 minutes (regardless of the action of the low pressure
control) this relay will close, thereby re-engaging the control circuit and allowing the
compressor to run again.
