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.
