High and Low Pressure Control Switches

The high pressure control stops the compressor in the event of excessive pressure in the high side of the system and permits the compressor to be started again when the pressure drops to the cut-in setting of the high pressure control (by pushing the controller start button). The low pressure control stops and starts the compressor at the proper predetermined suction pressures. These two controls are contained in one switch box called the dual pressurestat.
