Abstract
A control system to selectively control the operation of the compressor of a mini-split air conditioning system including at least one remote evaporator operatively coupled to the compressor to receive refrigerant therethrough, a sensor to monitor the operation of the evaporator and to generate an operating control signal to turn-off the compressor when a predetermined operating condition is sensed at the evaporator and a condensate drain pan to receive or catch condensate from the evaporator, the control system comprising a condensate sensor disposed to sense condensate in the condensate drain pan at a predetermined level and to generate a condensate level signal fed to a battery powered control device including an isolated solid state relay coupled to the sensor by a control coupling device to generate a condensate level control signal fed to the sensor causing the sensor to generate the operating control signal fed to turn off the compressor when condensate within the condensate drain pan reaches the predetermined level.
