Abstract:
1. A control system to selectively control the operation of the compressor of an air conditioning system including at least one remote evaporator and a control sensor to sense at least one air conditioning system operating condition, the remote evaporator being operatively coupled to the compressor to receive refrigerant therethrough and an electronics system coupled between the compressor and the evaporator by a control link to selectively generate an operating control signal to turn-off the compressor when a predetermined operating condition is sensed at the evaporator by the control sensor and a condensate drain pan to receive condensate from the evaporator, said 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 in response thereto, a control device coupled to said condensate sensor to receive said condensate level signal and to generate a control signal in response to said condensate level signal, said control device coupled to the control sensor of the evaporator to feed said control signal from said control device to the control sensor to generate a sensor control signal in response to said control signal, said control sensor coupled to the electronics system to feed said sensor control signal to the electronics system and said control device coupled to the electronics system to feed said control signal from said control device to the electronics system such that when said condensate level signal is generated the electronics system receives said control signal from said control device and said sensor control signal from the control sensor to generate the operating control signal to turn off the compressor when condensate within the condensate drain pan reaches the predetermined level, said control system further including a coupling harness to operatively couple said control device, the control sensor and the electronics system together, said coupling harness comprising a control device interface connector coupled to the electronics system and to the control sensor by an electronics system interface connector and a control sensor interface connector respectively to feed said control signal from said control device to the electronics system and to the control sensor when the condensate line in the condensate drain pan reaches a predetermined level, and the electronics system and the control sensor are coupled by said electronics system interface connector and said electronics system interface connector to feed said sensor control signal from the control sensor to the electronics system when the control sensor receives said control signal from said control device to operatively integrate said control system into an existing air conditioning system to feed said condensate level signal from said condensate sensor to said control device to feed said control signal from said control device to said control sensor and the electronic system and to feed said sensor control signal to the electronic system without compromising the integrity of the control link between the compressor and the electronics system.
