ABSTRACT:
An air conditioning system for a building including an air conditioner, a thermostat for controlling operation of the air conditioner, and alternating current electrical control means including circuitry for effectively maintaining operation of the air conditioner and wherein said system comprises a relay including a switch normally closed in the absence of adverse presence of water, at least one water sensor functioning as a switch in the presence of water, and a triac including first and second terminals and a gate, said triac preventing flow of current to the relay and permitting flow of current when the gate of the triac receives flow of an electrical current. Flow of current from the first terminal to the second terminal of the triac and then to said relay effectively opens said normally closed switch for automatically interrupting the flow of alternating current to the thermostat and shutdown of the air conditioner for preventing damage to the building upon adverse accumulation of water discharged from the air conditioner.
