GREE 300002000315 Main Control Board

GREE 300002000315 Main Control Board is an electronic controller that is used to synchronize the operations of the system and control the work of components in air-conditioning systems. It operates on integrated circuits and microprocessor logic which are fed signals by temperature sensors, pressure switches and thermostat inputs and feeds compressors, fan motors and valves when used in HVAC systems. The board is mounted in the equipment control compartment with wiring harnesses being connected to the appropriate terminals and power supply connections being used to support system control circuits. The continuous signal processing enables the controller to control cooling cycles, check the operating conditions, and coordinate the connected components.
