The GREE 300002000309 Main Control Board is an electronic controller that is used to synchronize the actions of the system and control the activity of components in air-conditioning equipment. It operates by means of integrated circuits and microprocessor logic, which take inputs of temperature sensors, pressure switches, and thermostat inputs, and sends commands to compressors, fan motors, and valves when used in HVAC systems. The board is attached to the equipment control compartment, wiring harnesses are attached to specific terminals and power supply connections are provided to support the control circuitry. Constant signal processing controls cooling cycles, oversees operating conditions, and coordinates connected components.
