GFRWKCEX PCB05-457-V03 1878005.C ，Compatible For Hisense， AT242CB Air Conditioner Outdoor Unit Inverter Drive Control Board(No Cooling Block)

Drive the compressor to operate: By accurately regulating the output current, the compressor is driven to run at high speed or low speed to ensure that the air conditioner is cooled or heated on demand, and effectively reduce energy consumption while meeting the needs of indoor temperature regulation. Adjust the speed of the fan: adjust the speed of the fan in real time according to the operating status of the air conditioner. In the early stage of refrigeration, the speed is increased to enhance heat dissipation, and the speed is reduced after stable operation to achieve the effect of energy saving and noise reduction. Monitoring system pressure: Sensors are used to collect pressure data within the air conditioning system, and once the pressure exceeds a safe threshold, a protection mechanism is triggered immediately to prevent damage to the equipment due to abnormal pressure. Manage the reversing of the four-way valve: When switching between cooling and heating modes, the motherboard will issue precise commands to control the reversing of the four-way valve to ensure the correct flow of refrigerant and ensure the stable operation of the air conditioner.
