Air conditioning control board composition


The air conditioner control board consists of 4 parts, the power circuit, the three components of the CPU, the input part circuit and the output part load. The output part load has the following 5 parts, indicator light, buzzer, stepper motor, indoor fan and relay.

3 main relays:

1. Compressor relay:

Controls the running and stopping of the compressor. In cooling mode, the compressor is controlled by 3min continuous circuit protection, evaporator low temperature protection, voltage detection, overcurrent protection and other circuits. In heating mode, the compressor has 3min continuous circuit protection, evaporator over-temperature protection, voltage detection, over-current protection and other circuit controls.

2. Outdoor fan coil relay:

Controls the running and stopping of the outdoor fan, and the protection circuit is the same as the compressor.

3. Four-way valve coil relay:

Control the operation and stop of the four-way valve coil. In cooling mode, no power supply, stop working.

Air conditioning control boards are suitable for air conditioners in many places, such as common shopping malls, restaurants, households and other places use our control boards, we support OEM and customized services.
