Product Intruduction 
The air conditioner circuit board contains 4 parts, power circuit, three elements of CPU, input part circuit and output part load.

Product Function

The input circuit has following 6 signals
1. Data signal: Its main component is memory and the corresponding circuit is a memory circuit. Its role is to provide the CPU with necessary data information at runtime.
2. Emergency switch signal: Its main component is key switch and the corresponding circuit is an emergency switch circuit. Its function is that you can use the air conditioner when there is no remote control.
3. Remote control signal: Its main component is receiver and the corresponding circuit is the receiver circuit. Its role is to process the infrared signal sent by the remote controller and send it to the CPU.
4. Temperature signal: Its main component is ring temperature sensor and tube temperature sensor, and the corresponding circuit is the sensor circuit. Its function is to send the voltage signal representing the change of room temperature and evaporator temperature to the CPU.
5. Zero crossing signal: Its main component is zero-crossing detection transistor, and the corresponding circuit is a zero-crossing detection circuit. Its function is to provide a zero-crossing signal, so that the CPU can control SCR to meet at or near zero, and meet nearby and PG motor can run normally.
6. Hall feedback signal: Its main components hall elements are integrated inside the PG motor, connected to the CPU through the socket, and the corresponding circuit is the Hall feedback circuit. Its function is to provide the actual speed of the PG motor for the CPU.
