9.2.2 Open or short circuit of temperature sensor diagnosis and solution.

9.2.3 EEPROM parameter error diagnosis and solution

9.2.4 Zero crossing detection error

When such failure occurs, the main control board must have fault.

Replace indoor PCB

hut off the power supply and turn on it 5s later

The problem comes out again

Is the EEPROM chip plugged in indoor PCB well?

Correct the connection

Replace the main PCB of indoor unit

Yes

Replace outdoor PCB

Yes

Check the connections between
