6.2 IDENTIFY ALL POSSIBLE PCB FAULT CODES

P1: Anti icing protection. When the protection is activated, the compressor will be off while the fan motor is on with high speed, and the Turbo indicator will be on with the LED displaying P1. After the Anti-icing function is completed, the unit will restore operation in the previous mode.

P2: Water full protection. When the water tank is full , the compressor and fan motor will shut down and the water full indicator will flash with LED displaying P2. Under this situation, all buttons are deactivated. After the water is removed, the unit will restore operating at the previous setting.

E1: Humidity sensor failure. When the output voltage of sensor is lower than 0.5V or higher than 4.95V, the unit will alarm and the LED displays E1. After the defect is cleared, the unit will not work until the power to the unit is re-stored. E2: Temperature sensor failure. When the output voltage of sensor is lower than 0.5V or higher than 4.95V, the unit will alarm and the LED displays E2. After the defect is cleared, the unit will not work until the power to the unit is re-stored.

6.3TROUBLE SHOOTING
