14.2 Breakdown Self Diagnosis Function
14.2.1 About Self Diagnosis
When the air-conditioner is stopped due to malfunction detected by itself, the operation can be restarted using AUTO Switch on the indoor unit. In forced operation, the frequency for compressor and fan speed can not be changed and the signal receiving sound is different. Normal Operation ON: pep Forced Operation ON: pep, pep, pep, pep Stop: pep Note: Refer to the Diagnosis Code Table for the malfunction when forced operation is not available.
Display of Error Code
1. Keeping the CHECK button on the remote controller depressed for 5 seconds, error code ranging fromH11 to H99 can be displayed on the remote controller. 2. The error code is changed and diagnosis signal is transmitted to the indoor unit by pressing the Temp Up button on the remote control. 3. When the malfunction of the air-conditioner matches the error code on the remote control, four beeps can be heard from the indoor unit and the operation indicator will light up. 4. Keep the CHECK button depressed continuously for 5 seconds to cancel the diagnosis function.
