Not the error code. It’s the status
code for the operation.
Refer to
maintenance
flowchart.
(1) When multiple malfunction occurs, error codes will be displayed in turns (when it detected that AD value of temperature sensor is ≥
250 or ≤5 for consecutive 5s, it will enter into the temperature sensor protection);
(2) Under on status, when there’s temperature sensor malfunction, the compressor stops operation. Under non-heating mode, the
fan operates according to set fan speed; under heating mode, the fan stops operation after blowing residual heat. Under off status,
malfunction won’t be displayed, but it can receive remote control signal and button signal. When there’s above malfunction under off
status, turn on the unit and it will only display the malfunction. The compressor won’t stop operation. Under non-heating mode, the fan
operates according to set fan speed; under heating mode, the fan stops operation.
