Do not turn the power supply to the equipment OFF before reading the fault codes, doing so will clear the diagnostic memory. Current fault codes are displayed automatically on a hard wired remote controller or by depressing the “check” button on infra-red controllers. Caution must be taken when removing any access covers as high voltage may be present.

Please enter the fault code, including any sub-codes. When entering sub-codes, enter the standard fault code then a full stop, the the sub-codes.

E.g. P05.0111
