Error code
AJ
LED indications The table below shows the LED indications.
Error generation The error is generated when the following conditions are fulfilled:
Causes The possible causes are:
■
Malfunctioning capacity setting adapter connection
■
Malfunctioning indoor unit PCB.
Capacity setting
adapter The capacity is set in the PCB’s memory IC. A capacity setting adapter that matches the capacity of
the unit is required in the following case:
In case the indoor PCB installed at the factory is for some reason changed at the installation site, the
capacity will not be contained in the replacement PCB. To set the correct capacity for the PCB you
have to connect a capacity setting adapter with the correct capacity setting to the PCB. The capacity
setting for the PCB will become the capacity setting of the adapter because the capacity setting
adapter has priority.
