Error generation The error is generated when the following conditions are fulfilled:
Causes The possible causes are:
Q
Malfunctioning capacity setting adaptor connection
Q
Malfunctioning indoor unit PCB.
Capacity setting
adaptor The capacity is set in the PCB’s memory IC. A capacity setting adaptor 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 adaptor with the correct capacity setting to the PCB. The capacity
setting for the PCB will become the capacity setting of the adaptor because the capacity setting
adaptor has priority.
