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 unit 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.
