POINT 3
When the central control is performed for indoor units of twin control in a group control, it may be required
to change the group address. (Adapter is attached to the header indoor unit.)
Reason : The central control device communicates with individual indoor unit, header indoor unit of the
group control, and header indoor unit of twin control. However, as the address is automatically
set up, which unit will become the header unit is indefinite. Therefore if the unit attached with
adapter would not become the header indoor unit, a central control is unavailable.
