POINT 3
When the central control is performed for indoor units of twin/triple control in a group control, it may be required
to change the group address. (Adaptor is attached to the header 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 setup, which
unit will become the header unit is indefinite. Therefore if the unit attached with adaptor would not
become the header indoor unit, a central control is unavailable.
