(2) Basic wiring diagram for group control
This diagram shows when several units (max. 8) are
controlled by a remote controller. In this case, a
remote controller can be connected at any indoor unit.
● R.C. Address should be set before turning the power on.
● Auto. address setting can be executed by a remote controller automatically.
Please refer to “Automatic Address Setting Method”.
● Each successive unit will respond at one-second intervals following the order of the R.C. address when the
remote controller is operated.
