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.
NOTE
• 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 12-4 “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.
