(1) Basic wiring diagram for group control
This diagram shows when several units (max. 8) are
controlled by a wired controller. In this case, a
wired controller can be connected at any indoor unit.
NOTE
●
R.C. Addresses should be set before turning the power on.
●
Auto. address setting can be executed by the wired controller automatically.
Please refer to section 8 “PCB Setting”.
●
Each successive unit will respond at one-second intervals following the order of the R.C. (S2) address when the remote
controller is operating.
