Communication wiring gure
Outdoor units are in parallel through 3 polar wires. The outdoor and all indoor units are in parallel through 2 non-
polar wires.
Three wiring methods between wired controller and indoor unit:
A.1 to multi (group control): one wired controller controls 2~16 indoors, as shown in above gure, indoor 1~indoor 5:
indoor 5 is wired control master unit, the others are wired control slave units. Wired controller and the master indoor
(directly connected to wired controller) are connected by 3 polar wires; the other indoors and the master indoor are
connected by 2 polar wires.
B. 1 to 1 (one wired controller controls one indoor): as shown in above gure, indoor 6~ indoor 19, indoor and
wired controllers are connected by 3 polar wires.
C. 2 to 1 (two wired controllers control one indoor): as shown in above gure, indoor 20. Either of wired controllers
can be set as master wired controller, and the other is slave wired controller. Master/slave wired controller, and
master wired controller/indoor are connected by 3 polar wires.
When indoor is controlled by remote controller, refer to the "wired control master unit/wired control slave unit/
remote control unit table". A, B, C on signal terminal block do not need wires or connecting with the wired controller.
