Electric wiring and the application
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 can control 2~19 indoors. As shown in above
figure, 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) is
connected by 3 polar wires; the other indoors and the master indoors are connected by 2 or 3
polar wires, AC indoors wired "B" "C" polar wires, DC indoors wired "A" "B" "C" polar wires*.
B. 1 to 1 (one wired controller controls one indoor): as shown in above gure, indoor 6~ indoor
18, indoor and wired controller are connected by 3 polar wires.
C. 2 to 1 (two wired controller controls one indoor): as shown in above gure, indoor 19. Either
of wired controllers can be set as master wired controller, and the other is slave wired controller.
Master/slave wired controller, and master/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 need not wires and
not connect the wired controller.
