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 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 polar wires.
B. 1 to 1 (one wired controller controls one indoor) : as shown in above figure, indoor 6~ indoor 19, indoor and
wired controller are connected by 3 polar wires.
C. 2 to 1 (two wired controller controls one indoor) : as shown in above figure, 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.
