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 2:
indoor 2 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 figure, indoor 3~ indoor 4, 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 6. 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.
Power wiring figure
outdoor
AWAU-YCV150-180-H13
power source: 3N~, 380-400V, 50/60Hz
indoor 1
(wall mounted unit)
power source: 1PH, 220-230V~, 50Hz
Indoor and outdoor use their individual power source. All indoors use one power source. Must install the leakage breaker
and the over current breaker, or electric shock will occur.
