Communication wiring figure
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
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.
power source: 3N~, 380-400V, 50/60Hz
outdoor
power source: 1PH, 220-230V~, 50Hz
indoor 1
(wall mounted unit)
power source: 1PH, 220-230V~, 50Hz
indoor 2
(wall mounted unit)
power source: 1PH, 220-230V~, 50Hz
indoor 3
(non wall mounted unit)
power source: 1PH, 220-230V~, 50/60Hz
power source: 1PH, 220-230V~, 50Hz
