Wiring instructions:
(1) When one wired controller controls multiple indoor units simultaneously, the wired controller
can connect to any one indoor unit, but the connected indoor unit must be the same series
indoor unit. The total quantity of indoor unit controlled by wired controller can't exceed 16
sets, and the connected indoor unit must be within the same indoor unit's network.
(2) When two wired controllers control one indoor unit, the addresses of those two wired
controllers should be different. Please refer to 3.2.3 parameter setting.

(3) When two wired controllers control multiple indoor units, wired controller can connected
to any one indoor unit, while the connected indoor unit should be the same series indoor
unit. The addresses of those two wired controllers should be different. Please refer to
3.2.3 parameter setting. The total quantity of indoor unit controlled by wired controller can't
be more than 16 sets and all connected indoor units must be within the same indoor unit
network.
(4) When one (or two) wired controller(s) control(s) multiple indoor units at the same time, the
controlled indoor unit's setting should be the same.
(5) Wiring of wired controller and indoor unit network must be according to one of the four
wiring method as shown in g 3.3-3.6. As for the connection method shown in g 3.4 and
3.6, there should be only one master wired controller (address is 01) and one slave wired
controller (address 02). The quantity of wired controller can't exceed two.
