Installation Procedure

Wiring connections of wired controller
There are three methods to
A.One wired controller can control max. up to 16 sets of indoor units. In this case, 3 pieces of polar wire must connect
the wired controller and the master unit (the indoor unit connected with wired controller directly), the others connect with
the master unit through 2 pieces of polar wire.
B. One wired controller controls one indoor unit. The indoor unit connects with the wired controller through 3 pieces
of polar wire.
C. Two wired controllers control one indoor unit. The wired controller connected with indoor unit is called master one,
the other is called slave one. Master wired controller and indoor unit; master and slave wired controllers are all connected
through 3 pieces of polar wire.
Note:
The method A needs to set the PCB function switch. The method C needs to set the controller function switch.

Communication wiring

The wired controller is equipped with special communication wiring in the accessories. 3-core terminal (1-white 2-yellow
3-red) is connected with the terminal A, B, C of wired controller respectively.
The communication wiring is 4 meter long. If the actual length is more than it, please distribute wiring according to below
table:
Communication wiring length(m)
< 100
100 and <200
200 and <300
300 and <400
400 and <600
*One side of the shielded sheet of communication wire must be earthed.
