Wiring Connections of Wire Controller
Communication wiring
There are three methods to connect wired controller with the indoor units
A. One wired controller can control max. up to 16 sets of indoor units, and 3 pieces of polar wire must connect the
wire controller and the master unit (the indoor unit connected with wire controller directly), the others DC indoor unit
connect with the master unit through 2 pieces of polar wire and AC indoor unit connect with the master unit through
3 pieces of polar wire.
B. One wire controller controls one indoor unit, and the indoor unit connects with the wire 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 wire controllers are all
connected through 3 pieces of polar wire.
Notice: For wired controller connection, please do follow the corresponding indoor unit installation manual's
instruction.
