There are three methods to connection wire controller and 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 connect
with the master unit through 2 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 wire controller connected with indoor unit is called master one,
the other is called slave one. Master wire controller and indoor unit; master and slave wire controllers are all
connected through 3 pieces of polar wire.
Note: For some slim duct type and middle ESP duct type (The PCB spare part number of which is 0151800175B or
0151800173), there will be a different wiring method, please refer to the service manul to get the wiring details.
