1.2 Installation instructions

Installation instructions

1) Connect 220VAC power to the L、N terminals of the centralized controller directly.

2) Do not lay the signal wire and the power wire of the centralized controller in the same power
wire pipe, there should be 300~500mm distance between two pipes.

3) The signal wire of centralized controller should not exceed 1200m.

4) No intermediate joint is allowed for the shielded cable. If joints are inevitable, crimp it with the
terminal block.

5) After the centralized controller is connected, do not use megohmmeter to inspect the insulation
of the signal cable.

6) Wiring mode of the centralized controller and the network interface:
The communication port between the centralized controller and the network interface of the air
conditioner is polarity-sensitive.The X,Y and E at both sides should correspond properly. Dot
not cross-connect the signal wires,the same to the RS485-RS232 of the centralized controller.

Note

The RS485-to-RS232 module and the wires in the wiring diagram are used when the network
system needs to connect with the computer only. One computer can connect with 16 centralized
controllers at most, Namely the maximum of indoor units is 16X64=1024 ,that a network system
can connect. The centralized controllers can be distinguished by address code,which setting range
is 0 to 15. No duplicate addresses is allowed in a same network.
