Step 2: connect the Patch panel of ODU to Main board of IDU.

Notice: There are two connector (CN16) on each indoor unit, they have same function, so you can connect either one to outdoor unit, and the other one is connected to the next indoor unit.

Step -3: Peel the skin of communication wire between ODU and IDU to bare the twin core, then use one communication wiring to connect the ZJ301-W to ODU and IDU, which will be done like this-one end of the wiring is connected the communication module (COM 1), the other end is welding to the communication wire between IDU and ODU.

One end is connected to ZJ301-W The other end is connected to the communication wire between IDU and ODU

Installation procedure Installation procedure

Notice: when you welding the communication wire, please differentiate the A and B terminals, “A” wire need to be welded with “A” wire, “B” wire need to be welded with “B” wire. Do not differentiate the wire only according to color. Once you find the connection is not correct, please exchange them.

The wire is B wire, but not all the yellow wire is B wire.

The wire is A wire, but not all the brown wire is A wire.

Step-4: Connect the main board of indoor unit (either CN16) one by one.

Then set the different address by DIP switch.

The centralized control system is finished.
