Installation of GMV ODU and IDU
Main board Main board of slave unit PCB of outdoor fan 1 PCB of outdoor fan 2 Patch panel 1 Patch panel 2 Electronic card on ODU There are total six electronic cards on ODU, which has been connected before leaving our factory. GMV-R600W4/Na-M
Main board of slave unit Main board Detail photo for each electronic cards There are two main board for each unit, which have been connected before leaving factory.
PCB of outdoor fan-1 PCB of outdoor fan-2 Slave Patch panel Main Patch panel Detail photo for each electronic cards The PCB of outdoor fan are to control outdoor fan speed. The two pcs of Patch Panel have same function, when indoor units are less than 17 pcs, user can choose either one patch panel.
Detail photo for each electronic cards There are three-digital switch on patch panel, on the main patch panel, the switch shows 100, and on the slave patch panel, the switch shows000. In this way, the centralized controller can recognize that the indoor units are from which patch panel. Slave patch panelMain Patch panel
What do you need to you for ODU? For the ODU, the Main PCB (2 pcs), the Patch panel (2 pcs) and the PCB of outdoor fan (2 pcs) have been connected in factory, so what user need to do is only to connect the power supply to main switch.
The communication diagram between ODU and IDU All the communication wire is two score twisted- pair wire, which is standard part in ODU and IDU package.
Step 1: connect the Centralized controller ZJ7011 and Communication module. Installation procedure
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-WThe other end is connected to the communication wire between IDU and ODU 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.
