Multi-VRF Centralized Controller

① The smart centralized controller is applicable to multi VRF units,

connectable with network of indoor units or the network of outdoor units or mode converter network. One centralized controller can control up to 16 sets of outdoor system and up to 32 sets of indoor unit.

② If the centralized controller is to be connected with the network of indoor

units, connect according to fig.3.4. The controller can connect with any one indoor unit in series, that is, connect the controller’s G1 and G2 ports

with the D1 and D2 ports correspondingly with communication cords. When the controller is connected with the terminal unit of indoor network, a matching resistance needs to be added with the communication cords at the G1 and G2 ports.

③ If the centralized controller is to be connected with the network of outdoor

units, connect according to fig.3.5. The centralized controller can only be connected with the terminal system of the outdoor network. A matching resistance needs to be added with the communication cords at the G1 and G2 ports.

④ The centralized control address DIP switch (SA2_Addr-CC) indicates the

centralized control address required when different refrigerating systems are controlled in a centralized manner. The default factory setting is "00000".

⑤ If the centralized controller is to be connected with the network of heat

recollection, connect according to Fig. 3.6. The method 2 is also applicable to centralized controller switching in heat recollection network.

If the centralized controller is to be connected with the network of outdoor units,

set the DIP switch according to the following methods:

1) The DIP switch must be set on the master unit and set the Master Unit Setting DIP Switch(SA8) to "00".Otherwise, the setting is invalid.

2) On the same refrigerating system, the centralized control address DIP switch (SA2_Addr-CC) on a non-master unit is invalid, and it is unnecessary to change the settings.

3) The centralized control address DIP switch (SA2_Addr- CC) on the master unit of a refrigerating system must be set to “0000/”, and this system is the master system.

4) The centralized control address DIP switch (SA2_Addr- CC) on the master unit of other refrigerating systems must be set as follows:

Note: The centralized control address switch of DIP5 invalidation

5) The centralized control address DIP switch (SA2_Addr- CC) cannot be the same between different refrigerating systems. Otherwise, address conflicts may occur and the unit cannot run properly.

6) If the address conflict occurs, it will popup the address conflict page. Note:There are three ways to solve address conflict. 1: Enter into an unoccupied address by manually for the conflict address, the address conflict can be solved after it set up success. 2: Press and hold the “Save” button for 5 seconds on the address conflict page, select reset all the IDU’s address in the system, after entering the engineering password, system will reassign all the address. 3: On the master unit of master system, press “SW3” to enter the to-be-selected status of function settings, press “SW1 (UP)” or “SW2 (DOWN)” to select the function of “n5 ”, press “SW7” to enter “n5 ” function settings, press “SW7” again to send the project number offset command.

on the wall according to fig.3.8.

2) In case that the centralized controller is installed inside the control cabinet, dig 4 installation holes on the surface of the control cabinet according to fig.3.9.

(4) In step (1), pull out the power core and communication cord, and then lead

them separately from the wire orifice of the electric box rear cover. Never lead the cords through a same orifice.

(5) In step (2), locate the electric box rear cover to the installation holes of the

wall with screw ST4.2×16 FA.

(6) In step (6), pull out the wire connecting the touch screen and controller’s

rear cover. Put the touch screen on a safe place.

(7) In step (7), connect the communication cords to G1, G2 terminals, and

connect the neutral wire and live wire to the N, L terminal; connect the ground wire to position on the electric box rear cover. Secure it with

screw M4×12.

(8) In step (8), locate the controller’s rear cover onto the electric box rear

cover with screw ST4.2×9.5 TC.

(9) In step (9), connect the wire between touch screen and controller’s rear

cover.
