3.2.3 Connection Method Of Multi-VRF(CAN Network)

There are three methods to connect centralized controller with the air conditioning system.

Centralized Controller

Page 8

Method 1: Connect with indoor network

Figure 3-4 Centralized Controller Connected with Indoor Network

Method 2: Connect with outdoor network

Figure 3-5 Centralized Controller Connected with Outdoor Network

Centralized Controller

Page 9

Method 3: Connect with heat recollection mode converter Network

Figure 3-6 Centralized Controller Connected with Heat Recollection Mode Converter

Network

Wiring Instructions: (1)

The centralized controller is applicable to multi VRF units, connectable with network of indoor units or the network of outdoor units. One centralized controller can control up to 16 sets of outdoor system and up to 255 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:

Centralized Controller

Page 10

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.

Centralized Controller

Page 11

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.

3.2.4 Connection Method of Umatch Unit(Modbus network)

The centralized controller Connect with Umatch Unit（Modbus network）according to the below.

Figure 3-7 Centralized Controller Connected with Umatch Unit

Wiring Instructions: (1)

The centralized controller is applicable to Umatch units, One centralized controller can control up to 36 Umatch units.

(2)If the centralized controller is to be connected with Umatch units, connect

according to fig.3–7. The controller must connect with terminal unit of Umatch unit . connect the controller’s A3 and B3 ports with the A and B ports correspondingly with communication cords.a matching resistance needs to be added with the communication cords at the A3 and B3 ports

(3)The indoor unit address must be set within the range from 1 to 36, and different

from each other. Identicle addresses will lead to communication failure. Below is the address setting method:

1) Under OFF status, press “Function” and “Mode” on the wired controller simultaneously for 5S to enter the address setting. Then the display panel will show its own address number on the temperature display zone. Adjust the number by pressing the “Up” and “Down” buttons.

Centralized Controller

Page 12

2) When setting is over, press “OK/Cancel” or “Swing/Enter” to save the setting and exit. Under the setting status, if no action is taken within 20 seconds, system will exit from the setting and return to the display mode of OFF status. Setting can’t be saved in this case.

(4)Communication method of umatch units must be long-distance monitoring mode,

else can not communicate with centralized controller, set the way as follows.

1) Under OFF status, press “Function” and “Timer” on the wired controller simultaneously for 5S to enter the setting of long-distance monitor. Adjust by pressing the “Up” and “Down” buttons.

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.3–10.

(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 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.

Centralized Controller

Page 14

(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.
