1.2.3 Connection Method
There are three methods to connect centralized controller with the air conditioning
system:
E-Smart Zone Controller

Method 2: Connect with ODU network
Fig.1.5 Centralized Controller Connected with ODU Network
E-Smart Zone Controller

Method 3: Connect with heat recovery mode converter network
Fig. 1.6 Centralized Controller Connected with Heat Recovery Mode Converter
Network
Wiring Instructions:
（1）The smart centralized controller is applicable to multi VRF units, connectable
with IDU network, ODU network or mode converter network. One centralized
controller can control up to 16 sets of outdoor unit system and up to 32 sets of
indoor unit.
（2）If the centralized controller is to be connected with the IDU network, connect
according to Fig.1.4. 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 wires. When the controller is
connected with the terminal unit of IDU network, a matching resistance needs
to be added with the communication wires at the G1 and G2 ports.
（3）If the centralized controller is to be connected with the ODU network,
connect according to Fig.1.5. The centralized controller can only be
connected with the terminal system of the ODU network. A matching
resistance needs to be added with the communication cords at the G1 and G2
E-Smart Zone Controller

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 heat recovery network,
connect according to Fig. 1.6. The method 2 is also applicable to centralized
controller connected with the heat recovery network.
If the centralized controller is to be connected with the ODU network, set the ODU
centralized control address DIP switch according to the following methods:
1) The DIP switch must be set on the master outdoor 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
on a non-master unit is invalid, and it is unnecessary to change the settings;
3) The centralized control address DIP switch on the master outdoor unit of a
refrigerating system must be set to “00000”, and this system is the master
mode system;
4) The centralized control address DIP switch on the master unit of other
refrigerating systems must be set as follows:

1.3 Installation Procedures
Fig.1.7 Installation Diagram
Fig.1.7 shows the simple installation procedures of centralized controller. Please
pay attention to the following matters:
（1）Before installation, first cut off the power supply of indoor unit. The power
must be cut off during the whole installation process.
（2）During the installation, be careful not to damage the touch screen.
（3）Before installation, please make the following preparations:
In case that the centralized controller is installed on wall, dig a installation hole
with the size of 86mm×88.5mm×46.5mm on the wall.
（4）In step ①, pull out the power core and communication wire, and then lead
them separately from the wire orifice of the electric box rear cover. Never lead
the cords through the same orifice.
（5）In step ②, secure the wiring box on the wall.
（6）In step ⑥, pull out the wire connecting the touch screen and controller’s rear
cover. Then put the touch screen on a safe place.
（7）In step ⑦, connect the communication wire to G1,G2 terminals, and connect
the neutral wire and live wire to the L, N terminal; connect the ground wire to
E-Smart Zone Controller
9
position on the electric box rear cover. Secure it with screw M4x12.
（8）In step ⑧, locate the controller’s rear cover onto the wiring box with screw
ST4.2X9.5MC.
（9）In step ⑨, connect the wire between touch screen and controller’s rear
cover.
