1 Initial Use

Before using the unit for the first time, read the following content carefully and operate and set the

centralized controller according to the prompts, so that you can fully understand how to use the

basic functions of the centralized controller and correctly configure related settings.

* The functions supported by the centralized controller (including function details) will be

increased with product updates. Due to the update cycle and other reasons, some function

details in the manual may be inconsistent with the actual product, such as interface

screenshots, display parameter names, etc., and the actual product shall prevail.

The centralized controller has six RS-485 bus interfaces (X1/Y1/E, X2/Y2/E, X3/Y3/E, X4/Y4/E,

X5/Y5/E, X6/Y6/E). Each RS-485 bus interface can be connected to eight refrigerant systems (up to

64 IDUs). When multiple refrigerant systems are connected to one RS-485 bus interface, connect the

X port of the master ODU of multiple refrigerant systems in series and connect it to the X port of the

centralized controller; connect the Y port of the master ODU of multiple refrigerant systems in series

and connect it to the Y port of the centralized controller; then connect the E port of the master ODU

of multiple refrigerant systems in series and connect it to the E port of the centralized controller.

After the connection between the VRF unit and the centralized controller is completed (X/Y/E wiring)

and the VRF unit is operating normally, turn on the power of the centralized controller to enter the

software debugging mode.
