Note: In actual projects, an RS-485 bus may fail to be connected to 8 refrigerant systems or
64 IDUs in full. One SCC-61 may fail to be connected to 48 refrigerant systems or 384 IDUs
in full.
Example 1: 0# refrigerant system has 20 IDUs, 1# refrigerant system has 30 IDUs, and 2#
refrigerant system has 14 IDUs. As the 3 refrigerant systems have a total of 64 IDUs, the
RS-485 bus cannot be connected to additional systems (now there are less than 8 refrigerant
systems);
Example 2: The 8 refrigerant systems have a total of 40 IDUs (5 each for refrigerant systems
0# to 7#). The RS-485 bus cannot be connected to additional systems because it has been
connected to 8 refrigerant systems (now there are less than 64 IDUs).
Note: The addresses of the 8 refrigerant systems under an RS-485 bus must be different.

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 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.
1 Initial Use
1.1 Connection with VRF System
1.2 Language Selection upon Initial Power-on
* 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.

10
1.3 Login
When the centralized controller is powered on for the first time, select the display language of the
centralized controller.
After selecting the language here, you can re-select the interface display language of the
centralized controller through the language option in "Settings".
Select the language and enter the login interface as follows:
Debugging account: admin; debugging password: 123456
Enter the account number and password, and click "Login" to log in to the centralized controller.
*The languages supported by the centralized controller may increase with the product update.
The screenshots in the manual are only for function description, and the actual product shall
prevail.
*You may directly enter the login interface of individual centralized controllers due to factory
random inspection. You can re-select the interface language of the centralized controller
through the language option in "Settings".

11
1.4 Search (Topology)
A device search is required to display the refrigerant systems connected to the centralized controller.
Entry of the Settings interface (upper right corner)
Overview of device status: power-on, power-off,
disconnection, and failure, and statistics on the number of
devices; the list diagram shows general parameters.
Device monitoring: view device status (card form, list form),
managed groups, managed devices, control devices, etc.
Schedule management: View, edit, and modify schedules.
Report export
* The centralized controller must meet the requirements for the following two periods of time before
conducting "Device search"
Time 1: Time taken to wait for the VRF refrigerant system to run properly (about 15 minutes,
depending on the actual refrigerant system).
When the refrigerant system is powered on, system detection will take some time. During
this period, the centralized controller may obtain incorrect information about the refrigerant
system. If you conduct "Device search" at this moment, the information about the
refrigerant system obtained by the centralized controller will be incorrect (model
identification failure, improper set temperature range, and insufficient VRF units, etc.).
Time 2: time of communication between the centralized controller and VRFs (depending on the
number of connected refrigerant systems, about 5 minutes).
It takes more than 5 minutes for the centralized controller to connect with the properly
running VRF system. If you conduct a "Device search" before this, the information about
the refrigerant system obtained by the centralized controller will be abnormal (model
identification failure, improper set temperature range, and insufficient VRF units, etc.).
Steps: Power on the centralized controller 15 minutes after the communication cables are
connected and the VRF system is powered on. Wait 5 minutes, and search for the device.

12
Click the "Setting" function icon in the upper right corner to enter the "Setting" interface, as
shown in the figure below:
Click "Device search" in the left menu and "Auto topology" in the right area. The centralized controller
will start to obtain information about the refrigerant system connected to the centralized controller and
automatically construct the topological relationship. After this, the interface will appear as follows:
Refri. system Refrigerant system address, automatically generated after search, unmodifiable
Device address, automatically generated after search, unmodifiable
IDU: 00-63, ODU: 96-99 (master unit 96, slave units 1-3 correspond
to 97-99, respectively)
Device type (IDU or ODU), automatically generated after search, unmodifiable
Power of IDU fan, modifiable
Power of IDU auxiliary heater, modifiable
