1. Mount the embedded
junction box
Mount the embedded junction box
within the wall. Ensure that the
outer surface ③ of the embedded
junction box is level with the wall
surface.
Product Description
SCC-61 touch screen centralized controller [hereinafter referred to as "centralized controller"]
provides centralized management functions for VRF units.
It is compatible with all SDV6 series units, that is, SDV6 ODUs and SDV6 IDUs.
The product supports 6 RS-485 buses, and each RS-485 bus can be connected to up to 8
SDV6 refrigerant systems (8 refrigerant systems can have a maximum of 64 IDUs), that is, a
centralized controller can be connected to a maximum of 48 refrigerant systems (48 refrigerant
systems can have a maximum of 384 IDUs).
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.

2. Install metal parts
Make sure the hooks of the metal
parts face upwards. Use 4 screws ④
provided as accessories to secure it
on the installation base.
NOTE
Special note: Make sure you exert
appropriate force to secure the metal
parts with the screws. Excessive force
may cause deformation of the four
screw holes for the metal parts,
making it harder to mount the metal
mounting board.

3. Install SCC-61
Once the connections are
done, place the main unit
vertically on the installation
base. You will feel a magnetic
force at this point. Exert force
downwards to mount it on the
metal part.
