pipeline connected with the
engineering unit, to guarantee
normal operation of the unit.
This DIP swith should be set
based on actual engineering
conditions, neither over-large
nor over-small. It is unnecessary
to change the factory settings in
outdoor locations.

Instruction:
1) Centralized control address DIP switch (SA2_Addr-CC)
The centralized control address DIP switch (SA2_Addr-CC) indicates the centralized control
address required when differenc refrigerating systems are controlled in a centralized manner. The
default factory setting is ―00000‖. If it is not required to use centralized control between multiple
refrigerating systems, this DIP switch can retain the factory settings without being changed.
If it is required to use centralized control between multiple refrigerating systems, set the DIP
switch according to the following methods:
A. The DIP switch must be set on the master unit. Otherwise, the setting is invalid;
B. The centralized control address DIP switch (SA2_Addr-CC) on the master unit of a
refrigerating system must be set to ―00000‖, and this system is the master system.
C. The centralized control address DIP switch (SA2_Addr-CC) on the master unit of other
refrigerating systems must be set as follows:
