Note: On the master module, the SA8 DIP switch must be set again, the SA1 DIP switch cannot be
further set, and other DIP switches retain the factory settings without special requirements.
Function DIP switches must be set when the ODU is powered off, and then the settings are valid
after the ODU is powered on.
Meanings and setting methods of function DIP switches are as follows:
① Unit Capacity DIP Switch (SA1_capacity)
The unit capacity DIP switch (SA1_capacity) has been set upon factory departure. It is unnecessary
to further set the DIP switch. In addition, users are not allowed to change the DIP switch settings.
Otherwise, the system may work abnormally or even the compressor may be damaged.
② Centralized Control Address DIP Switch (SA2_Addr-CC)
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".
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:
1) The DIP switch must be set on the master unit. Otherwise, the setting is invalid.

settings are used without being
changed. The address DIP switch
is valid only when it is set on the
master unit.
It is better not to use the

This DIP switch should be set
based on actual engineering
conditions, neither over-large nor
over-small. It is unnecessary to
change the factory settings in
outdoor scenarios.
——
A master unit must be set, and
only one master unit can be set in
each refrigerating system. This
DIP switch is mandatory. The
default factory setting is the
master unit status.
