The function DIP switches must be set when the outdoor unit is powered off. A DIP switch setting

takes effect after the unit is re-powered on.
The master module SA8 DIP switch must be reset in the project. SA1 DIP switch cannot be

changed. The default settings of other DIP switches do not need to be changed if there are no
special requirements.
4.1.1 Unit Capacity DIP Switch (SA1_capacity)
This DIP switch is set by the factory before shipment, and cannot be changed. Otherwise, the system
will work abnormally and even damage the compressor.
4.1.2 Address DIP Switch for Centralized Control (SA2_Addr-CC)
This DIP switch indicates the address for centralized control of different refrigerating systems. It is
set to 0000× by default.
If centralized control is not required between multiple refrigerating systems, keep the default setting
of this DIP switch.
If centralized control is required between multiple refrigerating systems, set as follows:
(1) Be sure to set the DIP switch on the master unit.
(2) Setting this DIP switch on non-master units in a refrigerating system is invalid and
unnecessary.
(3) Be sure to set the address DIP switch for centralized control (SA2_Addr-CC) on the master
unit of a refrigerating system to "0000x". Then, this system is the main system.
(4) Set the address DIP switch for centralized control (SA2_Addr-CC) on the master units of other
refrigerating systems as follows:

Remarks
The DIP switch is set by the
factory and cannot be changed.
The code is used only for
centralized control. Otherwise,
keep the default setting. This
address can be set only on the
master unit.
Exactly one module must be
configured as the master
module in a refrigerating
system. The master module
status is set by default.
