8.1 Capacity Settings
8. On-site Configuration
Set up the PCB DIP switch on the indoor electric control box to cater to different
uses. Once the settings are done, make sure you cut off the main power switch
again, and then switch the power on. If the power is not cut off and switched on
again, the settings will not be executed.

Note:
•
The capacity DIP switches have been configured before delivery. Only
a professional maintenance personnel should change these settings.
• Once the centralized control function for the indoor unit has been
completed on the outdoor unit, the DIP switch on main control panel of
the outdoor unit must be set to auto addressing; otherwise, the indoor
unit in the system are not controlled by the centralized controller.
8.2 Address Settings
When this indoor unit is connected to the outdoor unit, the outdoor unit
will automatically allocate the address to the indoor unit. Alternatively, you
may use the controller to manually set the address.
The addresses of any two indoor units in the same system cannot be
the same.
The network address and the indoor unit address are the same, and
does not have to be configured separately.
Once the address settings are completed, mark the address of each
indoor unit to facilitate after-sales maintenance.
The centralized control of the indoor unit is completed on the outdoor
unit. For details, refer to the manual on the outdoor unit.
Caution
Caution
• The system can connect up to 64 indoor units (address 0~63) at the
same time. Each indoor unit can only have one address DIP switch in the
system. The addresses of any two indoor units in the same system
cannot be the same. Units that have the same address may malfunction.

7.4 Handling the Electrical Wiring Connection Points

The X1, X2, D1, D2 ports on the sides of the main control board and the
unidirectional communication port (display board side) are for different
types of wired controllers (see Figure 7.10).

Use the connecting wires (accessory 8) to connect the D1, D2 ports.

Once the wiring and connections are done, use tie straps to secure the
wiring properly so that the connection joint cannot be pulled apart by
external force. The connection wiring must be straight out so that the
cover of the electrical box is level and can be closed tightly.

Use professional insulation and sealing materials to seal and protect the
perforated wires. Poor sealing may lead to condensation, and entry of
small animals and insects that may cause short circuits in parts of the
electrical system, causing the system to fail.
