6.4 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 6.10).
Use the connecting wires (accessories) to connect the D1/D2 terminals.
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.
2) For a unidirectional communication mode:
w Use 1 wired controller to control 1 indoor unit (see Figure 6.9).

• 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.
• 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.

7.2 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.
w The addresses of any two indoor units in the same system cannot be the
same.
w The network address and the indoor unit address are the same, and does
not have to be configured separately.
w Once the address settings are completed, mark the address of each indoor
unit to facilitate after-sales maintenance.
w The centralized control of the indoor unit is completed on the outdoor unit.
For details, refer to the manual on the outdoor unit.
