Note *:
• Set the address by code when connecting the centralized controller or gateway or charge system.
• Address of centralized controller=communication address+0 or+64.
SW3_ 2=OFF, address of centralized controller=communication address+0=communication address
SW3_ 2=ON, address of centralized controller=communication address+64 (applies when centralized controller is used
and there are more than 64 indoor units)
• To use with 0010451181A in use, it is required to use code for address setting. Set SW3_1=0N
and SW3_ 2=OFF; SW3_3, SW3_ 4, SW3_5, SW3_6, SW3_7 and SW3_ 8 are address codes which are set according
to actual address.
