address
(Note 2)
Note 2:
• Set the address by code when connecting the centralized controller or gateway or charge system.
• Address of centralized controller = communication address + 0 or +64.
SW03_ 2=OFF, address of centralized controller =communication address+0=communication
address
SW03_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, it is required to use code for address setting. Set SW03_1 =0N and SW03_
2=OFF; SW03_3, SW03_ 4, SW03_5, SW03_6, SW03_7 and SW03_8 are address codes which are
set according to actual addresses.
