Definition principles of code switches:
(A) Definition of SW01:
• SW01_1-4 is used to set indoor address when grouping multiple indoor units connected to single wired controller
YRE16B or YR-E17.
• SW01_5-8 set capacity of the indoor unit (factory set). Must only set when replacing board.
SW01_1 Address of wire
SW01_2 controlled indoor unit
SW01_3 (group address)
SW01_4
SW01_5 Capability of indoor unit
SW01_6
SW01_7
SW01_8
Note : A wired controller can be connected to sixteen ultrathin air-duct indoor units.
(B) Definition and description of SW03
• SW03_1-8 is used to set indoor unit address on system. Set address only if using central controller YCZ-A004.
Leave default if no central controller is used.

SW03_2 Code-set indoor unit
~ address and centralized
SW03_8 controller address
Note:
• Set the address by code when connecting the centralized controller, gateway or control 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)
