2-4 M-NET Address Settings
2-4-1 Address Settings List
1. M-NET Address settings
(1) Address settings table
The need for address settings and the range of address setting depend on the configuration of the system.
*1. If a given address overlaps any of the addresses that are assigned to other units, use a different, unused address within the setting
range.
*2. To set the outdoor unit address or the auxiliary outdoor unit address to "100," set the rotary switches to "50."
*3. To set the ME remote controller address to "200," set the rotary switches to "00."
*4. Some models of indoor units have two or three control boards.
Assign an address to the No.1, No. 2, and No. 3 control boards so that the No. 2 control board address equals the No. 1 control board
address plus 1, and that the No. 3 control board address equals the No. 1 control board address plus 2.
*5. No address settings are required for units in a system with a single outdoor unit (with some exceptions).
Address setting is required if a sub HBC are connected.
