2. 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. Address setting is not required for a City Multi system that consists of a single refrigerant circuit (with some exceptions).
*2. To set the M-NET remote controller address to "200", set the rotary switches to "00".
*3. To set the outdoor unit address to "100," set the rotary switches to "50."
*4. Some indoor units have 2 or 3 controller boards that require address settings.
No. 2 controller board address must be equal to the sum of the No. 1 controller board address and 1, and the No.3
controller board address must equal to the No. 1 controller address and 2.
*5. The outdoor units in the same refrigerant circuit are automatically designated as OC, OS1, and OS2 in the order of
capacity from large to small (if two or more units have the same capacity, in the order of address from small to large).
