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. 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 heat source unit address or the auxiliary heat source unit address to "100," set the rotary switches to "50."
*3. To set the M-NET 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. The heat source units in the same refrigerant circuit are automatically designated as OC, and OS. They are designated as
OC, and OS in the descending order of capacity (ascending order of address if the capacities are the same).
*6. No address settings are required for units in a system with a single heat source unit (with some exceptions).
Address setting is required if a sub BC controller is connected.

Assign the smallest address to the main indoor unit in the
group, and assign sequential address numbers to the rest
of the indoor units in the same group.
In an R2 system with a sub BC controller, make the set-
tings for the indoor units in the following order.
(i) Indoor unit to be connected to the main BC controller
(ii) Indoor unit to be connected to sub BC controller 1
(iii) Indoor unit to be connected to sub BC controller 2
Make the settings for the indoor units in the way that the
formula "(i) < (ii) < (iii)" is true.
