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 an address is a duplicate of an indoor unit or outdoor unit of another refrigerant circuit, set another address, which
is within the setting range and is not in use.
*2. To set the outdoor unit address to "100," set the switches to "50."
*3. For the addresses of the outdoor units to be used together, set consecutive numbers in order from the one with the
highest capacity.
Furthermore, for the outdoor units of the same refrigerant circuit, the order of OC and OS becomes from the one with
the highest capacity. (If the capacity is the same, the order is from the one with the lowest address.)
