1. M-NET power is supplied by the Outdoor unit at TB3, while Indoor unit and ME RC consume the M-NET power for transmission
use. The power balance is needed to consider for long M-NET wiring. Details refer to
2-3 "System configuration restrictions".
NOTE:
2. Indoor units should be set with a branch number.
3. Assign an address to each of the sub BC controllers which equals the sum of the smallest address of the indoor
units that are connected to each sub BC controller and 50.
When the address assigned to sub BC controller overlaps those of any other units including outdoor units (OC/OS) or main BC controller,
sub BC controller will be given priority to have the address.

• Indoor units should be set with a branch number.
• BC (main) address = O/U a 1
• BC (sub) address = Lowest address within the indoor units connected to the BC controller (sub) + 50
• If applicable, set the sub BC controllers in an PURY system in the following order:
(1) Indoor unit to be connected to the BC controller (Main)
(2) Indoor unit to be connected to the BC controller (No.1 Sub)
(3) Indoor unit to be connected to the BC controller (No.2 Sub)
Set the address so that (1)<(2)<(3)
