*1 System controller should connect to TB7 at Outdoor and use power supply unit together in Multi-Refrigerant-System.
For AG-150A-A, 24VDC should be used with the PAC-SC51KUA. For AE-200A, AE-50A, and EW-50A the power supply unit PAC-SC51KUA is unused.
NOTE:
1. Outdoor units OC and OS in one refrigerant circuit system are automatically detected.
OC and OS are ranked in descending order of capacity. If units are the same capacity, they are ranked in ascending order of their address.
2. M-NET power is supplied by the Outdoor unit at TB3, while Indoor unit and ME R/C consume the M-NET power for transmission
use. The power balance is needed to consider for long M-NET wiring. Details refer to 11-3. "System configuration restrictions".
3. Indoor units should be set with a branch number.
4. 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.

NOTE
• Indoor units should be set with a branch number.
• BC (main) address = O/U address + 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)
