*1 System controller should connect to TB7 at Outdoor and use power supply unit together in Multi-Refrigerant-System.
For AG-150A, 24V DC should be used with the PAC-SC51KUA.
*2 When multiple system controllers are connected in the system, set the controller with more functions than others as a "main"
controller and others as "sub".
Make the setting to only one of the system controllers for "prohibition of operation from local remote controller".
NOTE:
1. Outdoor units OC, OS1 and OS2 in one refrigerant circuit system are automatically detected.
OC, OS1 and OS2 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 remote controller 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".
