*1 System controller should connect to TB7 at Outdoor and use power supply unit together in Multi-Refrigerant-System.
*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. 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".
