2-4-3-3. MA remote controller, Multi-refrigerant-system, System Controller at TB7 side, Booster for long M-NET wiring
*3 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".
2. Address should be set to Indoor units, LOSSNAY and central controller.
3. 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".
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.
