SYSTEM DESIGN
2. M-NET CONTROL
2-4-3-4. ME remote controller, Single-refrigerant-system, No system controller
2. Address should be set to Indoor units, system controller and ME remote controllers.
3. M-NET power is supplied by the Heat source 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:
1. Heat source 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.
