Main BC Controller
CMB-M-MA-SV
Y-Series Light Commercial Indoor model
The Main Branch Circuit Controller is the core control component of the CITY MULTI® R2 Series heat recovery system. It houses the refrigerant liquid and gas separation technology that enables simultaneous heating and cooling by directing hot gas for heating and liquid refrigerant for cooling to connected indoor units through a single two-pipe network. By precisely managing refrigerant flow between the outdoor unit and connected branch circuits, the Main Branch Circuit Controller supports efficient system operation and scalable zoning for complex multi-zone applications
