Sub‑Branch Circuit (MB) Controller
CMB-M-MB-SV
Y-Series Light Commercial Indoor model
The Sub‑Branch Circuit (MB) Controller extends the functionality of the CITY MULTI® R2‑Series heat recovery system by distributing refrigerant from a Main Branch Circuit Controller to additional indoor units. Working in conjunction with the Main Branch Circuit Controller’s liquid‑ and gas‑separation technology, the MB Controller enables simultaneous heating and cooling by directing the appropriate refrigerant phase—hot gas for heating or liquid for cooling—to each connected zone through the same two‑pipe network.
