The Branch Controller allows for simultaneous cooling and heating across a single R2 system using only two pipes.

2 pipe heat recovery

In many ways, the Branch Controller is the technological heart of the CITY MULTI R2/WR2. It works in unison with the outdoor unit to provide simultaneous cooling and heating, something no other two-pipe system can do. The BC is connected to the outdoor unit by two pipes and to each indoor unit by a series of two refrigerant pipes. The Branch Controller is required for all CITY MULTI R2-Series installations. It comes in 4, 6, 8, 12, and 16-branch options. The Branch Controller you select depends on the number of indoor units that will be operated from each outdoor unit and your total capacity requirements.
