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, 5, 6, 8, 10, 13, 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.
Sub-BC controller connections increased
Only two sub-BC controllers could be connected to a main BC controller in previous models. Up to 11 sub-BC controllers can now be connected to the new BC controller, allowing for more flexibility in system design. The line-branching method enables the creation of system designs that use less refrigerant.
Greater flexibility in refrigerant piping design
The piping length from the main BC controller to indoor units has been increased from 60m[196ft] to 90m[295ft], providing greater flexibility in piping design.
*Sub-BC controllers should be used when piping length is 60m[196ft.] or more.
Main BC controller with increased connection capacity
The connection capacity of the main BC controller has been increased compared to previous controllers, allowing system designs with fewer units. The KA type, which can be connected to units up to 44 HP, has been added to the product lineup to handle outdoor units with increased capacities.
Improved accessibility to lower surface and serviceability
Previously, the drain pan on conventional models was built into the bottom and could not be removed. The drain pan of the new model is installed on the lower surface like a cover, making it easily removable for service from below. Serviceability is therefore improved compared to conventional units, which need to be serviced from the side.
