8.3 Limitation of Capacity Index for Heat Recovery
Single Branch Selector unit
Model BSQ36TVJ BSQ60TVJ BSQ96TVJ
Maximum number of connectable indoor units 4 8 8
Total capacity index of connectable indoor units unit ≤ 36 36 < unit ≤ 60 60 < unit ≤ 96
Multi Branch Selector unit
Model BS4Q54TVJ BS6Q54TVJ BS8Q54TVJ BS10Q54TVJ BS14Q54TVJ
Maximum number of connectable indoor units 20 30 40 41 41
Maximum number of connectable indoor units per
branch
5 5 5 5 5
Number of branches 4 6 8 10 12
Maximum capacity index of connectable indoor
units
144 or less 216 or less 290 or less 290 or less 290 or less
Maximum capacity index of connectable indoor
units per branch (*1)
54 or less 54 or less 54 or less 54 or less 54 or less
Note:
*1. When the total capacity of indoor units to be connected downstream is larger than 54 (Max. 96), use a junction pipe kit (KHRP26A250T, optional
parts) to join two connections downstream from the Branch Selector unit.


For indoor units used for cooling only (do not connect to Branch Selector unit when using for Heat Recovery),
total capacity index must be 50% or less than the capacity index of the outdoor units.
