Overview of BSQ Box Range & Features
Daikin heat recovery systems provide the option of single or multiple
port BSQ (branch selector) boxes
Note: When multiple units are grouped together on a single port, although a single
heat/cool zone is created, units still operate independent of each other irrespective
of whether they are grouped together on one room controller or individual controllers.
