Set on ALL main PCBs (A1P, A2P and A3P) of the BS unit.
(b)
Assign a unique cluster number to each cluster in the system. All
BS units in the same cluster MUST have the same cluster
number.
(c)
Set ONLY on the LEFTMOST main PCB (A1P) of the BS unit.
Note: For more information, see "16.1Making field settings"[436].
BS unit test run
Before BS unit operation, it is required to perform a test run that
simulates a refrigerant leak. See "17.2 BS unit test run" [4 40] for
more details.
Multiple BS units in series – one extraction fan
In this configuration, multiple BS units are connected in series to a
single extraction fan. The air flows through every BS unit to the
extraction fan. In case of a refrigerant leak in any BS unit, the
dampers of all BS units will open and allow air evacuation to the
extraction fan.

d Extraction fan
It is sufficient to connect the extraction fan circuit to only one BS unit
of the cluster (see "15.5To connect the external outputs"[435]). It
is not allowed to have BS units in the same series cluster that belong
to different outdoor unit systems.

NOT allowed
The option kit EKBSDCK is required each time a duct is connected
to the air inlet (damper side) of the BS unit.
An online tool (VRV Xpress) is available to find the required pressure
capacity for selecting the correct fan size. Only use this online tool
for the calculation.
