After activating the volumetric flow measure
-
ment, the fans are run for a maximum of
3 hours in nominal ventilation.
This allows the supply and exhaust air volu-
metric flows in the building to be calibrated
without the air volumes being changed by
sensor values. The function switches off
automatically after 3 hours.
If
deactivate
is selected or the installer level is
exited, this function switches off immediately.

The setpoint volumetric flow setting applies to
both fans. With humidity protection ventilation,
the fans run in interval mode
13 min. RV – 17 min. Off – 13 min RV etc.
We recommend setting the volumetric flow for
NV first.
The RV and IV volumetric flows are set auto-
matically by the control on the basis of the
NV reference value 1/3 less than (RV) and 1/3
greater than (IV).
Example
310/410
320/470
NV 150 m³/h
RV 100 m³/h, IL 200 m³/h.
Example

The IV and RV volumetric flows can also be
set manually. Condition:

Supply and exhaust air volumes must be
balanced over the entire application area. Nor-
mally the fans automatically ensure a balance
and no adjustment has to be undertaken.
