After having changed a ventilation level, select the changed ventilation level in the 'manual
ventilation mode'. The updates will now be performed. You can now switch back to 'automatic
ventilation mode'.
Level 4 (design extraction airflow) has to be activated in the manual ventilation mode if you
want to measure the nominal airflow.

This menu is used to adjust the ventilator capacity which can be
necessary when calibrating the system.
The ventilation system needs to be manually calibrated by
means of adjustable design extraction grills or adjustable
extraction valves.
Calibrating the ventilation system
When calibrating the system, it has to be manually set at ventilation
level 4 which is the design level for adjusting the extraction airflow.
Level 4 has a default value of 70%. This percentage can be adjusted
upwards or downwards if the extraction airflow proves insufficient
or too much in certain rooms.
After level 4 is determined, you can now define 3 more levels.
• The percentages can be set at a range between 100% and 20%
(20% = min. ventilation level)
• There is always a minimal difference of 5% between the different
ventilation levels
o %L1 + 5% ≤ %L2
o %L2 + 5% ≤ %L3
o %L3 + 5% ≤ %L4
