If the blockage of 2 aspiration apertures out of a total of 5 aspiration aper-
tures is recognised, then with the help of the diagnostics tool flow monitoring
can be set to ±15 %.
NOTICE
For a project planning according to EN 54-20 or ISO 7240-20, the air flow
monitoring has to be adjusted to ≤20 % in either case.
