Filters alarm timing
5.1.b - Timing dirty filters alarm
It is possible to set the timing to 6, 9, 12 or 15 months (9 months factory setting). Fouling is linked to
the external environment (pollution, pollen,..) and the use of housing (dust, cooking fats..). It is
advisable to modify this parameter after the second alarm. Of course, after the installation, the extract
air is dusty and not representative of a normal conditions. During the second filter check, if you notice
that the filters are clean you can increase the time (12 or 15 ,months). However, if you notice that the
filters are very dirty should decrease the time (6 months).
Open the box and adjust the timing as shown. To do this, set the micro contacts 1 and 2 by the
number of months to suit your installation.
