Filter monitoring with pressure measuring sensor

Alternative monitoring of filter usage times using pressure measuring sensor. This involves determining a differential pressure and saving a pressure loss characteristics curve for every volumetric flow (HPV, RV, NV, IV) with clean filters.

With the Permissible Delta p parameter, the maximum permissible increase in pressure is specified in %.

Before activating filter monitoring, be sure to insert new air filters in the ventilation unit.

If the Filter monitoring parameter is set to yes, the ventilation unit is set to the current pressure loss – the unit runs through the entire volumetric flow range from RV to IV for 10 minutes.

This initialisation sequence takes place whenever a filter change is acknowledged. For additional information about filter monitoring, see accessories instructions.
