Filter - Change filter settings The filters' primary purpose is to protect the ventilation aggregate's fans, heat exchangers and other components from the soiling in the air. It is therefore very important to change the filter when necessary, to ensure your system a long lifetime.

Air intake and extracted air filters are adjusted separately because if you choose an F7 Pollen filter, the lifetime of this filter is longer than for a standard G4 filter, and it therefore does not have to be replaced so often.

Filter settings are set in the Settings menu:

• Supply filter/Days from filter change Indicates how many days have passed since the last change of filter.

• Supply filter/Days to filter change Indicates the number of days that must elapse between switching filter. Recommendation: Standard G4 filter 90 days Pollen filter F7 180 days

• Supply filter/Supply SW filter reset After changing the filter, Click on ”OK” in ”Reset air intake filter”.

• Extract filter/Days from filter change Indicates how many days have passed since the last change of filter.

• Extract filter/Days to filter change Indicates the number of days that must elapse between switching filter. Recommendation: Standard G4 filter 90 days • Extract filter/Supply SW filter reset After changing the filter Click on ”OK” in ”Reset air intake filter”.

Filter - Filter monitoring As standard, filter monitoring is set as time-controlled (Timer), but can also be set for pressure-controlled monitoring, if required.

Filter monitoring is set in the Settings menu:

• Supply filter/Fresh air filter Set which filter monitoring is required • Hours: Counts the number of days (factory setting: 90 days) • Pressure: Pressure-controlled filter monitoring (accessory) • Free: • Digit: • None: No filter monitoring is required
