Determine system characteristic curves for supply and extract air:
1. Install pressure measuring connectors in the unit supply, extract, exhaust and intake air ducts (see Fig. 32).
ⓘ Ensure approx. 20 cm straight settling section up to the measuring connectors !

2. Enter the following values for the fan powers in the respective ventilation profile via the easyControls software or the
control element KWL-BE Touch: Away: 30 % / At home: 50 % / Boost: 80 % (cf. Fig. 33).
3. Select the individual ventilation profiles (At home, Away, Boost) one after the other and measure the static differential
pressure between extract and exhaust air and supply and intake air respectively.
