Central ventilation unit – KWL 200/300 W/W ET
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. 41).
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.
4. Enter the determined differential pressures from the supply and intake air measurement in the unit characteristic
curve for supply air (see Fig. 32, Fig. 34, Fig. 36 and Fig. 38) according to the fan outputs saved in the ventilation
profile (cf. Fig. 41, Fig. 42).
5. Enter the determined differential pressures from the extract and exhaust air measurement in the unit characteristic curve
for extract air (see Fig. 33, Fig. 35, Fig. 37 and Fig. 39) according to the fan outputs saved in the ventilation profile (cf.
Fig. 41, Fig. 42).
