Central ventilation unit – KWL 500 W/W ET
2. The approximate fan powers to be set (in %) can be read from the ventilation profiles at the points of intersection of
the flow rates and the system characteristic curve. Enter these in the corresponding ventilation profile via the easy-
Controls software or the control element KWL-BE Touch (cf. Fig. 31 and Fig. 32).
Example: Ventilation profile "Away" = 31 %
Ventilation profile "At home" = 55 %
Ventilation profile "Boost" = 78 %
3. Select the ventilation profile "At home" under the menu item "Homepage".
4. Select the menu item "Configuration".
5. Enter the fan powers for supply and extract air according to the determined values for nominal ventilation under "Fan
setting" (cf. Fig. 33).
6.4.3 Perform flow rate measurement for adjusting the system (fine adjustment)
• Measure the flow rates at all valves in the supply and extract air ducts.
• Add up the flow rates for the supply and extract air ducts.
• In case of deviations from the desired flow rates, adjust these accordingly by increasing or reducing.
• Adjust valves according to the design.
• Measure the flow rates at all valves in the supply and extract air ducts again to check the correct adjustment and
the total flow rate
