Installation and Operating Instructions
Central ventilation unit – KWL 360 W/W ET
Determine fan powers:
1. Enter the flow rates from the design calculation for the three ventilation profiles "At home", "Away" and "Boost" in the
unit characteristic curve for supply and extract air (cf. Fig. 32).
ⓘ We recommend entering the following values in the ventilation profiles:
• Reduced ventilation ≙ Ventilation profile "Away"
• Nominal ventilation ≙ Ventilation profile "At home"
• Intensive ventilation ≙ Ventilation profile "Boost"
Total air flow rates by fan-assisted ventilation according to DIN 1946-6:2019-12

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 (cf. Fig. 32). Enter these in the corresponding ventilation profile via
the easyControls software or the control element KWL-BE Touch (cf. Fig. 33).
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. 34).
