Operating instructions
Comfort controller KWL-BEC
Format adjustment: Options: DD.MM.YYYY; MM.DD.YYYY; YYYY.MM.DD
Automatic Action: When checkbox "On" is activated, the summer-/wintertime changeover
summer/wintertime will take place automatically. When checkbox "Off" is activated, the time will not
be automatically adjusted.
Configuration of The control behaviour of the KWL ventilation unit can be adjusted via unit
ventilation unit configuration. There are two different configurations:
1 = DIBT: The heat exchanger frost protection is activated at < - 0 °C outside
air temperature and ensured by the (optional) preheater or air volume reduction. In
case of a supply air temperature of < +5 °C, the fans are switched off.
2 = PHI: The heat exchanger frost protection is activated at < -3 °C outside air
temperature (PHI specification) and ensured by the preheater stipulated by the
Passivhaus-Institute. In case of a supply air temperature of < +5 °C, the fans
are switched off.
Heat exchanger Options: "Plastic", "Aluminium" or "Enthalpy"
type:
Fan stages 1-4: Extract air: Control voltage of extract/outgoing air fan
Supply air: Control voltage of supply/outside air fan
The fan stages can be adjusted via the "System settings" menu (Password:
0103)
Options:
Minimum fan
stage: Stage 0 = Switch-off function can be activated
Stage 1 = Switch-off function cannot be activated (min. FS 1)

(Factory setting: On)
HUMIDITY CONTROL Options: The status of the humidity control can be configured to
(only displays if a "Off", "Stepped" or "Continuous".
humidity sensor is "Off"
connected!) "Stepped"
"Continuous"
Depending on the humidity level, the fans are continuously regulated (fan stages
0-1-2-3-4) between voltage stage 0 and voltage stage 4. The percentage control
is displayed on the web server page or on the comfort controller KWL-BEC (Fac
tory setting: Continuous).
Required settings
Only humidity: Only the humidity value is transferred to the humidity control, the room
temperature is not used for the auxiliary heating control.
Only temperature: Only the room temperature is transferred to the auxiliary heating control, the
humidity values are not used for the humidity control.
Combined: Both the humidity value and the room temperature are transferred to the
respective controls.
(Factory setting: Combined)
