The control behaviour of the KWL ventilation unit can be adjusted via 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.
A comfort temperature of 16.5 °C is defined in the KWL unit configuration (2 = PHI).
This default temperature is determined by the PHI. If the supply air falls below 16.5 °C,
the pre-heater or auxiliary heater (if available) is used to heat the supply air. The
comfort temperature can be individually adjusted by overwriting.
The function of the humidity control is solely to reduce the humidity by increasing the
air exchange.
The status of the humidity control can be configured to
"Off", "Stepped" or "Continuous".
"Off" Humidity control deactivated
"Stepped" Humidity control active with stepped control logic
"Continuous" Humidity control active with continuous control logic
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
Only the humidity value is transferred to the humidity control, the room temperature is
not used for the auxiliary heating control.
Only the room temperature is transferred to the auxiliary heating control, the humidity
values are not used for the humidity control.
Both the humidity value and the room temperature are used for the controls.
Indicates the desired max. humidity value in the setting range between 20-80 % RH;
step size 5 % RH
Indicates the % rel. humidity which is set as the limit value for the change of rel.
humidity. The adjustment is possible in 5 % steps from 5-20 %. If the set value is
exceeded, the next higher stage will be activated until the value falls below the set
value.
If it is not possible to reach the set value within 2 hours, the humidity control will be
deactivated for the stop time.
Setting range between 0-24 hours; step size 1 hour.
The status of the CO control can be configured to
2
"Off", "Stepped" or "Continuous".
"Off" CO
control deactivated

"Stepped" CO
control active with stepped control logic

"Continuous" CO
control active with continuous control logic

Depending on the CO 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.
Indicates the desired max. CO
Setting range between 300-2000 ppm; step size 50 ppm.
The threshold indicates when the next fan stage will be activated, e.g. set value 1000
ppm, switching step 150 ppm. If the measured value is between 850-1000 ppm, stage
1 will be activated. If the CO
stage will be activated (stage 2).
Setting range between 50-400 ppm; step size 50 ppm.
The status of the VOC control can be configured to
"Off", "Stepped" or "Continuous".
"Off" VOC control deactivated
"Stepped" VOC control active with stepped control logic
"Continuous" VOC control active with continuous control logic
Depending on the VOC 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
