Humidity set value
Configuration of the humidity/temperature sensors. The configuration applies to all connected
sensors.
Humidity control On/Off, Stepped, Continuous
ATTENTION
: When the humidity control is switched off, the temperature sensors remain active as
information display sensors.
„ 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.
(Factory setting: Continuous)
Set value
Lower limit value of humidity control.
The larger the difference between the actual value and the set value, the higher the fan control.
Setting range from 20 % RH to 80 % RH, the step size is 5 % RH.
(Factory setting: 45 %)
Switching step
The switching step is only relevant for the control mode „Stepped“ . It indicates the threshold in rel.
humidity, which was set as the limit value for the change of relative humidity Steps of 5 % can be
set between 5-20 %.
If the set value is fallen below or exceeded by the value defined in the switching step, the next
operating stage of the ventilation unit will be activated.
(Factory setting: 10 % RH)
Stop time
If there is no change in speed after two hours of ventilation, the humidity control is deactivated for
the set time (0-24h), the step size is 1h.
(Factory setting: 1h)
CO

set value
Configuration of the CO

sensor. The configuration applies to all connected sensors.
CO

control
„ Off ” CO

„ Stepped ” CO

control active with stepped control logic
„ Continuous ” CO

control active with continuous control logic
Depending on the CO
2
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
(Factory setting: Continuous)
Set value
Lower limit value of CO
2
control.
The larger the difference between the actual value and the set value, the higher the fan control.
Setting range from 300 ppm to 2000 ppm, the step size is 50 ppm.
(Factory setting: 1000 ppm)
ATTENTION: CO
2
concentration in the outside air is normally between 400-450 ppm!
The lowest set value should therefore be at least 500 ppm.
