Humidity set value
Configuration of the humidity/temperature sensors. The configuration applies to all con-
nected sensors.
Humidity control On/Off, Stepped, Continuous

ttEntIOn
active as information display sensors.
"Off"
"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 dis-
played 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
thres- hold 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 de-
ac- tivated for the set time (0-24h), the step size is 1h.
(Factory setting: 1h)

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
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)

The lowest set value should therefore be at least 500 ppm .
