Fig. 29:
Entering threshold values / switch-off delay
The ventilation is controlled via threshold values. An action is triggered when one of these
threshold values is exceeded or drops below the set value. E.g. a window is opened when the
entered CO
threshold value is exceeded.

Information
CO
(carbon dioxide) is naturally present in the air. Conclusions can be drawn
2
about the quality of the air on the basis of its concentration within closed rooms.
The CO
threshold value can be set on the device between 800 ppm and
■
2
1500 ppm in steps of 10 ppm.
The display is illuminated in red as long as the CO
■
exceeded.
After initial commissioning it can a certain amount of time until the CO
■
is measured with its final accuracy.
The relative humidity describes the amount of moisture in the air in dependence
of the air temperature.
The optimum value of the relative humidity depends on the local conditions.
■
The RH threshold value can be set on the device between 40% and 80% in
■
steps of 1%.
The display is illuminated in red as long as the RH threshold value is
■
exceeded.
