Room air quality control

To display this section, enable the option "Activate room air quality control" in Device
Default switching point stage 1 (ppm)
Default switching point stage 2 (ppm)
Default switching point stage 3 (ppm)
Hysteresis
If the CO concentration exceeds a switching point CO
2
value CO for the related stage is switched on. The control value CO
2
is again switched off, if the CO
point CO – hysteresis.
2
Control value stage 0 (%)
Control value stage 1 (%) (>stage 0)
Control value stage 2 (%) (>stage 1)
Control value stage 3 (%) (>stage 2)
If the CO concentration exceeds a switching point CO
2
value CO for the related stage is switched on. The control value
2
issues again the value of the next lower stage when CO
concentration < switching point CO
Stage when overridden
Send cyclically after
