CO2 concentr.: Send following change by
CO2 concentr.: Sensor correction (ppm)
CO2 concentr.: Send cyclically after
CO2 concentr.: Altitude above sea level (m)
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
control value CO
for the related stage is switched on. The
2
control value CO
is again switched off, if the CO
2
concentration returns to < switching point CO
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
control value CO
for the related stage is switched on. The
2
control value issues again the value of the next lower stage
when CO
concentration < switching point CO
2
Stage when overridden
Send cyclically after
