4. CO
2
setpoint
The device continuously measures the level of CO
2
in the air and compares the measured value to a configured
setpoint value. The device controls the ventilation accordingly to keep the measured CO2 level below the
requested level. When in Comfort mode, the requested level is equal to the configured value. In Eco mode,
the requested level is 250 ppm above the configured value.
NOTE:
The device stores the configured fan speed values in the control device, and requests them from there.
The device stores the CO
2
setpoint itself, and does not communicate this with any other device.
