1.3 Calibration

The device uses automatic CO
eliminates the possible long term drift. The automatic calibration function can be used when the CO

the automatic calibration is effective in spaces that are not continuously occupied.
The automatic calibration function can be deactivated in continuously occupied spaces by using ML-SER
tool.
