diffuser in red. During this period it is necessary to keep the equipment powered
so as not to interrupt the self-calibration process.
Manual calibration AIRSENS CO2
For those situations where automatic calibration is an impediment, a forced
manual calibration can be performed. To do this, press the button (see Fig.1) for
more than 10 seconds until the light guide flashes intermittently in green. During
the next 10 minutes of flashing it is essential that there is no occupation in the
area, windows remain open and/or the ventilation system at maximum perfor-
mance in order to obtain the best CO
the light guide will stop flashing and the AIRSENS CO2 will consider that the CO
level in that moment is 450ppm.
Reset
Manual way to start a reset process is disconnecting power supply, wait at least
30 seconds and power again the electronic control. It is also possible to do re-
motely via Modbus communication using General reset (register number 3).
