Unit ppm

Co2 alarm frame and CO2 “led” indicator are updated/evaluated each time a CO2 sensor measurement (sampling) is performed (according to S321 value, sampling period).

Note: CO2 LED indicator is not associated to an alarm frame.

These registers allow to update QAI led repetition period (i.e.: speeding up the led indication or decrease rate to optimize power consumption).
