A check is made to see whether the air quality sensor is connected when existing
the commissioning menu. If the sensor is not connected at this point, the "Indoor
air quality control" function is set inactive.
If the sensor is connected at this time but missing later, message "Sensor fault X.."
appears and the "Indoor air quality control" function is set inactive.
