CO Module Troubleshooting
In most configurations, the AQSync has two CO sensors. For improved accuracy, the
AQSync gives an average of their measurements. The output of the two sensors can
be monitored through the CO Parameters screen. If the readings are systematically
changing, with one sensor drifting higher or lower than the other, replacement of the
sensor is indicated. Ideally, the two sensor readings should be within ~20% of each
other.
