To Replace Humidity Sensor:
1. Power down unit
2. Remove CDL from duct to
access probe tip.
3. Open tip of duct probe

ABC CALIBRATION ALGORITHM
ABC (Automatic Baseline Calibration) is a patented self-calibration feature that
automatically adjusts the CO
2
sensor to compensate for drift. When ABC is enabled,
the sensor records the lowest reading within every 24-hour interval and compares
these values over a running 7-day or 28-day period. If a statistically significant
amount of drift is detected, the ABC applies an automatic correction factor. This
enables the sensor to operate within specifications for the 5-year calibration interval.
ON POSITION. Recommended Setting. Use the ON setting for applications where the
building is unoccupied within a 24-hour timeframe.
LOW POSITION. Use the LOW setting for buildings occupied 24 hours a day.
OFF POSITION. Not Recommended.
NOTE: After changing the ABC settings, power cycle the unit for changes to take effect.
To set the ABC mode for CDL models, refer to the Configuration section on page 3.
To set the ABC mode for CDE models, position the ABC jumper as shown:
