INSTALLATION GUIDE

OPERATION

CD series duct mount CO2 sensors measure the levels of CO2, RH (if equipped), and temperature (if equipped) of air inside a duct. The CO2 sensor operates within accuracy specications for an interval of 5 years and can be eld calibrated. The temperature element is warranted to meet accuracy specications for a period of 5 years. RH equipped models feature a replaceable HS Series humidity element that is warranted to meet accuracy specications for a period of 1 year. To maintain accuracy, all vents must remain clear and free of dust, debris, etc.

INSTALLATION

Observe handling precautions for static sensitive devices to avoid damage to the circuitry which

1. Choose a location to mount the sensor. The centerline of the housing must be parallel to the direction of air ow in the duct.

2. Use the mounting diagram to drill the four holes in the duct for securing the sensor.

NOTE: This product is factory calibrated. The typical CO2 sensor calibration interval is 5 years , depending on specic site installation factors. A s of the date of this document, compliance with ANSI/ASHRAE 62-2001 requires minimum on-site accuracy verication intervals of 6 months or per the building operation and maintenance manual. Verif y accuracy using a comparison to a known reference or the CO2 gas calibration kit available from Veris Industries as AA01.

WARNING: CO2 sensor calibration requires gas calibration kit. Performing calibration with out gas kit or at an incorrect gas ow rate will cause erroneous readings.

ABC Settings (CWE only)

CD SERIES

INSTALLATION GUIDE

ABC CALIBRATION ALGORITHM

ABC (Automatic Baseline Calibration) is a patented self-calibration feature that automatically adjusts the CO2 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 signicant amount of drift is detected, the ABC applies an automatic correction factor. This enables the sensor to operate within specications 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 setti ngs, power cycle the unit for changes to take eect.

To set the ABC mode for CDL models, refer to the Conguration section on page 3.

To set the ABC mode for CDE models, position the ABC jumper as shown:
