Product Overview

CD series duct mount CO

sensors measure the levels of CO

, RH (if equipped), and temperature (if equipped)

of air inside a duct. The CO

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 Guide Air Quality CD Series TM Installation Observe precautions for handling static sensitive devices to avoid damage to the circuitry that is not covered under the factory warranty. 1. Choose a location to mount the sensor. The centerline of the housing must be parallel to the direction of air flow in the duct. 2. Use the mounting diagram to drill the four holes in the duct for securing the sensor. 6.7" (170 mm) 2.2" (55 mm) 1" (25 mm) typ 1" diameter 3.1" (78 mm) CL 0.4" x .0.

Installation Guide Air Quality CD Series ABC Calibration Algorithm TM 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 significant amount of drift is detected, the ABC applies an automatic correction factor.
