C SERIES
Deluxe Duct and Wall
CO2 Sensors
VERIS INDUSTRIES
Individual or 3-in-1 CO2,
RH, and Temperature
DESCRIPTION
CDL/CWL carbon dioxide sensors maximize energy savings, while ensuring optimal
ventilation. These sensors allow ventilation systems to be controlled by the amount
of CO2 present in a space. The CWL/CDL Series detect uctuations in CO2 levels and
signal ventilation systems to provide an inlet of fresh air optimal for the space at a
given time saving energy and ensuring tenant comfort.
APPLICATIONS
● Controlling ventilation in response to occupancy
● Facilitating compliance with ASHRAE 62.1 standard for air quality
● Oce buildings, conference rooms, schools, retail stores, etc.

EMC Conformance: Low voltage directive 2006/95/EC and EMC directive 2004/108/EC.
EMC Special Note: Connect this product to a DC distribution network or an AC/DC power adaptor with proper surge protection (EN 61000-6-1:2007 specication requirements).
Note: Rough handling and transportation may cause a temporary reduction of CO2 sensor accuracy. With time, the ABC function will tune the readings back to the correct accuracy range. The default tuning speed is limited to
30 ppm per week.
