C SERIES

Individual or 3-in-1 CO2, RH and Temperature

CWL

CDL

CDL/CWL carbon dioxide (CO2) sensors maximize energy savings, while
helping optimize ventilation. These sensors allow ventilation systems
to be controlled by the amount of CO
Series detect fluctuations in CO
provide an inlet of fresh air optimal for the space at a given time saving
energy and increasing tenant comfort.

AGENCY APPROVALS

**

RTD/Thermistors in wall packages are not compensated for internal heating of product.
EMC Conformance: Low voltage direc tive 2014/35/EU and EMC directive 2014/30/EU.
EMC Special Note: Connect this product to a DC distribution network or an AC DC power
adaptor with proper surge protec tion (EN 61000 -6-1 specification requirements).
* Measured at NTP.
**The CE mark indicates RoHS2 compliance. Please refer to the CE Declaration of
Conformity for additional details.
Note: Rough handling and transpor tation may cause a temporary reduction of CO
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.
