General

The IAQ (indoor air quality) sensor product CF3-W-EU-Disp-FLI (sensor for wall

mounting) is designed to measure carbon dioxide (CO

) in rooms. The acoustic alarm

sounds when the carbon dioxide concentration is above 1400 ppm CO

. A push

button silences the alarm for 30 minutes. Green, yellow and red LEDs give a rough

estimate of the CO

concentration Option -Disp displays the measured CO

value in

ppm (parts-per-million) on the LCD.

The units are designed for connecting to Direct Digital Control (DDC) with 0-10V

signal inputs. The signal output OUT1 (0-10V) gives linear signal voltage

corresponding to the measuring range.
