General
The IAQ-sensor product CF3-W-EU (sensor for wall mounting) is designed to
measure carbon dioxide (CO
2
) in rooms. Option - TR is prepared for temperature
measurements by the resistive temperature probe mounted by the user. The
temperature probe is potential free (floating). Option - Disp displays the measured
CO
2
value in ppm (parts-per-million) on the LCD.
The units are designed for connecting to Direct Digital Control (DDC) with 0-10V or
2-10V signal inputs. The two parallel signal outputs OUT1 (0-10V) and OUT2 (2-10V
or 4-20 mA) give linear signal voltages or currents corresponding to the measuring
range.
The output OUT2 also indicates the status by setting the output voltage to 1V or the
output current to 2 mA when the sensor self-diagnostics detects any error.
To open the wall mounted housing

pressing a screw driver on the locking
hook. The locking hook is then
released.
