General

The IAQ-sensor product CF3-W-EU (sensor for wall mounting) is designed to

measure carbon dioxide (CO

) 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

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

Figure 1. Closed housing seen from

above. The housing is opened by

pressing a screw driver on the locking

hook. The locking hook is then

released.
