General

The IAQ-sensor product CF3-D (for mounting in ventilation ducts) is designed to

measure carbon dioxide (CO

). Option - TR is prepared for temperature

measurements by the resistive temperature probe mounted by the user. 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 or

2-10V signal inputs. The two parallel signal outputs Out(1) (0-10V) and Out(2) (2-10V

or 4-20 mA) give linear signal voltages or currents corresponding to the measuring

range.

The output OUT(2) 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.
