General
The IAQ-sensor product eSENSE (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 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 OUT1 (0─10V) and OUT2 (2─10V or 4─20mA)
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
2mA when the sensor self-diagnostics detects any error.
