General
The IAQ-sensor product eSENSE
(sensor for wall mounting) is designed to measure carbon dioxide
(CO2) 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 CO2 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.

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.
Electrical connections
The power supply has to be connected to and . is considered as system ground.
NOTE:
The same ground reference has to be used for the eSENSE unit and for the control system!

Self-diagnostics
The system contains a complete self-diagnostic procedure that is executed automatically when the
sensor is in operation. The yellow LED is lit if an error is found. Sensors with display show a wrench if
an error is found. The wrench is shown and the yellow LED is lit during the first seconds after power
up and if the measuring range exceeded. They are automatically turned off when the sensor returns to
normal operation. The output OUT2 indicates the same information by setting the output voltage to 1V
or 2 mA.
Maintenance
The eSENSE is basically maintenance free in normal environments thanks to the built-in self-
correcting ABC algorithm. Discuss your application with Senseair in order to get advice for a proper
calibration strategy.
