General
The IAQ-sensor product 06(16( ®(sensor for wall mounting) is designed to measure
carbon dioxide (CO2) in rooms. Option 'displays the measured CO2value 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) give
linear signal voltages corresponding to the measuring range 0-2000 ppm carbon dioxide.
The 2-10V output also indicates the status by setting the output voltage to 1V 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.

Electrical connections
The power supply has to be connected to G+ and G0. G0 is considered as system ground. The
same ground reference has to be used for the 06(16(®unit and for the DDC/signal
receiver.
PLEASE NOTE!
The same ground reference has to be used for the 06(16(®unit
and for the control system!

Self diagnostics
The system contains complete self diagnostic procedures that is executed automatically when
the sensor is in operation. Sensors with display show a wrench if an error is found. The
wrench is shown during the first seconds after power up and if the measuring range 2000 ppm
is exceeded. The output OUT2 indicates the same information by setting the output voltage to
1V.
PLEASE NOTE!
The sensor accuracy is defined at continuous operation (at least 3 weeks after
installation).
This product is in accordance with the
EMC Directive 89/336/EEC and the
