7. Product description
This powerful sensor will help you find our precisely when it is time to get some fresh air into residential or commercial spaces.
Installed simply in a wall-mounted housing, it measures the air quality (VOC gases), humidity and temperature. The measured
value is displayed using LEDs. VOC refers to gaseous and vapourous evaporations from people, installations, walls, etc. These
include hydrocarbons, alcohols, aldehydes, sulfur compounds and organic acids. The VOC sensor can be used for a range of
purposes, for example in school buildings, offices, hotel rooms, lecture theaters, meeting rooms, living rooms, commercial ar eas,
gyms, in building services and in climate recording.
Voltage output 7.1.
The VOC sensor provides an output scaling of 0 - 10 V, which represents the measuring range of 450 - 2000 ppm. In the version for
measuring relative humidity and temperature, a linear output scaling of 0 - 10 V is also supplied.

Power supply 7.2.
The device is supplied with voltage exclusively via the compression fitting 14 - 27 V DC.
Switching output 7.3.
A fan or window lifter can be controlled via the relay for ventilation.
8. Commissioning
Assembly 8.1.
1. Take the VOC sensor from the box and remove the packaging.
2. Drill holes to mount the sensor, observing the position of the cable outlet (Fig. 1).
3. Insert the 5 mm wall plugs included in delivery into the bore holes.
4. Screw in the screws until the screw heads are 5 mm from the wall.
5. Open the sensor.
6. Feed the connection wires through the wire outlet prior to mounting.
7. Place the housing on the screws so that the LEDs are arranged on the right, then turn the housing so that it is straight.
8. Using a small Phillips screwdriver, connect the power supply, along with any relay output and the voltage signal output(s). See pin
assignment, figure 2. The connection wires can be fed out from the housing directly beneath the compression fittings.
Avoid static charges and contact with electrical contacts. Electrostatic discharges can damage the device or sensor! Ensure that
no electrical voltage is applied on the wires. Connect the power supply (14 - 27 V DC) to the screw terminal AN1. See pin
assignment, figure 2.
9. Carefully insert the cover onto the enclosure base, so that the ventilation slots face upward and downward and the LEDs are
visible on the right-hand side.

Note: AN2, AN3 and AN4 not assigned on item no. 0565 0004
Description of the LED display 9.2.
This section briefly describes the range in which the VOC value lies when the LED display illuminates green, yellow or red:
The first LED illuminates green when the VOC value is below 800 ppm, meaning the air quality is good.
The second LED illuminates yellow when the VOC value is between 800 and 1200 ppm, meaning the air quality is moderate.
The third LED illuminates red when the VOC value is above 1200 ppm, meaning the air quality is poor.
The bottom LED illuminates red when the device is connected to the power supply.
Each time the device is rebooted, the three LEDs will flash for approximately 5 minutes. The VOC sensor is warmed up during this
time. The display will then switch to normal.
10. Error messages
Possible error message:
Green and red LEDs flash. A sensor was not recognized. Reboot the device.
Should the error not be resolved, please contact our customer service:
Tel. +49 771 8316-0 or info@bb-sensors.com.
