INOVENT: CO2 sensor

A microprocessor - controlled room sensor with automatic calibration is used to record the CO2 content in the air range from 0 ... 2000 ppm. The measured value is converted to a standard 0 - 10 V signal. Elegant housing made of plastic with a snap - on lid, 4 mounting holes, can be installed vertically or horizontally. CO2 sensor in vandal - resistant design for schools, barracks and public buildings, for example. The PPM content in the air is measured using an optical NDIR sensor (non - dispersive infrared technology).

1. Install the CO2 sensor in the required position by fixing with 4 screws (not included)
2. It is necessary to install a 4 - core cable from the CO2 sensor to the unit (not included)
3. Use 2 - wire 24 VAC and the other 2 wires for a 0 - 10 V signal
4. Ground GND is common, so inside the sensor - UB GND will have 2 wires
5. Remove the 230 V power cable from the box and connect it to the transformer with the connections identified by the PRI 230 V
6. Two wires for 24 VAC are connected to the transformer at connections aware of SEC 24 V, 24 VAC/DC and 3 GND inside the CO2 sensor at point 1
7. The other 2 wires for the 0 - 10 V signal are connected to the connection of the air handling unit that is CO2 - aware via the DIM connector (included in the kit) and inside the CO2 sensor in point 2.
