Measurement range CO2 0-2000 ppm (optional: 0-5000 ppm, 0-10000 ppm, 0-20000 ppm)
Accuracy 0-2000 ppm: ±50 ppm + 2% f. mv, 0-5000 ppm: ±50 ppm + 3% f. mv, else: ±100 ppm + 5% f. mv (at 20°C, 1013 mbar, auto-calibration ON)
Temperature dependency CO2: ±5 ppm / K
Pressure dependency CO2: 0,16% f. mv/hPa
Running-in time 10 min
Response time (t90) < 5 min
Long term stability ±1% FS/year
Sensor Nondispersive infrared sensor (NDIR)
Sensor protection mounted inside housing
Supply voltage 24 V AC/DC (±5%)
Current consumption Ø 100 mA
Analogue output 0-10 V 3-wire connection
Alarm output potential-free change-over contact max. 24 V (100 mA), threshold can be defined by 270° potentiometer
Switching Hysteresis Relay 2% FS (without Display), 0,5...5% FS adjustable (with Display)
Electrical connection screw terminals max. 1,5 mm²
Light switch program GIRA Standard 55, pure white satin (other on request)

Protection type IP30
Protection class III
Working range r.H. 0...98% r.H. in contaminant-free, non-condensing air
Working temperature 0...+50°C
Storage temperature -20...+50°C
Initial operation After switch-on of the device follows a self-test and the tempering, which takes ca. 10 minutes depending on the environmental conditions. At this time the analogue output drifts from the actual measurement value.
Installation into in-wall junction box, diameter 55 mm
Approvals CE, EAC, RoHS

The indoor air quality sensor CO2-U/A registers the CO2 concentration in the air in the environment in the range of 0-10000 ppm via a nondispersive infrared sensor (NDIR). For further processing a linear output signal 0-10 V or a changeover contact is available. The zero point balance depending on the actual ambient conditions can be performed on the device by manual calibration. The quality sensor performs an automatic self-calibration at regular interval, thus ensuring a long-term stable CO2 measurement.
