Frequently Asked Questions - AirCo2ntrol Up 31.5011.10 TFA

What does the AirCo2ntrol Up measure?

It measures CO2 concentration, temperature, and humidity in indoor air.

How does the alarm work?

The device triggers an audible and visual alarm when CO2 levels exceed a preset threshold (e.g., 1000 ppm). You can adjust the threshold via settings.

Can I use it with batteries only?

Yes, it can be powered by 3 AAA batteries (not included). However, for continuous use, the USB-C connection is recommended.

How do I calibrate the sensor?

The device features automatic baseline calibration (ABC). Place it in fresh outdoor air (400 ppm) for a few minutes to recalibrate manually.

What is the recommended placement?

Place at 1.5 m (5 ft) above floor level, away from windows, vents, and direct sunlight. Avoid areas with high humidity or rapid temperature changes.

How accurate is the CO2 reading?

Accuracy is ±50 ppm or ±5% of reading (whichever is greater) at room temperature.

Does it have a data logging function?

No, this model does not have internal memory for storing historical data. It provides real-time readings only.

How do I clean the device?

Wipe the exterior with a soft, dry cloth. Do not use water or cleaning agents. Keep the sensor openings free from dust.

What does the backlight do?

The LCD backlight automatically illuminates when a button is pressed or when an alarm occurs. It can be set to always on via USB power.

What is the expected lifespan of the sensor?

The NDIR sensor typically lasts more than 5 years under normal use. Calibration may drift over time, requiring periodic recalibration.

5. Getting started

Important note:

When using the device for the first time, please make sure to connect the power supply uninterruptedly for 24 hours. The device will perform an automatic calibration within 24 hours.

- Plug the supplied USB-C cable into the designated port on the device and connect the unit to the mains using the power adapter.

6. Operation

• Press the POWER/LIGHT sensor button for 3 seconds to switch on the device.
• The device will issue two beeps and all segments will be displayed briefly.
• The display shows the current temperature and humidity.
• The CO ₂ sensor goes into warm-up mode and starts a 150-second count-down. Afterwards the normal display appears. The device is ready for use.
• Press the UP/°C/°F button in normal mode to change between °C (Celsius) or °F (Fahrenheit) as temperature units.
• Briefly press the POWER/LIGHT sensor button to adjust the brightness in 4 steps (high, medium, low, off).
• Press the POWER/LIGHT sensor button for 3 seconds to deactivate the device.

10. Calibration of the CO₂ sensor

10.1 Automatic calibration of the CO₂ sensor

- The sensor is automatically calibrated every 24 hours to the lowest CO ₂ reading obtained during that period to keep the deviation low during prolonged use. To perform the calibration, the power supply must be connected continuously for 24 hours.

AIR CO2NTROL UP Single Beam - CO2 Monitor

• For proper functioning, it is therefore necessary to ensure maximum ventilation at least once a day. Otherwise, the device is using a faulty basis for automatic calibration and an incorrect display may occur. In this case, a restart under fresh air conditions or a manual calibration as described below is recommended.
• Note: The product is not suitable for a location where ideal ventilation is not possible (in permanently closed rooms).

10.2 Manual calibration of the CO₂ sensor

• For the whole calibration process, place the device outdoors. Choose a shady and dry place. Wait 15 minutes, the device must adapt to the environment.
• Use a pin to press the RESET button at the bottom. Wait until the normal display appears (see point 6. "Operation").
• Then press and hold the DOWN/CALIBRATE button for 2 seconds to enter the manual calibration mode. The CAL symbol flashes.
• Wait approx. 20 minutes, until the normal display with a CO ₂ concentration of 400 ppm (fresh air) appears. The calibration is completed and the device returns to normal state. Now you can use the device again as usual.
• During the manual calibration operation, press the DOWN/CALIBRATE button to exit the calibration mode.

11. Care and maintenance

• Clean the device with a soft damp cloth. Do not use solvents or scouring agents.
• Turn off the device if you do not use it. Press the POWER/LIGHT sensor button for 3 seconds.
• Store the device in a dry place.
