Frequently Asked Questions - AirCo2ntrol Life TFA

How does the CO₂ monitor detect carbon dioxide?

It uses NDIR (Non-Dispersive Infrared) technology, which measures the absorption of infrared light by CO₂ molecules in the air.

What do the LED colors mean?

Green indicates CO₂ below 800 ppm (good air quality). Yellow for 800–1200 ppm (moderate). Red above 1200 ppm (poor quality), and the buzzer will sound if enabled.

How long does the monitor take to warm up?

The first warm-up after powering on is 2 minutes. During this time, the LCD shows four bars and the mute button is disabled.

Can I turn off the alarm sound?

Yes, press the MUTE button to toggle the buzzer on/off. The setting is remembered until changed.

What power source does the device use?

It can be powered via USB (5 VDC) or the included AC/DC adapter (5 VDC, 1000 mA). Only use the specified adapter.

How accurate is the CO₂ measurement?

Repeatability is ±20 ppm at 400 ppm. Accuracy may be affected by electromagnetic fields above 3 V/m.

How should I clean the device?

Disconnect power before cleaning. Use a damp cloth only; do not use benzene, thinner, or aerosols.

What should I do if the display shows an error code like Err3 or Err5?

Err3 indicates temperature outside the operating range (0–50 °C). The error clears when temperature normalizes. Err5/Err6 indicate an EEPROM problem; try reconnecting the adapter. If persistent, contact service.

Can the monitor be used in high humidity environments?

The operating humidity range is 0–95% RH non-condensing. Avoid condensation as it may damage the device.

Where should I place the CO₂ monitor for best results?

Place it in a well-ventilated area at about breathing height, away from direct heat sources, windows, or vents. Ensure air can diffuse freely into the sensor.

5020-0105 CO2 Monitor (CO2+Temp.+RH) Operating Instructions

Product Overview

Thank you for selecting 5020-0105 desktop CO 2 monitor, 5020-0105 CO 2 monitor is smart, compact and easy-to-use. In addition to measuring the CO 2 concentration, 5020-0105 can also measure the ambient temperature and the relative humidity (CO 2 +Temp. +RH). This product is developed to detect the presence of CO ₂ in ambient air and help people to take care of Indoor Air Quality. 5020-0105 can be widely used in the office building, school, exhibition hall, shopping mall, meeting room, fitness center, restaurant and other public places where personal comfort, healthy is important.

Features:

□, V Three different LED display shows the current Indoor Air Quality
□, V Press MUTE button for alarm on/off.
□,V Built in the LCD Backlight for easy reading in the dark.

Warnings:

☐, V Please take off the AC power adapter and store it well when this CO2 monitor left idle for long.
□, V This CO2 monitor is for home use, not suitable for certifying the test results.
☐, V If use this CO2 monitor for testing, 5020-0105 does not guarantee the test results.

EMC/RFI

Readings may be affected if the unit is operated within radio frequency electromagnetic field strength of approximately 3 volts per meter, but the performance of the instrument will not be permanently affected.

Note: Under the electromagnetic field of 3V/m, the reading will not meet the specification.

Warm-Up Time: 2 MIN.

1. 2 min. warm-up time when first time power.
2. The LCD shows 4 bars with 1sec blank cycle during warm-up
3. The MUTE button is disabled during warm-up
4. The device shows the CO2 reading after warm-up

Using the MUTE function:

Press MUTE button to select buzzer on/off. If the "MUTE" function is off, while CO2 concentration exceeds the alarm level (>1200 ppm), there will be a buzzer.

Note: The device setting with alarm is buzzer on when power on first time, user can set the alarm on/off under MUTE function.
