Placing the air quality monitor

After shipping and removing the protective packaging, the product must be placed in a well-ventilated area for a two hours prior to set up and use to clear the sensors ready for use (2). To ensure proper operation of the unit, place the monitor on a piece of furniture and in a location that allows the sensors (2) to remain unobstructed. Keep away from all direct sources of carbon dioxide, liquid products, heat, flammable products and magnetic fields.

Connect the indoor air quality monitor

Plug the power cable into slot (11) and connect the USB plug into a powered USB port (230V adapter,
computer…). The icon appears above the time to confirm correct connection. The screen lights up.
A 5 minutes countdown is shown on the display while the device warms up and prepares for operation. After the countdown, the monitor displays the VOC (3), CO2 equivalent (4), temperature and humidity (7) measurements of the room.
Important : Do not make any adjustments during countdown.
Important : When the monitor is on USB power, the measurements are displayed continuously and updated automatically every 5 seconds. The back light is on. It is necessary to keep monitor on USB power to ensure proper functioning.
Important : Do not place battery in the compartment. This power option is not available and does not enable the functioning of air quality monitor

Setting the Time:

Press and hold down button (9) until the hour digit flashes. Press buttons ‘+’ and ‘-‘ (10) to set the time. Press button (9) again and the minute digits will flash. Set the minutes with the buttons ‘+’ and ‘-‘ (10). Press button (9) to finalize the setting. The time display is set.
Important: If no button is pressed for 10 seconds while setting the time, the screen returns to the standby display.
In standby mode (normal display), briefly press the up button ‘+’ of (10) to select 12H or 24H format. In 12H mode, the ‘AM’ or ‘PM’ icon appears to the left of the time.

Setting the temperature units

In standby mode (normal display), briefly press the down button ‘-’ on (10) to select the temperature units Celsius (°C) or Fahrenheit (°F). The display changes automatically (7).

Air quality display:

The Quaelis 20 monitor is used to measure the accumulation of various Volatile Organic Compounds (VOCs) and to indicate the equivalent CO2 content of the room.

➢ Carbon dioxide is a colourless, odourless gas that comes from a variety of sources (greenhouse gases, transport, fuel, heating…).
Carbon dioxide (CO2), a molecule that is naturally present in the atmosphere, is produced by the human body during respiration. Its concentration inside buildings is proportional to the rate of occupation and the renewal rate of the air. The current regulatory standards limits vary between 1000 and 1500 ppm.

Risks vary with exposure to CO2

• Mild exposure: slight headache, nausea, fatigue…
• Moderate exposure: throbbing headache, drowsiness, confusion…
• Extreme exposure: loss of consciousness…

Thus the comfort indices for CO2 are defined according to the following measures:

• Up to 700 ppm. The air is good quality.
• 701 to 1199 ppm. It is recommended to ventilate the room.
• From 1200 ppm. It is necessary to ventilate and leave the room in order to renew the air.
  Values in a room above 2000 ppm can cause nuisance to the occupants: it is recommended to leave the room, ventilate and improve the air quality.
  Important : The monitor has a display range up to 9999 ppm. We recommend not to exceed 2000 ppm in a room

➢ Volatile Organic Compounds are pollutants from hydrocarbons, solvents, exhaust gases, furniture, ceilings, paints, glues…
The comfort indices (5) for VOCs are defined according to the following measures:

Important: When the VOC Comfort Index is poor, ventilate the room to renew the air. Do not stay in the room when the quality index is bad.

Conditions of use and safety

Use the indoor air quality monitor for its intended purpose.Do not modify the product and do not repair it yourself. Only use the connection accessories supplied with the product. The manufacturer is not liable for damages relating to the product if it is improperly used or maintained. Keep away from children.

Maintenance / safety:

Do not use cleaning products containing caustic or abrasive agents and pollutants. Keep away from all direct sources of carbon dioxide, liquid products, heat, flammable products and magnetic fields

Solving any problems encountered

The monitor does not turn on.

|

Check that the USB port is powered (computer on, plug on…). Check that the cable is correctly inserted in the intended slot (11).

The battery is not charging.

|

The monitor is not equipped with a built-in rechargeable battery. The monitor must be powered continuously to ensure functioning.

Do not use batteries or rechargeable batteries. This power option is not available and does not enable the functioning of air quality monitor.

The screen displays ‘LL’. The screen displays ‘HH’.| This means that the temperature is below the minimum display range (-9°C). This means that the temperature is above the maximum display range (+50°C).

The time is not correct.

|

When the display shows ‘AM’ or ‘PM’, it means that the time is shown in 12-hour format. Change the format (24 or 12 hour clock) in the ‘Time setting’ parameter.

The monitor beeps.| When a button is pressed, the monitor beeps.

Measurements do not change or do not appear to be correct.

|

If the measurements do not change, turn the monitor off and place it in a ventilated area or outdoors for 30 minutes to clear the sensors. Then turn on again. Observe the instructions for installing the monitor as described in the manual. Sensors can wear out over time.

If measures remain incorrect, proceed to factory reset. Long press “ – ” of button (10). Screen displays “REST”. Press button (9) to confirm. Countdown appears.
