Frequently Asked Questions - AirSens CO2 Soler & Palau

Where to install the AirSens CO2 sensor?

Install the sensor protected from water sprays (IP30), on a flat surface, at a height between 1.5 and 1.8 m. Avoid direct sunlight, proximity to an occupant, direct drafts from windows, doors or ventilation systems.

How to connect the AirSens CO2 to the WiFi network?

Download the CONNECTAIR app, register, then select the '+' icon to add a device. Follow the connection steps. You can also use a computer by connecting to the WiFi network 'AIRSENS WIFI_XXXX' (password 0000+4characters) and opening http://10.10.10.1.

What to do if the WiFi connection fails?

Check that your network is on 2.4 GHz. If you previously connected the device to another network, reset the WiFi antenna by pressing the button (bottom left corner) for 5 seconds, then repeat the procedure.

What are the different operating modes?

The modes are configured via micro-switches SW1-4: MF1 (relay + Connectair), MF2 (output 0-10V + Connectair), MF3 (output 2-10V + Connectair), MF4 (Connectair controller). See the combination table in the manual.

How to manually calibrate the CO2 sensor?

Press the button (Fig.1) for more than 10 seconds until the light bar flashes green. For 10 minutes, the room must be unoccupied with windows open and/or ventilation at maximum. After 10 min, the flashing stops and the sensor considers 450 ppm.

What do the LEDs on the main board mean?

Red LED D17: device powered on; flashing red D16: communication failure with WiFi antenna; intermittent yellow D18 (every 60 s): communication established with antenna.

How to interpret the colors of the LED diffuser?

In MF1 mode: green = value below setpoint, red = above. In MF2-4 modes: green ≤800ppm/60%RH/21-25°C; orange between 800-1200ppm/60-80%RH/18-21°C and 25-35°C; red >1200ppm/>80%RH/<18°C or >35°C. A special mode (SW4=ON) changes thresholds: green ≤950ppm, orange 950-1350ppm, red >1350ppm.

What is the measurement accuracy?

CO2: ±50 ppm; VOC: 100 ppm; relative humidity: ±2%; temperature: ±0.4 °C.

How to reset the device?

Turn off the power, wait at least 30 seconds, then turn it back on. This resets the electronic control unit.

What maintenance is required?

Regular inspection is required to prevent dirt accumulation. Always disconnect the device before cleaning. Frequency depends on usage conditions.

SECURITY

Installation must be carried out by a qualified professional. Make sure that the installation complies with mechanical and electrical national regulations. Once in service, the appliance must comply with corresponding Directives.

Do not use this device in explosive or corrosive atmospheres.

This appliance is considered to be suitable for use in countries having a warm damp equitable climate as specified in IEC 60721-2-1. It may also be used in other countries.

This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children must not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

INSTALLATION

This device must be installed in a dry environment (IP30), over a flat surface through fixing points (see Fig.3) and will require a type X installation. Height installation recommended between 1,5 and 1,8m . At the same time, it is important to choose an installation location free of conditions that could influence the measurement such as direct sun light, too close occupant proximity, air flow coming from windows or doors or ventilation systems.

The front cover is opened a tool pressing both pressure closures located at both edges of the cover (see Fig.4). For safety reasons, cables must be retained using the support provided (see Fig.5).

In case of an installation where cabling is outdoors, it must be installed inside a cable ducting system with IP4X protection degree classified as "cable ducting with access cover that can only be opened with a tool" according to UNE-EN 50.085-1: Cable trunking systems and cabling ducting systems for electrical installations-Part 1: General requirements.

START UP

WIFI network connection (via CONNECTAIR® App)

To connect to a WIFI network within the range of the equipment and direct to the platform CONNECTAIR®, follow steps below:

1. Sign up.
2. Follow the steps once you select the "+" icon on the main screen:

WIFI network connection (via computer)

To connect to a WIFI network within the coverage of the equipment and to direct to the CONNECTAIR® platform, follow steps below:

1. Turn on the AIRSENS WIFI device. The red D17 LED from main PCB board will light.

2. Connect your device (smartphone, tablet, computer) with the WIFI network genera ted by the AIRSENS WIFI device. Depending on device used, will be necessary to deactivate 4G/5G mobile network.

3. Search the available WIFI network in the menu of your device and select:

a. Network: AIRSENS WIFI + 4 characters (Ex.: AIRSENS WIFI 47b1)

b. Password: 0000 + 4 characters shown in the name of the network (Ex.: 000047b1)

1. Once connected (1), open your device's browser and enter the IP address (http://10.10.10.1) and follow the instructions on the screen. Through this interface, the AIRSENS WIFI device will connect to the fixed WIFI network (must be 2,4GHz) within the coverage of the equipment. Use your WIFI network password.

2. Access to www.connectairapp.com and register by following the instructions on the screen [2].

3. When you have registered, you can assign the unit by entering the serial number [SERIAL NUMBER] with ten digits, which you will find on the back side of the equipment cover, scanning the QR code or on the electronic board.

4. The first time that an AIRSENS WIFI device is linked with the CONNECTAIR platform, it is necessary to use the command "Obtain password" for its generation and validation. Make sure the mobile device and AIRSENS are connected to the same WIFI network.

(1) In case of an error in the connection, the WIFI network of the device will remain visible for an hour. Try again.

(2) In case of having disabled 4G/5G mobile network, activate to be able to enter to website address.

IMPORTANT: In case of many AIRSENS WIFI devices within the same range, carry out a connection procedure to the WIFI network in a staggered and individual way per device.

In case to link the AIRSENS WIFI device to a new WIFI network, when it has already been linked to another one, previously reset the WIFI antenna by pressing the button located in the lower left corner for 5 seconds (see Fig.1). Then follow the steps described above.

LED diffuser

The device displays a real-time concentration level. In operation mode 1, the illumination is two-color while in modes 2, 3 and 4 this is three-color.

Relay + Connectair (reading) - [SW1-4=OFF]

Green: Value below set point.

Red: Value above set point.

Other modes

Green: ≤ 800ppm / ≤ 60%HR / 21-25°C

Orange: 800 - 1200ppm / 60 - 80%HR / 18-21 °C and 25-35°C

Red: > 1200ppm / > 80%HR / <18°C and >35°C

Special limits are provided in the LED diffuser for cases where AIRSENS is installed in an area with permanently high concentration. This special mode is activated by SW4=ON.

New colour limits

Green: ≤slant 950ppm

Orange: 950 - 1350ppm

Red: > 1350ppm

CALIBRATION / RESET

Automatic calibration

AIRSENS intelligent IAQ sensor incorporates a self-calibration algorithm that allows adaptation to the environment. This adaptation could be prolonged for two weeks until the reading is fine-tuned, and there may be periods of time with LED diffuser in red. During this period it is necessary to keep the equipment powered so as not to interrupt the self-calibration process.

Manual calibration of CO2 Sensor

For those situations where the automatic calibration was a problem, we can force a manual calibrate pushing the button (see Fig.1) during more than 10 seconds until the light guide blinks on color green.

During the following 10 minutes we have to avoid occupying the same room and we must open the windows and/or the ventilation system in maximum performance in order to obtain a level of C02 similar to the outdoor area. After 10 minutes, the light guide will blink off and the equipment is going to consider that the concentration is 450ppm .

Reset

Manual way to start a reset process is disconnecting power supply, wait at least 30 seconds and power again the electronic control.
