What is the device for?
EClerk-Eco-A measures temperature, relative humidity and carbon dioxide (CO2) concentration in the air with high precision. Signals on exceeding the set values.
EClerk-Eco-R is equipped with a two-position controller that allows you to adjust the values of temperature, relative humidity and CO2 content in the air with operational units (heating element, fan, humidifier, waste heat exchanger, etc.)
EClerk-Eco can also be used for express control of microclimate parameters in any room to assess the operation of the ventilation system of a house.

Why is it important to control air quality?
As for the impact on human health, air quality and life expectancy is significantly ahead of other factors, such as genes, water, proper nutrition, etc. More than 7000 liters of air pass through the lungs per day (we eat only 3 … 4 times a day).
There is a misconception that when we have nothing to breathe, it means lack of oxygen. No – it’s an excess of CO2. Changes in the oxygen content in the air do not affect human health so significantly. It’s a change in CO2 concentration by tens of percent that is really significant!
In a school classroom with plastic windows, CO2 concentration can reach 1500 ppm in just half an hour after the lesson has started. Such a concentration (at a normal rate of up to 600 ppm) leads to headaches, a drop in concentration, negative changes in blood and the respiratory system.
A person cannot feel the quality of the air. He or she can say that he likes some kind of food. That the food is low-fat and contains a lot of greens, which means the needed vitamins. But he or she cannot say for sure what we are breathing now. That is why the instrumental control of air quality is very important: relative humidity, temperature and carbon dioxide content.
Why is EClerk-Eco
better than others?
THE BEST CHOICE
The optimal device for monitoring air quality at home, in the kindergarten and at school.
HIGH PRECISION
High measurement precision for all parameters, which is characteristic of expensive professional devices only.
ALARM OR REGULATION
Thresholds exceeding alarm or automatic regulation for each parameter.*
LARGE SCREEN
Convenient large backlit screen for simultaneous display of all the measured parameters.
EXPRESS CONTROL
The meters are powered from an external network. Additional batteries allow using the device as a portable means of express control of parameters.
* * The EClerk-Eco-R meter is optimal for automatic control of supply ventilation, air humidifier, heating element, etc. in the “smart home”.
How to use
an air quality meter?
- Where is the best place to install the EClerk-Eco meter?
- Can the meter work only by self-contained batteries?
- How to regulate temperature, humidity and carbon dioxide content?
- How does the meter’s sound alarm work?
- What data is displayed on the meter screen?
- How to install and configure the EClerk-Eco-A air quality alarm?
- How to install and adjust the EClerk-Eco-R air quality regulator?
For accurate control of temperature, air humidity and carbon dioxide concentration, the device should be at least 2 m away from the heating radiator. The sun rays should not reach the meter.
EClerk-Eco-A (R) meters use mainly the external power supply. Battery power is back-up and allows you to use the device when the external power is turned off, or as a portable meter for express control of air quality in various rooms.
The EClerk-Eco-R meter-regulator is designed to regulate the microclimate parameters. Regulation is carried out by means of operation units connected to the device. For example, a heating element (for temperature control), a humidifier (to maintain the required humidity level), a fan / waste heat exchanger (for timely ventilation of the room to maintain an optimal CO2 level). For each microclimate parameter you can set the minimum and maximum allowable value on the device screen.
The EClerk-Eco-A meter-signaling device is equipped with a sound alarm function. When the sound alarm is triggered, a short signal is issued every 4 seconds. If the measured parameter gets to its norm, the alarm is turned off. You can also turn off the alarm by pressing any button on the meter.
1. Installation and connection
- Remove the bracket off the device, pressing the bracket down with your fingers and pulling it down.
- Choose a place in the room for installing the meter and fix the bracket to the wall using the two supplied anchors and screws.
3. Open the battery compartment cover and install the batteries observing the correct polarity.
4. Install the meter in the wall-mounted bracket.
5. Connect the external power supply to the device by plugging the power adapter into the socket and the cable into the microUSB connector of the device.
2. Setup
- Entering the Setup mode is carried out by short pressing the M button.
- The upper line displays the previously set upper temperature threshold.
- Use the “Up” – “Down” arrow buttons to set the desired value.
- Press the M button, the set parameter enters the memory of the meter, and the meter goes on to set the next parameter.
- Set the upper and lower alarm limits for all measured parameters.
- Press the M button to enter the next current time setting mode. Set the time using the Up – Down arrow buttons, then press M.
- The meter will switch to the mode of enabling / disabling the sound alarm: on – enabled, off – disabled. Select a mode and press M.
1. Installation and connection
- Remove the bracket off the device pressing the bracket down with your fingers and pulling it down.
- Choose a location in the room for installing the meter and fix the bracket to the wall using the two supplied anchors and screws.
3. Make a channel for hidden wiring or install a cable duct between the installation site of the appliance and the switching unit.
4. Route the cable in the cable duct.
5. Connect the cable to the clip connector in the battery compartment of the meter, but at first you should press out the perforated window in the bracket of the meter. When using the meter with a load control unit connected, it is NOT RECOMMENDED to install the battery compartment cover and batteries in the meter, which are recommended for using the meter in stand-alone mode for express control of air quality in various rooms. It is recommended to use a colored cable for an easier connection.
6. Install the meter in the wall-mounted bracket.
7. Connect the cable to the clips of the load control unit.
8. Connect the AC power cord to the load control unit after disconnecting the supply voltage.
9. Connect the power supply wires for external loads, such as outlets for connecting external control devices, to the load control unit.
10. Place the load control unit into the socket box and secure with screws.
11. Turn on the AC power.
2. Setup
- Entering the setup mode is carried out by long pressing the M button.
- The upper line displays the previously set upper temperature threshold.
- Use the “Up” – “Down” arrow buttons to set the desired value.
- Press the M button, the set parameter enters the memory of the meter, and the meter goes on to set the next parameter.
- Set the upper and lower thresholds for all measured parameters.
- Press the M button to enter the next current time setting mode. Set the time using the Up – Down arrow buttons, then press M.
- The meter will switch to the mode of enabling / disabling the sound alarm: on – enabled, off – disabled. Select a mode and press M.

EClerk-Eco alarm helps to cope with asthma
Nearly 10% of babies have a tendency to develop asthma. But you can significantly reduce its symptoms, including coughing attacks in the evening and at night. Install the device on the wall not far from the crib and set the required alarm limits. If the temperature, humidity or CO2 go beyond the limits, the device will notify you with a sound signal. Using the controller will automatically adjust these parameters.
Air quality control will improve academic performance
Students often become inattentive in the classroom, lose concentration and poorly learn new material. The main reason is the high content of carbon dioxide in the air. The majority of schools are not equipped with a supply and exhaust ventilation system for each class. And plastic windows do not allow air to pass through. As a result, within 30 minutes from the beginning of the lesson, the level of CO2 in the classroom begins to exceed 1500 ppm at a normal value of 400 … 600 ppm.
EClerk-Eco meters – monitor air quality
Our life expectancy directly depends on the quality of the air that our children breathe at home, in the kindergarten and at school. The longest life expectancy is found in the island states surrounded by water and blown around by clean moist wind. The EClerk-Eco signaling device or regulator will help improve the quality of the air that we and our children breathe by continuously monitoring the 3 most important parameters – temperature, humidity and CO2.
