Fresh air means more oxygen - in other words, more well-being and better performance. Because too little oxygen makes us weak and tired - and ultimately more susceptible to illness. But no one wants to freeze - so it's important to find the right balance. The small 1×1 of energy-saving ventilation is quite easy with our CO2 traffic light "school" - because it switches to yellow exactly when it is time to ventilate - not much too early and not much too late. And the traffic light also switches back to green in good time when there is enough oxygen in the classroom again. So no one has to freeze anymore, just because the room was aired out too long and extensively. This, of course, saves a lot of heating and climate costs that would otherwise have gone out the window. The CO2 traffic light itself has a very low energy consumption - and also switches off the LED lights at night, which makes it even more economical.
Ventilate & save energy at the same time
The CO2 traffic light "school" is available not only in green, but also in white or gray - or painted in the RAL color on request. The enclosed wall bracket is mounted on a wall as far away as possible from the nearest window / door at a height of 1.8 - 2 meters and the power supply unit with its 2.3 meter long supply cable is plugged into a socket. After three minutes warm-up phase the CO2 traffic light "school" is ready for operation. In addition, you can order an anti-theft device, a ball protection grid or a stand. As soon as the CO2 traffic light "school" lights up yellow (from 1000 ppm) open a window and ventilate until the traffic light turns green again. Often people ventilate too short, too long or too often, which causes unnecessary heating or air conditioning costs. At night, the LED lights dim automatically, which is why the CO2 traffic light "school" is particularly energy-saving.
