Operating note

Important information about all CO-2 traffic lights Please do not unplug your traffic lights overnight!

The traffic light uses the nightly rest periods to calibrate itself properly - just like during regular, daily shock ventilation in the rooms. Therefore, please leave the traffic light permanently switched on, i.e. on the mains, during operating and/or school hours.

The traffic light notes the lowest CO2 concentration of the last 7 days and always resets itself to its theoretical zero point in this rhythm. For this auto-calibration, the weekly average is much more meaningful than a daily average.

To save energy, the traffic light has a light sensor that darkens the LEDs after 10 minutes in absolute darkness, lowering the total power consumption.

That is why it is so important to supply the traffic light with power also at night. Only in case of school vacations / company vacations of more than 7 days, the traffic light can be taken off the grid.
