Important information about all CO-2 traffic lights
Please do not unplug your traffic light 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, during operating and/or school hours. The traffic light memorizes 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, thus lowering the total power requirement.
That is why it is so important to supply the traffic lights with power even at night.
Only in case of school vacations / company vacations of more than 7 days, the traffic light can be taken off the network.
