Can the unit be switched on for 24 hours in continuous operation or can it be switched on again each time the room is used?

Svar:

The CO2 traffic light is suitable for both applications. If it is only switched on when the room is in use, a longer service life can be assumed.
Nevertheless, the CO2 traffic light can also be disconnected from the power supply if necessary (e.g. in the evening). The warm-up phase (3 min, green LED flashes) starts when the system is put back into operation and the power supply is restored.
