LED Display
The "LED traffic light" switches off approx. 800ppm from green to yellow and from approx. 1200ppm to red. The
switching thresholds of the LED display are permanently programmed.
You can permanently activate the "night function" of the traffic light function by long pressing of the calibration
button on the device connection side. In the delivery state, the night function for the traffic light LED is not active,
which means that the traffic light LED illuminates independently of the ambient brightness.
If the night function is activated, the LED display is switched off by an internal light sensor during darkness in
order to be able to sleep undisturbed during the night, for example. The light sensor is only intended for
brightness control of the LEDs and cannot be read out externally.
All sensor functions remain in operation even when the LEDs are switched off. When mounting, make sure that
the sensor is not darkened, otherwise the LED display may be permanently off.

Commissioning and warm-up
A calibration of the temperature and humidity sensor is not necessary. The air quality sensor is pre-
calibrated.
After applying the supply voltage, the integrated sensor controller checks the warm-up time after which the
air quality sensor starts. The three possible stages of the warm-up phases are indicated by the three LEDs
on the front.
It is normal for the 1-Wire air quality sensor to require a "warm-up time" after connecting the supply voltage.
During commissioning, the integrated sensor controller checks which warm-up stage the sensor starts with.
The three possible stages of the warm-up phases are indicated by the three LEDs on the front.

green
<800ppm
Lights up for CO2
Good air conditions
- If the power supply was only briefly interrupted, the
sensor starts normal operation directly without
warm-up time.
- The LED illuminates in good air conditions up to
approx. 800 ppm CO2 in the air.
yellow
CO2 >
800ppm
- Initial commissioning:
Flashes during the start phase
for approx. 2 hours.
- Operation:
Sufficient air conditions
- The LED flashes as a sign of the start phase.
- The 1-Wire interface constantly outputs 0 ppm of the
air quality value.
- After the warm-up time, the sensor switches to
normal operation.
red
CO2 >
1200ppm
- Commissioning:
Flashes during the start phase
for approx. 15 hours.
- Operation:
LED flashes, poor air
conditions.
- The LED flashes as a sign of the start phase.
- The 1-Wire interface constantly outputs 0 ppm of the
air quality value.
- After the warm-up time, the sensor switches to
normal operation.
