not been powered recently, the LEDs may stay orange "breathing" for several minutes until the VOC
sensor stabilizes. The start-up cycle includes built in tests and preheating of the VOC sensor and visual
checks of LEDs
The cycle lasts about
5 minutes
in total. During this time no message is sent.
LEDs indicate faults as follows:
Led
Sensor failure after startup
Red Fixed followed by
blinking
End of Product Life (> 10 years)
Alternate Blue red
No power supply or reverse polarity.
Off
7. Indication of LEDs in normal operation
The LEDs show the overall synthesis of IAQ (physiological impacts on health cognitivity and quality of
sleep which depend on the combined effects (cocktail effect) of CO2, VOCs, particles, noise and light,
The building health is also synthesized and takes into account: risk of condensation, deposit of particles
on cold parts)
This synthesis is materialized by a continuous gradual rising and then descending gradation of the
breathing type.
