LED indication description
White LED lights:
Less than 40 % RH or less than 18 °C.
(according to the quantity selected for indication)
 low concentrations of RH. Too dry air feels
cooler as compared to equally hot but more
humid air – risk of drying of the mucous
membranes - respiratory problems
 low temperature and its higher fluctuation is
not economically profitable
Green LED lights:
More than or equal to 40 % RH or 18 °C, less than
or equal to 60 % RH or 22 °C.
(according to the quantity selected for indication)
 optimal relative humidity for humans
 optimal balance of air quality and energy
efficiency of ventilation and air conditioning
Yellow LED lights:
More than 60 % RH or more than 22 °C.
(according to the quantity selected for indication)
 too high humidity, the risk of mold growth
and associated health complications
 higher temperature T - high temperature can
cause fatigue, restlessness, headache and
feeling hot
Sensor start after power on
All three LEDs flash simultaneously until the first
readings are available, but no longer than 10 seconds.
Sensor failure indication
All three LEDs are shining permanently.
CAUTION:
Warm-up: operational after 1 minute since power on.
The declared accuracy is reached after 4 days of
continuous power supply.
It is necessary to avoid severe mechanical shock of the
sensor.
