6.8 Dew point
•
To view the current dew point temperature, press the
button (C) until DEW appears in the outdoor data
display.
•
LL.L is displayed if the dew point is below 0°C, and
HH.H is displayed if the dew point is above 60°C.
•
The display automatically switches back to the current
temperature and humidity display.
•
The relationship between temperature and relative
humidity is expressed through the dew point: If air is
continuously cooled and absolute humidity remains the
same, relative humidity increases up to 100%. If air
cools further, the excess water vapour is precipitated
as droplets.
6.9 Heat index
•
The heat index is a value specified in the unit of
temperature. This value describes how hot it feels based
on the measured outdoor temperature and, above all,
the relative outdoor humidity.
•
If the temperature is below 26.7 degrees, the heat index
shows the currently measured values.
•
If the temperature is above 26.7°C, the weather station
in HEAT mode displays the apparent temperature; this is
calculated by taking into account the outdoor humidity
and outdoor temperature.
6.10 Frost alarm
•
The snowflake symbol
(22) flashes if the outdoor
temperature is b1 and -1°C.
•
The snowflake symbol
(22) remains displayed if the
outdoor temperature is below -1.1°C.
