Weather Data (LCD Section 2)
Indoor temperature and humidity are displayed simultaneously in this
section. Use the DISPLAY key to toggle through the displays for other
weather information:
- Outdoor temperature/humidity
- Outdoor wind chill
- Outdoor dew point
- Rainfall 24h
- Rainfall 1h
- Rainfall total.
Notes to Dewpoint and Windchill:
Air can at a certain temperature only carry a certain amount of water
(water vapor), which also increases and decreases with temperature.
If the air temperature decreases below the so called dewpoint (satura-
tion point), the excessive water vapor will condense and fall out in
form of dew, fog or rain. At a temperature of e.g. 15° C and a relative
humidity of 50% the dewpoint will be about 5° C, at 80% humidity
about 12° C. At a relative humidity of 100% saturation is reached, i.e.
the dewpoint is 15° C. At a dewpoint below freezing the fallout will
become frost or snow.
Windchill has been introduced for battle planning during World War II.
It represents not the real measured but the one temperature a person
feels in open area under the influence of wind and cold. Windchill is
laid out in tables for various temperatures and wind speeds. At an
outdoor temperature of e.g. 8° C and calm winds a person moving at a
speed of 6 m/s will already feel a windchill temperature of 0° C.
Wind Data (LCD Section 3)
The current wind direction will be displayed on the LCD compass on
the wind section. Press the WIND key to toggle between wind direc-
tion as numerical (e.g. 225° ) and abbreviated characters (e.g. SW) as
well as numerical wind speed display inside the compass circle.
