22 Set weather status and air pressure above
N.N
NOTICE! For a correct display of the weather forecast, the current weather status and the air
pressure above N.N. must be set correctly immediately after commissioning. The first weather
forecast will be displayed approximately 6 hours after the set-up.
NOTICE! These settings should also be made again when chnaging the location of the unit.
1. After switching on the unit, press the WEATHER/ABS/REL button for 3 seconds. The weather
symbol on the display flashes.
2. Select the graphic symbol corresponding with the current weather status by pressing the UP or
DOWN button.
3. Press WEATHER/ABS/REL button to enter the next setting. The air pressure value flashes.
4. Set the current value for the air pressure above N.N. by pressing the UP or DOWN key.
5. NOTICE! Information on the current value for the air pressure above N.N. can be found on
the Internet at https://www.dwd.de/DE/leistungen/beobachtung/beobachtung.html
6. Finally, press the WEATHER/ABS/REL button to save the settings and return to the normal display

24 Barometric / Atmospheric Pressure
Atmospheric Pressure is the pressure at any location on earth, caused by the weight of the column of
air above it. One atmospheric pressure refers to the average pressure and gradually decreases as alti-
tude increases. Meteorologists use barometers to measure atmospheric pressure. Since variation in
atmospheric pressure is greatly affected by weather, it is possible to forecast the weather by measur-
ing the changes in pressure.
1. Press the BARO button to enter the setting mode.
2. Press the BARO button again, to change the unit between inHg / mmHg / hPa.
3. Press the BARO button for 3 seconds to change between absolute and relative atmospheric pres-
sure.
