[. . . ] It can be programmed to represent your local surroundings. Since the relative air pressure is also the one value given by various newspapers, TV and radio broadcasting stations in their daily weather forecasts for their respective locations, users can set the relative air pressure of the weather station to this value to represent readings your their area (see Basic Programming Modes below). 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 (saturation point), the excessive water vapor will condense and fall out in form of dew, fog or rain. 15° and a relative humidity of 50% the C dewpoint will be about 5° at 80% humidity about 1 2° At a C, C. relative humidity of 100% saturation is reached, i. e. the dewpoint is 15° At a dewpoint below freezing the fallout will C. 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 71 e. g. 8° and calm winds a person moving at a speed of 6 m/s C 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 direction as numerical (e. g. 225° and ) abbreviated characters (e. g. SW) as well as numerical wind speed display inside the compass circle. Operation keys The base station has 8 keys for easy operation. Please refer to the following table for use and function of each key: Further descriptions of the key functions with regard to their immediate range of application can be found in the Programming modes: SET - key - In normal mode to enter the manual basic programming mode - In basic programming mode to select the following setting modes: - LCD contrast setting - Manual time setting (hours/minutes) - 12/24 time format display - Calendar setting (year/month/date) - Time zone setting - ° F temperature setting C/° - Wind speed unit setting - Rainfall unit setting - Pressure unit setting - Relative air pressure setting - Weather picture threshold setting - Storm warning setting - Acoustic storm alarm setting - In setting modes confirmation of the selected values - In alarm modes alarm ON/OFF - In alarm mode to enter programming of alarm values (long pressing) - To exit MIN/MAX modes 72 PRESSUR E - key DISPLAY key WIND - key ALARM key - MIN/MAX key PLUS(+) ­ key - Toggle between Absolute and Relative air pressure displays - Toggle between the following current/ maximum/ minimum display modes: - Indoor temperature and humidity - Outdoor temperature and humidity - Outdoor wind chill - Outdoor dew point - Rainfall (24h, 1h, total) To toggle between the following settings: - Wind speed - Wind direction - Wind direction display in degrees - In normal mode to enter the alarm programming mode - In alarm programming mode to select the following setting modes: - Time alarm setting - Indoor temperature alarm (high & low) - Outdoor temperature alarm (high & low) - Indoor humidity alarm (high & low) - Outdoor humidity alarm (high & low) - Outdoor wind chill alarm (high & low) - Outdoor dew point alarm (high & low) - Rainfall alarm (24h, 1h) - Pressure alarm (high & low) - Wind speed alarm (high & low) - Wind direction alarm - In setting modes confirmation of the selected values - To exit MIN/MAX modes - To reset general alarm symbol - In normal display mode to toggle between display of MIN/MAX values - To toggle between MIN/MAX values in MIN/MAX mode - To exit any programming mode - In normal display mode to toggle between format of date display, seconds, time alarm and time zone - To increase the values in the setting 73 MINUS(-) ­ key modes - To exit MIN/MAX modes - In normal display mode to re-enter data learning mode (long pressing for 2 seconds) - In normal display mode to enable/disable the buzzer alarm (long pressing) - To decrease the values in the setting modes - In basic programming mode acoustic storm alarm ON/OFF - To turn the alarms off 24 hours when the alarm is sounding - In MIN/MAX modes to resets recorded values and recorded dates and times * Press any key to activate the LED Backlight 13. Basic Programming Modes Manual Setting modes The manual setting mode allows the user to change several basic settings, which is done by accessing one mode after the other simply by pressing the SET key. After the final mode, or if no key is pressed for 30 seconds, the manual setting returns to the normal display mode. [. . . ] Ensure that the rain sensor does not collect leaves or other dirt by checking the funnel for blockages every now 89 - - and then. Also clean the seesaw of the sensor with a damp cloth and check by lightly tapping with your finger that it can move freely from side to side. Do not clean the funnel with the bottom half of the rain sensor attached nor the bottom part itself under running water. This may bear the danger of water entering the unit's inner parts and cause damages. [. . . ]
