[. . . ] to 0 hrs. 4. 1 Weather forecasts This Irox device uses a high quality pressure sensor to measure barometric pressure and the respective changes. This information is then, using a by meteorologists specially developed algorithm, used to calculate a weather forecast for the coming 12-24 hrs. Eight different forecasts are possible: Static stacking bars, only the 0 hrs bar blinks Sunny Slightly cloudy Cloudy Rain Heavy rain Snow Heavy snowfall Thunderstorms /Stormy COMMENT: These calculated weather forecasts have a reliability of approx. SUNNY means clear weather day and night. 4. 2 Air pressure indicator The indication of the air pressure depends on the setting of the sea level. This value is based on the factory calibration of the pressure sensor. If you have programmed the height above sea level of your location you will see the barometric pressure measured at your location, calculated from the local pressure measured and the set height above sea level. With this value you can meteorologically position your location with other available information (e. g. With the height adjustment setting you can also adjust any slight deviations to a precision measuring instrument and so to say calibrate the pressure sensor. Static line diagram, only the segment 0 hrs blinks 46 47 4. 4 Temperature / Moisture The display unit measures the temperature and relative humidity and receives additional measurements from the remote sensors included in the delivery. The comfort zone is calculated from the thermo/hygro measurements of the display unit. When the temperature measured by the remote sensor drops below 3°C, the frost warning icon will appear on the display. 4. 5 Time function The time signal DCF 77 is transmitted by the atomic clock in Mainflingen near Frankfurt/Main. Please observe following points: If the time icon - There are fewer disturbances in the atmosphere during the night which increases the likeliness of reception. One reception per day is completely sufficient to ensure the preciseness of the clock by +/- 1 second - Make sure that the device is at least 2 meters (8 feet) away from possible sources of disturbance such as TV, computer, monitor, microwave etc. SEARCH FOR REMOTE SENSOR You can start the search for the remote sensor manually by pressing and holding the SYNC start to blink. The wave icon indicates the receiving status of the remote sensor signal: Icon Status Searching for the remote sensor signal Sensor signal successfully received No signal received for over an hour button for 3 seconds. cellar rooms, modern office buildings etc. ) the receipt of the signal may be more difficult due to the shielding. Sometimes it also helps to simply turn the device by 90°, thereby improving the alignment of the receiving antenna. Caution: During the setting procedure as described below you will exit the setting mode if more than 1 minute passes between pressing the buttons. As described in chapter 3 the time transmitted by the time signal transmitter DCF77 is automatically received when the batteries are icon will blink, if reception is good with waves if activated. During normal operation an automatic time reception will be activated daily at 0:00, 3:00, 6:00 and 12:00. As soon as the device has received a signal the time will be correctly adjusted and the 5. AM/PM - Setting the hours - Setting the minutes We recommend this operating mode for locations where the time signal can not be received. TROUBLESHOOTING If you notice a malfunction of your device, always first check the battery please. [. . . ] Stone, asphalt, or tar surfaces can become extremely warm and thus falsify the measurement. · Heat sources such as a fireplace or heaters of any type must be avoided. · The display unit must be positioned within the transmitting radius of the sensor and away from the direct influence of heating or cooling apparatus. A distance of at least 1 meter must also be maintained between sensor and display unit and other remote equipment. [. . . ]
