[. . . ] Take into account that data transfer range of remote sensor depends upon constructional material of partition walls and their number in the room. In spite of the fact that remote sensor is protected against negative weather it is required to install it thus to avoid exposure to direct sun radiation, rain or snow. [. . . ] Predictions accuracy: 70%; prediction of the considerable weather changes (for example, from sunny weather to rain) is more accurate then prediction of negligible weather changes (from partly cloudy to cloudiness). Weather station predicts possible weather, thus symbols could not agree with current weather. For more precise weather forecast it is required setting altitude above sea level. If your weather station is indicating "rain" or "storm warning" for a long time, and this indications do not comply with the real situation, try changing altitude above sea level gradually (in 20 meters/60 feet range) until the weather station indications get in accordance with real weather conditions. Increasing altitude above sea level Decreasing altitude above sea level Temperature and humidity indications Basic block is able receiving data from tree remote sensors, each of them has each own channel for temperature and humidity data transmission. Switching between data receiving channels Press button CHANNEL to switch between remote sensors' data receiving channels (Ch 1, Ch 2, Ch ), indoors (IN), switching between different channels' temperature data indication ( ) in cycle. Temperature and humidity trends Temperature and humidity trends are displayed by arrows (increasing, constant, decreasing) near the adequate data. Heat Index Temperature and humidity data are used for calculation of heat index. press button HEAT INDEX/DEW POINT once , symbols "HEAT INDEX" will appear on LCD. If heat index is too high, the next symbols are displayed on LCD: Caution Extreme Caution Danger Extreme Danger Undue fatigability while doing casual work. Strong tiredness, heat spasms are possible Heat stroke is possible Heat stroke danger Dew point Dew point is the temperature at given pressure the air is to ne cooled down to, in order to make water vapor condensation. press button HEAT INDEX/DEW POINT two times to display dew point , symbols "DEW POINT" will appear on LCD. [. . . ] Because of printing limitations display presented in these instructions may differ from the actual display in appearance. Manufacturer keeps right to change characteristics of the appliances without any prior announcements. [. . . ]
