1. General information and functioning The WS 300US Radio Weather Station is a high-quality universal weather measuring system that processes a wide range of weather data and additional information and can display both current values and forecasts. All relevant data are displayed simultaneously on the LCD display, while additional data can be called up at the press of a button as required. The figure of the "Wiz Kid" is a special feature.
Display of the change / trend in air pressure: - Graphic display of the changes in the last 24 h - Display of the air pressure trend in 5 steps: rising steeply, rising, no change, dropping, dropping steeply Symbolic indication of the weather forecast: rainy, cloudy, fine, sunny Indication of the time and date - Integrated quartz clock Indication of sunrise and sunset - Based on the location data to be entered individually, can be calculated in the range of the degrees of latitude -60 to +60˚ N Moon phase di

2. Preparation for operation Start up all outdoor sensors first, then the base station. 2.1. The outdoor sensors The following outdoor sensors are available for the weather station: - KS 300US combi-sensor: This is a permanently addressed combination sensor consisting of rain sensor, instant rain detection sensor, wind speed sensor, outdoor temperature/humidity sensor and integrated transmitter unit. Operation is by means of three Mignon batteries.
The sensor will now be in synchronisation mode for about 5 minutes, during which one data packet will be sent every 4 seconds. - Close the housing again by pushing it up and turning it clockwise until it engages. - Erect the now fully assembled sensor within the possible transmission radius (up to 100 m in the open, but make allowances for the attenuating effects of walls etc.
Setting up/Wall mounting Depending on requirements, the weather station can be hung on a vertical surface (wall) by means of the attachment eye or set up on a horizontal surface using the fold-out desk stand. - The desk stand is erected as illustrated in the following pictures. It is important that the short claws of the desk stand are first inserted into the brackets on the rear of the unit.
In configuration mode the keys have the following functions: IN → not used Leave configuration mode SENSOR → EXIT MIN/MAX → + Increase value RAIN →– Decrease value OUT → NEXT To the next setting This key assignment is also shown on the rear of the weather station. Please note! If you press and hold down the "+" or "-" keys during the individual setting operations, the figures will run through more quickly.
+ – Day NEXT + Press "NEXT" to go to the minutes setting. – Minute NEXT + Set the day using the "+" and "-" keys. Set the minutes using the "+" and "-" keys. Press "NEXT" to go to the hours setting. – NEXT Hour Display "dSt" Set the hours using the "+" and "-" keys. Press "NEXT" to go to the setting of the daylight-saving-time status. This is indicated by "dSt" in the display.
- can copy its position indication to obtain an exact location. Exact coordinates can also be obtained from the Internet. There are numerous sites which deal with navigation. Remember that strictly speaking the information for sunrise and sunset applies only by the sea or for land that is completely flat. Mountains, high forests etc. can reduce the actual daytime considerably. Even in an ideal location the figures may deviate by a few minutes since an approximation formula is used for the calculation.
All the settings required for the weather station to operate normally have now been made. The expanded settings are not needed for normal operation. EXIT Quit configuration Press the "EXIT" key to leave configuration mode and return to normal mode. Expanded settings Press the "NEXT" key in order to make expanded settings and to calibrate the rain sensor.
Assigning the indicator path The movement of the air pressure, the inside or the outside temperature can be illustrated in the display field of the graphic indicator path. If the indicator path is assigned to one of the two temperature displays, the additional symbol " " appears in the relevant display field. Abbreviations in the display field: P → Air pressure O → Outside temperature I → Inside temperature + – Assign history NEXT Select the desired assignment using the "+" and "-" keys.
3.2. Operation Selecting the indoor temperature display In normal mode the "INDOOR" display field shows the indoor temperature and indoor humidity. - By repeatedly pressing the "IN" key, you can switch between displaying the indoor temperature and the associated dew point value: → Indoor temperature → Dew point Selecting the outdoor temperature display In normal mode the "OUTDOOR" display field shows the outdoor temperature and outdoor humidity of the chosen outdoor sensor.
Calling up MIN/MAX values The minimum and maximum values reached for the indoor and outdoor temperature and indoor and outdoor humidity since the data were last deleted are saved. For the wind speed and rainfall measurement, only the MAX values are saved. For all figures, the date and time that the extreme value occurred are also saved. The stored data can be called up as follows: Calling up minimum values - Press the "MIN/MAX" key once: The display shows all minimum values in the relevant display fields.
3.3. Additional functions Moon phase display The moon phase is displayed with the following symbols: Full moon Waning New moon Waxing Wiz Kid The Wiz Kid is an animated figure that indicates several weather factors at the same time: Outdoor temperature (combi-sensor only) - The clothing worn depends on the outdoor temperature on the combi-sensor. Rain - If the forecast function has predicted rainy weather, the figure carries a furled umbrella.
Instant rain display - The onset of rain is reported to the base station in the next radio data transmission and indicated by raindrops in the "RAIN" field and Weather Willie’s umbrella being open. Comfort indicator - The comfort indicator ( ☺) illustrates the climatic conditions (i.e. the relationship between temperature and humidity). Chapter 9 has a table of values for the display ranges. 4.
5. Information on fault removal Possible faults that could impair the correct display of the transmitted readings are: No reception – The distance between transmitter and receiver is too great. Reduce the distance between the transmitter and the receiver. No reception – Dense shielding materials are positioned between the transmitter and the receiver (thick walls, reinforced concrete, ...) Find another position for the transmitter and receiver. See also chapter 6 ("Range").
6. Range The free field range, i.e. the range of the line of sight contact between the transmitter and the receiver is 100 m under optimum conditions. Walls and even reinforced concrete can be penetrated, which does, however, reduce the range.
- Clean residue from the collector funnel, contacts, counter rocker and drain hole at the bottom of the housing. - Insert the counter rocker back into its bracket. The magnet of the counter rocker must be on the side next to the cable. - Insert the rainfall sensor into its bracket. It will automatically hold the counter rocker firmly. The cable of the rainfall sensor and the magnet of the rocker arm must be on the same side.
7.2. Calibrating the rain sensor The rainfall measuring system is delivered ex-works with a high accuracy, so that normally no calibration is required. Calibration is only necessary when very high accuracy is required.
8. Technical data Measurement interval for outdoor sensors: ..................................... approx. 3 min Measuring interval for indoor sensor: ........................................................ 10 min Transmission frequency: .................................................................... 433.92 MHz Free field range: .................................................................................. max. 100 m Indoor temperature range: ........................................................
44,6 ˚F) to say how comfortable one feels at certain temperatures and wind speeds whilst wearing appropriate clothing. These conditions are a temperature below 91,4 °F and a wind speed higher than 9,4 mph. Wind chill is defined as the cooling effect of uncovered skin at an assumed constant 91,4 °F skin surface temperature. The higher the wind speed is and the lower the actual temperature, the more noticeable is the wind chill effect.
It can be seen from this that, depending on the ratio of temperature to humidity, there are clearly bounded areas, which are defined as a comfortable or an uncomfortable climate. Hence, one finds a humidity level of 30% at a temperature of 77 °F, for example, to be too dry (e.g. heating air) and one above 60% to be sultry. 10. Intended usage, exclusion of liability, safety instructions - This weather station is intended for domestic use as an indicator of future weather.
