WS 250 - Weather Station TECHNOLINE - Free user manual and instructions

USER MANUAL WS 250 TECHNOLINE

The weather station WS 250 Edition is a high-quality universal weather measuring system which processes a large quantity of weather data and additional information, and displays the current weather as well as weather forecasts. All relevant data are displayed simultaneously on the LC display. Additional data can be called up at the push of a key. A special feature is „Weather Willie“. He indicates the current temperature range of the by means of the clothes he wears, the current wind speed with his hair and scarf and the forecast and starting or current precipitation. The forecasts of the base station serve only the purpose of orientation. They do not represent an absolutely true forecast. The manufacturer does not assume any responsibility for incorrect displays, measuring values or weather forecasts or any consequences which may result from these. The product is intended for private use. It is not suited for medical purposes or public information. The components of this product are not toys. Install all components in such a way that children have no access to them. The product is battery-operated. All external sensors transmit their data per radio to the base station (868 MHz, range up to 100 m in open space, see chapter 12 on page 52). Any other use than that described above may lead to damage to the product or to other danger. Read the complete operating manual carefully. It contains much important information about the installation and operation.37

The behaviour of this figure depends on several weather factors so that you can tell at a glance which clothes you can wear if going outdoors. This not only evaluates the current measuring values for the outdoor temperature, air humidity, wind and rain. The weather forecast also plays an important role here. Depending on the weather situation, „Weather Willie“ has a different appearance and wears different clothing. „Weather Willie“ shows several weather factors at one glance:

• Weather Willie’s clothing depends on the outdoor temperature measured by means of the combination sensor.

• In the case of wind speed in excess of 20 km/h, Weather Willie’s hair will blow in the wind. If the temperature is below 15 °C at the same time, his scarf will also blow in the wind.

• If the weather forecast forecasts rain, Weather Willie will carry a (closed) umbrella.

Damage caused by non-observance of this operating manual can lead to forfeiture of the warranty! We shall not assume any liability for subsequent damage! We shall not assume any liability for damage to items or persons caused by improper handling or non-observance of the safety instructions! In such cases, any guarantee claims shall become null and void . Dear Customer, the following safety and hazard notices not only serve the protection of your health but also the protection of the appliance. Please read the following points carefully! Do not use this product in hospitals or medical institutions. Although the outdoor sensor only emits relatively weak radio signals, these may cause interference to life-support systems. The same can also apply in other areas. The weather station is only suited for dry, indoor premises. Do not expose it to direct sunlight, extreme heat, cold, dampness or humidity. If used correctly, the rain/wind detector is suited on the other hand to unprotected outdoor locations. For safety and licensing reasons (CE), it is not permitted to convert or modify the product. Do not leave the packaging material lying around. Plastic foil and bags, polystyrene parts etc. are dangerous toys in the hands of children. Handle the product with care! Blows or impact, or dropping it even from a small height will damage it.

6. Battery and environment instructions

• Batteries do not belong in the hands of children.

• Observe the right polarity when inserting the batteries/accumulators.

• Do not leave batteries lying around. Pets or small children may swallow them. If they are swallowed, contact a doctor immediately.

• Leaking or damaged batteries/accumulators may lead to injury to the skin. For this reason, use suitable protective gloves when changing them.

• Make sure that batteries or accumulators are not thrown into the fire or short-circuited. There is a likelihood of explosion!

• Never dismantle batteries/accumulators!

• Do not recharge normal batteries. There is a risk of explosion!

• If the product is not used for longer periods of time (e.g. in case of storage), please remove the inserted batteries/accumulators in order to prevent damage caused by leaking batteries/ accumulators.40

7. Preparation for operation, commissioning

Please observe:First of all, put all available outdoor sensors into operation (insert batteries)and then the base station itself.If you proceed in the opposite order, it could occur that the base station doesnot detect all the existing outdoor sensors.We always recommend you to first of all try out the base station with all outdoor sensors (in asmuch as you have purchased additional outdoor sensors besides the supplied combinationsensor) in a room before installing the outdoor sensors in the open air. However, the distancebetween the base station and the out-door sensors should be at least 2 m in order to avoidinterference.If you notice that one outdoor sensor is out of range after installation, you can assume that radioreception is not sufficient (and that there is no defect in the outdoor sensor).This initial function test will save extensive and time-consuming error searches afterwards. a) Commissioning the combination sensor

• Open the casing of the sensor. First of all, turn the lower casing cover slightly in the directionof the arrow (1) as shown below and then carefully lower the casing cover.• Now insert three batteries (LR6/mignon/AA) with the correct polarityinto the battery compartment (see illustration below on the right).Use preferably alkaline batteries.Accumulators can also be used but these reduce willreduce the range due to the lower voltage / capacity aswell as their operating life!For the first 5 minutes the combination sensor is in a test mode andsends its data-telegrams in an intervall of approx. 3 seconds. Aftercompletion of the test mode the normal transmission interval ofapprox. 155 seconds is activated.It must be guaranteed that the combination sensor has alreadyleft its test mode when the synchronisation mode of the basestation is terminated, otherwise a normal reception isn’t possible.• Close the sensor casing, slide the cover to the top and lock it again.• Assemble the installation base.As already explained above, you should first of all install the sensorsin the garden etc. after a successful initial function test.It may be difficult to find a favourable place for the combination sensoras this should stand preferably in the shade in order to measure thecorrect temperature. On the other hand, it is also necessary toconsider the functions of the wind and rain sensor.Closeness to buildings, trees, etc. may impair the measuring valuesof the wind and rain sensor.

below41 Once you have found a favourable location, insert the earth peg deep into the ground in order to ensure the stability of the combination sensor. When selecting the installation site, take the safety of children, pets, vehicles, etc into consideration. Any risk of the combination sensor’s falling poses the risk of injury or danger of damaging vehicles or other objects. You can also use a hammer to insert the earth peg into the ground. However, use a suitable piece of wood or similar in order not to damage the top end of the pipe as this makes it impossible to connect the other pieces of pipe (loss of warranty)! Make sure that there are no pipes or similar installed in the area where you wish to insert the peg into the ground (e.g. hoses for irrigation systems or similar). b) Commissioning additional sensors If you wish to use one or several additional temperature / humidity sensors of the type „ASH2200“, insert the batteries now into the sensor(s) with the right polarity. You can operate up to 8 sensors. c) Commissioning the base station

• Open the battery compartment on the back of the base station (remove the installation base, if applicable).

• Insert four batteries (LR6/mignon/AA) with the correct polarity into the battery compartment. Use preferably alkaline batteries. It is possible to use accumulators but these reduce the operational life due to their lower voltage / capacity.

• Close battery compartment.

• After you have inserted the batteries, all segments of the LCD are displayed briefly.

• After that, the base station activates the synchronisation mode for 15 minutes. During this period, the device displays all received radio weather sensors in succession. If all sensors used have already been received, you can terminate synchronisation mode prematurely by pressing any key. It must be guaranteed that the combination sensor has already left its test mode, otherwise a normal reception isn’t possible. In case of doubt the synchonisation mode of the base station should not be terminated manually.

• Normal display of all weather data takes place after synchronisation. Only the sunset and sunrise together with the moon phase are not yet displayed because the time and the calendar have to be set for this purpose.

• You can either hang the base station on a wall (there is a corresponding opening on the back) or place it on a level surface with the installation base.

• If you want to use the foot, first put the front central spike of the foot into the supports on the back side of the base station. Then, swing the foot a little bit back till the two rear spikes lock into the catch supports at the buttom of the base station.

9. Configuration and Operation

After installation of the radio sensors and the subsequent commissioning of the base station (this order must be observed!), the data transmitted by the radio sensors should appear on the LC display of the base station. a) Basic Settings, configuration The following settings are still required for operation:

• Year, month, day, hour, minute

• Latitude/longitude of your position

• Time zone You will then see the display of the moon phase and the sunset/sunrise as well as the date and the time. Additional settings:

• Rain sensor alignment is possible on request (however, this was already carried out by the manufacturer so that it normally does not have to be repeated!)

• Unit of rain quantity

• Assignment of progress display (air pressure, interior or exterior temperature)

• Wind strength unit The keys have the following functions in configuration mode: Imprint Function Description IN (unused) SENSOR EXIT leaving configuration mode MIN/MAX + increase value RAIN - decrease value OUT NEXT to next setting You will also find the key allocation on the back of the weather station. Please observe: The values are adjusted more quickly if you press the keys „+“ or „-“ longer when making individual settings. After each setting, you can leave the configuration mode by pressing „EXIT“ or move on to the next setting using the key „NEXT“. Configuration takes place in the sequence: Year Month Day Minute Hours Latitude Longitude Time zone (ti) Rain sensor alignment Rain unit quantity Assignment of progress display Wind unit After that, the setting order commences from the beginning again.

• in chapter 18 on page 61, you will find a table with the coordinates of several German cities. Select a nearby location near and enter its coordinates.

• if you have a GPS navigation device, e.g. in your car or a mobile device, you can adopt its position details and thus the exact position.

• you can also obtain the exact co-ordinates in the Internet. There are numerous sites that deal with navigation. Please observe the fact that the information concerning the sunrise / sunset would only be correct to be exact at the sea of for completely level landscape. Mountains, high forests etc. will alter these values for your location. Even for the ideal situation, the information can deviate by some minutes as an approximation formula is used for the calculation.

• Winter time + 1 Enter the current value for your time zone using the keys „+“ and „-“. All settings have been made at this time for correct operation of the weather station. The extended settings are not required for normal operation. Now press „EXIT“ to leave the configuration mode and return to normal mode. Now the base station is back in normal mode. Press the key „NEXT“ to make extended settings and go to the balancing of the rain sensor. Entering the alignment value The rain gauge has been set to a high degree of accuracy ex works so that you normally do not need to align it. Simply press „NEXT“ to take over the factory settings. Otherwise the alignment value will have to be determined first of all in normal mode (see chapter 13 d) on page 56). Enter the previously determined alignment value using the keys „+“ and „-“. Press „NEXT“ to set the unit for measuring rain.

alignment value NEXT47 Selecting the unit for rainfall measurement The unit for the rainfall quantity is displayed in the field „RAIN“ where you can chose between l/m

or mm. Select the desired unit using the keys „+“ and „-“. Press the „NEXT“ key. After that, you can allocate the progression display. Allocating the progress display You can allocate the following display types to the graphic progression display:

• atmospheric pressure

• interior temperature

• exterior temperature If the progress display is allocated to one of the two temperature displays, the symbol „ “ appears in the display field con- cerned in addition. Overlay/identification in the display field: P = atmospheric pressure O = outdoor temperature I = indoor temperature Select the desired allocation using the keys „+” and „-”. Press the key „NEXT“, after that, the unit for the wind velocity measurement can be entered. Selecting the unit for wind velocity The following units can be set: km/h = kilometre per hour m/s = metre per second mph = miles per hour The display will take place in the field „WIND”. Select the unit with which you wish to display the wind velocity using the keys „+” and „-”. If the „NEXT“ key is pressed, the year will appear again; the input order can commence from the beginning again. You could now, for example, monitor or alter the entries. Terminating configuration mode Press „EXIT” to complete input. This can take place at any desired position, e.g. after setting the time etc.

EXIT48 b) Operation Selecting indoor temperature display In normal operation, the indoor temperature and internal humidity are displayed in the display field „INDOOR”. By repeatedly pressing the „IN” key, you can switch between:

• respective dew point Selecting outdoor temperature display In normal operation, the indoor temperature and internal humidity of the selected outdoor sensor are displayed in the display field „OUTDOOR”. By repeatedly pressing the „OUT” key, you can switch between:

• temperature measured (wind chill) Selecting outdoor sensor In the display field „Sensor”, the outdoor sensor selected at the moment concerned is displayed together with its sensor number. Only active (in the synchronisation phase) sensors are displayed. To select the outdoor sensors or combination sensors, press the „SENSOR“ key so long until the desired sensor number appears:

• for outdoor sensors 1-8, the sensor number concerned (1-8) is displayed

• no sensor number is displayed for the combination sensor, the overlay „SENSOR“ (alongside the outside humidity) disappears. Selecting rain quantity display period By repeatedly pressing the „RAIN“ key, you can switch between:

• display of the total quantity since the last clearance of the rain quantity after inserting the batteries. In the process please consider the following peculiarities: The calculation of the rain quantity „last hour“ always occurs at the half-hour, for example between 2.30 p.m. and 3.30 p.m. The calculation of the rain quantity „last day“ always occurs at 7.30 a.m. The rain quantity „current hour/day“ results from the quantity, that accumulates till the next half-hour, for example 4.30 p.m. Deleting total rain quantity Press „RAIN“ key for approx. 2 seconds. After releasing the key, the total rain quantity is deleted. Displaying MIN-/MAX figures (extreme values) For the measurement figure of the indoor/outdoor temperature and indoor/outdoor humidity, the minimum and maximum figures reached since the last clearance of data are stored. Only the MAX figures are stored for the wind velocity and rain quantity measurements. The point of time and date of incidence of the extreme value are also stored for all figures.

Pressing the „MIN/MAX“ key switches between the display of the minimum values, the maximum values and the normal display. Proceed in retrieving the stored date as follows:

• Retrieving minimum values Press the „MIN/MAX” key. „MIN“ appears in the centre. The minimum values are now overlayed in the displays concerned. No display takes place for wind and rain (minimum value would always be „0“).

• Retrieving maximum values Press the „MIN/MAX” key once again (starting from the normal display press the key twice). „MAX” appears in the display in the centre. The maximum values are displayed in the display fields concerned.

• Returning to normal display By pressing the „MIN/MAX” key, return to the normal display takes place, the overlay „MAX“ disappears from the display. Displaying time/date for individual extreme values If necessary, you can have the appropriate time or date of incidence displayed for each individual extreme value. Proceed as follows:

• First of all, select the display of the minimum values (press „MIN/MAX” key once, overlay „MIN“ in the LCD) or the maximum values (press „MIN/MAX” key twice , overlay „MAX“ in the LCD).

• The desired value can now be displayed by pressing the „SENSOR” several times. Order of display: indoor temperature indoor humidity outdoor temperature outdoor humidity rain quantity (only MAX value, not for „TOTAL“) wind velocity (only MAX value) Only one display field is displayed with its extreme value at one time; the point of time and date of incidence of the extreme value appears below in the time display.

• Pressing the „SENSOR“ key again leads back again to the complete display of all extreme values (MIN or MAX according to whether you have selected the minimum or maximum values at the beginning). Deleting MIN/MAX values Press the „MIN/MAX“ key once to display the minimum values or twice to display the maximum values. Now you can choose the value to be deleted by pressing the „SENSOR“ key. To delete the values displayed (either minimum values or maximum values), press the „RAIN“ key for more than two seconds. After that, the figures are deleted.

c) Other functions Moon phase display The moon phase display appears with the following symbols: The moon phase display only appears when the time/date have been entered. Weather Willie „Weather Willie“ displays several weather factors at once as an animated figure:

• Outside temperature (only combination sensor) Weather Willie’s clothing is altered through the outside temperature on the combination sensor.

• Rain If the weather forecast function has registered „rain“, a closed umbrella is displayed. If the combination establishes rain, the umbrella is put up.

• Wind velocity For wind velocities of over 20km/h, Weather Willie’s hair blows in the wind. If the temperature is under 15 °C at the same time, the scarf displayed also blows in the wind. Weather forecast The symbols of the weather forecast from the weather station right at the top of the display give the following forecasts: Overcast with rain rainy Overcast cloudy Overcast with sun bright Sun sunny Wind symbol display (windsock) The windsock symbol in the display field „WIND” shows at a glance whether the wind is at present light, moderate or strong: Windsock hanging light wind (< 10 km/h) Airsack half raised moderate wind (10...20 km/h) Airsack horizontal strong wind (> 20 km/h) Immediate rain display The combination sensor determines not only the rain quantity but also transmits the current status (dry/wet) of a special sensor. Through this, even one drop can be transmitted to the base station as „beginning rain“. In the LC display of the base station, a symbolic rain drop appears in the field „RAIN“. Apart from this, „Weather Willie“ puts up his umbrella. Waning New-moon Waxing Full-moon

Comfort indicator The comfort indicator reflects the climate in the room (ratio of temperature to humidity). You can find a table of values for the display areas in section 15 on page 58. The comfort indicator displays three different smiles:

Graphic progression display (history) The bar chart shows the last 24 hours’ progress of atmospheric pressure, outdoor and indoor temperature. The individual columns represent no absolute value, but the difference to the current measurement (0-hour column). This point of reference is always situated in the center (4 bars), so that the tendendy can be interpreted at first glance.

10. Changing battery

Depending on which batteries or accumulators you use, the replacement interval can be very different. High-quality alkaline batteries keep the longest, accumulators for cheap zinc-carbon batteries require more frequent changing. a) Base station If the battery flat symbol appears in the display ( ), the batteries have to be replaced by new ones.

• Always replace the whole set of batteries.

• Do not mix full with „half-full” batteries“.

• Always use four batteries of the same type and manufacturer.

• Do not mix batteries with accumulators.

• As already mentioned, accumulator operation is possible, the durability is, however, appreciably lower than with batteries.

• For changing the batteries, proceed as described in section 7. c). Please observe the following: After replacing the batteries, all data, values stored in the base station (e.g. time, date etc.) are deleted and have to be entered again. b) Combination sensor, outdoor sensor When the display of the sensor concerned fails for more than 24 hours, the batteries are to be replaced with new ones as described in section 7. a) and b). Check as whether there is possibly some disturbance in the radio transmission which is the cause for the failure of the data transmission. In this case also, there will be no indication in the display of the base station. The cause could be, for example, a metal object in the radio path (e.g., a parked vehicle).

Observe the safety instructions contained in these operating instructions Problem Remedy No reception • The distance between the base station and outdoor sensors is too great. Alter the position of the outdoor sensors.

• Objects or shielding materials are obstructing the radio reception. Alter the position of the outdoor sensors and the base station.

• The batteries of the outdoor sensors are too weak or flat. Insert new batteries into the sensors as an attempt.

• Another transmitter on the same or neighbouring frequencies is disturbing the radio signal of the outdoor sensors. This can be, for example, radio headphones, radio loudspeakers or similar devices. Such products are not usually operated constantly; the radio reception can, for example, be perfect the next day; this makes the search for the cause more difficult. If possible, set another frequency on the instruments which can eliminate the reception problems of the weather station. Disturbance of • The outdoor sensors transmit their data to the base station approx. other instruments every 3 minutes for a period of 0.1 (100ms) seconds. In this short through the outdoor period, disturbances in other devices are also possible. sensors For example, a very short disturbance signal can be audible from a radio head phone every 3 minutes. Problems with the • When inserting the batteries into the outdoor sensors and the base synchronisation station (observe this order exactly!), these devices are in synchronisation mode. A data telegram is transmitted here every 4 seconds which accelerates the recognition and registration of the outdoor sensors at the base station. To enforce new synchronisation, remove the batteries from the base station and outdoor sensors. After that, wait at least 60 seconds before you insert the batteries into the outdoor sensors again and, lastly, into the base station (observe this order without fail – first of all insert the batteries into all existing outdoor sensors, only then into the base station. In doing so, however, all values/data which the base station has stored (e.g. minimum values, maximum values and date/time etc.), are lost.

• Before you position the outdoor sensors, for example in your garden, carry out a function test as described at the beginning of

The transmission range of the radio signals to the base station is 100 m under optimum conditions. This is often described as the „free field range”. This ideal arrangement (e.g. base station and outdoor sensor on a smooth, level field without trees, houses etc.) is, however, never found in practice. Normally, the base station is set up in the house, the combination in the garden and further outdoor sensors, for example in ancillary buildings (e.g. in an aviary) or garage. The range can be reduced considerably partly through:

• walls, reinforced steel ceilings

• coated/vapoured insulation glass panes

• trees, bushes, earth, rocks

• closeness to metal & conductive objects (e.g. radiators)

• closeness to the human body

• broadband disturbances, e.g. in residential area (DECT telephones, mobile telephones, radio head-phones, radio loudspeakers, other radio weather stations, baby phones etc.)

• closeness to electric motors. Transformers, network parts pr computers

• closeness to poorly shielded or openly operated computers or other electrical devices As the local circumstances are different at every place of set-up, a certain range cannot be guaranteed. If the base station is receiving no data from the combination sensor or any additionally existing outdoor sensors (in spite of new batteries), reduce the distance between the outdoor sensors and the base station, change the place of set-up . Observe section 7 and 11 of these operating instructions.

13. Maintenance and cleaning

a) General Check the technical safety of the product regularly, e.g. damage to the housing. It can be assumed that operation is no longer ensured without risk if

• the device shows visible damage

• the device is no longer functional

• after longer periods of storage under unfavourable conditions or

• after heavy transport stress Before cleaning or servicing the device, observe the following safety instructions without fail: Remove the batteries before cleaning, servicing or carrying out repair work. There are no parts in the interior requiring servicing; the device may not be opened. Repairs may only be carried out by a specialist who is familiar with the associated hazards and relevant regulations for the device. b) Cleaning base station Dust can be removed very easily with a vacuum cleaner and a clean, soft brush. Keep the opening of the vacuum cleaner close to the base station (do not come into contact, scratching possible!) and remove the dust with the brush. The dispersed dust will be sucked in by the vacuum cleaner. Use a soft, dry, lint-free cloth for cleaning the exterior of the product. For greater contamination, you can use a cloth slightly moistened with warm water. Never use aggressive cleaners or chemical solutions as the surface of the device or its functionality could be damaged as a result. c) Cleaning outdoor sensors or combination sensor After a longer period of operation in the open air, dirt can gather on the plastic surface of the outdoor sensors. This can be removed very readily with a soft cloth which has been moistened with water. Never spray the outdoor sensors with, for example, a garden hose as the outdoor sensors are only protected against rain from above and not against water jets from the side or from below. The rain gauge should be monitored from time to time.55 Depending on the location, leaves, particles of dirt carried by the wind, small twigs and similar can enter the cone collector of the rain gauge. Large parts can clog the flow-through! Sand can also collect in the count rocker which will affect the measuring result negatively as it increases. For this reason, the rain gauge should be cleaned at least once a year. Proceed as follows:

• open the lower part of the rain gauge. To do this, turn the lower part approx. 1 cm to the left until you can let the metal nips slide downwards.

• remove the upper cone collector by turning it first of all a small distance to the right; then lift it off to the top.

• the rainfall sensor (the plastic part with the two brass pins and cable) can now be removed. Make a note of the orientation; the connection cable of the rainfall sensor can be found at one side.

• Remove the count rocker. Make a note of the orientation; there is a small magnet at one side of the count rocker.

• Now clean the components of the rain gauge. Think also of the drain hole in the plastic lower part of the rain gauge which you have pushed downwards at the metal pipe.

• To reassemble, place the count rocker first of all in the holder. For this, the magnet of the count rocker has to belocated on the side which points to the cable. The two lower trapezoid pins have to be inserted into the lower part of the holder correctly. Only in this manner is it guaranteed that the count rocker can be moved easily.

• Insert the rainfall sensor into its holder. It will hold the count rocker firmly automatically. Only one orientation is correct; the cable of the rainfall sensor and the magnet of the count rocker have to be on the same side; the plastic nib on the other side has to be inserted precisely into the holder, look at the circle in the picture on the right.

• Place the cone collector from the top onto the sensor carrier and snap it in by turning it to the left.

• Push the lower part of the rain gauge housing upwards and lock it by turning it to the right until it snaps in. The drain holes in the lower part of the housing have to point to the outside so that the water does not run on to the metal stands.

d) Aligning rain sensor The measuring system of the rain gauge has already been set ex works to a high level of exactitude. Any alignment is therefore normally not necessary. The alignment process takes fairly long (at least 10 minutes) and has to be carried out very exactly and conscientiously as, otherwise, the exactitude is much lower than that which already exists. Proceed as follows for alignment:

• First of all, set any rain quantity value which may have accumulated back to zero. For this, press the „RAIN“ key in normal display mode for about two seconds. After releasing the key, the display of the total rain quantity must indicate „0“.

• Make sure that the rain gauge is clean and the count rocker dry.

• Pour 100 ml of clear water very slowly (distributed over 10 minutes) into the cone collector of the rain sensor. CAUTION! If the water is poured too quickly, it results in an inaccurate measuring result. Pour the water into the cone so slowly that at no point of time water stands in the cone.

• If any other value is displayed, the so-called rocker value is to be recalculated as follows:

6.5 x current rocker value

New rocker valuet = Actual value (display after filling with water)

• This new value has to be entered in the configuration menu (see section 9. a), „enter alignment value of rain sensor“) . It is always entered in ml/rocker beat, the unit on the right is the subsequent display unit of rain quantity! The setting ex works is 295 ml/rocker beat (the ”current rocker value“ for the formula above).

Observe all the safety precautions in these operating instructions! a) General The product may not be opened or taken apart (except for the work described in these operating instructions, e.g. change of battery or cleaning the rain gauge). There are no parts to be maintained by the user in the inside of the product. The product will be damaged even if dropped from a low height. b) Base station Avoid the following adverse ambient conditions during operation or transport: - moisture or excessive humidity - extreme cold or heat direct sunlight - dust or flammable gases, vapours or - heavy vibration - strong magnetic fields, such as, for example, in the vicinity of machines or speakers Never use the product immediately if it has been taken from a cold area to a warm area. The condensation developing could in certain cases destroy the device. Wait until the base station has reached room temperature. This can take some hours! A place for set-up has to be selected so that the base station stands securely and cannot fall down. There is danger of injury due to its extreme heaviness. Valuable or easily scratched furniture surfaces should be protected from damage by suitable mats before setting up the base station. c) Combination sensor Although the combination sensor is protected against rain from above, this is not the case, however, from the side or from below. Therefore, avoid any direct spraying, for example, through a garden hose or another watering system. Select the place of set-up so that children cannot tip the combination sensor over; do not place the combination sensor in the proximity of vehicles, glass doors, windows or similar!59

Sensed temperature See „windchill“. Comfort indicator The symbol of the comfort indicator (the three different „smiles“ ☺ ) reflect the room climate whereby the weather station works according to the following table: Temperature moisture 20% 30% 35% 40% 45% 50% 55% 60% 65% 70% <18°C

Independent of the ratio temperature to humidity, there are clearly delimited areas which are defined as comfortable or uncomfortable climate. For example, you feel humidity of under 30% to be too dry at a temperature of 25° C (e. g. heating air) and humidity of over approx. 60% to be humid. Dewpoint This concerns a temperature which is dependent on the coincidence of a certain air pressure, a certain temperature and a certain humidity. The condensation of the humidity begins at this temperature point, the co-called thaw, the humidity condenses and comes down as liquid (mist, vapour). If the melting point for water vapour lies at below 0° C, condensation will take place as snow or frost. Weather forecast The weather forecast of the weather station takes place by means of various weather symbols which are calculated from the rising or falling speed of the air temperature (tendency). This speed of change in the air temperature is the decisive volume for forecast of the approaching weather, the absolute value plays a sub-ordinate role here. In general you can say that increasing air pressure signalises better weather while falling air pressure, on the other hand, means poor weather. Windchill (equivalent temperature, sensed temperature) The human being feels temperatures under certain circumstances quite differently from what a thermometer can show. In the case of low outdoor temperatures, you sense the temperature on the naked skin as being much lower the quicker any additional wind blows.60 The „windchill“ is defined as a cooling down effect on the naked skin with a theoretical surface temperature of 33°C and a wind velocity of over 2.6 m/s. The higher the wind velocity is and the lower the actual environment temperature, the more the windchill effect can be felt. The „sensed temperature” is approximately comparable to the so-called felt temperature which, in addition, amongst other things, also takes into consideration the radiation effect of the sun, the light reflection of the clouds, the light wave length etc. Wind strength table (Beaufort) Beaufort Wind velocity Description 0 0 - 0.7km/h calm 1 0.7 - 5.4 km/h light draught 2 5.5 - 11.9 km/h light breeze 3 12.0 - 19.4 km/h weal breeze 4 19.5 - 28.5 km/h moderate breeze 5 28.6 - 38.7 km/h fresh breeze 6 38.8 - 49.8 km/h strong wind 7 49.9 - 61.7 km/h stiff wind 8 61.8 - 74.6 km/h stormy wind 9 74.7 - 88.9 km/h storm 10 89.0 - 102.4 km/h heavy storm 11 102.5 - 117.4 km/h gale-force storm 12 > 117.4 km/h hurricane

a) General Dispose of the unusable product according to valid legal regulations b) Disposing of used batteries and accumulators You, as ultimate consumer, are required by law (battery regulations) to return all used batteries. Disposing of used batteries with domestic waste is prohibited! Batteries / accumulators containing toxins are marked by appropriate symbols which refer to the prohibition of disposal with domestic waste. The designations for the decisive heavy metals are: Cd = cadmium, Hg = mercury, Pb = lead (The designation can be found on the battery under the dustbin symbol illustrated on the left). You may return used batteries/accumulators free of charge to collecting stations, our outlets or anywhere else where batteries/accumulators are sold. By doing so, you fulfil the legal requirements and contribute to the conservation of our environment.61
