1. Intended use
The weather station WS 250US 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 „Wiz Kid“. He indicates the current temperature range by means of the
lothes 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 (433 MHz, range up to 100 m in open space, see chapter 12 on page 23).
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.

„Wiz Kid“
Reminiscent of the almost forgotten weather house in which case a person with an umbrella
comes out in case of bad weather and another one with light clothing in case of good weather,
the WS 250US Edition has „Wiz Kid“.
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,
„Wiz Kid“ has a different appearance and wears different clothing.
„Wiz Kid“ shows several weather factors at one glance:
• Wiz Kid’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, Wiz Kid’s hair will blow in the wind. If the tem-
perature is below 15 °C at the same time, his scarf will also blow in the wind.
• If the weather forecast forecasts rain, Wiz Kid will carry a (closed) umbrella.
• If it starts raining, Wiz Kid will carry an open umbrella.
b) Combination sensor
• Radio transmission of:
- rain quantity
- immediate rain detection
- wind velocity
- temperature
- humidity

5. Safety instructions
Damage caused by non-observance of this operating manual can lead to forfeitu-
re 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.

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 does
not detect all the existing outdoor sensors.
We always recommend you to first of all try out the base station with all outdoor sensors (in as
much as you have purchased additional outdoor sensors besides the supplied combination sensor)
in a room before installing the outdoor sensors in the open air. However, the distance between
the base station and the outdoor sensors should be at least 2 m in order to avoid interference.
If you notice that one outdoor sensor is out of range after installation, you can assume that radio
reception 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 direction
of the arrow (1) as shown below and then carefully lower the casing cover.
• Now insert three batteries (LR6/mignon/AA) with the correct polarity
into the battery compartment (see illustration below on the right).
Use preferably alkaline batteries.
F
1
2
++
+
–

below
Accumulators can also be used but these will reduce
the range due to the lower voltage / capacity as well as
their operating life!
For the first 5 minutes the combination sensor is in a test mode and
sends its data-telegrams in an intervall of approx. 3 seconds. After
completion of the test mode the normal transmission interval of
approx. 155 seconds is activated.
It must be guaranteed that the combination sensor has already
left its test mode when the synchronisation mode of the base sta-
tion 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 sensors
in the garden etc. after a successful initial function test.
It may be difficult to find a favourable place for the combination sen-
sor as this should stand preferably in the shade in order to measure
the correct temperature. On the other hand, it is also necessary to
consider the functions of the wind and rain sensor.
Closeness to buildings, trees, etc. may impair the measuring values
of the wind and rain sensor.

10
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, for example of
the type „ASH 2200US“, 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.

Entering latitude/longitude
It is necessary to state the location of the weather station in order to calculate the sunset/sunrise
times. You can enter the latitude at a range of between -60.0° to +60.0°.
The manufacturer’s setting is Washington D. C.. You can determine your position in different ways:
• in the appendix A on page 33, you will find a table with the coordinates of all US counties
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 coordinates 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 or 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.

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, „Wiz Kid“ puts up his umbrella.
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 29.
The comfort indicator displays three different smiles: J K L
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
or cheap zinc-carbon batteries require more frequent changing.

If the battery flat symbol appears in the display ( ), the batteries have to be replaced by
new ones.
