1. Intended Use
The Weather Station WS 200 is a high-quality universal weather measuring system which is able
to process a large number of weather data and additional information and can indicate both
current values and forecasts.
All relevant data are simultaneously presented on the LC display, further data can be indicated
by pressing a key.
A special feature is the figure of the ”Weather Willi”. The clothes he wears show the current
outdoor temperature range, his hair and scarf reflect the range of the current wind speed and
his umbrella indicates prognosticated rain.
The forecasts of the basis station are to be considered orientation values. They do not represent
an absolutely accurate prognosis. The manufacturer does not take over any responsibility for
incorrect indications, measured values or weather forecasts and the consequences thereof.
This product is designed for private use and is not suitable for medical purposes or for informing
the public.
The components of this product are not a toy, they contain fragile glass and ceramic parts.
Set up all the components in such a manner that they are out of the reach of children.
The product is operated by batteries. All external sensors transmit their data to the base station
via radio in the range of 868 MHz (coverage up to 100m in the free field).
Use other than that described above will lead to damage to the product.
Please read the complete operating instructions before use. They contain important
information for correct installation, functioning and operation.

”Weather Willi” weather indicator
Following the almost forgotten weather house, in which a person with an umbrella steps out of
the door in case of bad weather and a person lightly dressed appears in case of good weather,
the WS 200 is provided with the ”Weather Willi”.
The behaviour of this figure depends on various weather factors so that you can see at a glance
which dressing you should put on if you want to go outside.
This indicator does not only reflect the current measured values for outdoor temperature, air
humidity and wind, but also the weather forecast data.
Therefore, many different presentations and kinds of clothing of ”Weather Willi” are
provided and shown according to the weather situation.
•The clothing of ”Weather Willi” depends on the outdoor temperature measured at the
multipurpose sensor and ranges from swimming shorts up to the complete winter dressing
including a cap, a muffler and gloves.
•At wind speeds higher than 20 km/h (moderate wind) the hair of ”Weather Willi” blow in the
wind and if he has put a muffler on – dependent on the temperature, too – it also blows in the
wind.
•If the weather forecast predicts rain, the ”Weather Willi” will take his umbrella with him.

5. Safety Instructions
The warranty will lapse for damage due to non-compliance with these operating
instructions. We shall not be held liable for any consequential damage or loss!
We shall not accept liability for damage to property or personal injury caused
by incorrect handling or non-compliance with the safety instructions. Any claim
to warranty will lapse in such cases.
Dear Customer, the following safety and risk instructions are intended not only for the
protection of your health but also for the protection of the device. Please read through the
following points attentively:
Do not use this product in hospitals or medical institutions. The outdoor sensor does only emit
relatively weak radio signals. These radio signals could, however, lead to malfunctions in life-
supporting systems. The same may possibly apply to other areas.
The weather station is only designed for dry rooms. Do not expose it to direct sunlight, high
temperatures, coldness or excessive dampness and humidity.
The multipurpose sensor (and separately/additionally available outdoor sensors) is suitable for
operation in non-protected outdoor areas.
For safety and licensing (CE) reasons, unauthorised conversion of and/or modifications to the
product are not permitted.
Do not leave packaging material lying around carelessly. Plastic foil/bags and polystyrene parts
etc. could become dangerous toys for children.
Handle the product with care. It can be damaged through impact, blows or by being dropped
even from a low height.

6. Battery and Accumulator Information
•Batteries/accumulators must be kept out of the reach of children.
•Make sure that the batteries/accumulators are inserted with the correct polarity.
•Do not leave the batteries/accumulators lying around in the open; there is a risk of their being
swallowed by children or domestic animals. If swallowed, immediately contact a doctor.
•Leaking or damaged batteries/accumulators can cause burning if they come into contact with
the skin. For this reason you should use suitable protective gloves.
•Make sure that batteries/accumulators are not short-circuited or thrown into a fire. There is
a risk of explosion!
•Never dismantle batteries/accumulators!
•Batteries may not be recharged. There is a risk of explosion!
•In case of longer periods of non-use (e.g. during storage) remove the inserted batteries/
accumulators to avoid damage by a leaking battery/accumulator.
•Always replace the whole set of batteries/accumulators. Do not mix batteries/accumulators
of different types/manufacturers.
•Never mix batteries with accumulators!
Please note:
The weather station, multipurpose sensor and possibly used outdoor sensors can be
operated by accumulators. However, due to the lower voltage of accumulators
(accumulator = 1.2 V, battery = 1.5 V) the operating life can be decreased. Moreover,
the radio coverage will be reduced, in rare cases even malfunctions can be caused.
Therefore, the following rule applies:
If you face any problem during the operation based on accumulators, use batteries
instead of them. We recommend you to operate the weather station, multipurpose
sensor and possibly existing outdoor sensors only with high-quality alkaline batteries.
Please refer to chapter 16 for the environmental-friendly disposal of batteries
and accumulators.

11
7. Preparation and Start-up
Please note:
First start up all provided sensors (multipurpose sensor and possibly existing
outdoor sensors) (insert batteries) before starting up the weather station itself.
If you fail to follow this order of proceeding, it may be that the base station is
not able to identify the provided sensors!
It is principally recommended to test the base station with all its sensors (supplied multipurpose
sensor and possibly existing outdoor sensors) first in a room, before installing the sensors
outside.
The distance between the base station and the sensors must be at least 2m to avoid
interference. Do not place the sensors side by side, but install them throughout the
area (e.g. if you have purchased several additional sensors).
If you find out that one of the sensors is not received after the installation, you can take it for
granted that the radio reception is too weak.
You avoid complex and time-consuming troubleshooting, if you perform this first functional test.
a) Start-up of the Multipurpose Sensor
•Open the housing of the multipurpose sensor. First, turn
the lower cover of the housing a little bit towards the arrow
as shown on the right (1) and then pull it carefully
downwards (2).
•There are two options to mount the sensor on a mast:
1. Own installation mast, e.g. purchased in the DIY
superstore
2. Optionally available installation mast matched to the
system (not included in the scope of delivery, is to be
ordered separately)
Fig. 1

12
Proceed as follows for mounting:
1. Own individual installation mast
supplied
mounting rod
supplied shaped
aluminium part
mounting clip
installation mast
Fig. 2a
•Screw out the two small screws at the bottom
of the multipurpose sensor a little bit.
•Insert the supplied mounting rod of 25cm
from into the multipurpose sensor the bottom
in such a way that the two holes in the mounting
rod are directly positioned under the screws.
•Then tighten the two screws carefully (screws
are to be screwed into the holes of the
mounting rod).
•The mast required must have a diameter of
between 25mm and 45mm. It can either be a
free mast or a mounting angle, e.g. for a
satellite dish.
•Position the shaped aluminium part on one
side of this mast/mounting angle and put a
hose band clip over the two parts.
•Set the short mounting rod of the sensor against the other side of the shaped aluminium part
(on the right side in Figure 2 above) and tighten the hose band clip by using a screwdriver.
2. Optionally available installation mast (not included in the scope of delivery)
If you want to drive the rod with the flat tip (serves as an earth tip) into the ground by
means of a hammer, use a suited wooden clump in any case to protect the mast.
Otherwise, the upper end of the rod will be damaged (installation of the sensor mast
will not be possible any longer), guarantee will lapse!
•Assemble the single parts of the sensor mast. Plastic couplers combine the individual rods.
plastic coupler
Fig. 2b
•The flat rod end serves as an earth tip.

13
•After the installation of the mast, insert three batteries (AA/
Mignon) with the correct polarity into the battery compart-
ment. You will find the corresponding image in the battery
compartment (see also figure 3 on the right).
If possible use alkaline batteries.
As already described in chapter 6, accumulators
can be used, too. They, however, can have a
negative influence on the operating life, coverage
and operational safety.
•During the following 5 minutes, the sensor is in the so
called synchronisation mode in which it sends one data
package every 4 seconds.
During this period of time you should insert the batteries
into the base station so that it can identify the sensor.
Fig. 3
•Then close the housing of the multipurpose sensor again, slide the cover upwards and lock
it by turning it to the right (reverse direction than shown in Fig. 1).
•To avoid unnecessary long ways for checking the functions, the final positioning, e.g. in the
garden, should be performed only after a successfully completed functional test as described
at the beginning of this chapter.
The correct location of the multipurpose sensor is decisive for obtaining the most accurate
measuring values.
The temperature sensor inside the housing of the multipurpose sensor is positioned
at the top below the ”umbrellas” in a ventilated area of the housing. Therefore, in
direct sunlight only a slightly higher temperature value will be measured.
Please ensure that the wind sensor at the tip of the multipurpose sensor is not
positioned too close to houses, trees etc., because this could falsify the measured
values of the wind speed.
That’s why, the multipurpose sensor should be set up in a free space, e.g. in the
garden.
•The mast must firmly stick in the soil with the multipurpose sensor being positioned
approximately 2 m above the ground.
When selecting the place of installation, consider the safety for children, pets,
vehicles etc.
If the multipurpose sensor falls down, there is risk of injury or damage to
vehicles or other objects.
Make sure that there are no pipes (e.g. hose pipes for irrigating systems or
similar) at the place where the earth rod is inserted/driven into the ground.

14
b) Start-up of Other Sensors
If you want to use several additional temperature/air humidity sensors suited to the Weather
Station WS 200, insert the batteries into the sensor(s) now. A maximum number of 8 of such
sensors can be operated.
The installation, addressing and start-up of the sensor is to be performed according to their
operating instructions.
c) Start-up of the Base Station
The base station is designed to indicate all registered and calculated data on a clearly arranged
LC display. The sensors for indoor use (temperature, air humidity, air pressure) are also included
in the housing of the base station.
For this reason, ensure during the start-up or installation of the base station that a heating or
ventilation system (e.g. an air-conditioning system) is not in its proximity, because false data
could be indicated in such a case. Avoid direct sunlight, too!
Keep to the following order of steps during the start-up:
•Open the battery compartment on the back side of the base station (remove the foot first, if
necessary!).
•Insert four batteries (AA/Mignon) in the battery com-
partment paying attention to the correct polarity. You
will find the corresponding image in the battery
compartment (see also figure 4 on the right).
If possible use alkaline batteries.
As already described in chapter 6, accumu-
lators can be used, too. They, however, can
have a negative influence on the operating
life, coverage and operational safety.
•Close the battery compartment again.
•If the batteries are inserted, all segments of the LC
display will be shown briefly.
Fig. 4
•Afterwards, the base station activates the synchronisation mode for 15 minutes. In this period
of time all sensors received will be indicated one after the other.
If all your installed sensors have already been received, you can cause a premature
exit of the synchronisation mode by pressing any button, provided that all sensors
have already completed their own synchronisation mode.
If you face any problem in the identification of one sensor, you should wait as long
as the synchronisation time is finished. This process takes 15 minutes.

15
•After the synchronisation, the normal display of all weather data is shown.
Only sunrise and sunset as well as the phase of the moon have not been indicated
yet, because time and data are to be set before.
•Configure the base station as described in chapter 9 ”Configuration and Operation”.
•The base station can either be hung up on the wall (a suited opening is provided on the back
side) or placed on a foot onto a surface.
If you drive a nail into the wall or drill a hole for a plug with screw for this
purpose, pay attention that no power, gas or water pipes can be damaged,
grave danger!
•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 bottom of the base station.
d) Registration of Sensors during Normal Operation
When starting up the product, all available suited sensors are registered at the base station in
the synchronisation mode and then received during normal operation
(time required for the synchronisation of the base station takes about 15 minutes after inserting
the batteries, time required for the synchronisation of the sensors takes about 5 minutes after
inserting the batteries).
To register further new, additionally purchased sensors (or sensors lost during the battery
replacement) you do not need to follow the procedure of the initial start-up.
All data saved (minimum and maximum values, time etc.) would be lost during this
kind of proceeding.
Every day, the base station performs a synchronisation test at 8 a.m. and 6 p.m. so that it can
identify new sensors (or a sensor with battery replacement) automatically.
But if the new sensor is not indicated, the problem may be found in the coverage (see
chapter 12 ”Coverage”).

9. Configuration and Operation
When the batteries have been inserted into the sensors and the batteries have been inserted
subsequently into the base station (this order is to be strictly followed), the data transmitted via
radio by the sensors should appear in 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 and longitude degrees of your location
•time zone
Only after these settings, the phase of the moon, MIN-/MAX-data and the sunrise/
sunset times as well as the date and time will be indicated.
Additional setting options:
•assignment of the march indication (air pressure, indoor or outdoor temperature; standard:
air pressure)
•unit of the temperature measurement (standard: °C)
•unit of the wind speed measurement (standard: km/h)
In the configuration mode the keys have the following functions:
Imprint Function Description
IN (not used, no function)
SENSOR - Decrease value
MIN/MAX EXIT Exit the configuration mode
RESET + Increase value
OUT NEXT Go to next setting
This key layout is also given on the back side of the weather station.

Entering the degrees of latitude/longitude
The entry of the location of the weather station is required
for the calculation of sunrise and sunset times.
The degree of latitude can be entered in the range from -
60.0°to +60.0°.
The degree of longitude can be entered in the range from
0.0°to 360.0°.
The position of Berlin is programmed by the manufac-
turer.
You can determine your location in different ways:
•You find a table with the coordinates of the most important
German towns in the chapter ”Position Table”. Select a
town close to you and enter its coordinates.
•If you possess a GPS navigation device, e.g. in your car
or a mobile one, you can take over its location information
and then you have your exact position.
•You can also get the exact coordinates via the Internet.
It provides numerous pages which contain information
on navigation.
Please consider the fact that the data for sunrise or sunset
are only exact at the sea or for a totally even landscape.
Hills, high forests etc. alter these values for your location.
Even for ideal positions the data may vary by some minutes,
because an approximation formula is used for the calculation.
Set the degree of latitude via the + and -keys.
For example: 52.5°, entry: 525
Press the NEXT key. Afterwards, the degree of longitude
can be entered. In the display these data are indicated by
LO (= longitude).
Set the degree of longitude via the +and -keys.
For example: 13.4°, entry: 0134
Press the NEXT key. Now, set the time zone. ”ti” is faded
into the display.
