1 General
The shipping contents of the Touch Screen Weather Station WS-3650
include a Base Station (Receiver), a Thermo-Hygro Sensor (868 MHz
transmitter), Rain Sensor (868MHz transmitter) and Wind Sensor, an
AC/DC Adapter and a PC Software Package on CD-ROM.
The Base Station is equipped with a Touch Screen LCD Monitor
and allows by use of comprehensive menu control the display of
a vast variety of time and weather data (from top to bottom):
• Radio Controlled Time (Time)
• Calendar (Date)
• Weather Forecast (Tendency)
• Air Pressure and Air Pressure History (Pressure, Pressure
History)
• Indoor Temperature and Humidity (Indoor Temp, Humidity)
• Wind
• Rain (Rain)
• Outdoor Temperature and Humidity (Outdoor Temp,
Humidity)
Furthermore the display of a number of additional data can be
realised by use of certain switching combinations (see further
down).
Note: In case the menu is used all these indications are
temporarily replaced by the menu steps directly operable
from the text section.
As an important feature exceeding the display on the LCD
Monitor the Weather Station allows by cable and software
the readout of all measured and displayed time and weather
data in form of complete history data sets, their processing
and graphic presentation on a PC as well as their tie on to
Internet Web Sites.
2 Important Touch Screen Operating Notes generally
applicable
• All actions and functions of the Weather Station are started
on the Touch Screen by slightly touching (not pressing!) the

31
switching areas appearing in star (٭) symbols (only in the
text section at the bottom of the LCD) or the displayed
values respectively.
• The setting of functions, values and units is in all modes
performed by use of the switching areas ٭ON٭or ٭OFF٭,
٭UP٭or ٭DOWN٭or by direct unit selection.
• Advancing to any next respective menu step with ٭NEXT٭,
leaving or terminating all respective modes with ٭EXIT٭.
• Every programming step activated by touching a switching
area on the Touch Screen is being acknowledged by an
acoustic signal (with buzzer switched ON).
• If during any process previously activated by use of the
Touch Screen no further action is activated for about 30
seconds the active process is automatically terminated and
switched back to the normal display mode (automatic time
out).
3 Putting into Operation
Note: When putting the Weather Station into operation it is
important to tentatively perform in close proximity (e. g. on
a table) a complete wiring and setup of the system in the
configuration of its prospective use. This measure serves
to test all components for correct function before placing
and mounting them at their final destinations.
3.1 Power supply
The provision of power to the Weather Station can be performed
by use of batteries, or by AC/DC mains adapter
1. Unwind the cable of the Wind sensor. Connect the Wind
sensor to the Thermo-hygro transmitter by plugging the
connector head into the socket of the Thermo-hygro
transmitter.
2. First insert the batteries into the Thermo-hygro transmitter.
3. Then insert batteries into the Rain sensor.
4. Insert the batteries into the Weather Station (or use the
provided AC/DC adapter (power up into a main outlet). Once
the batteries are installed, all segments of the LCD will light
up briefly and a short signal tone will be heard. It will then
display the time as 0:00, the date as 1.1.05, the weather

32
icons, and air pressure value. "- - -" will be shown for outdoor
data.
5. Afterwards, the Weather Station will start receiving data from
the transmitters. The outdoor temperature, humidity windchill
and wind speed should then be displayed on the Weather
Station. If this does not happen after 45 seconds, the
batteries will need to be removed from both units. You will
have to start again from step 2.
6. The transmitter reception icon is now blinking again to
indicate that the station is trying to receive the rain sensor
data. It will stop blinking once the rain sensor has been
detected. If this doesn’t happen after 45s, you need to start
again from step 2.
Note: if no thermo-hygro transmitter is detected, the weather
station will display the message "THERMO TX OUT OF
RANGE“; if no rain sensor has been detected, the message
"RAIN TX OUT OF RANGE“ will be display in the text section
(last two lines on the LCD).
7. You may then check all cables for correct connection and all
components for correct function by manually turning the
wind-gauge, moving the weather-vane, tilting the rain sensor
to hear the impact of the internally moving seesaw, etc (See
Placement below).
8. After the Weather Station has been checked for correct
function with regard to the above points and found fit, the
initial set up of the weather station system is finished and the
mounting of the system components can take place. It must
be ensured however that all components work properly
together at their chosen mounting or standing locations. If
e.g. there appear to be problems with the 868 MHz radio
transmission, they can mostly be overcome by slightly
changing the mounting locations.
Note:
The radio communication between the receiver and the
transmitter in the open field reaches distances of max 100
metres, provided there are no interfering obstacles such as
buildings, trees, vehicles, high voltage lines, etc.

33
9. Radio interferences created by PC screens, radios or TV
sets can in some cases entirely cut off radio communication.
Please take this into consideration when choosing standing
or mounting locations.
Important:it is important to observe this order of succession
since the sensors will send an identification code
which has to be received and stored by the Base
Station within the first few minutes of operation.
After doing this full operation of the entire Weather Station
System is ensured.
Note: If batteries are inserted in the weather station after
connecting the AC/DC, the batteries will serve as a
back-up power source for the weather station in case of
electrical failure.
3.2 System Start
After completing the play mode the Touch Screen Weather
Station will automatically switch to the normal display mode from
which all further settings can be performed by the user. At this
point of time the unit will also automatically start reception of the
DCF77 time information.
Note:In case the user wants to start the system without waiting
for completion of the play mode it can be terminated
prematurely by once touching the TIME display in the
upper left corner of the LCD.
3.3 Placement
After the Weather Station has been checked for correct function
with regard to the above points and found fit, the mounting of the
system components can take place. It must be ensured however
that all components work properly together at their chosen
mounting or standing locations. If e.g. there appear to be
problems with the 868 MHz radio transmission they can mostly
be overcome by slightly moving the mounting locations.
Note:Commonly the radio communication between receiver and
transmitter in the open field reaches distances of 100
meters maximum, providing that there are no interfering

34
obstacles such as buildings, trees, vehicles, high voltage
lines, etc.
Radio interferences created by PC screens, radios or TV
sets can in bad cases entirely cut off radio communication.
Please take this into consideration when choosing
standing or mounting locations.
The Thermo-hygro Sensor
An ideal mounting place for the thermo-hygro sensor would be
the outer wall beneath the extension of a roof, as this will protect
the sensor from direct sunlight and other extreme weather
conditions.
To wall mount, use the 2 screws to affix the wall bracket to the
desired wall, plug in the thermo-hygro sensor to the bracket and
secure both parts by the use of the supplied screw and ensure
that the cables from the wind and rain sensors are correctly
plugged in otherwise data transmission errors could occur.
The Wind Sensor

Wall Bracket

35
Firstly, check that the wind-fan and the wind-vane can rotate
freely before fixing the unit. For correct and accurate readings it
is important to mount the sensor so that the front (marked E) is
pointing in East-West direction. The wind sensor should now be
mounted using the screw or cable tie provided onto a solid wall/
panel mast or mast to allow the wind to travel around the sensor
unhindered from all directions (ideal mast size should be from
diameter 16mm to 33mm).
Once the wind sensor is fixed onto the mast, connect the cable
to the corresponding thermo-hygro sensor socket so that
operating power supply can be received and data can be
transmitted to the base station.
The Rain Sensor
For best results, the rain sensor should be securely mounted
onto a horizontal surface about 1 meter above the ground and in
an open area away from trees or other coverings where rainfall
may be reduced causing inaccurate readings.
When securing into place, check that rain excess will not collect
and store at the base of the unit but can flow out between the
base and the mounting surface (test by pouring clean water).
The rain sensor is now operable. For testing purposes, very
slowly pour a small amount of clean water into the rain sensor
funnel. The water will act as rainfall and will be received and
displayed at the base station after about 2 minutes delay i.e.
when the reading interval is reached.

from 3 hPa to 9 hPa over 6 hours (Default 5 hPa).
Activate/Deactivate storm warning alarm with ٭ON٭/ ٭OFF٭
resp. (Default OFF).

38
Relearn Mode (Relearn Tx) →Allows to clear all weather data in
non-volatile buffer memory (EEPROM) and to newly recognize
the outdoor transmitter (e. g. after a battery change in the
transmitter) without the necessity of a comprehensive re-setup of
all system components →Acknowledge with ٭CONFIRM٭.
Default Settings (Factory Reset) →Allows the reset of all set
and/or stored values to the factory settings set prior to shipment
→Acknowledge with ٭CONFIRM٭.
Note:
It will take 5 minutes for the factory reset process. During this
period, the text “Factory Reset In Progress” will be shown. After
the reset process is finished, the LCD will switch off and the text
“Remove Battery” will be displayed. Remove the battery and
perform system start again. See “3 - Putting in Operation”
paragraph.
Leaving the basic settings procedure (Setup Mode) with ٭EXIT٭.
5 Display of stored Min/Max Values and Alarm Value
Settings
Named values are in each case upon recall being simultaneously
displayed and flashing in their respective display sections.
To recall named measuring and alarm values the menu shown
below will have to be activated by touching the Touch Screen in
the center of the text display section (last two lines at the bottom
of the LCD). The display of the values is started by touching the
displays ٭MINMAX٭or ٭ALARMS٭resp.

39
The continuance of the recalling process is essentially self-
explanatory.
With ٭MINMAX٭the below shown menu step is activated, which
in return leads to the displays of the stored Min/Max values by
use of ٭MIN٭/ ٭MAX٭resp., which on their part again can be
directly selected.
Note:During individual displays of the stored Min/Max values the
top line of the LCD screen will automatically display the
time and date of their storage.
The following menu item will appear upon touching the display
٭ALARMS٭and will analog to the last described step lead
through ٭LO AL٭resp. ٭HI AL٭to the displays of the set low
resp. high alarm values, which on their part again can be directly
selected.
Because of the constant access to the respective opposite menu
item ٭MINMAX٭resp. ٭ALARMS٭it is moreover possible at any
time to toggle between the MIN/MAX and ALARMS value
displays.
Any action can immediately be terminated through ٭EXIT٭.

40
6 Radio Controlled DCF77 Clock
The Radio Controlled DCF77 Clock is normally controlled by the
radio signal of the DCF77 time code transmitter and will thus set
time and date automatically. Under bad reception conditions
however both can be set manually as follows:
Setting the Time
The action is started by touching the time display in the TIME
section of the Touch Screen.

touching the TIME section. Here the alarm symbol (((•)))
will show or disappear after ٭EXIT٭(or automatic time-
out).
7 Weather Tendency
Call up the tendency display by touching the weather symbol in
the TENDENCY section.
The text section (last two lines on the LCD) will show since when
(with time and date) the weather condition corresponds to the
presently displayed weather symbol Sunny, Fair (Cloudy with
sunny intervals) or Rainy.

42
Note:
• Up and down arrow indicate weather tendency
• Advanced storm warning is displayed by Rainy symbol
with a flashing down arrow
• Every minute, when a new pressure reading is obtained,
this value is compared to pressure readings from last 2
hours and the biggest resulting difference is displayed in
the difference barometer.
8 Air Pressure History (Pressure History)
The air pressure history shows the progress of the air pressure
over a time period of 24 or 72 hours in form of a 7-step bar
graph, where the length of the utmost right bar represents the
present air pressure and the remaining bars show the progress
of the air pressure with regard to the present air pressure.
Note:The time resolution of the bar graph can be changed from
fine (0 to -24 h) to coarse (0 to -72 h) and back by once
touching the PRESSURE HISTORY section.
9 Operating and Setting of the following Functions:
• Air Pressure (Pressure), Relative and Absolute
• Indoor Temperature (Indoor Temp)
• Indoor Humidity (Indoor Humidity)
• Outdoor Temperature (Outdoor Temp), Wind Chill, Dew
Point
• Outdoor Humidity (Outdoor Humidity)
• Wind Speed,Wind Gust

43
Important Note!
Since operating procedures and settings are identical all
steps to be carried out on the Touch Screen Weather Station
for above functions shall be explained only once by means
of the following example “Air Pressure”.
9.1 Air Pressure (Pressure)
Example for Activating the Displays of Stored Maximum
Values
Call up the menu on the text section by touching the PRESSURE
section.
Start with ٭MAX٭in the menu section.
Note:Display of the stored minimum values is from here
possible through ٭MIN٭analog to this example.
Display of stored value. Proceed with ٭MAX PRESSURE٭.
Resetting of the displayed value to the present value with
٭CONFIRM٭.
Without resetting advance with ٭EXIT٭.
End of Example
Example for Setting of Alarms by means of the HI Alarms
As in the example above here too call up the menu on the text
section by touching the PRESSURE section.
Start with ٭ALARM٭in the menu section.

44
Proceed with ٭HI AL٭in the menu section.
Note:Setting of the LO alarms is from here possible through ٭LO
AL٭analog to this example.
Setting of high alarm value with ٭UP٭or ٭DOWN٭.
Proceed with ٭ON/OFF٭.
Activate or deactivate the alarm with ٭ON٭or ٭OFF٭.
Terminate with ٭EXIT٭.
Note:Activation or deactivation of the alarm (Display or deletion
of the (((•))) symbol) only pertains to the respective
presently displayed value.
End of Example
Note:Twice touching the PRESSURE section toggles the
displays of the Relative (rel) and Absolute (abs) air
pressure.
All setting and display facilities only pertain to the
respective presently displayed value.
10 Operating and Setting of Function Rain
Note:Besides the direct setting of the units for the rain amount in
the basic setup procedure there is the possibility to toggle
between the following displays by twice touching the left
part of the RAIN section:

45
• Rain amount of the last hour
• Rain amount of the last 24 hours
• Rain amount of the last week
• Rain amount of the last month
Note: The rain amounts of the last week and of the last
month do not represent the amounts collected up to
the present point of time but those of the last
complete week or the last complete month
respectively.
All setting and display facilities only pertain to the
respective presently displayed value.
Important Note!
Operation and settings of the function Rain are essentially
corresponding to the ones described in Item 9 above.
Therefore a short description of the trivial differences with
regard to Item 9 should be sufficient.
• Since in the display function Rain the display of minimum
rain values is unnecessary, the menu does not offer the item
٭MIN٭but ٭MAX٭only to display the various maximum rain
amounts.
• Since because of the above no minimum alarms are
necessary the menu will upon activating ٭ALARM٭avoid Hi
AL resp. LO AL selection and immediately proceed to the HI
alarm setting as already described in Item 9 above.
Note: The setting facility for the alarms is only offered during
display of the rain amounts of the last hour resp. the one of
the last 24 hours. Since for the rain amounts of the last
week resp. the last month no exact definition for the alarm
time is possible the alarm function has been omitted.
• When touching the display TOTAL in the RAIN section the
total rain amount accumulated since the last deletion is
displayed. This can be erased through ٭RAIN TOTAL٭,
followed by ٭CONFIRM٭.

46
11 Additional Information to Function Outdoor
Temperature (Outdoor Temp)
Note:By twice touching the OUTDOOR section the display will
toggle between the following:
• Outdoor Temperature (Outdoor Temp)
• Wind Chill
• Dew Point
All setting and display facilities only pertain to the
respective presently displayed value.
12 Additional Information to Function Wind
Note:By twice touching the WIND section the display will toggle
between the following:
• Wind Speed
• Wind Direction (Abbreviations of the compass card
descriptions)
• Wind Direction (Degrees)
• Wind Gust
All setting and display facilities only pertain to the
respective presently displayed value.
12.1 Operating and Setting of Function Wind Direction
In the display function Wind Direction the display of minimum or
maximum values is unnecessary. There is however the
possibility to realize wind direction alarms.
Start the menu in the text section by touching the center of the
WIND section.
Proceed with ٭DIR AL٭.
In the following menu up to 16 separate alarms can be realized
(depending on the basic setup clockwise around the compass
card from N via NNE etc. through NNW or from 0°via 22.5°etc.
through 337.5°). Here the wind direction can be selected with

47
٭UP٭or ٭DOWN٭and switched ON or OFF with ٭(Wind
Direction) ON/OFF٭in the upper left part of the menu display.
Activation or deactivation of every respective wind direction
alarm with ٭ON٭or ٭OFF٭in the menu step shown below.
Leaving the mode with ٭EXIT٭.
13 Operating and Setting of Functions EL Backlight
(Light), Buzzer and Alarm in the WIND Section
13.1 EL Backlight (Light)
For better readability of the LCD the EL backlight can be
switched ON or OFF by once touching the LIGHT section. In
condition ON the backlight will be switched on for approximately
15 seconds every time any one of the LCD sections is being
touched.
The switching condition (Enabled/Disabled) is shown in the text
section for about 30 seconds.
Note:In case the Touch Screen Weather Station is battery
operated the repeated use of the EL backlight will result in
a considerable decrease of battery lifetime. It is thus
recommended to either operate the Weather Station on
the included AC/DC adapter or entirely deactivate the EL
backlight (see above).
13.2 Buzzer
The buzzer for the acoustic acknowledgement or alarm signals
of the Weather Station can be switched ON or OFF by touching
the BUZZER section.
The switching condition ON or OFF is displayed directly in the
BUZZER section as well as for about 30 seconds in the text
section (Enabled/Disabled).
