1. General information and functioning
The WS-2510 Touch Screen Wireless Weather Station represents a high-quality, extremely
convenient universal weather measuring system, which can record, process and display data
from up to 8 external wireless temperature and humidity sensors, a wireless wind sensor, a
wireless rainfall sensor and a wireless brightness sensor.
The operating concept of the weather station is remarkable. It does not use any operating
elements, but is operated solely via a large, touch-sensitive LC display.
The display can be illuminated permanently or on a time basis, so that it can be easily read under
nearly all light conditions.
The weather station can optionally be powered by means of batteries or with the plug-in power
adaptor provided (particularly recommended when the display is continuously lit or lit for any
length of time).

Weather station connection pane, mounting arrangements and battery compartment.
The indoor/outdoor sensor system of the WS-2510 operates exclusively with wireless radio data
transfer. You can set up or mount the sensors up to 300 feet (100 m) (depending on local
conditions, see section on “range”) from the base station. Longer distances are possible using a
repeater (The repeater is available from your dealer as an option).
Some outdoor sensors derive their operating voltage from built in solar cells. Pay particular
attention to the set up and assembly instructions for these components, in order to ensure correct
orientation and operation.
2. Preparation for operation
2.1. Preparation of the weather station
The weather station runs on 4 C size 1.5V alkaline batteries. As an alternative, the station can
also be operated using the power adaptor provided. This is recommended if the station
illumination is to be used for extended periods. Battery operation is recommended particularly if
the display illumination is only used occasionally or for a short period. The picture on this page
shows the rear of the station with the battery compartment, the correct polarity of the batteries,
the stand and the hanging arrangement.
Battery operation
Remove the battery compartment cover by pressing in the two ridged areas simultaneously and
place four C size 1.5V alkaline batteries in the battery compartment in the correct orientation
according to the polarity markings. Close the battery cover.
Operation using the power adaptor
First place the round female plug of the power supply provided in the power supply socket
marked “POWER” on the rear of the unit and then plug the power supply into a 110V outlet.
When using the adaptor, any batteries that have been fitted will be switched off.
PC connection (optional)
If the station is to be connected to a PC, the PC cable (optional) must be connected by means of
the Western modular plug to the socket marked “RS 232”. The 9-pin Sub-D plug is connected to
a serial port of the PC.
Bus connection
The socket marked “BUS” is for future expansions and is not used at present.
Setting up/Wall mounting
Depending on requirements, the weather station can be hung on a vertical surface (wall) by
means of the hanging eyes or set up on a horizontal surface using the foldout desk stand. There
are two possible latching positions (45º/60º) in the hinge of the desk stand for when the unit is
mounted on the desk. When using this method, any cables that are connected should be laid
tidily in the slots of the desk stand in order to ensure an inconspicuous and orderly routing of the
cables.
Commissioning
- After the batteries have been inserted or the unit has been connected to the power supply, a
short test of all the display segments is carried out (all segments are displayed).
- Following this a short beep will be heard and the version number of the weather station will
be shown in the top left of the display.
- Next the display will go off and the weather station will go into the synchronization or
initializing mode. In this mode, a search is made for weather sensors.
- Approximately 8 seconds after the segment test, the indoor temperature and indoor humidity
will be displayed and about 4 seconds after that the air pressure. The appropriate sensors
are incorporated directly within the base station.
- The sensors (wind, rain, brightness and temperature/humidity) can now be activated. After
activation, each sensor transmits for a short period approximately for 10 minutes. This
makes it easier for reception to be checked.
- If a signal from a wireless sensor is received, a short beep will be heard, the display will go
off and then the transmitted value will be displayed.
- This initialization mode is active for 35 minutes so that commissioning of all the weather
sensors can be carried out. If commissioning is finished sooner or if the station has received
signals from all the sensors that have been installed earlier, the initialization mode can also
be terminated prematurely by touching any touch screen field.
However, this must never be done before the last sensor in the system has completed its
test run (see following description of sensors).
On completion of the initialization mode, the display goes off for approximately 1 second and
then switches to the normal display mode.
- In order to prevent an unintentional interruption of the initialization mode after inserting the
batteries and setting up the weather station (e.g. by accidentally touching the screen), the
touch-sensitive contact surfaces are blocked against any input for approximately 20 seconds
after the batteries have been inserted.
Please read these instructions carefully from start to finish before initial start
up to avoid functional breakdown and faulty operation. Keep the instructions
available for future reference.
Pay particular attention to the installation and calibration instructions for the
instruments for recording the measured values.

Please note!
Previous weather sensors with software Version 1.1.
Depending on the type and the period of manufacture, the WS-2510 system sensors are supplied
in two software versions (see printing/sticker on the sensor or the packaging). The weather
station is always set to Version 1.2 after commissioning. If you are using Version 1.1 sensors
(supplied before 5/2000), signals from these will not initially be received. However, as the
weather station can add new sensors to its sensor management at any time, it is possible to add
any sensors with software version 1.1.even retrospectively.
- When the weather station has automatically completed the initialization mode or the user
has terminated it manually, the configuration mode can be called up by pressing the
“ALARM VALUES ” key (bottom right of the control panel) for approximately 3 seconds.
- In this mode, next press the “SENSOR ADMIN ” key. The currently set version number for
the outdoor sensors will be displayed at the top left (factory setting 1.2).
- The version can be switched to 1.1 by touching this display field. In doing so however,
signals from Version 1.2 sensors will continue to be received, the weather station being
merely set up to receive signals from Version 1.1 in addition.
- When this is done, the improved transmission reliability of Version 1.2 will be lost.
- You can subsequently exit the configuration mode by pressing the “END ” key.
- The weather station now switches to normal operation, starts trying to receive signals from
all sensors for 6 minutes in the background and inserts these automatically into the sensor
administration.
2.2. The outdoor sensors
The outdoor sensors for wind and brightness measurement, for recording rainfall and for external
temperature/humidity measurement are equipped with a solar cell and a lithium backup battery to
provide power during the hours of darkness and periods of bad weather.
To prevent the batteries from discharging fully during a long period of storage without light falling
on the solar cell (e.g. when in the packaging), the power supply is activated by a small magnet
that has to be inserted from the outside before the initial start-up. Do not insert the sensor magnet
until shortly before field site assembly of each sensor. Before being used for the first time and
when the battery is discharged, sensors should be exposed to strong light for one or more days
without the activation magnet being inserted so that the backup battery is charged via the solar
cell.
After activation (insertion of the magnets, or batteries for battery supplied sensors), the sensors
transmit for 10 minutes in test mode. This means instead of the normal 3-minute scan, they
transmit during this period in a 4-second scan. This ensures optimum reception in the initialization
phase. If the signal from the sensor is unable to be received within this time, then the reception is
affected and should be improved by re-positioning the sensor.
The external temperature and humidity sensors should be addressed according to section 2.3.4.
2.2.1. Insertion of magnets into the outdoor sensors
In the WS 2510-25 and WS 2510-19 outdoor sensors, the magnet for activating the system is
pressed into an opening provided for it in the rear of the housing.
The wind sensor (WS 2510-15) is also activated by inserting a small magnet into the opening
provided. The magnet holder is located above the holding pipe fixing (opposite the solar cell).
To insert the magnet in the WS 2510-16 rain sensor press the upper section against the lower
section and turn clockwise. On the housing cover of the electronic housing incorporated into the
funnel there is a slot for the small round magnet. The rain sensor starts transmitting after pressing
the magnet into the slot.
2.3. Description, Installation and Commissioning of sensors
The WS-2510 sensor design consists of two groups of sensors. The WS 2510-19 brightness
sensor, the WS 2510-16 rainfall sensor and the WS 2510-15 wind sensor are permanently set to
address 7 in the factory. If necessary, e.g. when several sensor systems are operated in the
immediate vicinity of one another, their address can be changed in the factory.
The second group of sensors is the WS 2510-22, WS 2510-25 and WS 2510-27 types. A
maximum of eight of this type of sensor can be used and are selected using the sensor selection
on the display. Therefore each has to be assigned an address. For these types, be sure to
observe the instructions for addressing.
2.3.1 WS 2510-15 wind sensor
The wind sensor measures both the wind direction and the wind speed at the mounting location.
It is powered by a solar cell, and a back-up battery during the hours of darkness, and has a non-
user definable address.
It is mounted either on a mast or high up on a wall. It is important at the sensor location that the
solar cell in the sensor housing faces directly south and is unshielded on all sides, i.e. the wind
can reach the sensor unimpeded from all sides.
The exact alignment of the sensor to the south is very important as this alignment acts as
reference for the wind directional measuring device.
In order to obtain precise measurements ensure that the sensor is mounted vertically in the
mounting tube.
Finally screw the mounting tube and the sensor together to ensure a firm base for all the
components.
In its basic form the wind sensor should be aligned in the north-south direction (solar cell to the
south), in order to provide the precise north reference for the evaluation electronics.
2.3.2 WS 2510-16 rain sensor
The rain sensor is also powered by solar energy and has an address that cannot be changed by
the user.
In this case the alignment of the solar cell is directly towards the south.
The rain sensor should be secured to an exactly horizontal surface using the securing holes at
the base of the housing. First remove the upper part by pressing against the lower part and
turning clockwise. In the lower part is a depression that, when filled with water, permits a precise
horizontal alignment without additional assistance.
Pour a small amount of water into this depression and align the lower section of the housing
using the spirit level principle. After marking the exact installation location the water can be
removed. Note the south alignment for the solar cell. The shank of the built-in spirit level must
point to the north (see diagram).

To obtain the best possible wireless
emissions (high range) it is advisable not to
place the rain sensor directly on the ground.
By mounting the sensor about 3 feet (1m)
above the ground the danger of soiling
(especially the solar cells) is reduced.
After screwing on the lower part to the base
secure the upper part as follows:
There is a bar magnet centrally located on
the side on the counting rocker for the water
level in the base. The bar magnet initiates
the counting pulses to the electronics. The
upper part of the housing can now be placed
so that the solar cell is on the same side as
the magnet, with the electronic part directly
opposite it, with the three catches fitting
neatly into the holding devices in the lower
part. Finally turn the upper part gently anti-
clockwise until it securely slots into holding
devices of the lower part.
The rain sensor is then ready for operation.
As a test pour a little water gently into the funnel. The amount collected will then be converted in
the base unit to inches, litres/m2or mm and displayed.
2.3.3. Brightness sensor WS 2510-19
The brightness sensor detects the brightness at the current location in a range between 0 and
200000 lux. It is powered by an integral solar cell and also has a fixed address. To mount the
sensor, the plastic point is inserted on one side of the aluminum tube supplied and the sensor is
fitted on the other side of the tube. The sensor can now be inserted into the ground. Depending
on the firmness of the ground, the earth spike should be inserted so that the sensor is about 8-12
inches (20-30 cm) above the ground to avoid it becoming dirty due to mud splashing up onto it.
The sensor should be turned so that the solar cell points to the south. The location must be free
from shadows and the sun able to shine directly onto the measuring head. The sensor must be
mounted vertically with the measuring head at the top.
2.3.4 Addressing of the temperature/humidity sensors WS 2510-22, WS 2510-25, and
WS 2510-27
The outdoor sensor concept enables the
concurrent deployment of up to eight outdoor
sensors, whose data can be selected by the user
to appear in the top right hand field of the display.
Each sensor in the system is assigned a sensor
address, which enables the receiver to integrate
the sensor into the total system without any
problems. Each sensor delivered is set to sensor
1. The programmable allocation is clear from the
diagram.
The addressing can be self-generated by means
of coding bridges on the conductive side of the
sensor board. To do this on the WS 2510-25
unscrew the protective bell housing on the sensor housing and open the housing by removing the
screws on the rear.
The WS 2510-22/27 types only require the housing rear wall to be unscrewed.
The coding bridges must then be set according to the address table.
2.3.5 WS 2510-22 temperature/humidity sensor
The WS 2510-22 contains a temperature and a humidity sensor. This sensor is freely
addressable for displaying within the display field at the top right of the display (see display
overview on page 4). The addressing can be set individually according to section 2.3.4. Since it is
exclusively battery operated this sensor is suitable for use in (dark) inner rooms such as a
garage, a wine cellar or loft.
2.3.6 WS 2510-27 temperature/humidity sensor
The WS 2510-27 requires two AA alkaline batteries for operation. It enables the recording of
garden, pond or ground temperatures or similar by means of an encapsulated temperature
sensor, remotely connected to the electronics by a 9.84 foot (3 m) cable. Humidity around the WS
2510-27 casing can also be measured.
This sensor can also be freely addressed for displaying within the display field at the top of the
display (see display overview on page 4). The addressing can be set individually according to
section 2.3.4.
Now you can mount or position the electronics housing at the required location and place the
temperature sensor on or in the required object.
2.3.7 WS 2510-25 temperature/humidity outdoor sensor
The WS 2510-25 outdoor sensor enables the transmission of the temperature and humidity at the
sensor location.
This sensor can also be freely addressed for displaying within the display field at the top of the
display (see display overview on page 4). All WS 2510-25 sensors are set at the factory to sensor
1. In accordance with section 2.3.4. individual addressing is also possible.
The sensor should be mounted on the north or west side as meteorological temperature
recording normally takes place “in shadow ”. It can also be placed at other locations if desired.
You only need to make sure that the solar cell that provides the sensor with power is permanently
aligned towards the light. The sensor must not be shaded by dense obstructions such as leaves,
etc., which could impair the power supply from the solar cell. However, the solar cell does not
have to be exposed to direct sunlight. The ambient brightness is sufficient to charge the battery.
A possible location for installation is under the eaves of the roof.
The sensor is designed for wall and mast mounting and should be mounted as follows: Attach the
sensor wall bracket either exactly vertically to a wall using the four screws, or to a mast using the
securing clamp provided.
Position the sensor on the wall bracket and screw the two parts together using the screw
provided.
When doing this, the large protective bell housing must be at the top and the solar cell must be
pointing towards the light.
During the hours of darkness and periods of bad weather with relatively little sunlight an internal
battery system, which is charged by the solar cell during periods of sunshine, provides the power
for the sensor.
2.3.8 Information on the storage of solar cell powered outdoor sensors
These sensors receive their operating voltage from a solar cell that charges an internal battery to
provide power for periods of darkness and bad weather.
If one of these sensors is out of action for some time and does not receive any light this has no
affect on the internal battery, provided the magnets designed to activate the operating voltage are
removed.
Therefore the sensor can be stored for several months in its packaging, for example.
Alignment of the WS 2510-16, use of
the spirit level, and position of the
transmitter magnet

After this however, the internal battery must be charged again before being put back into
operation. To do this, the sensor must be exposed to strong light for several days without the
activation magnet in order to charge the battery via the solar cell.
3. Operation
After the installation of the wireless sensors and the subsequent commissioning of the base unit,
the transmitted and converted data appears in the appropriate fields of the display. If the displays
do not appear you will find information on fixing faults in section 5 (faults).
Please note that the only data that can be displayed is that for which the appropriate
sensors have been installed. There can be no display of rainfall without a rain sensor, for
example.
As all relevant data appears on the screen concurrently, operation is essentially restricted
to the simple selection of further sensors or weather data by gently touching the
appropriate display field.
Overview of the weather station touch screen fields.
The display is subdivided into 29 touch screen fields, which are not all active at the same time.
The touch screen fields provided in the bottom line of controls are only active when their text
appears. The appearance of the remaining touch screen fields is dependent upon the operating
mode of the station.
Every time a currently valid (active) touch screen field is pressed, a short beep will be heard. If
required, this can be switched off in the configuration mode.
3.1. Basic settings, Configuration
The weather station is delivered in a condition that allows you to use its basic functions
immediately after commissioning without further adjustment. It can be adapted to suit individual
requirements by means of further settings and configuration.
3.1.1. General settings
Illumination settings
To switch on the illumination, press any touch screen field on the display. The illumination will
now remain switched on for the programmed time (after the last key press).
As standard, the illumination is active for 10s with battery operation and continuously on when
using the AC power adaptor.
To switch off the illumination manually, press the “LIGHT OFF” key (bottom left, field 23).
The times for the illumination can be set up in configuration mode.
Cleaning mode
As the display becomes dirty in use, it must be cleaned from time to time with a dry linen cloth (a
cloth for cleaning eye glasses is most suitable, do not use cleaning fluids as the display could be
damaged). In order that the set-up of the station is not altered when wiping the display, there is a
cleaning mode where all touch screen fields are blocked for 30s.
To activate the cleaning mode, press the top right hand touch screen field “HUMIDITY” (field 6)
for approximately 4 seconds.
The display will then go off and only the time will be displayed. The display can now be cleaned.
The normal display is resumed after 30s.
Sensor reception
HF sensor synchronization takes place each morning at 7:30am for 6 minutes. During this phase,
new sensors or lost sensors are automatically recorded in the reception administration.
If a signal from a sensor is not received for approximately 12 hours (240 reception failures), then “
– – – ” will be displayed instead of the value. No further attempts will be made to receive the
signal from the sensor.
However, if the sensor should be detected again at any time, it will be re-recorded in the weather
station’s sensor administration at 7:30am (synchronization phase).
3.1.2. Configuration
Many of the weather station ’s parameters can be set up manually and individually in
configuration mode:
- Illumination time for AC adaptor operation
- Illumination time for battery operation
- Rainfall per rocker stroke
- Air pressure correction
- Temperature display unit
- Rainfall display unit
- Air pressure display units
- Key confirmation tone
- Form of presentation for the history display
- Threshold value for registering sunshine
- Setting of date and time
- Sensor administration

The configuration mode is activated by pressing touch screen field 29, “ALARM VALUES”, for 3
seconds. The following diagram shows an example of a display with the configuration mode
activated.
You can exit the configuration mode by pressing the “END” key.
Illumination time for AC adaptor operation
The illumination time for AC adaptor operation (“line”) is displayed in the “LIGHT” field (touch
screen field 1). A setting here is only meaningful when the weather station is powered by
means of the AC adaptor power supply.
The time displayed shows in hours and minutes how long the display is to remain lit after the last
touch screen field has been pressed.
A value of 0:00 means that the illumination will never come on.
A value of -:-- (appears after 9:59) means that the illumination will stay on continuously until it is
turned off manually (“LIGHT OFF” in the main display).
- Touch screen field 1 must be pressed in order to set the required ON time.
- The associated display will now flash:
- The required value between 0:00 and 9:59 as well as “-:--” can now be set using the touch
screen fields “+” and “–”. It is possible to run through the display more quickly by pressing
the relevant touch screen field for longer.
- When the required value has been set, you can exit set-up by pressing the “END” key. The
value is now stored.
Illumination time for battery operation
The illumination time for battery operation (“batt”) is displayed in the “LIGHT” field (touch screen
field 2). A setting here is only meaningful when the weather station is powered exclusively by
batteries.
The time displayed shows in seconds (up to 99) how long the display is to remain lit after the last
touch screen field has been pressed.
A value of 0 means that the illumination will never come on.
- Touch screen field 2 must be pressed in order to set the required ON time.

- By touching field 4 the display units can be switched between ºF and ºC.
Calibration of the rainfall reading indicator
The rainfall measuring system is delivered with a very high accuracy, so that normally no
calibration is required.
A calibration only becomes necessary when very high accuracy is required for
professional use or for special purposes.
Before starting the calibration of the rainfall reading indicator, set any existing summed rainfall
value in the normal display mode back to zero (see section “Rainfall measurement“).
For the exact calibration proceed as follows:
1. Allow 6.1 cu. in. of water to trickle continuously and distributed evenly into the funnel over a
period of 10 minutes. In doing so, there must be a period of at least 15 seconds between the
individual rocker movements. If the rocker tilts more quickly, the amount of water flowing
through is too great and the flow must be reduced.
2. After the water has completely run through, it is necessary to wait for a further period of 6
minutes. The total amount indicated should now be 0.3 in.
3. If a different value is displayed, then the rocker value should be recalculated as follows:
New rocker value = 0.3 x current rocker value
Actual value (display when filled with water)
The calibration value of the rainfall per rocker stroke for the rain sensor is shown in touch screen
field 8 (top center). It is always given in ml/rocker stroke, the units on the right are the units for
the subsequent display of rainfall!
and the lower touch screen field will change to the following form:
and the lower touch screen field will change to the following form:

The factory setting is 300ml/rocker stroke. Please note: This value is reset automatically after an
initialization.
- Touch screen field 8 (RAIN) must be pressed in order to set the required value.
- The associated display will now flash:
- The required value between 10 and 999 ml/rocker can now be set using the touch screen
fields “+” and “–”. It is possible to run through the display more quickly by pressing for longer.
- When the required value has been set, you can exit set-up by pressing the “END” key. The
value is now stored.
Setting the rainfall display units
The display units for rainfall are shown in touch screen field 9 on the right hand side next to the
calibration value for the rainfall. The factory setting is in inch.
- By touching field 9 the display units can be switched between inches, l/m2or mm.
Air pressure display correction
If the current relative air pressure at the place of installation is known (meteorological office,
Internet, TV weather station, etc.), this can be set up accurately. It deviates from the general air
pressure referred to sea level given in weather reports covering large areas depending upon the
height above mean sea level. You will find a detailed explanation of this in the section
“Explanation of terms”
- Touch screen field 10 (AIR PRESSURE) must be pressed in order to set the current value.
- The associated display will now flash:
- The value currently known can now be set using the touch screen fields “+” and “–”. It is
possible to run through the display more quickly by pressing for longer.
- When the required value has been set, you can exit set-up by pressing the “END” key. The
value is now stored.
Setting the air pressure display units
The display units for air pressure are shown in touch screen field 11 on the right hand side next to
the air pressure value. The factory setting is inHg.

Setting the sunshine threshold value
The set up field enables the brightness threshold to be set, above which the light striking the
brightness sensor is to be interpreted as sunshine. This threshold can be set between 1 and 99
klux and is set in the factory to 20 klux.
A value above the set value is counted as sunshine and is indicated by the little sun symbol in the
“SUNSHINE DURATION” display field.
This value corresponds to the threshold value generally used in meteorology for registering the
hours of sunshine.
- Touch screen field 19 (SUNSHINE DURATION) must be pressed in order to set the required
threshold value.
- The associated display will now flash:
- The required value can now be set using the touch screen fields “+” and “–”. It is possible to
run through the display more quickly by pressing for longer.
- When the value has been set, you can exit set-up by pressing the “END” key. The value is
now stored.
On its part, the brightness sensor also determines a sunshine duration referred to a fixed
threshold of 20 klux. If a threshold of 20 klux is set at the base station, it takes the value
transmitted by the sensor for its further calculations. The advantage of this is that breaks in
reception have no effect on the measured value.
Setting the time function
The time of day, AM/PM indication (for 12h display) is displayed in touch screen field 20.
- Touch screen field 20 must be pressed in order to make the required settings.

3.2.4. Air pressure measurement (fields 10/11)
The display field for the air pressure measurement is situated in the middle at the top right hand
side (“AIR PRESSURE”). Here, the current air pressure at the location of the weather station is
displayed with one of three possible units.
1. Depending on the setting in the configuration mode, the air pressure is displayed in hPa,
mmHg or inHg.
2. Either the relative air pressure (value corrected for height, see corresponding setting in
configuration mode and the explanation in the section “Explanation of terms”) or the
absolute air pressure (the uncorrected output value from the sensor, right hand diagram)
can be displayed.
3. Here, the “Graph” symbol shows that the trend display for the air pressure has been
selected in the history field. It only appears if it has previously been selected (see section on
“History ”).
If the air pressure history is active, then the tendency indicator for the development of the air
pressure will also appear next to it on the right.
Key functions (Allocation of touch screen fields, see page 11)
- You can switch between displaying the absolute and the relative air pressure using touch
screen fields 10 and 11.
Please note!
A difference between the absolute and relative air pressure will only be displayed when the
height-corrected value for the relative air pressure has previously been entered.
3.2.5. Weather forecast
Based on years of experience in the development of weather measurement technology, the
weather forecast algorithms for the actual operating location of the weather station are very
sophisticated and reliable. Owing to comprehensive data capture, the calculation of weather
tendencies is accurate enough for these types of devices as well, so that, for example, the
weather station will not be “fooled” by a short period of sunshine just before a long period of rainy
weather sets in.
The comprehensive nature of the forecast depends also on the location of the sensors; in flat
countryside a comprehensive forecast of this sort is possible, whereas in mountainous regions
the conditions change more frequently and are more localized.
The weather forecast is shown in the middle of the display underneath the rainfall indication by
means of easily remembered weather symbols.

Always change all the batteries and use only high-quality alkaline cells.
Please note!
After changing the batteries, the weather station will be re-initialized, all stored settings
will be lost and will have to be re-entered.
Wireless sensors WS 2510-22, WS 2510-27
The batteries in these sensors have a life of up to three years (alkaline batteries).
They must be changed when the display of the appropriate sensor in the base device display
does not appear for more than 24 hours and there is no general and longer lasting interference of
the radio path, which can usually be recognized by the fact that data transmission from other,
neighboring sensors has also broken down (see section 5,“Interference”).
The battery is changed by opening the battery compartment on the rear of the sensor housing,
removing the discharged battery and inserting two new AA alkaline batteries in the correct
polarity according to the markings in the battery compartment. Replace the battery compartment
cover and the sensor is ready for use. After a few seconds the data from this sensor will appear
on the display.
Other components of the system do not require a battery change as they are powered by
solar cells. Integrated batteries provide power during the hours of darkness and periods of
bad weather.
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 section 6 (“Range”).
Transmitter batteries are discharged.
Change batteries.
Transmitter is blotted out by a source of interference (radio device, radio head
set/loudspeaker)
Remove source of interference or find alternative location for transmitter and receiver.
A newly linked wireless sensor (e.g. after change of battery) is automatically accepted by
the system and the associated data is displayed.
Often the interference is of a temporary nature (radio telephony) or can be removed very easily. If
there are radio headsets, wireless baby phones or similar devices operating on 433MHz in your
house or in the neighborhood their turn-on time is normally limited. Most of these devices permit
change to a disturbance-free frequency.
A measure such as this effectively cuts out interference.
A wireless sensor interferes with other devices in the 433MHz range
The transmissions from a wireless sensor can interfere with other devices on the same channel
for a short period (every 3 minutes for about 200 ms).
Further information on installation and removal of interference
Under critical reception conditions the sensor test mode makes it easier to choose the best
possible location. For this purpose, the sensor concerned is put in test mode, so that every four
seconds data is transmitted.
To activate the test mode remove the batteries from the indoor sensors and the magnets from the
outdoor sensors and refit them after a delay of at least 60 seconds.
Rotate the weather station a little if required, and if reception is bad, locate it away from electric
motors, electrical machines, televisions, computer monitors and large metal surfaces.

To facilitate commissioning you can initially locate the sensors in the vicinity of the base unit (at
least 6 feet or 2 m distance). In this way you can check the correct transmission of data by the
sensor.
6. Range
The free field range, i.e. the range of the line of sight contact between the transmitter and the
receiver is 300 feet or 100 m under optimum conditions. Walls and even reinforced concrete can
be penetrated, however it will reduce the range. A reduced range can have the following causes:
- High frequency interference of all kinds
- Buildings of all types or vegetation
- The range of the wind sensor in particular can be affected by metal roofs or roof insulation
made from aluminum laminated glass wool.
- The distance of the transmitter or receiver from conductive surfaces or objects (even to
the human body or the ground) has an effect on the transmission characteristics and
therefore the range.
- Wide band interference in built up areas can reach levels that reduce the signal- noise
ratio throughout the frequency band, which reduces the range.
- Devices working on adjacent frequencies can also affect the receiver.
- Badly shielded PCs can radiate into the receiver and reduce the range.
7. Repeater for range increase
Ranges that are reduced by building parameters can be compensated for by a special repeater
developed for weather stations.
The battery-driven repeater equipped with transmitter and receiver receives the data of all
sensors and re-transmits it with a slight time delay. Housed within a watertight housing the
repeater is suitable for both indoor and outdoor mounting.
8. Maintenance and servicing information
Protect the device against dust and moisture. Never clean it with chemical cleaning materials,
use only a soft, dry linen cloth.

10. Explanation of terms
Perceived temperature -see Wind chill
Dewpoint -Temperature point that is dependent on the conjunction of a specific air pressure, a
specific temperature and a specific humidity. At this temperature, the humidity in the air begins to
condense, the so-called dew point, the humidity in the air condenses and precipitates as a liquid
(fog, steam and even spots of mildew on walls). If the dew point for water vapor is less than 32ºF,
the condensation occurs as snow or frost.
Air pressure tendency -Calculated from recent developments in air pressure values.
Absolute/relative air pressure -The air in the Earth ’s atmosphere has a specific gravity, which
is defined in grams per liter. The boundary of the Earth’s atmosphere is of a (relatively) constant
size. In contrast to this, the surface of the earth including the oceans varies between the lowest
sea level and the highest mountain peaks.
As a result of this, a different “weight” of air acts on every area depending upon the mean height
above sea level and the height of the column of air above the measuring point. The air pressure
at sea level is therefore considerably higher than that in the Himalayan peaks.
In order to provide a reference quantity, in most cases, weather reports either give the absolute
air pressure referred to mean sea level (general information, say for a country) or, in the case of
more accurate reports, the graduated air pressure represented by means of isobars (the air
pressure lines on more accurate weather maps).
In the latter case, one can easily recognize the trend of the air pressure fronts and can find out
more about the path of the fronts.
However, as the weather station always measures the absolute air pressure at its location, a
correction factor must be defined, which makes it possible to display the difference between
absolute and relative air pressure. This is achieved (with this weather station) by entering the
accurately known local air pressure (either as notified by the local meteorological office or by
calculation: absolute air pressure ±0.11hPa per meter of the measuring location above/below
mean sea level).
Wind chill equivalent temperature (perceived temperature)- A fictitious temperature, which the
human body feels under certain conditions instead of the measured temperature, and which can
be used at low temperatures (e.g. less than 45°F or 7°C) 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 (33ºC) and a wind speed higher than 5.8 mph (2.6 m/s). Wind chill is
defined as the cooling effect of uncovered skin at an assumed constant 91.4°F (33ºC) skin
surface temperature.
The higher the wind speed is and the lower the actual temperature, the more noticeable is the
wind chill effect.

The “perceived temperature” is roughly comparable to the so-called felt temperature, which
additionally takes into account the radiation effect of the sun, light refection from the clouds, the
light wavelength, etc.

The Comfort Indicator (☺"#) represents the climatic conditions, for which the following table
is used (the symbol status shows the area of validity):
Temperature Humidity
20% 30% 35% 40% 45% 50% 55% 60% 65% 70%
< 64.4°F (18ºC) ##########
64.4-67.8°F (18-19.9ºC) ###""""""#
67.9-71.4°F (20-19.9ºC) ###"☺☺☺☺"#

78.7-82.3°F (26-27.9ºC) #""""""###
over 82.4°F(28ºC) ##########
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 (25ºC), for example, to be too dry (e.g.
heating air) and one above 60% to be oppressive.
