Note:
When putting the Weather St atio n into operation, it is
important to perform in close prox im it y (e.g. on a tab le) a
complete wiring and set-up of the system. This step is
important to test all components for correct function before
placing and mounting them at their final destinations (See
Positioning below):
1. Unwind the cables of the Wind sensor. Connect the
Wireles

2. First insert the batteries into the The r m o-hygro sensor and Rain sensor (purch as e
separately) “How t o install and replace the batteries into the Thermo-hygro
sensor“ and “How to install and repla ce the batteries into the Rain sensor
(optional)” below).
3. Then insert the batteries into the Weather C enter (see “How to install and replace
the batteries into the Weather Center” below). Once the batteries are installed, all
segments of the LCD will light up bri ef ly . It will the n di spla y the time as 12:00, the
date as 1.1.09, the weather icons, and air pr e ss ur e value. " - - -" will be shown for
outdoor data.
4. Afterwards, the Weather Center will start rec eiving data from the transmitter. The
transmission recepti on i co n will be b lin k in g to ind ic at e that t he stat i on i s trying to get
the thermo-hygro tr ansmitter data. The outdoor temperature, humidity, wind data
should then be displayed on the Weather Center. If this does not ha pp en aft e r 13 5
seconds, the batterie s will need to be removed fr om all units. You will have to start
again from step 2.
5. The transmitter reception ic on is n ow blink in g ag ain t o in d ic at e th at th e stat i on i s
trying to get the rain sensor data. It will stop blinking once the rain sensor has been
detected. If this does not happen after 135 seconds, you will need to start again from
step 2.
6. You may need to check th e cable for correct connection and all the components for
correct function by man ually turning the wind-gauge by moving the wind-vane; tilting
the rain sensor to hear the impact of the internal moving seesaw, etc. (see
Positioning below).
7. Time and date shall be manually set (See Manual Setting below).
8. After the Weather Center has been check ed for co rr e ct fun ctio n w ith re g ard to the
above points and fou nd 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. t her e a ppear to be problems with the 915 MHz radio
transmission, they can mostly be overcome by slightly changing the mounting
locations or turning the base station.
Note:
The radio communication between the receiver and the transmitters in the open field
reaches distances of max 330 feet/ 100 met er s, pr ov ided t h er e are n o inte rfe rin g ob st acl es
such as buildings, trees, vehicles, high voltage lines, etc.

9. Radio interferences created by PC screens, radios or TV sets can in some cases
entirely cut off radio communication. Please consider this when choosing standing or
mounting locations.
Note :
After batteries are installed in the transmitter, install the batteries in the weather
center to receive the signal from the t r an s mitt er s as s oo n as poss ible. I f t he w eat her
center is powered more than 5 hours after the transmitter is powered, the weather
center will never receive signal successfully from the transmitters. In this case, user
will need to reinstall the batteries from all the transmitters to redo set-up procedure.
After batteries are installed, there will be synchronization between Weather Center
and the transmitters. At this time, the signal reception icon
the signal is successfully received by the Weather Center, the
switched on. (If it is not successful, the
can easily see whether the last reception was successful (
off). On the other hand, the short blinking of the icon shows that a reception is in
progress.
If the signal reception is not successful on the first frequency (915MHz) for 45
seconds, the frequency is changed to 920MHz and the learning is tried another 45
seconds. If still not suc c essful, the reception is tried for 45 seconds on 910MHz. This
will also be done for re-synchronization.

HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE THERMOHYGRO TRANSMITTER
Note:
In the event of changing batteri es in any of the units, all units need to be reset by following
the setting up procedures. This is because a random security code is assigned by the
thermo-hygro sensor at start-up and this code must be received and stored by the
Weather Center in the fi rst several minutes of power being supplied to it.
HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE WEATHER
STATION
The outdoor Thermo-hygro tran smit t er works with 2 x AA IEC LR6,
1.5V batteries. To install and re p la ce th e bat t er i es, pl ea s e follow
the steps below:
1. Uninstall the rain cover of the transmitter.
2. Remove the battery compartment cove r.
3. Insert the batteries, observing the correct polarity (see the
marking in the battery compartm ent ).
4. Replace the battery cover and the rain cover onto the unit.
The Weather Station works with 3 x AA, IEC LR6,
1.5V batteries. When the batteries need to be
replaced, the low battery symbol will appear on
the LCD.
To install and replace the batter i es, ple a se f ol low
the steps below:
1. Remove the battery compartment cover.
2. Insert the batteries observing the correct
polarity (see the marking in the battery
compartment).
3. Replace the battery cover.
HOW TO INSTALL AND REPLACE BATTERIES INTO THE RAIN SENSOR
(OPTIONAL; SOLD SEPERATELY)
1. Unlock the main cover from the rain sensor base and remove the cover.
2. Remove the battery cover at the top of the ra in se ns or.
3. Insert 2 x AAA, IEC LR3, 1.5V batteries into the battery compartment, observin g t he
correct polarity.
4. Replace the battery cover and the main co ver o n th e unit.
Note:
In the event of changing batteri es in any of the units, all units need to be reset by following
the setting up procedures. This is because a random security code is assigned by the
transmitter and rain sensor (optional) at start-up and this code must be received and
stored by the Weather Station in the first 90 seconds of power being supplied to it.
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensur e opt i m um
accuracy of these units. (Battery life –see Specifications)
Note:
The stored History record will not be kept af t er th e battery change is done on the weather
station.
