Note:
When putting the Weather Station into operation, it is
important to perform in close proximity (e.g. on a table) 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
Wind sensor to the Thermo-hygro transmitter by
plugging the connector head into the socket of the
Thermo-hygro sensor.

2.
First insert the batteries into the Thermo-hygro sensor and Rain sensor (purchase
separately) “
How to install and replace the batteries into the Thermo-hygro
sensor
“ and “
How to install and replace the batteries into the Rain sensor
(optional)
” below).
3.
Then insert the batteries into the Weather Center (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 briefly. It will then display the time as 12:00, the
date as 1.1.09, the weather icons, and air pressure value. "- - -" will be shown for
outdoor data.
4.
Afterwards, the Weather Center will start receiving data from the transmitter. The
transmission reception icon will be blinking to indicate that the station is trying to get
the thermo-hygro transmitter data. The outdoor temperature, humidity, wind data
should then be displayed on the Weather Center. If this does not happen after 135
seconds, the batteries will need to be removed from all units. You will have to start
again from step 2.
5.
The transmitter reception icon is now blinking again to indicate that the station is
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 the cable for correct connection and all the components for
correct function by manually 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 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 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 meters, provided there are no interfering obstacles
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 transmitters as soon as possible. If the weather
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 will be blinking. When
the signal is successfully received by the Weather Center, the icon will be
switched on. (If it is not successful, the icon will not be shown in LCD) So the user
can easily see whether the last reception was successful ( icon on) or not ( icon
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 successful, the reception is tried for 45 seconds on 910MHz. This
will also be done for re-synchronization.
