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)
Socket for wind
sensor
1. Unwind the cables of the Wind sensor. Connect the Wind sensor to the Thermo-
hygro transmitter by plugging the connector heads into the sockets of the
Thermo-hygro transmitter.
2. First insert the batteries into the Thermo-hygro transmitter and Rain sensor (see
“How to install and replace the batteries into the Thermo-hygro
transmitter“ & How to install and replace batteries into the Rain sensor
below).
3. Then insert the batteries into the Weather Station (see “How to install and
replace the batteries into the Weather Station”below). 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 icons, and air pressure value. "- - -" will be shown for outdoor data.
77

4. Now the Weather Station will start receiving data from the transmitter and rain
sensor. The weather station will try to receive thermo-hygro transmitter data
first and then the rain sensor. Afterwards the outdoor temp should be displayed
on LCD of station. Now the reception icon is flashing, which means that the
weather station is trying to receive data at this moment. If this does not happen
after 90 seconds, the batteries will need to be removed from both units. You
will have to start again from step 1.
Note: To confirm whether the rain sensor has been received, user shall press the
SET key once to check the reception icon. Once the SET key is pressed, the
reception icon now showing will represents the reception condition of the rain
sensor.
5. The outdoor temperature, humidity windchill and wind speed should then be
displayed on the Weather Station.
6. Time and date shall be manually set (See Manual Setting below).
7. 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.

8. 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.
HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE WEATHER
STATION
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 batteries, please follow 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.

Press to unlock
1. Unlock the main cover from the rain sensor base and remove the cover.
2. Remove the battery cover at the top of the rain sensor.
3. Insert 2 x AAA, IEC LR3, 1.5V batteries into the battery compartment, observing
the correct polarity.
4. Replace the battery cover and the main cover on the unit.
HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE THERMO-HYGRO
TRANSMITTER
The outdoor Thermo-hygro transmitter works with 2 x AA IEC LR6, 1.5V batteries. To
install and replace the batteries, please follow the steps below:

1. Uninstall the rain cover of the transmitter.
2. Remover the battery compartment cover.
3. Insert the batteries, observing the correct polarity (see the
marking in the battery compartment).
4. Replace the battery cover and the rain cover onto the unit.
Note:
In the event of changing batteries 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 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 ensure optimum
accuracy of these units. (Battery life –see Specifications)
Please participate in the preservation of the environment. Return
used batteries to an authorised depot.
81

Note:
The stored History record will not be kept after the battery change is done on the
weather station.
