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

69
Socket for wind
sensor
them at their final destinations (See Positioning below). Spin the wind vane and tip
the rain gauge to test.
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. Cord should “click” into place.
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 00:00, the date as 1.1.05, the weather
icons, and air pressure value. "- - -" will be shown for outdoor data.

70
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 45 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 45 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 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.

71
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.
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.

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.
HOW TO INSTALL AND REPLACE BATTERIES INTO THE RAIN
SENSOR
The rain sensor works with 2 x AAA, IEC LR3, 1.5V Alkaline batteries. To install and
replace the batteries, please follow the steps below:
1. Press tabs back to unlock rain sensor cover. (Figure 1)
Figure 1
Figure 2 Figure 3

73
2. Lift rain sensor cover to access battery compartment. (Figure 2)
3. Insert the batteries, observing the correct polarity (see the marking in the battery
compartment). (Figure 3)
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 rain sensor at start-up and this code must be received and stored by
the Weather Center in the first several minutes of power being supplied to it.
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. Remove 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
several minutes of power being supplied to it.

74
BATTERY CHANGE:
It is recommended to replace the batteries in all units every 24 months 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.
Note:
The stored History record will not be kept after the battery change is done on the
weather station.
