SET UP:
NOTE:
When first operating the Weather Station, it is important to
completely set-up the wiring and rest of the system in close
proximity (e.g. on a table 5ft-10ft from display) and test all
components for correct function before mounting them at
their final destinations (See Positioning below) (Allow all
sensors to sit with the display unit for 15 minutes before
mounting)
1. First, unwind the cables of the Wind sensor. Connect
the Wind sensor to the Thermo-hygro transmitter by
Socket for wind
sensor

plugging the connector head into the socket of the Thermo-hygro sensor. Be sure
the cord “clicks” into place.
2. Next, insert the batteries into the Thermo-hygro sensor and Rain sensor (optional -
purchased separately) See “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. 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 should check the cable for correct connection and test all the components for
correct functionality by manually turning the wind-gauge and by moving the wind-
vane; tilting the optional rain sensor to hear the impact of the internal moving seesaw,
etc. (See Positioning below).
7. Time and date must be manually set (See Manual Setting below).
8. After the Weather Center has been tested and found fit, the initial set up of the
weather station system is finished and the mounting of the system components can
take place. Ensure that all components work properly together at their chosen
mounting or standing locations before permanent mounting.
For example, if there appears to be problems with the 915 MHz radio transmissions,
they can often 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 up to 330 feet/ 100 meters, provided there are no interfering
obstacles such as buildings, trees, vehicles, high voltage lines, etc.

8
9. Radio interferences created by cordless phones, 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, you
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).
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.

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. Remove the airflow 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 airflow cover onto the unit.
NOTE:
When changing batteries in any of the units, all units need to be reset by following the
setting up procedures. This is because the thermo-hygro sensor at start-up assigns a
random security code 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 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
(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 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.
NOTE:
When changing batteries in any of the units, all units need to be reset by following the
setting up procedures. This is because the transmitter and rain sensor (optional) assign a
random security code at start-up and these codes 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. (For battery life information, see the Specifications section)
Please participate in the preservation of the environment. Return used
batteries to an authorised depot.
NOTE:
The stored History record is lost when a battery change is done on the weather station.
