SETTING UP:

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

3

1. Unwind the cables of the Wind sensor. Connect the Wind sensor to the Thermo­hygro transmitter by plugging the connector head into the socket of the Thermo­hygro 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. 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, provided there are no interfering obstacles such as
buildings, trees, vehicles, high voltage lines, etc.

4

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.

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 thermo-hygro 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 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.

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:

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 (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 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.

Important Notes:

After you have followed the aforementioned set-up procedures, please read the
main manual for the following important functions of the weather center in detail:

 Viewing wind/ rainfall and air pressure data
 Viewing Max/ Max weather data
 Viewing History data record

Mounting the units:

Using 915MHz wireless transmission gives users little restriction on placement because all
units can be positioned virtually anywhere within a 330 ft / 100 meters radius of the base
station. Please ensure that the cable included in this set meets your distance
requirements (see accessories in the main user manual for adding extension cables).

Important: Ensure all signals can be received and/or all cable distances meet with your
requirements at the point of fixing particularly before you start drilling any mounting holes.

Wind sensor

Secure the main unit to the shaft of the mast holder using the single screw provided with
the front of the sensor (marked E) facing in the East-West direction otherwise wind
direction will not be accurate. Now fix the entire unit to a suitable mast using the U-bolt,
washers and nuts found in this set.
Note: For best results mount the wind sensor onto a mast to allow the wind to freely travel
from all directions to enable an accurate reading (ideal mast size should be from Ø

5

/8” to

1

1

/4”). Ensure that the cable of the wind sensor meets your distance requirements

16

Thermo-hygro Sensor

To wall mount the thermo-hygro sensor, fix the wall holder onto the desired wall (2 screws
are supplied), plug the sensor firmly into the wall holder and then carefully replace the rain
cover back over the thermo-hygro sensor.

Note: After mounting the units, should the weather data not be received, user may need to
remove the batteries from all units and redo the set-up procedures after about 5 minutes.

Rain sensor (optional)

The rain sensor should be mounted horizontally about 2-3ft off from the ground (or higher)
in an open area away from trees or other coverings to allow rain to fall naturally for an
accurate reading.

Note: For best results ensure the base is horizontal to allow maximum drainage of any
collected rain
