Rain Sensor (sold separately)

Wind Sensor

Note: When putting the Weather Station into operation,
it is important to have them in close proximity (e.g. on a
table) while completing wiring and set-up of the system.
This step is important to allow testing of 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 optional rain sensor
(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. 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 thermo­hygro transmitter data. The outdoor temperature, humidity and 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 must 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.

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 the signal successfully from the transmitters. In this case, you will need
to reinstall the batteries for all the transmitters to redo the setup procedure.

After the 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) This allows you to see whether the last
reception was successful (icon on) or not (icon off).

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 THERMO­HYGRO TRANSMITTER

Note: When changing batteries in any of the units, all units need to be reset by following

the setup procedures. This is because a random security code is assigned by the thermo­hygro 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 IN THE WEATHER
STATION

The Weather Station works with 2 x C, IEC LR14, 1.5V batteries. When the batteries need
to be replaced, the low battery symbol will appear on the LCD.

Note: When changing batteries in any of the units, all units need to be reset by following
the setup 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.

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

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.

To install or 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.

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

1

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

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
