Note:

When putting the Weather Station into operation, it is
important to have them in close proximity (e.g. on a
table 5 ft from display) while completing wiring and set­up 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). Allow all sensors to sit with the
display for 15 minutes before mounting.

1. First, unwind the cables of the Wind sensor.

Socket for 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. Next 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 (cups); 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.

For example, if there appears 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 up to 330 feet, provided there are no interfering obstacles such as
buildings, trees, vehicles, high voltage lines, etc.

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 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.

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 CUPS ON THE BOTTOM. 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
