Note:

When putting the Weather Station into operation, it is important to completely setup the wiring and rest of the system in close proximity (e.g. on a table 5ft from display) and test 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 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 plugging the connector head into the socket of the Thermo-hygro sensor.

OPTIONAL Wireless transmission at 915 MHz – Rain sensor to weather station

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. 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 should check the cable for correct connections and test all the components for correct functionality by manually turning the wind-gauge and by moving the windvane; 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 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/ 100 meters, 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 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 the signal is successfully received by the Weather Center, the switched on (If it is not successful, the

icon will not be shown).

 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

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 air flow 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 air flow 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 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 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:

When 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. (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.
