SETTING UP:

Wireless transmission

at 915 MHz - thermohygro and rain sensor to the Weather Center

Rain sensor

Note:

When putting the Weather Center into operation, it is important to perform in close proximity (e.g. on a table) a compl e te 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 fina l destinations (See Positioning below) Spin the wind vane and tip the rain gauge to test.

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 Rain sensor “How to install and replace the batteries into the Thermo-

hygro sensor“ and “How to install and replace the batteries into the Rain sensor” below).

3. Then insert the batteries into the Weather Center (see “How to install and replace the batte ries into the Weather Center” below).

Once the batteries are installed, all segmen ts of the LCD will light up briefly and a short signal tone will be heard. It will then display the time as 00:00, the date as 1.1.05, the weather icons, and air pressur e 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 pl ace. It must be ensured h owever 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.

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 aft er 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 frequenc y

(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 SENSOR

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 RAIN SENSOR

The rain sensor works with 2 x AAA, IEC LR3, 1.5V batteries. To install and replace the batteries, please follow the steps below:

1. Press tabs back to unlock rain sensor cover. (Figure 1)

2. Lift rain sensor cover to access battery compartment. (Figure 2)

3. Insert the batteries, observing the correct polarity (see the marking in the battery compartment). (Figure 3)

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 rain sensor at start-up and this code must be received and stored by the Weather Center in the first several minutes of power being suppl ied to it.

The outdoor Thermo-hygro sensor 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.

BATTERY CHANGE:

It is recommended to replace the batteries in all units every 24 months to ensure optimum accur acy of these units.

Please participate in the preservation of the environment. Return used batteries to an authorized depot.

Note:

The stored History record will not be kept after the battery change is done on the Weather Center.

RELATIVE PRESSURE REFERENCE VALUE SETTING

Note:

The default reference pressure value of the barometer is 29.91inHg when batteries are first inserted. For an exact measurement, it is necessary to

first adjust the barometer to your local relative air pressure (related to elevation above sea level). Ask for the current atmospheric pressure of

your home area (Local weather service, www, optician, calibrated instruments in public buildings, airport).

The relative air pressure can be manually set to another value within the range of 27.17 to 31.90 inHg (919 to 1080 hPa) for a better reference.

Flashing

1.The current relative pressure value will start flashing

2.Use the + or MIN/MAX key to increas e o r decrease the value. Continually holding the key will allow the value to increase faster.

3.Confirm with the SET key and enter the WEATHER TENDENCY SENSITIVITY VALUE SETTING.

Note:

This feature is useful for those who live at elevations above sea level, but want their air pressure display to be based on sea level elevation.
