Weather Center

Wind Sensor

When putting the Weather Center 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 compo n ents for correct function before placing and mounting them at their final destinations (See Positioning below)

1. Unwind the cables of the rain and the wind sensors. Connect the rain and the wind sensors to the thermo-hygro sensor by plugging the connector heads of the two sensors into the appropriate sockets of the thermo-hygro sensor.

2. First insert the batteries into the thermo-hygro sensor (see “How to install and replace the batteries into the thermo-hygro sensor“ below).

3. Then insert the batteries into the Weather Center (see “How to instal l and replace the batteries into the Weather Center” below). Once the batteries are installed, all segments of the LCD will light up briefly and a short signal tone will be heard. It will then display the time as 12:00, the date as 1.1.05, the weather icons, and air pressure value. "- - -" will be shown for outdoor data.

Sockets for wind and rain sensor

4. Afterwards, the Weat her C enter will start receiving data from t he se nsor. The outdoor temperature, humidity wind chill and wind speed should then be displayed on the Weather C e nter. If this does not happen after 30 s eco nd s, the batteries will need to be removed from both units. You will have to start again from step 1.

5. You may then check all cables for correct connection and all compone nts for correct function by manually turning the wind-gauge, moving the weather-vane, tilting the rain sensor to hear the impact of the internally moving seesaw, etc (See Positioning below).

6. Time and date shall be ma nu ally set (See Manual Setting below).

7. 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 Center system is finished and the mounting of the system components can take place. It must be verified, however, that all components work properly together at their chosen mounting or standin g l o c ations. 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.

Note:

The radio communication between the receiver and the sensor 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.

8. Radio interferences created by PC screens, radios or TV sets can in some cases entirely cut off radio communication. Please take this into consideration when choosing standing or mounting locations.

Note:

The thermo-hygro sensor should be placed in a dry, shaded area. The temperature sensor has a range of 330 feet. Keep in mind that the 330 feet is in open air with no obstructions and that radio wa ves DO NOT curve around objects. Actual transmi ssion range will vary depending on what is in the path of the signal. Each obstruction (roof, walls, floors, ceilings, thick trees, etc.) will effectively cut signal range in half.

Example: A Professional Weather Ce nter with a 330 feet range is mounted on an interior wall, so that the signal has t o pa ss through one interior wall, one exterior wall, and across the 10 feet width of the room be tw een the 2 walls. The first wall will reduce the range to 165 feet, and the second wall will reduce the range to 87 feet. Factoring in the 10 foot room, this leaves a maximum of 77 feet of remaining signal range.

This allowance is typically enough for a frame wall with non-m etallic siding; however certain materials can reduce range even further. Metal siding, stucco, and some types of glass can reduce signal range by as much as ¾ or more, compared to the ½ reduction typical of most obstructions. It is possible to receive a signal through these materials, however maximum range will be much less due to their tendency to absorb or reflect a much larger portion of the se ns or’s signal

Note :

• After batteries are instal led in the sensor, install th e b atteries in the Weather

Center to receive the signal from the sensor as soon as possible. If the Weather Center is powered more than 5 hours after the sensor is powered, th e Weather Center will never recei ve signal successfully from this sensor. In this case, user will need to reinstall the batteries from the sensor to redo set-up procedure.

• After batteries are installed, there will be synchronization between Weather

Center and the sensor. 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 14

seconds, the frequency is changed to 920MHz and the learni ng i s tried another 14 seconds. If still not successful the reception is tried for 14 seconds on 910MHz. This will also be done for re -sync hronization.

HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE WEATHER CENTER

The Weather Center 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:

Sensor signal reception icon

HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE THERMO-HYGRO SENSOR

The outdoor thermo-hygro sensor works with 2 x “AA”, IEC LR6 1.5V batteries. To install and replace the batteri es, 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. Uninstall the rain cover of the sensor.

2. Remover the battery compartment cover.

3. Insert the batteries, obs erv i ng 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 batteri es i n any of the units, all units need to be reset by following the setti n g u p pr oc edures. This is because a random security code is assigned by the thermo-

hygro sensor at start-up and this co de must be received and stored by the Weather Center in the first 30 seconds of power bei ng supp li ed to it.

BATTERY CHANGE:

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

Note:

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