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.

Transmitter signal reception icon

• 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:

In case the wind speed exceeds the condition for high wind speed alarm, the value will be flashing, along with the corresponding high alarm icon ("HI AL"). And the buzzer will ring for 2 minutes. User may press any key to stop the sound.

HYSTERESIS

To compensate for fluctuation of the measured data, which may cause the weather alarm to sound constantly if the measured reading is close to your set level, a hysteresis function has been implemented for each weather alarm. For example, if the high temperature alarm is set to +77°F and the current value moves to +77°F, the alarm will be activated (if it has been enabled). Now when t he temperature drops to +7 6.8°F or below and

thereafter again increases to beyond +77°F, the data will be blinking, but no alarm will be activated. It has to drop to below +75.2°F (with a pre-set hysteresis of 1.8°F) s o that the alarm can be produced again. Hysteresis values for the various weather data types are given in the following table:

Weather data Hysteresis

Temperature 1.8°F Humidity 3% RH Wind speed 3.1 mph

Note:

The temperature or humidity data will keep on flashing even after a key has been pressed to stop the alarm or buzzer has been switched off, to indicate that the current weather condition is out of the pre-set limit(s)

WEATHER FORECAST AND WEATHER TENDENCY WEATHER FORECASTING ICONS:

Weather forecasting icons are displayed in any of the following combinations at the right bottom part of LCD:

TENDENCY

Sunny

For every sudden or significant change in the air pressure, the weather icons will update accordingly to represent the change in weather.

(Every time a new average pressure value has been obtained (once per minute), this value is compared with an internal reference value. If the difference between t hese values is bigger than the selected weather tendency sensitivity, the weather-icon changes, either for w orse o r for better. In this case, the current pressure value becomes the new weather tendency reference.)

If the icons do not change, either the air pressure has not changed or the change has been too small for the Weather Center to register. So you may adjust the "sensitivity" of the pressure change checking in the setting mode –see WEATHER TENDENCY SENSITIVITY VALUE SETTING above. However, if the icon displayed is a sun or raining cloud, there will be no change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons are already at their extremes. The icons displayed forecasts the weather in terms of getting better or worse and not necessarily sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does not mean that the product is faulty becau se it is not raining. It simply means that the air pressure has dropped and the weather is expected to get worse but not necessarily rainy.

Note:

After setting up, readings for weather forecasts should be disregarded for the next 48-60 hours. This will allow sufficient time for the Weather station to collect air pressure data at a constant altitude and therefore result in a more accurate forecast.

Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasti ng feature is estimated to have an accuracy level of

TENDENCY

Cloudy with sunny

intervals

TENDENCY

Rainy

about 75% due to the varying areas the Weather Cent er has been designed for use. In areas that experience sudden changes in weather (for example from sunny to rain), the Weather Center will be more accurate compared to use in areas where the weather is sta gnant most of the time (for example mostly sunn y). If the Weather Center is moved to another location significantly higher or lower than its initial standing point (for example from the ground floor to the upper floors of a house), discard the weather forecast for the next 48-60 hours, as the Weather Center may mistake the new location as being a possible change in air-pressure when really it is due to the slight change of altitude.

WEATHER TENDENCY INDICATOR

Working together with the weather icons is the weather tendenc y indicators (arrow located on the left and right sides of the weather icons). When the indicator points upwards, it means that the air-pressure is increasing and the weather is expected to improve, but when indicator points downwards, the air-pressure is dropping and the weather is expected to become worse.

Taking this into account, one can see how the weather has changed and is expected to change. For example, if the indicator is pointing downwards together with cloud and sun icons, then the last noticeable change in the weather was when it was sunny (the sun icon only). Therefore, the next change in the weather will be cloud with rain icons since the indicator is pointing downwards.

Note:

Once the weather tendency indicator has registered a change in air pressure, it will remain permanently visualized on the LCD.

AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH BAROMETRIC PRESSURE TREND)

The bottom section of the LCD also shows the relative air pressure value and the air pressure history. Depending on programming conditions, display of the history of air pressure in form of a gr aph consisting of vertical bars. The bar graph of the electronic barometer shows the air pressure history of the past 12 hours in f ive 3-hour steps.

Air pressure

changes in inHg

The horizontal axis represents the last 12 hours air pressure recording (-12,

-9, -6, -3 and 0 hour). The bars are plotted at each of the 5 steps and give

the trend over the recorded period. The scale on the right compares the result. The "0" in the middle of this scale determines the current air pressure.

The vertical axis represents the air pressure changes in inHg (+0.12, +0.06, 0, -0.06, -0.12. The “0” represents the current air pressure). The newly measured pressure was compared to the previously recorded pressure reading. The pressure change is expressed by the difference between the current ("0h") and th e past readings in division of ±2 hPa or ±0.06 inHg. If the bars are rising it indicates that the weather is getting better due to an increase in air pressure. If the bars go down it indicates a drop of the air

pressure and the weather is expected to get wors e from the present time "0". At every full hour, the current air pressure is used as a basis for the display of a new graph bar. The existing graph is then moved one column to the left.

Note:

For accurate barometric pressure trend, the Weather Center should operate at the same altitude. For example, it should not be moved. Should the unit be moved, for instance from the ground to the second floor of the house, the readings for the next 48-60 hours shall be discarded.

battery power is low. It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of the system.

Note:

• After battery change, both the Weather Station and the transmitters

need to be reset (see note ”Setting up”)

• The History data record will be clear after the battery change.

OUTDOOR TRANSMITTER 915 MHz RECEPTION CHECK

The outdoor temperature, humidity, wind data are transmitted from thermohygro transmitter every 4.5 seconds; the rainfall data are transmitted from the rain sensor every 6.25 seconds. The receiver will be synchronized to the thermo-hygro transmitter and rain sensor then. The transmission range (supposedly up to about 330 feet /100 meters) of the thermo-hygro transmitter/ rain sensor may be affected by the ambient temperature. At cold temperatures, the transmitting distance may be decreased. Please keep this in mind when placing the transmi tter and the rain sensor.

If (1) the outdoor data are not being received within first several minutes after setting up; (2) the outdoor display always show “- - -“ on the outdoor display; or (3) the reception icon of thermo-hygro transmitter (Mode 1) and rain sensor (Mode 2) is not displayed on the display, user shall check the following points:

1. The distance of the Weat her Center or transmitter/ rain sensor should be at least 5 to 6.5 feet (1.5 to 2 meters) away from any interfering sources such as computer monitors or TV sets.

2. Avoid positioning the Weather Center onto or in the immediate proximity of metal doors or window frames.

3. Using other electrical products such as headphones or speakers operating on the same signal frequency (915 MHz) may prevent correct signal transmission and reception.

4. Neighbors using electrical devices operating on the 915 MHz signal frequency can also cause interference.

5. “Visibility” of weather center and transmitters (e.g. through a window) increases the range. (Delete, b/c Windows oft en reflect the signal)

Note:

When the 915 MHz signal is received, do not re-open the battery compartment cover of either the transmitter/ rain sensor or Weather Center, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur. During normal operation, after the outdoor dis play shows "- - -", the weather center will change to receive the outdoor data every 15 minutes, until the data is read. Then the reception period for thermo-hygro transmitter will return to 4.5 seconds (6.25 seconds for rain sensor).

If no reception is possible despite the observation of these factors, all system units have to be reset (see Se tting up).

POSITIONING:

Prior to permanently affixing any of the units, please ensure the following points are considered:

• Cable lengths of the units meet with your dist ance requirements at

the point of fixing

• Signals from the sensors can be received by th e base station at

points of mounting

La Crosse Technology Sensor Extension Cable

When you require additional length to properly mount your sensor, you can use La Crosse Technology extension cable. The extension cable is 32 feet in length and comes with the appropriate connecter attached. Please visit your local retailer or www.greatbigoutlet.com

Phone cables and connections have much more resistance than our extension cable and are not recommended for use. Using phone cable/connection may damage your sensors.

Note: Using extension cables will shorten battery life. Warning: Never cut, splice, shorten or modify your sensor cables or

extension cables. Doing so may damage your sensors and will void your warranty.

The Weather Center

The Weather Center has been designed to be hung onto wall or free standing.

The Thermo-hygro Sensor

An ideal mounting pla ce for the thermo-hygro sensor would be the outer wall beneath the extension of a roof, as this will protect the sensor from direct sunlight and other extreme weather conditions.

To wall mount, use the 2 screws to affix the wall bracket to the desired wall, plug in the thermo-hygro sensor to the bracket and secure both parts by the use of the supplied screw and ensure that the cables from the wind and rain sensors are correc tly plugged in otherwise data transmission errors could occur.

To wall mount

Choose a sheltered place. Avoid direct rain and sunshine. Before wall mounting, please check that the outdoor values can be received from the desired locations. To wall mount:

1. Fix a screw (not supplied) into the desired wall, leaving the head extended out the by about 5mm.

2. Hang the station onto the screw. Remember to ensure that it locks into place before releasing.

Wall Bracket

The Wind Sensor

Firstly, check that the wind-cups and the wind-vane can rotate freely before fixing the unit. For correct and accurate readings, it is important to mount the sensor so that the front (marked E) is pointing in East-West direction. The wind sensor should now be mounted using the screw or cable tie provided onto a solid wall/ panel mast or mast to allow the wind to travel around the sensor unhindered from all directions (ideal mast size should be from diameter 0.62” to 1.29” (16mm to 33mm). Do not over tighten. Once the wind sensor is fixed onto the mast, connect the cable to the corresponding thermo-hygro sensor soc ket so tha t operating power supply can be received and data can be transmitted to the base station. Secure cord from blowing. Do not us staples. Using PVC pipe or metal as a mast may cause static. Wood is recommended.

The Rain Sensor

For best results, the rain sensor should be securely mounted onto a horizontal surface about 39.37” (1 meter) above the ground (or higher) and in an open area away from trees or other coverings where rainfall may be reduced causing inaccurate readings.

When securing into place, check that rain excess will not collect and store at the base of the unit but can flow out between the base and the mounting surface (test by pouring clean water).

After mounting the rain sensor and placing battery, the rain sensor is now operable. For testing purposes, very slowly pour a small amount of clean water into the rain sensor funnel. The water will act as rainfall and will be received and displayed at the base station after about 2 minutes delay i.e. when the reading interval is re ac hed.
