Note:

When putting the Weather St atio n into operation, it is important to perform in close prox im it y (e.g. on a tab le) a complete 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 final destinations (See Positioning below):

1. Unwind the cables of the Wind sensor. Connect the

2. First insert the batteries into the The r m o-hygro sensor and Rain sensor (purch as e separately) “How t o install and replace the batteries into the Thermo-hygro

sensor“ and “How to install and repla ce the batteries into the Rain sensor (optional)” below).

3. Then insert the batteries into the Weather C enter (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 bri ef ly . It will the n di spla y the time as 12:00, the date as 1.1.09, the weather icons, and air pr e ss ur e value. " - - -" will be shown for outdoor data.

4. Afterwards, the Weather Center will start receiving data from the transmitter. The transmission recepti on i co n will be b lin k in g to ind ic at e that t he stat i on i s trying to get the thermo-hygro tr ansmitter data. The outdoor temperature, humidity, wind data should then be displayed on the Weather Center. If this does not ha pp en aft e r 135 seconds, the batterie s will need to be removed from all units. You will have to start again from step 2.

5. The transmitter reception ic on is n ow blink in g ag ain t o in d ic at e th at th e stat i on i s 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 th e cable for correct connection and all the components for correct function by man ually turning the wind-gauge by moving the wind-vane; tilting the rain sensor to hear the impact of the interna l moving seesaw, etc. (se e Positioning below).

7. Time and date shall be manually set (See Manual Setting below).

8. After the Weather Center has been check ed for co rr e ct fun ctio n w ith re g ard to the above points and fou nd 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. If e.g. t her e a ppear 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 i n the open field reaches distances of max 330 feet/ 100 met er s, pr ov ided t h er e are n o inte rfe rin g ob st acl es 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 t r an s mitt er s as s oo n as poss ible. I f t he w eat her 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, 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 the signal is successfully received by the Weather Center, the switched on. (If it is not successful, the can easily see whether the last reception was successful ( 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 45

seconds, the frequency is changed to 920MHz and the learning is tried another 45 seconds. If still not suc c essful, the reception is tried for 45 seconds on 9 10MHz. This will also be done for re-synchronization.

HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE THERMOHYGRO TRANSMITTER

Note:

In the event of changing batteri es 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 fi rst several minutes of power being supplied to it.

HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE WEATHER STATION

The outdoor Thermo-hygro tran smit t er works with 2 x AA IEC LR6,

1.5V batteries. To install and re p la ce th e bat t er i es, pl ea s e follow the steps below:

1. Uninstall the rain cover of the transmitter.

2. Remove the battery compartment cove r.

3. Insert the batteries, observing the correct polarity (see the marking in the battery compartm ent ).

4. Replace the battery cover and the rain cover onto the unit.

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 batter i es, ple a se f ol low the steps below:

1. Remove the battery compartment cover.

WEATHER FORECAST AND WEATHER TENDENCY WEATHER FORECASTING ICONS

Weather icons in the third section of L CD can b e displayed in any of the following combinations:

Flashing

For every sudden or significant change in the a ir pressure, the weather icons will update accordingly to represent the change in weather. If the icons do not change, then it means either the air pressure has not change d or the ch an ge ha s bee n too slow for the Weather station to register. However, if the ico n di sp layed is a sun or raining cloud, there will be no change of icon if the weather gets any better (w ith sunny icon) or worse (with rainy icon) since the icons are already at t heir ext re me s.

The icons displayed forecasts the weather in terms of getting better or w orse and n ot 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 because it is not raining. It simply means that the air pr ess ur e has dr opp e d and t he w eather is expected to get worse but not neces sar i ly rainy .

Note: After setting up, readings for weat her f ore c asts sh ou ld be di sr eg ar d ed for th e next 48- 60 hours. This will allow sufficient time for the Weather station to collect air pressure data at a constant altitude and theref or e r esult in a more accurate forecast.

Common to weather forecasting, absolute accur acy cannot be guaranteed. The weather forecasting feature is estimated to have an accuracy level of about 75% due to the vary ing areas the Weather station has been designed for use. In areas that experience sudden changes in weather (for example from sunny to rain), the Weather station will be more accurate compared to use in areas where the weather is stagnant most of the time (for example mostly sunny).

If the Weather station is moved to another locat ion 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 n ext 48- 6 0 ho urs. By doing this, the Weather Station will not mistake the new location as being a possible change in air-pressure when really it is due to the slight c hange of altitude.

WEATHER TENDENCY INDICATOR

Working together with the weather icons is the weather tendency indicators (located on the left and right sides of t he weather icons). When th e indicator points upwards, it means that

Sunny

Cloudy with sunny intervals

Rainy

the air-pressure is increa si ng a nd the weather is expected to improve, but w hen in di c at or points downwards, the air-pressure is dropping and the weather is ex pected to become worse.

Taking this into account, one ca n see h ow the weather has changed and is expected t o change. For example, if the indicator is pointing downwards together with cloud and sun icons, then the last noticeab l e chan ge i n th e weather was when it was sunny (the sun icon only). Therefore, the next change in the weather will be cloud with ra in icons since the indicator is pointing downw ards.

Note: Once the weather tendency indic at or has r egi st ere d a cha ng e in air pre ssu r e, it w ill re mai n 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 graph consisting of vertical bar s. The bar graph of the electronic bar om et er shows the air pressure history of the past 12 hours in five 3-hour steps.

The horizontal axis represent s th e la st 12 ho urs a ir pr ess ur e rec or ding (- 12, -9, - 6, -3 and 0 hour). The bars are plotted at eac h of the 5 st eps and gi v e the t r en d over the re cor d ed period. The scale on the right compares the result. The "0" in the middle of this scale determines the current air pr ess ure.

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 pre s sur e). T he n ewly measured pressure was compar ed to the previously recorded pr es sure reading. The pressure chang e is expr e ss e d by the difference between the curr ent (" 0 h") and t he past rea din gs in di vi s ion of ±2 h Pa or ±0. 0 6 inHg. If the bars are rising it indicates t h at th e weather is getting better due to an increas e in air pressure. If the bars go down it ind ic at es a drop of the a ir pr es s ur e and t he w eather

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 move d one co lu mn to th e left .

Note:

For accurate barometric pressure trend, the Weather Cent er s hou ld o per at e at the same altitude. For example, it shoul d not b e mo v ed.

LOW BATTERY INDICATOR

The low battery indicator of the weather station and the transmitter will be displayed at the second section, and the low battery icon for the rain sensor (optional) will be display on the last section of the LC D respectively when the 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 RECEPTI ON CHECK

The outdoor temperature, h umi dity, wind data are transmitted fr om ther m o- hy gr o transmitter every 4.5 secon ds; th e rai nf al l dat a are t ran s mit t ed fr om t he ra in se ns or (optional) every 6. 25 seconds. The receiver will be synchronized to the thermo-hygro transmitter and rain sensor (optional) then. The transmission range (supposedly up to about 330 feet /100 meters) of the therm o- hy gro tr a nsmit t er/ ra in sens or m ay be aff ect e d by the ambient temp er ature. At cold temperatures, the transmitting distance may be decreased. Please keep this in mind when placing the transmitter and the rain sensor.

If (1) the outdoor data are not being recei ve d w ithi n fir st sev er al m in ut es aft er sett i ng up; (2) the outdoor display always show “- - -“ on the outdoor display; or (3) the reception icon of thermo-hygro transmit ter ( Mo de 1) a nd r ai n se nso r (o ptio na l ) (Mo de 2) is not dis p layed on the display, user shall check the following points:

1. The distance of the Weather Station or tra ns mitt e r/ rai n se n sor shou ld b e at le a st 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 t he Weather Center onto or in the immediate proximity of metal doors or window frames.

3. Using other electrical produ cts s uc h as headp h on es or sp ea k ers op erating on the same signal frequency (915 MHz) may prevent correct signal transmission and reception.

4. Neighbors using electrical de vi c es oper at i ng o n the 91 5 MHz si gnal fr eq ue n cy can also cause interference.

5. “Visibility” of weather center and transmitters increases the range

Note:

When the 915 MHz signal is received, do not re-open the battery compartment cover of either the transmitter/ rain sensor or Weather station, as the batteries may spring free from the contacts and force a false reset. Shou ld t his ha pp e n acci d ent a lly then reset all units (see Setting up above) otherwise transmission problems may occur. During normal operation, after the outdoor display shows "- - -", the weather station 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 - optional).

If no reception is possible despit e the o bs er vation of these factors, all system un it s have t o be reset (see Setting 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 distance requirements at the point of fixing  Signals from the sensors can be received by the base station at points of mounting

La Crosse Technology Sensor Extension Cable

You can purchase a La Crosse Technology Extension Cable if you require additional length to properly mount your s en sor. The extension cable is 32 feet in lengt h and co m es with the appropriate connecter attached. Please visit your local retailer or www.lacrossetechnology.com other retailers.

Using phone cables or connections may damage your sensors because phone cables and connections have more res ist a n ce tha n t h e La Cro sse T ec h no logy phone extension cable. Phone cables or connections are not recommended for use.

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 Thermo-hygro Sensor

An ideal mounting place for the th er mo- hygro sensor would be the outer wall b ene at h the extension of a roof, as this will protect the sensor from direct sunlig ht 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 bra cket a n d secure b ot h part s by the use of the sup pl ied scr ew and ensure that the cables from the wind and rain sensors are correct ly plugged in otherwise data transmission errors could occur.

Choose a sheltered place. Avoi d dir ect rain an d s un s hi ne. Before wall mounting, pleas e check t hat the o ut do or te mper ature and humidity values can be receiv ed 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 5m m.

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

The Wind Sensor

Firstly, check that the wind-cups 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 socket so that operating power supply can be re ceived and data can be transmitted to the base station. Secure cor d from blowing. Do not use staples. Using PVC pipe or metal as a mast may cause static. Wood is recommended.
