IMPORTANT:  
- Do Not Mix Old and New Batteries  
- Do Not Mix Alkaline, Standard, or Rechargeable Batteries  
NOTE:  
When first operating the Weather Station, it is important to completely set-up the wiring and the rest of the  
system in close proximity (e.g. on a table 5ft-10ft from display) and test all components for correct  
function before 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. Be sure the  
cord “clicks” into place.  
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. 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 will be displayed on the Weather Center. If this does not happen  
after 135 seconds, remove the batteries 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. (optional rain gauge).

6. Check the cable for correct connection and test all the components for correct functionality by  
manually turning the wind-gauge; 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 and found fit, the initial set up of the weather station  
system is finished and the mounting of the system components can take place. Ensure that all  
components work properly together at their chosen mounting or standing locations before permanent  
mounting.  
For example, if there appears to be problems with the 915 MHz radio transmissions, they can often  
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 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).  
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 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 THERMO-HYGRO 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. Remove the airflow 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 airflow 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 the thermo-hygro sensor at start-up assigns a random security code 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 2 x C, IEC LR14 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.  
2.  
Remove the battery compartment cover.  
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 the transmitter and rain sensor (optional) assign a random security code at  
start-up and these codes 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.

WEATHER FORECAST AND WEATHER TENDENCY  
WEATHER FORECASTING ICONS  
Weather icons in the third section of LCD can be displayed in any of the following combinations:  
Cloudy with sunny intervals  
Sunny  
Rainy  
For every sudden or significant change in the air 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  
changed or the change has been too slow for the Weather station to register. 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.  
 
10  
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 because 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 set 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 forecasting  
feature is estimated to have an accuracy level of about 75% due to the varying 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 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. 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 change of altitude.  
WEATHER TENDENCY INDICATOR  
Working together with the weather icons is the weather tendency indicators (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.  
The bar graph of the electronic barometer shows the air pressure history of the past 12 hours in five 3-  
hour steps.  
Air pressure  
changes in hPa  
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 the 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 worse 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.  
 
11  
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..  
WIND SPEED MEASUREMENT  
In normal display mode, the second section of the LCD shows the following wind data.  
Wind chill in F or C  
Wind Speed in km/h, mph or m/s  
Gust in km/h, mph or m/s (displayed when in Mode 2, by pressing the SET key shortly)

VIEW THE HISTORY DATA  
The weather station can store up to 140 sets of weather data which are recorded automatically at 3-hour  
intervals after the weather station is powered up, at the nearest time of 0:00, 03:00, 06:00, 09:00, 12:00,  
15:00, 18:00 and 21:00. For instance, if user has manually set the time as 14:52 after installing batteries,  
the first history record will be made at the coming 15:00 automatically. Then the second record will be on  
18:00 and so on.  
Each weather record includes the Wind direction, Wind speed/ gust, Wind chill temperature, wind  
speed/gust, dew point, Outdoor temp and humidity, relative pressure, 24-hour rainfall and total rainfall,  
pressure history and weather tendency. Also, the time and date of recording will be displayed.  
NOTE:  
In order to acquire the correct time of recording of the history records, you shall manually set the current  
time as soon as installing batteries to the weather station. Afterwards, you should avoid changing the pre-  
set time as it will also alter the recorded "time of recording" of each history record, which may lead to  
confusion.

Press the + key once when the Rainfall value and Reset icon are shown.  
Then the total rainfall amount will be reset to 0, and the time updated to current time.  
NOTE:  
After power up, the time and date and total rainfall are displayed as "- - -". After time is adjusted manually,  
the set time will be shown.  
LOW BATTERY INDICATOR  
The low battery indicator of the weather station and the transmitter will be displayed in the second section,  
and the low battery icon for the rain sensor (optional) will be shown on the last section of the LCD  
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 ”Set  
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 thermo-hygro transmitter every 4.5  
seconds; the rainfall data are transmitted from the rain sensor (optional) every 6.25 seconds. The receiver  
will synchronize to the thermo-hygro transmitter and rain sensor (optional) then. The transmission range  
(up to about 330 feet /100 meters in open air) of the thermo-hygro transmitter/ rain sensor may be  
affected by the ambient temperature. At cold temperatures, the transmitting distance may decrease.  
Please keep this in mind when placing the transmitter and the rain sensor.  
If (1) the outdoor data is not being received within first several minutes after set up; (2) the outdoor  
display always shows “- - -“ on the outdoor display; or (3) the reception icon of thermo-hygro transmitter  
(Mode 1) and rain sensor (optional) (Mode 2) is not displayed on the display, check the following things:  
1. The distance of the Weather Station 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.  
NOTE:  
When the 915 MHz signal is received, do not re-open the battery compartment cover of the transmitter/  
rain sensor or Weather station, as the batteries may spring free from the contacts and force a false reset.  
Should this happen accidentally then reset all units (see Set 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 despite the observation of these factors, all system units have to be reset (see  
Set up).  
POSITIONING:  
Prior to permanently mounting 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 sensor. The extension cable is 32 feet in length and comes with the appropriate connecter  
 
16  
locate an online dealer or other retailers.  
Using phone cables or connections may damage your sensors because phone cables and connections  
have more resistance than the La Crosse Technology 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 Weather Station  
The Weather Station is designed to be free standing only.  
The Thermo-hygro Sensor  
Rain Cover  
Main Unit  
Wall Bracket  
An ideal mounting place 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. Be sure to  
mount vertically.  
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 cable  
from the wind sensor is correctly plugged in otherwise data transmission errors could occur.  
The Wind Sensor  
Vertical mast  
Wind -cups  
Horizontal panel  
Check that the wind-cups can rotate freely before fixing the unit. For correct and accurate readings, it is  
important to mount the sensor with the cups on the bottom. The wind sensor should now be mounted  
using the screw or cable tie provided onto a solid wall/ panel mast or mast to allows 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 the mounting bracket  
.
 
17  
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 received and data can be transmitted to the base station.  
Secure cord from blowing. Do not use staples. Using PVC pipe or metal as a mast may cause static.  
Wood is recommended.  
The Rain Sensor (optional)  
Horizontal panel  
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). Do not tighten screws  
past just snug.  
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 i.e. when the reading interval is reached.  
CARE AND MAINTENANCE:  
Do Not Mix Old and New Batteries  
Do Not Mix Alkaline, Standard, or Rechargeable Batteries  
Extreme temperatures, vibration and shock should be avoided as these may cause damage to the  
unit and give inaccurate forecasts and readings.  
Precautions shall be taken when handling the batteries. Injuries, burns, or property damage may be  
resulted if the batteries are in contact with conducting materials, heat, corrosive materials or  
explosives. The batteries shall be taken out from the unit before the product is to be stored for a long  
period of time.  
Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new  
batteries of the recommended type.  
When cleaning the display and casings, use a soft damp cloth only. Do not use solvents or scouring  
agents as they may mark the LCD and casings.  
Do not submerge the unit in water.  
Special care shall be taken when handling a damaged LCD display. The liquid crystals can be  
harmful to user's health.  
Do not make any repair attempts to the unit. Return them to their original point of purchase for repair  
by a qualified engineer. Opening and tampering with the unit may invalidate their guarantee.  
Never touch the exposed electronic circuitry of the device, as there is danger of electric shock, should  
it become exposed.  
Do not expose the units to extreme and sudden temperature changes, this may lead to rapid changes  
in forecasts and readings and thereby reduce their accuracy.
