NOTE:
When first operating the Weather Station, it is important to
completely set-up the wiring and 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.
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.
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.
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 thermohygro 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.
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.
You should check the cable for correct connection and test all the components for
correct functionality by manually turning the wind-gauge and by moving the windvane; tilting the optional rain sensor to hear the impact of the internal moving seesaw,
etc. (See Positioning below).
Time and date must be manually set (See Manual Setting below).
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.
7
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 THERMOHYGRO 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 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:
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.

Insert 2 x AAA IEC LR3 1.5V batteries into the battery compartment, observing the
correct polarity.
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:
Sunny
Cloudy with sunny intervals
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.
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
19
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
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.
20
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.
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.
21
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

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.
To view the weather history:
1.
In normal display, press the HISTORY key. The latest weather record will be shown
with the date and time of recording. The "HISTORY" icon will be displayed at the
bottom of the LCD.

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 be synchronized 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 be
decreased. 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 setting 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.
2.
3.
4.
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.
Avoid positioning the Weather Center onto or in the immediate proximity of metal
doors or window frames.
Using other electrical products such as headphones or speakers operating on the
same signal frequency (915 MHz) may prevent correct signal transmission and
reception.
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).
30
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 attached. Please visit your local retailer or
www.lacrossetechnology.com and click on the Buy button to 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 hang on a wall or free standing with the foldout stand.
To wall mount
Choose a sheltered place. Before wall mounting, please check that
the outdoor temperature and humidity values can be received from
the desired locations. To wall mount:
1.
2.
Fix a screw (not supplied) into the desired wall, leaving the
head extended out the by about 5mm.
Hang the station onto the screw. Remember to ensure that it
locks into place before releasing.
31
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
32
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 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 the mounting bracket.
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.
33
CARE AND MAINTENANCE:
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.
