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 components for correct function  
before placing and mounting them at their final 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.

HYSTERESIS  
HIGH AND LOW OUTDOOR HUMIDITY ALARM SETTING  
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 the temperature drops to +76.8°F or below and  
Note:  
The High and Low outdoor humidity alarm can be set On/Off independently  
according to your needs.

86  
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) so that the alarm can be produced again. Hysteresis  
values for the various weather data types are given in the following table:  
about 75% due to the varying areas the Weather Center 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 stagnant most of the time  
(for example mostly sunny).  
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.

The temperature or humidity data will keep on flashing even after a key has

WEATHER TENDENCY INDICATOR  
Working together with the weather icons is the weather tendency 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.  
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:  
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.  
TENDENCY

Cloudy with sunny  
intervals  
Sunny  
Note:  
Once the weather tendency indicator has registered a change in air  
pressure, it will remain permanently visualized on the LCD.  
For every sudden or significant change in the air pressure, the weather  
icons will update accordingly to represent the change in weather.  
AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH  
BAROMETRIC PRESSURE TREND)  
(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 these values is bigger than the selected weather  
tendency sensitivity, the weather-icon changes, either for worse or for  
better. In this case, the current pressure value becomes the new weather  
tendency reference.)  
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 bars.  
The bar graph of the electronic barometer shows the air pressure history of  
the past 12 hours in five 3-hour steps.  
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 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.  
Air pressure  
changes in inHg  
Air pressure  
changes in hPa  
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.  
Note:  
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  
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  
88  
89  
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.  
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 in  
Beaufort scale, 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:  
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.  
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,

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.  
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  
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.  
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.  
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 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 transmitter and the rain sensor.  
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.  
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:  
The Weather Center  
The Weather Center has been designed to be hung onto wall or free  
standing.  
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.  
The distance of the Weather 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.  
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.  
2.  
3.  
1.  
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.  
2.  
4.  
5.  
“Visibility” of weather center and transmitters (e.g. through a window)  
increases the range. (Delete, b/c Windows often reflect the signal)  
The Thermo-hygro Sensor  
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.  
Rain Cover  
During normal operation, after the outdoor display 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).  
Main nit  
If no reception is possible despite the observation of these factors, all  
system units have to be reset (see Setting up).  
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.  
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  
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 correctly plugged in otherwise data transmission errors  
could occur.

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.  
The Wind Sensor  
Wind  
vane  
Vertical  
mast  
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.  
Wind fan  
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.  
Horizontal  
panel  
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 circuit of the device as there is a  
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.  
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 socket so that 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.
