Note:  
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  
6
 
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 rain and the wind sensors. Connect the rain and the  
wind sensors to the thermo-hygro sensor by plugging the connector heads of  
the two sensors into the appropriate sockets of the thermo-hygro sensor.  
Sockets for wind  
and rain sensor  
2.  
3.  
First insert the batteries into the thermo-hygro sensor (see “How to install and  
replace the batteries into the thermo-hygro sensor“ 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 and a short signal  
tone will be heard. It will then display the time as 12:00, the date as 1.1.05, the  
weather icons, and air pressure value. "- - -" will be shown for outdoor data.  
Afterwards, the Weather Center will start receiving data from the sensor. The  
outdoor temperature, humidity wind chill and wind speed should then be  
4.  
7
 
displayed on the Weather Center. If this does not happen after 30 seconds, the  
batteries will need to be removed from both units. You will have to start again  
from step 1.  
5.  
You may then check all cables for correct connection and all components for  
correct function by manually turning the wind-gauge, moving the weather-vane,  
tilting the rain sensor to hear the impact of the internally moving seesaw, etc  
(See Positioning below).  
6.  
7.  
Time and date shall be manually set (See Manual Setting below).  
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 Center system  
is finished and the mounting of the system components can take place. It must  
be verified, however, 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.  
Note:  
The radio communication between the receiver and the sensor 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.  
8.  
Radio interferences created by PC screens, radios or TV sets can in some  
cases entirely cut off radio communication. Please take this into consideration  
when choosing standing or mounting locations.  
Note:  
The thermo-hygro sensor should be placed in a dry, shaded area. The temperature  
sensor has a range of 330 feet. Keep in mind that the 330 feet is in open air with no  
8
 
obstructions and that radio waves DO NOT curve around objects. Actual transmission  
range will vary depending on what is in the path of the signal. Each obstruction (roof,  
walls, floors, ceilings, thick trees, etc.) will effectively cut signal range in half.  
Example: A Professional Weather Center with a 330 feet range is mounted on an  
interior wall, so that the signal has to pass through one interior wall, one exterior wall,  
and across the 10 feet width of the room between the 2 walls. The first wall will  
reduce the range to 165 feet, and the second wall will reduce the range to 87 feet.  
Factoring in the 10 foot room, this leaves a maximum of 77 feet of remaining signal  
range.  
This allowance is typically enough for a frame wall with non-metallic siding; however  
certain materials can reduce range even further. Metal siding, stucco, and some  
types of glass can reduce signal range by as much as ¾ or more, compared to the ½  
reduction typical of most obstructions. It is possible to receive a signal through these  
materials, however maximum range will be much less due to their tendency to absorb  
or reflect a much larger portion of the sensor’s signal  
.
Note :  
After batteries are installed in the sensor, install the batteries in the Weather  
Center to receive the signal from the sensor as soon as possible. If the  
Weather Center is powered more than 5 hours after the sensor is powered, the  
Weather Center will never receive signal successfully from this sensor. In this  
case, user will need to reinstall the batteries from the sensor to redo set-up  
procedure.  
9
 
After batteries are installed, there will be synchronization between Weather  
Center and the sensor. 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.  
Sensor signal reception  
icon  
If the signal reception is not successful on the first frequency (915MHz) for 14  
seconds, the frequency is changed to 920MHz and the learning is tried another  
14 seconds. If still not successful the reception is tried for 14 seconds on  
910MHz. This will also be done for re-synchronization.  
HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE WEATHER  
CENTER  
The Weather Center 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:  
10  
 
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.  
HOW TO INSTALL AND REPLACE THE  
BATTERIES INTO THE THERMO-HYGRO SENSOR  
The outdoor thermo-hygro sensor works with 2 x “AA”,  
IEC LR6 1.5V batteries. To install and replace the  
batteries, please follow the steps below:  
1.  
2.  
3.  
Uninstall the rain cover of the sensor.  
Remover the battery compartment cover.  
Insert the batteries, observing the correct polarity (see  
the marking in the battery compartment).  
Replace the battery cover and the rain cover onto the  
unit.  
4.  
11  
 
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 30 seconds of power being supplied to it.  
BATTERY CHANGE:  
It is recommended to replace the batteries in all units every 24 months to ensure  
optimum accuracy of these units.  
Please participate in the preservation of the environment. Return  
used batteries to an authorized depot.  
Note:  
The stored History record will not be kept after the battery change is done on the  
Weather Center.

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 the temperature drops to  
+76.8°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) so that the alarm can be produced again. Hysteresis values for  
the various weather data types are given in the following table:  
Weather data  
Temperature  
Humidity  
Hysteresis  
1.8°F  
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 is displayed in any of the following combinations at the right  
bottom part of LCD:  
TENDENCY  
TENDENCY  
TENDENCY  
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.  
(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.)  
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.  
Note:  
After setting up, readings for weather forecasts should be disregarded for the next 12-  
24 hours. This will allow sufficient time for the Weather Center 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 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.  
34  
 
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.  
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 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.  
35  
 
Air pressure  
Air pressure  
changes in inHg  
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.  
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  
36  
 
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  
12-24 hours shall be discarded.  
WIND DIRECTION AND WIND SPEED MEASUREMENT  
In normal display mode, the second section of the LCD shows the following wind data.

RAINFALL MEASUREMENT  
The total rainfall measurement is displayed in the fourth section of the LCD, in the unit  
of mm or inch. (see VIEWING THE MIN/MAX WEATHER DATA below)  
VIEWING THE HISTORY DATA  
The Weather Center can store up to 200 sets of weather data which are recorded  
automatically at 3-hour intervals after the weather center 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 in Beaufort scale, Wind  
chill temperature, wind speed, outdoor temperature and humidity, relative pressure  
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 Center.  
38  
 
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.  
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.

2.  
Press ALARM key once to return to the normal display mode. The "BUZZER  
OFF" icon will no longer be shown. Then the alarm will sound normally.  
LOW BATTERY INDICATOR  
The low battery indicator of the Weather Center and the Thermo-hygro sensor will be  
displayed at the top and bottom portion 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 Center and the thermo-hygro sensor  
need to be reset (see note ”Setting up”)  
The history data record will be clear after the battery change.  
48  
 
OUTDOOR SENSOR 915 MHz RECEPTION  
The outdoor temperature, humidity, wind data and rainfall are transmitted from the  
thermo-hygro sensor about every 4.5 seconds. The Weather Center will then be  
synchronized to the thermo-hygro sensor to receive outdoor data. The transmission  
range (up to 330 feet) of the thermo-hygro 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 sensor.  
If the outdoor data are not being received within 60 seconds after setting up (or the  
outdoor display shows “- - -“ in the outdoor section of the Weather Center after  
consecutive failed attempts during normal operation). Please check the following  
points:  
1.  
2.  
3.  
The distance of the Weather Center or sensor should be at least 5 to 6.5 feet  
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, speakers, or cordless  
phones operating on the same signal frequency (915 MHz) may prevent  
correct signal transmission and reception.  
4.  
5.  
Neighbors using electrical devices operating on the 915 MHz signal frequency  
can also cause interference.  
“Visibility” of Weather Center and thermo-hygro sensor (e.g. through a window)  
increases the range.  
Note:  
When the 915 MHz signal is received, do not re-open the battery compartment  
cover of either the sensor or Weather Center, as the batteries may spring free  
from the contacts and force a false reset. Should this happen accidentally then  
49  
 
reset all units (see Setting up above) otherwise transmission problems may  
occur.  
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 again. Then the reception period will return to 4.5 seconds.  
The transmission frequency may be switching between 910, 915 and 920 MHz  
to enable successful signal reception by the Weather Center.  
If no reception is possible despite the observation of these factors, all system  
units have to 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 center at points of  
mounting  
Weather Center  
The Weather Center has been designed to be hung onto wall or free standing with the  
2 kinds of foldout stand.  
To wall mount  
Before wall mounting, please check that the outdoor temperature and humidity values  
can be received from the desired locations. To wall mount:  
50  
 
1.  
2.  
Fix a screw (not supplied) into the desired wall, leaving the  
head extended out the by about 5mm.  
Hang the Weather Center onto the screw. Remember to  
ensure that it locks into place before releasing.  
Thermo-hygro Sensor  
Rain Cover  
Main Unit  
Wall Bracket  
51  
 
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.  
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.  
Wind Sensor  
Wind vane  
Vertical  
mast  
Wind fan  
Horizontal  
panel  
52  
 
Firstly, check that the wind-fan 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 about 5/8” to 11/4”).  
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 center.  
Rain Sensor  
For best results, the rain sensor should be securely mounted onto a horizontal surface  
about 1 meter above the ground 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).  
53  
 
After mounting the rain sensor, connect the cable to the thermo-hygro sensor at the  
corresponding socket so power supply can be received and data be transmitted to the  
base center  
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 center after about 2 minutes delay i.e. when  
the reading interval is reached.  
CARE AND MAINTENANCE:  
Extreme temperatures, vibration and shock should be avoided as these may  
cause damage to the units and give inaccurate forecasts and readings.  
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 units in water.  
Immediately remove all low powered batteries to avoid leakage and damage.  
Replace only with new batteries of the recommended type.  
Do make any repair attempts to the units. Return it to their original point of  
purchase for repair by a qualified engineer. Opening and tampering with the  
units may invalidate their guarantee.  
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.
