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
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.
4.
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 transmitter.
The outdoor temperature, humidity wind chill and wind speed should then be
5.
6.
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.
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).
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 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. 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 transmitter 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 :
•
After batteries are installed in the transmitter, install the batteries in the weather
center to receive the signal from the transmitter 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 this transmitter.
In this case, user will need to reinstall the batteries from the transmitter to redo
set-up procedure.
•
After batteries are installed, there will be synchronization between weather
center and the transmitter. 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.

•
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:
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.
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:
10
1.
2.
3.
4.
Uninstall the rain cover of the transmitter.
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.
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 on an annual basis 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.

buzzer will ring for 2 minutes. User may press any key to stop the sound.
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
Wind speed
Hysteresis
1.8°F
3% RH
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)
31
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
Sunny
TENDENCY
Cloudy with sunny
intervals
TENDENCY
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.
32
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 1224 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 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.
33
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.
34
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.
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.
35
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
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.
•
Wind direction (shown on the a compass scale of 16 divisions) and wind speed
in Beaufort scale
•
Wind chill in °F or °C

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 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 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.

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.
47
OUTDOOR TRANSMITTER 915 MHz RECEPTION
The outdoor temperature, humidity, wind data and rainfall are transmitted from the
Thermo-hygro sensor every 4.5 seconds. The Weather Center will then be
synchronized to the Thermo-hygro sensor to receiver outdoor data. The transmission
range (up to 330 feet) of the Outdoor 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 transmitter.
If the outdoor data are not being received within 30 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.
The distance of the Weather Center or transmitter should be at least 5 to 6.5
feet 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, speakers, or cordless
phones 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.
5.
“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 transmitter or Weather Center, as the batteries may spring free from the
48
contacts and force a false reset. Should this happen accidentally 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 will return to 4.5 seconds.
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 station 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
Choose a sheltered place, such as under the eve of a roof. Avoid direct rain and
sunshine.
Before wall mounting, please check that the outdoor temperature and humidity values
can be received from the desired locations. To wall mount:
49
1.
2.
Fix a screw (not supplied) into the desired wall, leaving the
head extended out the by about 5mm.
Hang the Center onto the screw. Remember to ensure that
it locks into place before releasing.
Thermo-hygro Sensor
Rain Cover
Main Unit
Wall Bracket
50
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
51
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 station.
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).
52
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 station
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 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.
