Note:
When putting the Weather Station 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
76
them at their final destinations (See Positioning below). Spin the wind vane and tip
the rain gauge to test.
Unwind the cables of the Wind sensor. Connect the Wind sensor to the Thermo1.
hygro transmitter by plugging the connector heads into the sockets of the
Thermo-hygro transmitter. Cord should “click” into place.

First insert the batteries into the Thermo-hygro transmitter and Rain sensor (see
“How to install and replace the batteries into the Thermo-hygro
transmitter“ & How to install and replace batteries into the Rain sensor
below).
Then insert the batteries into the Weather Station (see “How to install and
replace the batteries into the Weather Station” 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 00:00, 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 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 should then be displayed on the Weather Center. If this
does not happen after 45 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 45 seconds, you will need to start
again from step 2.
You may need to check the cable for correct connection and all the components
for correct function by manually turning the wind-gauge by moving the windvane; tilting the rain sensor to hear the impact of the internal moving seesaw,
etc. (see Positioning below).
Time and date shall be manually set (See Manual Setting below).
After the Weather Station 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 868
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 100 metres, provided there are no interfering obstacles
such as buildings, trees, vehicles, high voltage lines, etc.
78
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 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, user 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 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.

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 +25°C and the curr ent value moves to +25°C, the
alarm will be activated (if it has been enabled). Now when the temperature drops to
+24.9°C or below and thereafter again increases to beyond +25°C, the data will be
blinking, but no alarm will be activated. It has to drop to below +24°C (with a pre-set
hysteresis of 1°C) so that the alarm can be produce d again. Hysteresis values for the
various weather data types are given in the following table:
Weather data
Temperature
Humidity
Wind speed
Hysteresis
1°C
3% RH
5 km/h
Note:
The temperature, humidity or wind 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)
103
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:
TENDENCY
Sunny
TENDENCY
TENDENCY
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.
(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.
104
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 4860 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.
THE WEATHER TENDENCY INDICATOR
Working together with the weather icons are the weather tendency indicators (the
upward and downward arrows located on the right hand side of the weather girl icon).
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-
105
pressure is dropping and the weather is expected to become worse.
Therefore, user may see how the weather has changed and is expected to change.
For example, if the indicator is pointing downwards together with cloudy icons, it
means that the last noticeable change in the weather was when it was sunny (the
sunny icon only). Therefore, the next change in the weather will be the cloudy 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.
Air pressure
changes in inHg
Air pressure
changes in hPa
106
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 hPa (+4, +2, 0, -2, -4. “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 Station 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 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/
gust in Beaufort scale

VIEWING 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 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.
109
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.

LOW BATTERY INDICATOR
The low battery indicator of the weather station and the transmitter 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 Station and the transmitters need to be
reset (see note ”Setting up”)
The History data record will be clear after the battery change.
OUTDOOR TRANSMITTER 868 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 100 metres) 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.
122
If (1) the outdoor data are not being received within 30 seconds 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:
1.
2.
3.
4.
5.
The distance of the Weather Station or transmitter/ rain sensor should be at
least 1.5 to 2 metres away from any interfering sources such as computer
monitors or TV sets.
Avoid positioning the Weather Station 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 (868 MHz) may prevent correct signal transmission
and reception.
Neighbours using electrical devices operating on the 868 MHz signal frequency
can also cause interference.
“Visibility” of weather station and transmitter (e.g. through a window) increases
the range.
Note:
When the 868 MHz signal is received, do not re-open the battery compartment cover
of either 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 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 for thermo-hygro transmitter will return to 4.5 seconds (6.25
seconds for rain sensor).
123
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
The Weather Station
The Weather Station has been designed to be hung onto wall or free standing with
the two kinds of foldout stand.
To wall mount
Choose a sheltered place. 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:
1.
2.
Fix a screw (not supplied) into the desired wall, leaving the
head extended out by about 5mm.
Hang the station onto the screw. Remember to ensure that it
locks into place before releasing.
124
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.
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.
125
The Wind Sensor
Wind vane
Vertical
mast
Wind fan
Horizontal
panel
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 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 use staples.
Using PVC pipe or metal as a mast may cause static. Wood is recommended.
126
The Rain Sensor
Horizontal
panel
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).
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.
127
Note:
You will need to be able to access your rain gauge periodically to clean debris and
possible insect nests. Please keep this in mind when mounting.
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 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.
