In this time the intelligent weather station and remote
temperature/humidity sensor will begin to communicate with each other
and the display will show the temperature/humidity, outdoor
temperature/humidity. If the intelligent weather station does not display
all information after the 15 minutes, please retry the set up as stated
above. After all information has been displayed for 15 minutes you can
place your sensors outdoors and set your time.
Important Notes on Set-up and Operation
•
•
•
The remote temperature/humidity sensor should be placed in a
dry, shaded area.
Fog and mist will not harm your remote temperature/humidity
sensor but direct rain must be avoided.
The remote temperature sensor should be placed in a dry,
shaded area. The remote temperature sensor has a range of 330
feet. Keep in mind that the 330 feet is in open air with no
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 wireless weather station receiver 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 foot
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.
•
The remote temperature/humidity sensor transmits a signal every
4 seconds – with variations during updating periods. After the
batteries have been installed, the intelligent weather station will
search for the signal for the duration of 45 seconds. If there is no
temperature or humidity reading in the OUTDOOR LCD after 5
minutes, make sure the units are within range of each other, or
repeat the battery installation procedure.

•
If a button is pressed before the intelligent weather station
receives the signal from the remote temperature/humidity sensor,
you will need to follow the battery installation procedure again.
To complete the set up of your new wireless intelligent weather station
after the 5 minutes have passed, please follow the steps in the “Manual
Settings” section.
Note:
If the outdoor sensor signal reception is not successful on the first
frequency of 915MHz for 45 seconds, the frequency is changed to
920MHz, and the learning is tried for another 45 seconds. If it is still not
successful the reception is tried for 45 seconds on 910MHz. This will
also be done during re-synchronization.

a random security code is assigned by the sensor at start-up, and this
code must be received and stored by the intelligent weather station in
the first few minutes 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 facility.
ABOUT WWVB (Radio Controlled Time)
The NIST (National Institute of Standards and Technology—Time and
Frequency Division) WWVB radio station is located in Ft. Collins,
Colorado, and transmits the exact time and date signal continuously
throughout the United States at 60 kHz. The signal can be received up
to 2,000 miles away through the internal antenna in the intelligent
weather station. However, due to the nature of the Earth’s Ionosphere,
reception is very limited during daylight hours. The intelligent weather
station will search for a signal every night when reception is best. The
WWVB radio station derives its signal from the NIST Atomic clock in
Boulder, Colorado. A team of atomic physicists is continually measuring
every second, of every day, to an accuracy of ten billionths of a second
per day. These physicists have created an international standard,
measuring a second as 9,192,631,770 vibrations of a Cesium-133 atom
in a vacuum. For more information on the atomic clock and WWVB
please see the NIST website at

WEATHER ALARM OPERATIONS
WEATHER ALARMS
The Weather alarms are selectable for when certain weather conditions
are met according to the user’s requirements. For example, the user can
set the thresholds for the outdoor temperature to +104°F (+40ºC) (high)
and +14ºF
(-10°C) (low), while only enabling the high alarm and disabling the low
alarm (i.e. temperatures < +14ºF (-10°C) won’t trigger alarm, but
temperatures > +104ºF (+40°C) will).
Alarm setting
Minimum
Maximum
Outdoor Temperature
-40°F (40ºC)
+139.8°F (59.9ºC)
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 user set level, a hysteresis function has been implemented for each
weather alarm. For example, if the high temperature alarm is set to
+77°F (+25°C) and the current value moves to +77°F (+25°C), the alarm
will be activated (if it has been enabled). Now when the temperature
drops to +76.8°F (+24.9°C) or below and thereafter again increases to
beyond +78°F (+25°C), the data will be blinking, but no alarm will be
activated. It has to drop to below +75.2°F (+24°C) (with a pre-set
hysteresis of 2ºF (1°C)) so that the alarm can be produced again.
Hysteresis values for the various weather data types are given in the

WEATHER FORECAST AND WEATHER TENDENCY:
WEATHER FORECASTING ICONS:
There are 4 weather icons in the fourth section of LCD which can be
displayed in any of the following combinations:
Cloudy with
sunny
Cloudy
Rainy
Sunny
intervals
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 intelligent weather
station to register. However, if the icon displayed is a sun or rainy, 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.
The change of weather forecast icon is in agreement with the
relationship between current relative pressure and the pressure change
in the last three hours.
If the weather is changing, both old weather icon and new weather icon
will be shown with a weather tendency indicator (animated arrows). If
the weather has not changed within 6 hours, only the new weather icon
in the middle display will be shown.

Examples of changing weather icons:
Note:
After initial set up of the intelligent weather station with the setting of the
relative value, readings for weather forecasts should be disregarded for
the next 12-24 hours. This will allow sufficient time for the intelligent
weather station to collect air pressure data at a constant altitude and
therefore result in a more accurate forecast.
If the intelligent 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), set again the relative air
pressure value, and discard the weather forecast for the next 12-24
hours. By doing this, the intelligent 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.
AIR PRESSURE TENDENCY INDICATOR
The air pressure tendency indicators are located on the left side of the
air pressure display, below the weather icons, and they work
independently from the weather forecast icons. The air pressure
tendency indicator pointing upward or downward directions is displayed
based on comparing the difference of the air pressure recorded during a
full hour time frame.
Note:
•
An upward air pressure tendency indicator means that there is an
increase in air pressure within the past 4 hours.
•
A downward air pressure tendency indicator means that there is
an decrease in air pressure within the past 4 hours.

AIR PRESSURE
The fifth section of the LCD shows the relative air pressure and the air
pressure history.
Air pressure
changes in hPa
Air pressure over the last 12 hours
The reference relative air pressure can be set between 28.35 to 30.72
inHg (960 to 1040hPa). See “Relative pressure value setting” in
manual setting.
BAR GRAPH DISPLAY
You may select to display the history of the air pressure in the form of a
graph consisting of vertical bars on the intelligent weather station LCD.
AIR PRESSURE HISTORY
The bar graph of the electronic barometer shows the air pressure history
for the past 12 hours in 7 steps.
4.5hPa

The horizontal axis represents the last 12 hours air pressure recordings
(-12, -6, -5, -4, -3, -2, -1, and 0 hour, from right to left). The bars are
plotted at each of the 7 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 (4.5, 3, 1.5,
“0” represents the current air pressure). Each change (±1.5, ±3, ±4.5;
the other values are not shown on the vertical axis but can be
determined) shows in inches of mercury (hPa), how high or low the past
air pressure was as compared to the current one. Rising bars indicate
the weather is getting better due to an increase in air pressure. A
downward sloping bars 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 bar to
the left.
Note:
For accurate barometric pressure trend, the intelligent weather station
should operate at the same altitude. For example, it should not be
moved from the ground to the second floor of the house. Should the unit
be moved to a new location, discard readings for the next 48 – 60 hours.
LOW BATTERY INDICATOR
The low battery indicator will be displayed in the LCD when the battery
power of the intelligent weather station is low. It is recommended to
replace the batteries in all units on an annual basis to ensure optimum
accuracy of the intelligent weather station.
Note: After battery change, both the intelligent weather station and the
sensor(s) need to be reset (see note ”Setting up”)
WEATHER INFORMATIONDISPLAY
The weather information display located at the last section of the LCD
will display the weather forecast based on data received from channel 1
and the air pressure.

REMOTE TEMPERATURE/HUMIDITY SENSOR / 915MHZ
RECEPTION CHECK
The outdoor temperature and humidity is measured and transmitted
about every 4 seconds.
The transmission range of the remote temperature/humidity sensor may
be affected by the ambient temperature. At cold temperatures the
transmitting distance may be decreased. Please bear this in mind when
placing the sensor.
The remote temperature sensor should be placed in a dry, shaded area.
The remote temperature sensor has a range of 330 feet. Keep in mind
that the 330 feet is in open air with no 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 wireless weather station receiver 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 foot 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.
25
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
If the outdoor temperature and humidity data are not being received
within 2 minute after setting up (or the outdoor display show “--.-“ in the
outdoor section of the intelligent weather station after
failed attempts during normal operation). Please check the following
points:
1.
The distance of the intelligent weather station or remote
temperature/humidity sensor should be at least 3 to 6 feet (1.5 to
2 meters) away from any interfering sources such as computer
monitors or TV sets.
2.
3.
Avoid positioning the intelligent 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 (915MHz) may prevent
correct signal transmission and reception.
3.
4.
Neighbors using electrical devices operating on the 915MHz
signal frequency can also cause interference.
“Visibility” of the intelligent weather station and remote
temperature/humidity sensor (e.g. through a window) increases
the range.
Note:
When the 915MHz signal is received, do not re-open the battery cover
of either the remote temperature/humidity sensor or the intelligent
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.
If no reception is possible despite the observation of these factors, all
system units have to be reset (see Setting up).
POSITIONING THE INTELLIGENT WEATHER STATION:
The intelligent weather station has been designed to be hung on a wall
or free standing.
For Free standing:
Simply attached the stand to the bottom of the unit and
place onto a flat surface.

Before wall mounting, please check that the outdoor temperature and
humidity values can be received from the desired locations.
To wall mount:
1.
Fix a screw (not supplied) into the desired wall,
leaving the head extended out the by about 0.2”
(5mm).
2.
Fold the stand of the intelligent weather station
by pushing inward and hang it onto the screw.
Remember to ensure that it locks into place
before releasing.
POSITIONING THE REMOTE
TEMPERATURE / HUMIDITY SENSOR:
The remote temperature/humidity sensor can be placed onto any flat
surface or wall mounted using the bracket which doubles as a stand or
wall mount base.
Table stand/wall
mount bracket
To wall mount:
1.
Secure the bracket onto a desired wall using the screws and
plastic anchors.
2.
Clip the remote temperature/humidity sensor onto the bracket.
Note:
Before permanently fixing the remote temperature/humidity sensor wall
base, place all units in the desired locations to check that the outdoor
temperature and humidity readings are receivable. In event that the
signal is not received, relocate the remote temperature/humidity sensor
or move them slightly as this may help the signal reception.

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.
