Note:  
HYSTERESIS  
The High and Low outdoor humidity alarm can be set On/Off independently according  
to your needs.  
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 (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  
In case the humidity value meets the condition for high alarm or low alarm, the value

For every sudden or significant change in the air pressure, the weather icons will  
update accordingly to represent the change in weather.  
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.  
drops to +76.8°F (24.9°C) or below and thereafter again increases to beyond +77°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 1.8°F (1°C)) so that the alarm can be  
produced again. Hysteresis values for the various weather data types are given in the  
following table:  
(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.

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 TENDENCY INDICATOR  
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.  
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 is 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.

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 station to collect air pressure  
data at a constant altitude and therefore result in a more accurate forecast.

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.  
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)  
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.  
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.  
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.  
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  
Air pressure  
changes in inHg  
Air pressure  
changes in hPa  
in Beaufort scale  
Wind chill in °F or °C  
Wind Speed in mph, km/h or m/s  
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.  
Text showing wind speed

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

flashing on the LCD for time alarm.  
Note:  
On the other hand, when the buzzer is turned off and any weather alarm is activated,  
the particular weather digits will flash to show user that the weather condition is being  
out of the preset threshold value, yet the buzzer will not sound.  
After battery change, both the Weather Center and the Thermo-hygro sensor  
need to be reset (see note ”Setting up”)  
The total rainfall value is counted  
from this time and date  
The History data record will be clear after the battery change.  
To switch off the buzzer:  
1.  
In normal display mode, press and hold the SET key until the icon "BUZZER

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

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.  
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.  
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.  
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  
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.  
Weather Center  
The Weather Center has been designed to be hung onto wall or free standing with the  
foldout stand.

5.  
To wall mount  
Choose a sheltered place, such as under the eve of a roof.  
Avoid direct rain and sunshine.  
Wind Sensor  
Wind vane  
Before wall mounting, please check that the outdoor  
temperature and humidity values can be received from the  
desired locations. To wall mount:  
Note:  
Vertical  
mast  
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  
contacts and force a false reset. Should this happen accidentally then reset all units  
(see Setting up above) otherwise transmission problems may occur.  
1.  
Fix a screw (not supplied) into the desired wall, leaving  
the head extended out the by about 5mm.  
2.  
Hang the Center onto the screw. Remember to ensure  
that it locks into place before releasing.  
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.

POSITIONING  
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” (16 mm) to 11/4” (33 mm)).  
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.  
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.
