SETUP INSTRUCTIONS STEP BY STEP
IMPORTANT: Make sure to observe the correct polarity when inserting batteries. The "+" markings on the
batteries must line up with the diagrams inside the battery compartments. Inserting the batteries
incorrectly may result in permanent damage to the units. During the initial setup process, place the
wireless weather station and the outdoor sensors on a surface with 5-10 feet between each sensor and
the weather station. Only use Alkaline batteries, rechargeable batteries may not work.
STEP 1: Complete initial setup on a table with all components within 10 feet of each other.

Page| 8
Press Reset Button on
Bottom of Wind Sensor
(Solar Panel Must Face
Light)
STEP 2:
•It is important to allow sufficient light to reach the solar panel while activating the wind sensor. Make
sure the lights are on in the setup room and the solar panel is facing a 60W light bulb or brighter.
•Ensure the solar panel is not covered, and then remove the black protective foil on the solar panel.
Remove the tape covering the reset hole.
•Use the provided plastic reset rod to gently press the reset button once in the hole on the bottom of
the sensor.
STEP 3: Insert two "AA" size batteries into rain sensor with correct polarity.
STEP 4:
•Insert two "C" size batteries into the thermo-hygro sensor with the correct polarity.
Note: Allow all sensors to run for two minutes before inserting batteries in the weather station.
STEP 5:
•Insert three "C" size batteries into the wireless weather station with the correct polarity.
Note: Every time the wireless weather station receives data from the
sensors, the wireless icons will blink once and then return to solid if the last
transmission was successful. A wind speed or rainfall amount that reads "0"
does not mean reception failure. It means that there was no wind or rain at the
time of the last measurement. The thermo-hygro sensor syncs with the wind
and rain sensors and sends all outdoor sensor data to the weather station. The
thermo-hygro sensor tries for 4 minutes to sync to the wind sensor and then 4
minutes for the rain sensor. If not successful within 4 minutes, the thermo-
hygro sensor will stop looking for the other sensors.
•Wait 10 minutes for reception from all sensors before setting time and date or mounting sensors
outside.
STEP 6: Set Time and Date. See “Program Menu”below.
Setup Troubleshooting: If the sensor data fails to display for any of the outdoor sensors within 10
minutes (“- - -“are displayed), remove the batteries from all units for 1 minute and start the Setup
procedure again at Step 1.

HYSTERESIS

Page| 18
To compensate for fluctuation of the weather data (which may cause
the weather alarm to ring constantly if the measured reading is close to
the alarm 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
temperature reaches 77°F, the alarm will be activated. If the
temperature then drops to 76.8°F (a change of less than 1.8°F) and
then increases to 77°F again, the data will blink, but no alarm will be
activated.
The temperature would have to drop 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 table.
Note: The temperature or humidity data will keep flashing even after the weather alarm has been
switched off by a button press. The flashing value indicates that the current weather condition is out of the
pre-set weather alarm limit(s).

WEATHER FORECASTING ICONS
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 Station to register. You may adjust the "sensitivity" of the pressure change check in the
setting mode–see WEATHER TENDENCY SENSITIVITY in the manual settings above.
The displayed icon 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 set up, readings for weather forecasts should be disregarded for the next 48-60 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 Station
has been designed for use. 75% accuracy is comparable to the best meteorological forecasting rate. In
areas that experience sudden changes in weather (for example, from sunny to rain), the Weather Station
will be more accurate compared to use in areas where the weather is stable most of the time (for
example, mostly sunny).
If the 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), discard the weather forecast for
the next 48-60 hours. The Weather Station may mistake the new location as being a possible change in
air-pressure when really it is due to the slight change of altitude.
WEATHER TENDENCY INDICATOR
Working together with the weather icons is the weather tendency indicators (arrows 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 the indicator points downwards, the air-
pressure is dropping and the weather is expected to become worse.
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, either the
upward or downward tendency arrow will be displayed until the tendency changes again.

AIR PRESSURE HISTORY GRAPH
The LCD shows the relative air pressure value and the air pressure history on a bar graph.
Press the SET button to toggle between Mode1 and Mode2 of the display.
•Mode 1:The bar graph displays the air pressure history of the
past 24 hours in seven steps. The horizontal axis represents the
last 24 hours of air pressure recording (-24, -18, -12, -8, -6, -3 and
0 hour).
•Mode 2:The bar graph displays the air pressure history of the
past 72 hours in seven steps. The horizontal axis represents the
last 72 hours of air pressure recording (-72, -48, -36, -24, -12, -6
and 0 hour).
The vertical bars are plotted at each of the seven steps and give the trend over the recorded period. The
0 hour vertical bar will always display at the midline height to indicate the current air pressure. The
varying height of bars in other columns on the graph indicates a relative change in air pressure up or
down from the 0 hour.
New pressure measurements are compared to previously recorded pressure measurements. The
pressure change is expressed by the difference between the current ("0h") and the past readings in
divisions of ±0.06 inHg or ±2 hPa. If the bars are rising from left to right, this indicates that the weather is
getting better due to an increase in air pressure. If the bars are falling from left to right, this indicates that
the weather is expected to get worse due to a drop in air pressure.
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. 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 should be discarded.
Note: The bar graph will scroll right to left regularly to prevent LCD burnout.
