• 100% solar-powered with built-in rechargeable alkaline
power cell
• High-efficient solar panels maintain operation throughout
all seasons
• Self-emptying bucket
• Transmission range: about 100 meters (Open field, free of

SETTING UP:
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 setup process, place the wireless display and the outdoor
sensors on a surface with 1-3 meters between the sensors and the display. Only use
Alkaline Batteries for the Wireless isplay and Thermo-hygro sensor,
rechargeable batteries may not work.
1. 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 - do not cover with
hands or other objects. Remove the black protective foil
on the solar panel and use the provided plastic reset rod
to gently press the reset button once in the hole on the
bottom of the sensor.
2. Twists open the top of the solar rain sensor. Remove the securing tape from the
seesaw and the black protective cover from the solar panel. Swing the seesaw
once to ‘wake-up’ the rain sensor. The solar rain sensor should then be placed
under a bright environment in order to charge up the rechargeable batteries.
IMPORTANT: Completely reset the rain sensor:
a. Unscrew the battery cover on bottom of the rain sensor and remove the
rechargeable batteries
b. Completely cover the solar panel to
block any light source
c. Wait 20s, then re-insert the 2 x AA
rechargeable batteries and re-screw the
battery compartment back
d. Wait 2s, and uncover the solar panel
e. Swing the seesaw once and put the rain
cover top back.
f. Place the solar rain senor under bright
environment to charge-up the rechargeable
batteries.

3. Insert two "C" size batteries into the thermo-hygro sensor with the correct polarity.
4. Insert two "C" size batteries into the wireless display with the correct polarity.
NOTE: Every time the wireless display 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 display. The thermo-hygro sensor tries
for 7 minutes to sync to the wind sensor and for the rain sensor. If not successful
within 7 minutes, the thermo-hygro sensor will stop looking for the other sensors.
5. Setup troubleshooting: If the sensor data fails to display for any of the outdoor
sensors within 10 minutes, (“- - -“ is displayed), remove the batteries from all
units (except for the Wind Sensor) for 1 minute and start the Setup procedure
again at Step 1 and completely reset the solar Rain Sensor (see Step 2:
Important).
A ITIONAL NOTES FOR THE SOLAR WIN AN RAIN SENSORS MO ES:
I LE MO E
This mode aims to reduce the power consumption of the transmitter. Under this mode,
the sensor stops the transmission of signal, checks the battery voltage and detects the
solar cell condition. The IDLE mode happens if the battery voltage is low.
Note: The sensor will check and charge up the rechargeable battery automatically.
When it detects that the battery voltage is sufficiently charged up and high enough, the
transmission of signal starts again.
STOP MO E
It is the most energy saving mode. Under this mode, the transmitter stops the
transmission of signal. There is no checking of the battery voltage and no detection of
the solar cell condition. The STOP mode happens:
• If the user covers the solar cell for 10 seconds and presses the RESET
button (Wind Sensor).
• If the sensor(s) is (are) placed in the dark environment for 72 hours.
Note:
• To restart the Solar Wind Sensor after placing it in the dark environment for
72 hours, user should place the sensor in a bright environment then spin the
wind cups, or press the RESET button once to wake it up again.
• If the Solar Wind Sensor is stopped by pressed the RESET button, user
must press the RESET button once to wake it up again.
• To restart the Solar Rain Sensor, should swing the seesaw or, follow the
SETTI G UP, Step 2: Important instructions to completely reset the sensor.
IMPORTANT! During the restart process, if the battery voltage is high enough, the
transmission of signal starts again. However, if the battery voltage is low, the sensor(s)

39
enters the IDLE mode. User should place the sensor(s) under a bright environment in
order to charge up the rechargeable batteries.
MOUNTING THE SENSORS AN PLACEMENT OF THE WIRELESS ISPLAY:
IMPORTANT: Ensure that all of the sensor data can be received at the intended
mounting locations before you drill mounting holes. The outdoor sensors have a
wireless range of 100 meters. Keep in mind that the 100 meters range equates to an
open air scenario with no obstructions. Each obstruction (roof, walls, floors, ceilings,
etc.) will reduce the range.
The thermo-hygro sensor measures outdoor temperature & humidity and collects the
data from the wind and the rain sensors and sends all outdoor weather data to the
wireless display, so the thermo-hygro sensor must be within the 100 meters wireless
range of the wireless display. This allows the wind and rain sensors to be placed
relative to the thermo-hygro sensor rather than the wireless display. See Wireless Data
Diagram above.
• The wind and rain sensors must be mounted within the 100 meters wireless range
of the thermo-hygro sensor and on the same side of the house.
• The wireless display must be within the 25 meters wireless range of the USB
transceiver to send weather data to the PC.
If the sensor wireless icons drop from the display as you move them into their
intended locations, the sensors may be too far from the wireless display. Try moving the
wireless display or the sensors closer and wait a few minutes to see if the wireless icons
display again. If the wireless icons are still not displayed after re-positioning the

sensors or the wireless display, press and hold the ▲UP ARROW key for 2 seconds to
re-synchronize the wireless display with the sensors.
WIN SENSOR
The wind sensor must be installed with the front of the sensor (the solar panel)
facing true South, or the reported wind direction will not be accurate. Mount within the
100 meters wireless range of the thermo-hygro sensor and on the same side of the
house. The roof may or may not be an ideal mounting location. Secure the main unit to
the shaft of the mast holder. Use the right-angle adaptor if the wind sensor will be
mounted on a horizontal mast or surface.
Fasten the wind sensor to a suitable mast using the two U-bolts, washers and nuts
included. Note: Mount the wind sensor onto a mast so the wind can reach the sensor
unobstructed from all directions for an accurate reading. The ideal mast is between
15.75mm and 33mm in diameter. The wind sensor DOES OT have replaceable
batteries, it consumes solar power and charges the internal battery pack automatically.
RAIN SENSOR
The rain sensor should be mounted on a level surface in an open area and bright area
within the 100 meters wireless range of the thermo-hygro sensor and on the same side
of the house. Mount the rain sensor at least 0.30 meter off the ground level for optimum
wireless transmission. The rain sensor should be accessible to allow for period cleaning
of debris or insects.
THERMO-HYGRO SENSOR
The thermo-hygro sensor is "weather resistant", but not "water proof". To ensure an
extended life of your sensor, mount it in a semi-covered place out of the elements. An
ideal location for the thermo-hygro sensor is under the eaves on the orth side of the
house to avoid the effects of sunlight. Mount the sensor 0.5 meter down from the eaves
to ensure optimum performance. This way the weather data collected by the sensor will
not be affected by the temperature of the air coming out of the attic.
To wall mount the thermo-hygro sensor, fix the wall holder onto the desired wall using
the included screws, plug the sensor firmly into the wall holder and replace the rain
cover if it is not already in place. Note: After mounting the units, if the weather data is
not received, press and hold the ▲UP ARROW key for 2 seconds to synchronize the
wireless display to the sensors.

WEATHER ALARM OPERATIONS
The Weather alarms can be set when certain weather conditions are met according to
your requirements. For example, you can set the thresholds for the outdoor temperature
to +40°C (high) and -10°C (low), while enabling the high alarm and disabling the low
alarm (i.e. temperatures <-10°C won’t trigger alarm, but temperatures >+40°C will).
• If the value meets the condition for high alarm or low alarm, the buzzer will ring for 2
minutes and the value will blink, along with the corresponding icon ("HI AL"/ "LO AL").
• Press any key to stop a ringing alarm.
• The high and low alarms can be switched On/Off independently, according to your
needs.
• If at any time during the alarm setting process you would like to exit alarm setting
mode, press the MI /MAX key or wait for about 30 seconds and the display will
return to normal display mode automatically.
• In normal display mode, press the ALARM key to enter ALARM mode. Subsequent
presses of the ALARM key will advance to the next weather alarm section.
Note: Weather alarms can also be set from the Heavy Weather Pro software.
Consult the Heavy Weather Pro User’s Guide for instructions.
