Introduction
Thanks for choosing our Aspect Wi-Fi Solar Pro. This
system gathers and automatically uploads accurate
and detailed weather data to Weather Underground,
which allows weather observers to upload their local
weather data. This product offers professional weather
observers or serious weather enthusiasts robust
performance with a wide range of options and sensors.
You will get your own local forecast, high/lows,
totals or averages and graphs for virtually all weather
variables without using a desktop computer.
The Aspect Wi-Fi Solar Pro includes a
6-in-1 Wireless Outdoor Sensor which transmits
outdoor temperature, humidity, wind speed, wind
direction, rainfall and UV with solar power. Also,
the included wireless indoor sensor, transmits
your indoor temperature and humidity to the
Main Console. Both sensors are fully assembled
and calibrated for your easy installation. They
send data at a low power radio frequency to the
Main Console from up to 150m away (line of sight).
In the Main Console, a high-speed processor is
embedded to analyse weather data and publish it to
Weather Underground through your home Wi-Fi
router. The Main Console can also synchronise with an
internet time server to keep the time and weather data
time stamp of high precision. The wide-viewing-angled
with high-contrasted LCD display shows informative
weather readings with advanced features, such
as high/low alert alarm, different weather index,
multi-functional bar chart and maximum/minimum
records. With the built-in sunrise/sunset and moon
phase feature, this system is truly a personal yet
professional weather station for your own backyard.
This instruction manual contains useful information
on the proper use and care of this product. Please
read this manual through to fully understand and
enjoy its features, and keep it handy for future use.

Dew Point: The dew point is the temperature below which the water vapour in air at constant
barometric pressure condenses into liquid water at the same rate at which it evaporates. The condensed
water is called dew when it forms on a solid surface. The dew point temperature is determined
by the temperature and humidity data from the 6-in-1 Wireless Outdoor Sensor.
Weather Forecast
The Main Console is built with a sensitive pressure sensor, by which the proven sophisticated software
forecasts the weather of the next 12~24 hours within a 30~50km (19~31 miles) radius.

Barometric Pressure
Barometric Pressure is the atmospheric pressure is the pressure at any location of the Earth caused by the weight
of the column of air above it. One atmospheric pressure refers to the average pressure and gradually decreases as
altitude increases. Meteorologists use barometers to measure atmospheric pressure. Since variation in atmospheric
pressure greatly affected by weather, it is possible to forecast the weather by measuring the changes in pressure.
To set the barometer unit and select the Wind Display Mode:
1. In Normal Mode, press BARO to change the barometer unit in this sequence: hPa inHg mmHg
2. In Normal Mode, press and hold BARO to switch between ABSOLUTE/RELATIVE display.

1. Obtain the atmospheric pressure data of sea level
(it is also the relative atmospheric pressure data of
your home area) through the local weather service,
internet or any weather information source.
2. In Normal Mode, press and hold
BARO for 2 seconds until ABSOLUTE
or RELATIVE icon flashes.
3. Press or to switch to Relative Mode.

6. Press BARO to save and exit.
When you change the RELATIVE
atmospheric pressure value, the weather
indicators will change along with it.
The built-in barometer detects the environmental
absolute atmospheric pressure changes. Based
on the data collected, it predicts the weather
conditions in the forthcoming 12 hours. The
weather indicator will change according to
the detected absolute atmospheric pressure
after operating the clock for 1 hour.
The RELATIVE atmospheric pressure is based
on the sea level pressure you entered but it
will change with the absolute atmospheric
pressure after operating the clock for 1 hour.
