1.  Introduction 
 
Thank you for purchasing this Professional Remote Weather Station. 
 
Designed for everyday use, the weather station will prove to be an 
asset of great value for your personal use in the home or office. 
  
Please read this instruction manual thoroughly to fully understand the 
correct operation of your weather station and benefit from its unique 
features. 
 
2.  Intended Use  
 
Weather Station 
The base station measures the indoor environment of its surrounding 
area and receives weather data from the following three outdoor 
sensors: 
1)  Thermo-Hygro Sensor 
2)  Wind Sensor 
3)  Rain Sensor 
 
The received data is continuously updated to bring you the latest 
weather information on the base station’s LCD.  The outdoor thermo-
hygro sensor is the main data communication unit since both the wind 
and rain sensors are connected to the thermo-hygro sensor for 
operating power and rely on it to communicate to the base station.  
Weather data sent from the thermo-hygro sensor can be done by 
wireless 433MHz transmission (up to 330ft in open space) or by cable 
connection. 
 
Using the enclosed 6.5ft computer cable and CD-ROM, you can 
install the Heavy Weather software to your PC and access the latest 
weather information from your PC and upload up to 175 sets of 
recorded weather data received by the base station.  Recorded data 
can be used to generate statistics and charts onto your spreadsheets 
(175 sets of data is stored in the base even if the PC is switched 
OFF).  The software itself does not set any limits as to how many data 
sets can be transferred to PC. 
 
This weather station is designed to work easily with your PC, simply 
connect and disconnect the PC cable at any time.

Features of the Thermo-Hygro Sensor 
The thermo-hygro sensor measures the outdoor temperature and relative 
humidity.  It also collects the readings from the rain and wind sensors 
before transmitting the data to the base station by wireless 433MHz or by 
the 32ft cable included in this set. 
 
Features of Wind sensor 
The wind sensor measures wind speed and wind direction and sends the 
data to thermo-hygro sensor, which in turn transmits the data to the base 
station.  Operating power is taken from the thermo-hygro sensor using a 
32ft cable connection. 
 
Features of Rain sensor 
The rain sensor measures the rainfall and sends the data to thermo-hygro 
sensor, which in turn transmits the data to the base station.  Operating 
power is taken from the thermo-hygro sensor by a 32ft cable connection.
