Introduction
Congratulations on your purchase of the TE821 Weather Station. The weather station consists of
a main console unit with remote sensors which collect and transmit a wide range of weather data,
including outdoor temperature, humidity, wind speed and direction.
Main Console Unit
The main console unit features a radio-controlled atomic precision clock with alarm and weather
forecast. It measures indoor temperature and humidity, and displays weather data collected by the
remote weather sensors. It also provides indication of the indoor/outdoor temperature, pressure and
humidity trends, and celestial information such as moon phase, and sunrise/set times.
The main console unit stores around 200 weather records without a computer connection. When
linked to a computer using the USB cable and software provided, an unlimited number of weather
records can be displayed and saved onto the computer.
Remote Weather Sensors
The remote weather sensors include a thermo-hygrometer and anemometer (wind sensor) and rain
sensor. All data collected by the sensors is transmitted to the main console unit by wireless RF, with
a range up to 100 meters (open area) for thermo-hygrometer and 30 meter (open area) for
anemometer. The weather station supports a maximum of 5 thermo-hygrometers, allowing 5
channels of temperature/humidity display.
