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.

Installing your weather station
Setting up the Remote Weather Sensors
Before starting up the main console unit, setup all the remote sensors rst.
When placing the sensors, make sure that they are within receiving range of the console unit. Ideally
they should be within the line of sight of the console unit. Transmission range may be affected by
trees, metal structures and electronic appliances. Test reception before permanently mounting your
weather station.
Also make sure that the sensors are easily accessible for cleaning and maintenance.
The remote sensors should be cleaned on a weekly basis, since dirt and debris will affect sensor
accuracy.
Placement tips:
- The sensor should be mounted in an area free of shadows or reections of sunlight by nearby
coverings and objects.
Setting up the Thermo-Hygro Sensor(s)
1. Open the latch at the base of the thermo-hygro sensor.
2. Set the channel with a slide switch.
3. Insert two 2 x UM-3 or “ AA” size 1.5V batteries.
4. Use a pin to press the “RESET” key which is in the battery compartment of thermo-hygro
Sensors after LED ash.
5. Replace the latch and mount unit at desired location.
Placement tips:
- The thermo-hygro sensor should be in an area with free air circulation and sheltered from direct
sunlight and other extreme weather conditions. Place the unit in a shaded area, such as under a
roof.
- Use the wall mount and ttings provided if mounting the unit on a vertical surface.
- Avoid placing the sensor near sources of heat such as chimneys.
- Avoid any areas which collect and radiate heat in the sun, such as metal, brick or concrete
structures, paving, patios and decks.
- Ideally, place the sensor above natural surfaces such as a grassy lawn.
- The international standard height for measurements of air temperature is at 1.25m (4 ft) above
ground level.
Setting up the Anemometer (wind sensor)
1. Assemble the wind cups and wind vane to the anemometer arm
2. Attach the assembled anemometer to the base.
3. Insert two 2 x UM-3 or “AA” size 1.5V batteries into the battery holder in the base.
4. Mount the anemometer onto a vertical surface, using the ttings provided.
5. To allow the main console unit to nd the direction which the wind vane is oriented, the
following procedures are required:
i. Insert the batteries
ii. Point the wind vane towards the north. Use a compass or map if necessary.
iii. Use a pin to press the “SET” key which is in the battery compartment of the wind sensor.
Note: Above procedure must be repeated for changing battery.

Placement tips:
- Check that wind can travel freely around the anemometer and is not distorted by nearby buildings,
trees or other structures.
- For better results, place the anemometer at least 3m above local structures and obstacles. The
ground creates a frictional effect to wind ow and will attenuate readings.
- Aim for maximum exposure of the anemometer to the commonest wind directions in your area.
- The ofcial mounting location for anemometers is 10m (33 ft) above ground level in a clear
unobstructed location.
Setting up the Main Console Unit
1. Open the latch at the back of the main console unit.
2. Insert 4 x UM-3 or “AA” size 1.5V batteries according to the polarities shown.
3. Reattach the latch.
4. You are highly recommended to connect the AC/DC adaptor. For the feathure of the automatic
backlight control function, the AC/DC adaptor must be used.
5. If placing the console unit on a table or horizontal surface, fold out the table stand and adjust to
the optimal viewing angle.
6. If mounting the console unit on a wall or vertical surface, fold the table stand back into the unit
and use the tting provided.
Placement tips:
Make sure that the console unit is within receiving range of all remote sensors. Ideally
sensors should be within the line of sight of the console unit. Transmission range may be affected by
trees, metal structures and electronic appliances. Test reception before permanently mounting your
weather station.
The console unit measures indoor temperature, humidity, pressure and receives signals from all
remote sensors and radio-clock broadcasts. Avoid placing the console unit in the following areas:
- Direct sunlight and surfaces which radiate and emit heat.
- Near heating and ventilation devices, such as heating ducts or air conditioners.
- Areas with interference from wireless devices (such as cordless phones, radio headsets, baby
listening devices) and electronic appliances.
Starting up the Main Console Unit
Once the console unit is properly powered, the display will start showing some data and weather
parameters. Wait for a few minutes for the console to nish self-calibration and for the sensor
readings to show up.
If “---” is still displayed for the sensor reading(s), check the wireless transmission path and the bat-
teries for the corresponding sensor.

Activating Main Console Unit to Search for All Remote Sensor Signals
The main console unit may be manually activated to search for signals from all remote sensors.
Press and hold DOWN to enforce a search.
Wind Mode
The wind direction is shown by an animated compass display. Its angle can be displayed as compass
points (i.e. NW) or in bearings from the north (i.e. 22.5º).
The upper left of the wind display can be set to indicate the temperature at the anemometer or the
temperature adjusted with a wind chill factor.
The lower left of the wind display indicates the average wind speed for the last 10 minutes, as well
as gust, wind speed alert and gust alert information. It can also show records of the maximum values
of wind speed and gust attained for the current day.
The wind speed and gust alert functions can be programmed to sound if the wind speed or gust
exceeds a pre-congured limit. The wind speed may be displayed in km/h, mph, m/s or knots.
Note: The wind speed alert has a 5 mph hysteresis and the wind gust speed alert has a 7 mph hyster-
esis. The hysteresis is to prevent the alerts from sounding constantly due to small uctuations near
the alert value. This means that after the wind speed reaches the alert value, it will have to fall below
the alert value plus the hysteresis to deactivate the alert.
Accessing Wind Mode
From the main console unit: Press UP or DOWN until the WIND icon on the display starts
ashing.
Conguring Wind Display
In Wind Mode, each press of SET rotates display between:
- Temperature with wind chill, wind direction in bearings
- Temperature with wind chill, wind direction in compass points
- Temperature at anemometer, wind direction in compass points
- Temperature at anemometer, wind direction in bearings

Maintenance
Changing Batteries
The battery statuses of the sensors are checked every hour. If the low battery indicators light up,
replace the batteries for the corresponding unit immediately.
Changing Batteries for the Main Console Unit
1. To avoid losing data and records, connect the AC/DC adaptor to the main unit rst.
2. Remove the latch at the back and replace all batteries. Do not mix old and new batteries.
3. Replace the cover.
Changing Batteries for the Remote Sensors
1. Replace the batteries following the setup instructions for the corresponding sensor.
2. When the batteries are properly installed, the sensor will resume sending signals to the main
console unit.
To enforce a search immediately for all remote signals, press and hold DOWN on the main
console unit.
Cleaning
The main console unit and outer casings for the remote sensors can be cleaned with a damp cloth.
Small parts can be cleaned with a cotton tip or pipe-cleaner.
Never use any abrasive cleaning agents and solvents. Do not immerse any units with electronic parts
in water or under running water.
Anemometer
- Check that the wind vane and wind cups can spin freely and are free from dirt, debris or spider
webs.
Troubleshooting
The display shows dashes “---” for weather parameter(s)”
The display will show “---” when the wireless link is lost with the remote sensor for the following
periods:
Thermo-hygro Sensor – 15 minutes
Anemometer (Wind Sensor) – 15 minutes
Check or replace the batteries for the corresponding sensor. Then press and hold DOWN to enforce
a search for all remote signals.
If the above does not solve the problem, check the wireless transmission path from the corre-
sponding sensor to the main console unit and change their locations if necessary.
Although wireless signals can pass through solid objects and walls, the sensor should ideally be
within the line of sight of the console unit.
The following may be the cause of reception problems:
- Distance between remote sensor and main console unit too long. (Maximum transmission distance
in open area conditions is 100m)
- Signal shielding materials such as metal surfaces, concrete walls or dense vegetation in the path of
transmission.
- Interferences from wireless devices (such as cordless phones, radio headsets, baby listening
devices) and electronic appliances.
The weather readings do not correlate with measurements from TV, radio or ofcial weather reports.”
Weather data can vary considerably due to different environmental conditions and placement of
weather sensors.
Check the placement tips included in this manual to site your sensors in the best possible way.
“The weather forecast is inaccurate.”
The weather forecast is a prediction of weather after 12-24 hours, and may not reect current
weather conditions.
PRECAUTIONS
This product is engineered to give you years of satisfactory service if you handle it carefully. Here
are a few precautions:
1. Do not immerse the unit in water.
2. Do not clean the unit with abrasive or corrosive materials. They may scratch the plastic parts and
corrode the electronic circuit.
3. Do not subject the unit to excessive force, shock, dust, temperature or humidity, which may result
in malfunction, shorter electronic life span, damaged battery and distorted parts.
