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 under-
stand the features and functions so that you can enjoy the
safe and correct operation of this unique product.
2. Intended Use
Weather Station
The base station measures the indoor environment of its
surrounding area and receives weather data from the follow-
ing 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
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 trans-
mission (up to 100 meters in open space) or by cable connec-
tion.
Using the enclosed 2 meter computer cable and CD-ROM,
you can install the Heavy Weather software to your PC and
upload all the received weather data from the base station.
Access the latest weather information from your PC and
upload up to 175 sets of recorded weather data by the base
station and generate useful statistics and charts onto your
52

53
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 that can be transferred to PC.
This weather station is designed to work easily with your PC.
There are no tedious requirements to turn your PC ON or
OFF, 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 10 meter 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 10 meter 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 10 meter cable connection.

5. Setting up
Firstly, choose to use the adaptor (included in this set) or
batteries for operation. Both these methods allow for opera-
tion of using wireless 433MHz transmission or cable connec-
tion between the base station and the sensors and setting up
for both methods is as follows:
Base Station:
Socket for
Adaptor
57
Battery
compartment
PC COM
Port
Socket for sensor

Setting up using batteries:
Battery
Compartment
Battery Cover
Thermo-Hygro Sensor
Sensor
sockets
Sensor
sockets
Important: To avoid operating problems, please take note
of battery polarity if inserting any batteries
1) Pull away the rain cover of the thermo-hygro sensor to
reveal the three sockets (for the wind sensor, rain sensor
and the base station)
2) Connect the attached cables of wind and rain sensors to
the corresponding sockets of the thermo-hygro sensor by
clicking them into place
3) Open the battery cover of the thermo-hygro sensor
located below the three sockets and insert 2 x AA, IEC
LR6, 1.5V batteries and close the cover
4) Open the base station’s battery cover located at the back
of the unit and insert 3 x AA, IEC LR6, 1.5V batteries into
the battery compartment and close the battery cover
58

Setting up using the AC adaptor:
1) Power up all the sensors as described in setting up using
batteries above
2) Using the AC adaptor (included), plug it into the mains
outlet and power up the base station by inserting the
adaptor jack into the 6.0V DC socket located on the side
of the base station
Every time the thermo-hygro sensor is powered up (for exam-
ple after a change of batteries), a random security code is
transmitted and this code must be synchronized with the base
station to receive weather data.
When the base station is powered up, a short beep will sound
and all LCD segments will light up for about 5 seconds before
it enters into a 15 minute learning mode to learn the sensors
security code. After the learning mode (or by pressing the
MIN/MAX key at anytime), the base station will start the
DCF77 radio controlled time reception.
Note for DCF77 Radio Controlled Time:
The time and date display is based on the signal provided by
a highly accurate Caesium atomic clock operated by the
Physikalisch Technische Bundesamt in Braunschweig (Ger-
many). This radio-controlled clock does not only provide for
the weather station’s time and date display but also functions
as the time source for all of this weather station’s memory and
history values using time and date information.
LED backlight:
When using the power adaptor or under battery operation, the
LED backlight will switch on for 15 seconds when any key is
pressed.
6. Operation using cable connection or wireless
433MHz
Cable Connection:
Using this method of operation will provide interference free
transfer of the weather data from the sensors to the base
station. The data sending interval from the sensors to the
base station will also be more frequent compared to using
59

60
433MHz transmission and will result in higher power con-
sumption. Therefore batteries will have a shorter life span for
cable connection compared to using 433MHz.
To operate using cable connection, simply use the enclosed
10 meter cable and connect the thermo-hygro sensor to the
base station. Once the connection is detected, the base sta-
tion will automatically continue reading the data from the
sensor.
The user may at any time switch from cable connection to
using 433MHz (or vice versa) by simply disconnecting (or
connecting) the cable from the base station to the sensor.
When the base station detects no cable connection to the
sensors, the existing data reading interval is changed to the
new reading interval, i.e. using cable connection is every 8
seconds data reading interval or from 32 seconds - 128 sec-
onds intervals when using 433MHz (depending on wind
speed)
Using the AC adaptor to operate the base station will also
supply power to the sensor if the cable is connected to it.
Batteries used for 433MHz transmission may be left in the
sensor when using cable connection for power back-up in
case of AC power failure. A loss of power would desynchro-
nize the base station and the sensor and no weather data will
be received. To Synchronize the units so that the weather
data can be received, press and hold the PLUS(+) for 2 sec-
onds. However in general, batteries that will not be used for
long periods should be removed to avoid leakage.
Wireless 433MHz transmission:
Using 433MHz wireless transmission of weather data from the
sensor to the base station will provide users greater freedom
as to where units can be positioned without the need to be
restricted by cable.
Note:
If no outdoor weather data is displayed or the signal to the
sensors is lost during setting up, mounting, changing of batter-
ies to the sensor or plugging or unplugging cables, simply
press and hold the PLUS(+) key for 2 seconds and a short
beep will sound to synchronize the base station to sensors.

Without being synchronized, weather data will not be re-
ceived.

8. Function test:
Once the weather station is powered up, perform a function
test by checking that the weather data is received. To do this,
press the either DISPLAY, PRESSURE or WIND keys to
toggle through the relevant LCD sections:
1) Indoor temperature and humidity
2) Outdoor temperature and humidity
3) Outdoor wind chill
4) Dew point
5) Rainfall 24 hour
6) Rainfall 1hour
7) Rainfall Total
8) Relative and absolute pressure
9) Wind speed, wind direction and wind direction in degrees
If any readings cannot be received from the sensors, lines (- -
-) will be displayed in the respective weather sections of the
LCD. In this case, check that all cables are correctly inserted
into the correct sockets and press and hold the PLUS(+) key
for 2 seconds and a short beep will sound to synchronize the
62

base station to the sensors otherwise no weather data will be
received.
Some weather readings such as wind speed and direction
may not appear immediately on the LCD if the wind-fan or
vane of the wind sensor is moved. This is due to the set
reading time intervals for the wind readings. However the
current wind speed or direction will be displayed once the time
reading interval is reached. For rainfall, the interval readings
may take up to 2 minutes before the data is displayed on the
LCD.
9. Mounting
Important Note
Prior to drilling mounting holes and permanently affixing any of
the units, please ensure the following points are considered:
• Cable lengths of the units meet with your distance re-
quirements at the point of fixing
• Signals from the sensors can be received by the base
station at points of mounting
• Radio controlled time signal can be received at the point
of mounting
Base Station
With two foldable legs at the back of the unit, the base station
can be placed onto any flat surface or wall mounted at the
desired location by the hanging holes also at the back of the
unit. It is important to check that the 433MHz (if using wireless
connection) and the DCF77 radio controlled time signal can
be received before permanently mounting any of the units.
Should the base station not display the 433MHz weather data
from the sensors or the radio controlled time from the desired
location, then relocate the units. Once the signals are re-
ceived, the system can be affixed. Also if you have selected to
use cable connection, ensure that distances can reach all
desired locations before affixing any unit permanently
63

Mounting the Wind Sensor onto a mast
64
Firstly, check that the wind-fan and the wind-vane can rotate
freely before fixing the unit. For correct and accurate readings
it is important to mount the sensor so that the front (marked E)
is pointing in East-West direction. The wind sensor should
now be mounted using the screw provided onto a mast to
allow the wind to travel around the sensor unhindered from all
directions (ideal mast size should be from Ø16mm – Ø33mm).
Once the wind sensor is fixed onto the mast, connect the
cable to the corresponding thermo-hygro sensor socket so
that operating power supply can be received and data can be
transmitted to the base station.
Mounting the Rain Sensor
Wind-fan
Wind-vane Mast
Base portion
Funnel portion
For best results, the rain sensor should be securely mounted
onto a horizontal surface about 1 meter above the ground and
in an open area away from trees or other coverings where
rainfall may be reduced causing inaccurate readings.

When securing into place, check that rain excess will not
collect and store at the base of the unit but can flow out be-
tween the base and the mounting surface (test by pouring
clean water).
After mounting the rain sensor, connect the cable to the
thermo-hygro sensor at the corresponding socket so power
supply can be received and data be transmitted to the base
station
The rain sensor is now operable. For testing purposes, very
slowly pour a small amount of clean water into the rain sensor
funnel. The water will act as rainfall and will be received and
displayed at the base station after about 2 minutes delay i.e.
when the reading interval is reached (to clear this testing data
on the base station, refer to the section “MIN/MAX Mode”
below).
Mounting the thermo-hygro Sensor
Wall Bracket
Rain Cover
Main Unit
An ideal mounting place for the thermo-hygro sensor would be
the outer wall beneath the extension of a roof, as this will
protect the sensor from direct sunlight and other extreme
weather conditions.
To wall mount, use the 2 screws to affix the wall bracket to the
desired wall, plug in the thermo-hygro sensor to the bracket
and secure both parts by the use of the supplied screw and
ensure that the cables from the wind and rain sensors are
correctly plugged in otherwise data transmission errors could
occur.
65

10. Resetting & factory settings:
As previously mentioned, in the event of a power reset to the
sensor (for example a change of batteries), the base station
has to synchronize to the sensor again otherwise no weather
data will be received. To do this, simply press and hold the
PLUS(+) key for 2 seconds and a short beep will sound to
synchronize the base station to the sensor. When the units
are synchronized, the data will be received again and the
base station will return to normal operation mode.
Do not reset the power of the base station otherwise all 175
sets of recorded weather history data for transferring to the
PC will be lost (for full details of PC use, please see PC user
manual in the enclosed Heavy Weather CD-ROM).
However if you wish to make a full reset of the base station
and return to the original factory settings, simultaneously
press and hold the PRESSURE and WIND keys for about 5
seconds. The base station will beep once and the entire LCD
will light up for 5 seconds and go back to the original factory
settings. This process with clear all previous user defined
values and all weather history recordings.

11. Function Description of the Weather Station
After setting up, the following data will be displayed in different
sections on the LCD. If this is not the case please observe the
notes on “Interferences” below.
Time & Date (LCD Section 1)
If the DCF77 icon (icon 2) is ON and not flashing, it means
that the DCF77 radio-controlled time and date are has been
received. Press the PLUS(+) key to change the format of date
display between date/month/year, weekday/date/month,
seconds, alarm set time and time zone.
LCD Section 1:
Time, date, seconds,
time zone, weather
forecasting icons with
tendency arrows, air
pressure, and respec-
tive alarms sections
LCD Section 2:
Indoor and outdoor
temperature and rela-
tive humidity, wind chill,
dew point, rainfall, and
respective alarms
sections
LCD Section 3:
Wind direction, wind
speed, and respective
alarms sections
Weather forecasting (LCD Section 1)
The three weather icons Sunny, Cloudy and Rainy represent
the weather forecasting. There are also two weather tendency
indicators to show the air pressure tendency either side of the
weather icons.
68

Sunny RainyCloudy
Notes to hPa sensitivity setting for weather forecasting:
The hPa (Hekto-Pascal) pressure sensitivity can be set to suit
the user’s requirement for weather forecasting from 2 hPa to 4
hPa (see Basic Programming below). For areas that experi-
ence frequent changes in air pressure (which does not neces-
sarily reflect a change in the weather) requires a higher hPa
setting compared to an area where the air pressure is stag-
nant. For example if 3 hPa is selected, then there must be a
fall or rise in air pressure of at least 3 hPa before the weather
station will register this as a change in weather.
Air Pressure (LCD Section 1)
The air pressure reading is displayed here. Press the PRES-
SURE key to toggle between relative and absolute air pres-
sure displays.
Notes to Absolute and Relative Air Pressure:
Absolute air pressure provides the display of the true meas-
ured air pressure of the current time and location. This is not
programmable and the absolute air pressure range of the
weather station is from 300 hPa to 1099 hPa (standard air
pressure at an altitude of 9,100 meters is around 300 hPa).
Relative air pressure is the one value that is calculated back
to sea level from the local absolute air pressure and can thus
be taken as a reference for weather condition and weather
development for the entire country. It can be programmed to
represent your local surroundings. Since the relative air
pressure is also the one value given by various newspapers,
TV and radio broadcasting stations in their daily weather
forecasts for their respective locations, users can set the
relative air pressure of the weather station to this value to
represent readings your their area (see Basic Programming
Modes below).
69

70
Weather Data (LCD Section 2)
Indoor temperature and humidity are displayed simultaneously
in this section. Use the DISPLAY key to toggle through the
displays for other weather information:
- Outdoor temperature/humidity
- Outdoor wind chill
- Outdoor dew point
- Rainfall 24h
- Rainfall 1h
- Rainfall total.
Notes to Dewpoint and Windchill:
Air can at a certain temperature only carry a certain amount of
water (water vapor), which also increases and decreases with
temperature. If the air temperature decreases below the so
called dewpoint (saturation point), the excessive water vapor
will condense and fall out in form of dew, fog or rain. At a
temperature of e.g. 15°C and a relative humidity of 50% the
dewpoint will be about 5°C, at 80% humidity about 12°C. At a
relative humidity of 100% saturation is reached, i.e. the dew-
point is 15°C. At a dewpoint below freezing the fallout will
become frost or snow.
Windchill has been introduced for battle planning during World
War II. It represents not the real measured but the one tem-
perature a person feels in open area under the influence of
wind and cold. Windchill is laid out in tables for various tem-
peratures and wind speeds. At an outdoor temperature of e.g.
8°C and calm winds a person moving at a speed of 6 m/s will
already feel a windchill temperature of 0°C.
Wind Data (LCD Section 3)
The current wind direction will be displayed on the LCD com-
pass on the wind section. Press the WIND key to toggle be-
tween wind direction as numerical (e.g. 225°) and abbreviated
characters (e.g. SW) as well as numerical wind speed display
inside the compass circle.
