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
features and functions so that you can enjoy the safe and correct opera
tion of this unique product.
2. Intended se
Weather Station
The base station measures the indoor environment of its surrounding
area and receives weather data from the following three outdoor sen
sors:
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 sen
sor 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 connection.
Using the enclosed 2 meter computer cable and CD ROM, you can
install the Heavy Weather software to your PC and upload all the re
ceived 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 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.

tive humidity. It also collects the readings from the rain and wind sen

46
sors 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. Oper
ating 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 operation of using wireless
433MHz transmission or cable connection between the base station and
the sensors and setting up for both methods is as follows:
Base Station:

49
Setting up using batteries:
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 sta
tion)
2) Connect the attached cables of wind and rain sensors to the corre
sponding 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 com
partment and close the battery cover

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 example 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 Tech
nische Bundesamt in Braunschweig (Germany). This radio controlled
clock does not only provide for the weather station’s time and date dis
play 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 send
ing interval from the sensors to the base station will also be more fre
quent compared to using 433MHz transmission and will result in higher
power consumption. 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

51
the connection is detected, the base station 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 de
tects no cable connection to the sensors, the existing data reading in
terval 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 de
synchronize 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 seconds. However in gen
eral, 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 batteries 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 sta
tion to sensors. Without being synchronized, weather data will not be
received.

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 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 sen
sor 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 read
ings 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 requirements 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 mount
ing

54
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 loca
tion, then relocate the units. Once the signals are received, the system
can be affixed. Also if you have selected to use cable connection, en
sure that distances can reach all desired locations before affixing any
unit permanently
Mounting the Wind Sensor onto a mast
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 sen
sor 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.
Wind-fan
Wind-vane
Mast

55
Mounting the Rain Sensor
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 caus
ing 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 between 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).
Base portion
Funnel portion

56
Mounting the thermo-hygro Sensor
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.
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 “Inter-
ferences” 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.
Weather forecasting (LCD Section 2)
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.
LCD Section 1:
Time, date, seconds, time zone
LCD Section 3

tendency arrows, air pressure,
and respective alarms sections

59
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 experience frequent changes in
air pressure (which does not necessarily reflect a change in the
weather) requires a higher hPa setting compared to an area where the
air pressure is stagnant. 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 2)
The air pressure reading is displayed here. Press the PRESSURE key
to toggle between relative and absolute air pressure displays.
Notes to Absolute and Relative Air Pressure:
Absolute air pressure provides the display of the true measured 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 refer
ence 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).
Weather Data (LCD Section 3)
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.

60
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 dewpoint 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 temperature a person
feels in open area under the influence of wind and cold. Windchill is laid
out in tables for various temperatures 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 4)
The current wind direction will be displayed on the LCD compass on the
wind section. Press the WIND key to toggle between wind direction as
numerical (e.g. 225°) and abbreviated characters (e.g. SW) as well as
numerical wind speed display inside the compass circle.
