1) Check that the wind-vane and fan of the wind sensor can freely rotate by moving the vane gently and also blowing into
the fan to emulate wind speed and direction

2) Holding the rain sensor in both hands with the longest side facin g you , tilt the unit fr o m side to side and hear the rain
counter flip which emulates rainfall

3) The base station will start to receive the 433MHz data transmitted from the sensors. Data such as rainfall will not be
updated as regularly as the outdoor temperature since it does not rain constantly all the time. Therefore these readings
may take up to two minutes before being shown on the LCD.

4) Now using the DISPLAY key on the base station, toggle between different weather modes on the LCD to check that the
weather readings can be received for the relevant sections, for example outdoor temperature and humidity and etc.

Note: Should any outdoor data not be received from the sensors (when “- - -“ is displayed), check all cables are correctly
inserted and/ or the batteries or AC cord are plugged in, press and hold the PLUS(+) key for 2 seconds to hear a beep and
the base station will synchronize to the sensors transmitting signal. Wind speeds that read zero does not mean reception
failure, it simply means that there was no wind at the time of reading the data.

Mounting the units:
Users must take their surroundings into c onsider ation befor e decidin g which met hod is best sui ted for the m. Connect ion by
cable is advantageous in that data from the sensors to the base station is interference free. Using 433MHz wireless
transmission gives users little restric tion on p laceme nt as th at all un its ca n be p ositione d virtu ally an ywhere to within a 100 ft
radius of the base station. You mus t decide which me thod is best suited to you. For cable connect ing, please ensure that
the 10 meters cable included in this se t m ee ts with your dis tance requirements (see accessories in the main user manual for
adding extension cables).

To change from 433MHz to cable connection (o r vice versa) simp ly connec t (or d i sco nnec t ) the 32f t cab l e from the base
station to the sensor. The base station will automatically detect the connection and read the weather data. If the data
cannot be received then press and hold the PLUS(+) key for 2 seconds to synchronize the base station with the sensor.

Important: Ensure all signals including the radio controlled time can be received and/or all cable distances meet with your
requirements at the point of fixing particularly before you start drilling any mounting holes.

Wind sensor

Secure the main unit to the shaft of the mast holder using the single screw provided with the front of the sensor (marked E)
facing in the East-West direction other wise wind direction will not be accurate. Now fix the entire unit to a suitable ma st
using the 2 two U-bolts, 4 washers and nuts found in this set.

Note: For best results mount the wind sensor onto a mast to all ow the wind to freely trav el from all directions t o enable an
accurate reading (ideal mast size s hould be from Ø6 .3” – Ø1.3”). Ens ure that the 10 meter cable of the wind sensor me ets
your distance requirements.

Rain sensor

The rain sensor should be mounted h orizontally about 2-3ft off from the gr ound in an open area away from trees or o ther
coverings to allow rain to fall naturally for an accurate reading.

Note: For best results ensure the base is horizontal to allow maximum drainage of any collected rain
Thermo-hygro Sensor

To wall mount the thermo-hygro sensor , fix the wall holder onto the desire d wall (2 screws are supplied), plug the sens or
firmly into the wall holder and then carefully replace the rain cover back over the thermo-hygro sensor.

Note: After mounting the units, should the weather data not be received then press and hold the PLUS(+ ) key for 2 seconds
to synchronize the base station with the sensor.

1. Introduction

Thank you for purchasing this Professional Remote Weather Stat ion.
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 thorough ly to fully underst and 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 fo llowing three out door 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 t he wind
and rain sensors are connected to the ther mo-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 100ft in open space) or by cable
connection.

Using the enclosed 6.5ft computer cabl e 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 chart s onto your spreads heets
(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.

sensors before transmitting the data to the base station b y wirel ess
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 thermo­hygro 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.

5. Setting up

r

r

First, choose to use the adaptor (included in this set) or batter­ies for operation. Both these methods allow for operation 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:

Socket for
Adaptor

Socket for
Thermo-Hygro
Sensor

PC COM
Port

Battery compartment

Setting up using batteries:

Thermo-Hygro Senso

Sensor sockets

Battery
Compartment

Battery Cove

Sensor sockets

Important: To avoid operating problems, please take note of bat-

tery polarity if inserting any batteries

1) Pull away the rain cover of the thermo-hygro sensor to reveal th e
three sockets (for the wind sensor, rain sens or 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 belo w
the three sockets and insert 2 x AA, IEC LR6, 1.5V batter ies and
close the cover

4) Open the bas e station’s battery cover located at the back of the
unit and insert 3 x AA, IEC LR6, 1.5V batteries i nto the battery
compartment 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 o utlet and
power up the base station by inserting the adaptor jack into the
DC 6.0V socket located on the side of the base station

Every time the thermo-hygro sensor is powered up (f or example after
a change of batteries), a random security code is transmitted an d 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 ab out 5 seconds before it enters into a
15 minute learning mode to learn the sensors security code. Af ter the
learning mode (or by pressing the MIN/MAX ke y at an ytime), the base
station will start the WWVB radio controlled time reception.

Note for WWVB Radio Controlled Time:

The time and date display is based on the signal provided by the
highly accurate government operated atomic clock in Ft. Collins,
Colorado. This radio-controlled clock does not only provide for the
weather station’s time and date display but also functions as the time
and date source for all of this weather station’s memory and hist ory
values using time and date information.

LCD backlight:

When using the power adaptor, the LCD backlight is switched on
continuously. Under battery operation, the LCD backlight is switched
on for 15 seconds intervals 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 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 enclose d 32ft
cable and connect the thermo-hygro sensor to the base station. Once
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
detects no cable connection to the sensors the base station will auto­matically change to using 433 MHz for reception of the weather data
from the sensors.
The data receiving intervals are as follows:

-Using cable connection data is updated every 8 seconds.

-Using wireless 433 MHz data is updated from 16 to 128 second
intervals depending on wind speed and rain activity.

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 desynchronize 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 (+) key for 2
seconds. 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 b y cable.

Note:

If no outdoor weather data is displayed or the sign al 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 station 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 b y
checking that the weather data is received. To do this, press the
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/or check the batteries in the outdoor t hermo/hygro sen­sor and press and hold the PLUS (+) key for 2 seco nds and a short
beep will sound to synchronize the base station to t he 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 t he
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 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
mounting

NOTE: The WWVB receiver is located in the base station.

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 un it. It is important t o check
that the 433MHz (if using wireless connection) and the WWVB 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 re­ceived, the system can be affixed. Also if you have sele cted to use
cable connection, ensure that distances can reach all desired loca­tions before affixing any unit permanent ly

NOTE: For reception of WWVB time/date signal, do not mount
the base station closer than 5 feet from a computer, florescent
lights or other electrical appliances. Do not mount the base
station on a wall that has metal heat/AC ductwork in the wall
behind the base station. For best WWVB reception place the
base station near a window facing Colorado. WWVB reception
will be obtained easiest in the nighttime hours when the
WWVB signal is strongest.

Mounting the Wind Sensor onto a mast

Wind-vane

Wind-fan

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 t o travel around the
sensor unhindered from all directions (ideal mast size should be from
Ø.63” – Ø1.3”).

Once the wind sensor is fixed onto the mast, connect the cable to th e
corresponding thermo-hygro sensor socket so that operating power
supply can be received and data can be tra nsmitted to the base sta­tion.

Mounting the Rain Sensor

Base portion

For accurate results, the rain sensor should be securely mounted
onto a horizontal surface about 2-3ft 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 between the base an d
the mounting surface (test by pouring clean water).

After mounting the rain sensor, connect the cable t o the ther mo-hygro
sensor at the corresponding socket so power supply can be receiv ed
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 fu nnel. The
water will act as rainfall and will be received and displayed at the
base station after about 2 minutes d ela y i.e. when t he read ing interval
is reached (to clear this testing data on t he base station, refer to the
section “MIN/MAX Mode” below).

Mounting the thermo-hygro Sensor

Rain Cover

Wall Bracket

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 condit ions.

To wall mount, use the 2 screws to affix the wall bracket to the de­sired wall, plug in the thermo-hygro sensor to the brack et and secure
both parts by the use of the supplied scre w and ensure that the ca­bles from the wind and rain sensors are correctl y plugged in other­wise data transmission errors could occur.

NOTE: For best 433 MHz reception mount the thermo-hygro sen­sor on an outside wall near the location of th e base station.

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 st ation has to synchro­nize to the sensor again otherwise no weat her data will be received.
To do this, simply press and hold the PLUS (+) ke y for 2 seconds and
a short beep will sound to synchronize the base station to the s ensor.
When the units are synchronized, the dat a will be received ag ain and
the base station will return to normal operation mode.

Do not remove batteries or unplug the AC adaptor of the base station
otherwise all 175 sets of recorde d weather history data for transfer­ring to the PC will be lost (for full deta ils 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 retur n
to the original factory settings, simultaneously press and hold the
PRESSURE and WIND keys for about 5 seconds. The b ase station
will beep once and the entire LCD will light up for 5 seconds and go
back to the original factory sett ings. This process with cle ar all previ­ous user defined values and all weather history recordings.

user’s requirement for weather forecasting from 6 inHg, 9 inHg to 12
inHg (see Basic Programming below). For areas that exp erience
frequent changes in air pressure (which does not necessarily reflect a
change in the weather) requires a higher inHg setting compared t o an
area where the air pressure is stagnant. For example if 6 inHg is
selected, then there must be a fall or rise in air pressure of at least 6
inHg 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 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

8.85 inHg to 32.45 inHg (standard air pressure at an altit ude of
30,000ft is around 8.85 inHg).

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 l ocal 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 2)

Indoor temperature and humidity are displayed simu ltaneously in this
section. Use the DISPLAY key to toggle through the displays f or 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 cert ain amount of water
(water vapor), which also increases and decreases with temperat ure.
If the air temperature decreases below the dewpoint (saturation
point), the excessive water vapor will condense and fall ou t in form of
dew, fog or rain. At a temperature of e.g. 5 9°F and a relativ e humidity
of 50% the dewpoint will be about 41°F, at 80% humidity about

53.6°F. At a relative humidity of 100% satur ation is reached, i.e. the
dewpoint is 59°F. At a dewpoint below freezing the fallout will become
frost or snow.

Windchill has been introduced for battle planning during World War I I.
It represents not the real measured but the temperature a person
feels in open area under the influence of wind and col d. Windchill is
laid out in tables for various temperatures and wind speeds. At an
outdoor temperature of e.g. 46.4°F and calm winds a per son moving
at a speed of 13 mph will already feel a windchill temperature of 32°F.

Wind Data (LCD Section 3)

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.

The base station will continue to scan for the radio controlled time
signal from 12am-6 am (1am-6pm summer time) each day despite it
being manually set. During reception attempts t he WWVB tower icon
will flash.

• If reception has been unsuccessful, then the WWVB to wer
icon will not appear but reception will still b e attempted the
following hour within the time frame

•

If reception has been successful, the received time a nd date
will overwrite the manually set time and date and n o further
reception is attempted until the following day

14. MIN/MAX Programming Modes
MIN/MAX display Mode

The MIN/MAX Mode provides the user with information about the
MIN/MAX values of all weather data together with the t ime and date
at which these values were recorded.

Entering each MIN/MAX mode

In the normal display mode for e.g. the indoor temper ature and hu­midity, press MIN/MAX key to togg le the display between the maxi­mum, minimum and current records. While the maximum or minimum
values are shown press the DISPLAY key on ce to show the time an d
date that value was received. Now press th e MIN/MAX key to toggle
from the minimum and maximum readings and the time and dates the
records were received are also shown. Still in the MIN/MAX mode
(where the time and date for a value are sho wn), press the DISPLAY
key to move through each respective unit as follows:

• Indoor temperature (max or min with time and date)

• Indoor humidity (max or min with time and date)

• Outdoor temperature (max or min with time and date)

• Outdoor humidity (max or min with time and date)

• Outdoor wind chill (max or min with time and date)

• Outdoor dew point (max or min with time and date)

• Rainfall 24 hours (max or min with time and date)

• Rainfall 1 hour (max or min with time and date)

•

Rainfall total (max only with time and date)

When in any of the above modes, press the MIN/MAX key to t oggle
between the maximum or minimum values of those records and their
respective time and dates will also be shown.

For the wind and pressure minimum and maximum readings, the
same would apply except that the WIND or PRESSURE keys would
be used instead of the DISPLAY KEY.

Exiting the MIN/MAX modes

If the maximum and minimum modes with times and dates are dis­played, press the PLUS (+) key twice to return the normal display
mode.

Resetting the MIN/MAX records

While in the minimum or maximum mode, the time and d ates are also
displayed along with the recorded values. If the MINUS (-) key is
pressed while any of these values ar e displayed, that particular mini­mum or maximum record will be reset to current reading together with
the current time and date with the exception of the following:
 The first case is Rainfall Total, which has neith er maximum nor

minimum records since it will show only the total rainfall. Pressing
the MINUS (-) key will reset the rainfall total value to zero and the
time recording to current time.

 The second case is Rainfall 24h or 1h, which records maximum

rain count only for these respective times. Pressing the MINUS (­) key in either of these two modes will reset the rain c ount to the
current rain count and time and date.



The third case is wind speed, which will only reset t he recorded
time to current time when the MINUS (-) key is pressed.

alarm setting modes.

When a set weather alarm condition has been activated, that particu­lar alarm will sound and flash for approximately 2 minutes but will
continue to flash until weather conditions have become more steady.

Weather Alarms

The weather alarms are settable for when certain weather conditions
are met according to the users requirements. For example , the user
can set the thresholds for the outdoor temperature to +86°F (high)
and 14°F (low), while only enabling the high alarm and dis abling the
low alarm (i.e. temperatures <-14°F won’t trigger alarm, but tempera­tures >+86°F will).

Alarm setting Minimum Maximum

Storm threshold 0.09 inHg 0.27 inHg
Relative Air Pressure 27.10 inHg 31.89 inHg
Outdoor Temperature -21.8°F +157.8°F

Indoor Temperature 14.1°F. No alarm will

sound if the minimum
indoor temperature
alarm is set below this

value.
Humidity (all) 20% RH 95% RH
Rainfall 24h 0.0 inch 39.37 inch
Rainfall 1h 0.0 inch 39.37 inch
Wind 0.0 mph 111.8 mph

+139.8°F

Hysteresis

To compensate for fluctuation of the measured data, which may
cause the weather alarm to sound constantl y if the measure d reading
is close to user set level, a hysteresis function has be en implemente d
for each weather alarm. For example, if the hig h temperature alarm is
set to +77°F and the current value moves to +78°F, the al arm will be
activated (if it has been enabled). Now when the temperature drops to
+76°F or below and thereafter agai n increases to beyond +77°F, the
data will be blinking, but no alarm will be activated. It has to drop t o
below +75.2°F (with a pre-set hysteresis of 1.8°F) so that the alarm
can be produced again. Hysteresis values for the various weather
data types are given in the following table:

Weather data Hysteresis

Temperature 1.8°F
Humidity 3% RH
Air pressure 0.0295 inHg
Rainfall 24h 0.1968 inch
Rainfall 1h 0.01968 inch
Wind 3.1 mph

16. Auto memory for stored values

The base station has a memory back up system, which is used to
memorize user-defined settings for when the batt eries ar e chan ged or
if a power failure occurs. User defined units a re aut om atical l y upd ated
each time these are changed. The base station will memorize the
following user defined units:

• Time zone

• 12/24h time display mode

• Unit settings (temperature, pressure, rainfall, wind)

• Air pressure off s et for calculation of relative air pressure

• Weather picture threshold

• Storm warning threshold

• LCD contrast

• Alarm time

• Weather Alarm thresholds

• State of alarms (enabled/disabled)

• Rainfall total value and reset time/date

17. Accessories: adding cable extensions

For your convenience, additional telephone cables to increase the
connection distance between each of the units may be purchased
from any reputable hardware store. Simply add these to the current
cables to extend your cable connection distan ce.

Telephone Extension Cables

When securing the cables during mounting, ensure that base station
can receive the weather data since increasing the cables lengt hs may
also increase levels of interference and result with reception difficul­ties. Interference levels will greatl y depend on the surrounding area
for example setting up on or near metal piping may considerably
reduce reception.

For best results, do not to add more than 32ft of extension cabl e from
item to item onto the existing cable lengths as this may reduce recep­tion levels. Again, reception and interferen ce levels will greatly de­pend on the surrounding environment at your point of mounting.

Note:

It is important to keep all the connecte d extension heads away from
rain, moisture and other extreme weather conditi ons as exposure can
cause short circuits and damage to this item.

18. Changing batteries:
Battery change only in the thermo-hygro-sensor:

1. Open the battery cover

2. Remove the old batteries and insert with new ones of the rec­ommended type and replace the cover

Once the sensor is powered up, press and hold the PLUS (+) key for
approx. 2 seconds in the normal display mode, the b ase station will
sound a short beep and synchronize to the sensor otherwise no
weather data will be received.

Battery change only in the base station:

1. Connect power adaptor to base station and p ower outlet.

2. Open the battery cover located at the back of the base station.

3. Remove the old batteries, insert with new ones of the recom­mended type and replace the cover

This method of battery replacement will result in no loss of MI N/MAX
and history data. However in case of poss ible po wer fail ure, the bas e
station will lose the MIX/MAX and al l weath er data r ecordings a nd will
need to be synchronized to the sensors again by pressing the PLUS
(+) key for 2 seconds.

Note:

When batteries require replacement for the base station, the low
battery indicator will light up on the LCD.

Please participate in the preservation of the en vironment
by properly disposing of all used-up batteries and accu­mulators at designated disposal points. Never dispose of
batteries in a fire as this may cause explo sion, risk o f fire
or leakage of dangerous chemicals and fu mes

receiver.

Quite frequently interferences are only of a temporary nature and may
be easily overcome. If there are wireless headsets, remot e babysit­ters or other devices working on 433MHz in your house or in the vicin­ity, their switch-on time is mostly limited. Furthermore most of these
devices allow the change to an interference-free frequency. Such
measures will effectively overcome interferences.

20. Transmission Range

The transmission distance from the thermo- hygro sensor to the base
station in open space under optimum conditions is 100ft. Although
the signal transmission may travel though solid surfaces or objects,
the following points should be avoided if possible:

- High frequency interferences of any kind.

- High densities of trees.

- Broadband interferences in municipal areas can reach levels

reducing the signal/noise ratio over the entire frequency band,
thus also reducing the transmission distance.

- Devices working close by (example a neighbor’s house) may

also influence reception.

- Poorly shielded PCs can cause interferences t hat will reduce or

in some cases stop reception

- The transmitter and receiver should not be mounted on metal

surfaces as this will reduce transmission range.

21. Cleaning and Maintenance

- Clean the housing and screen of the base station only with a soft

damp cloth. Do not use abrasives or solvents.

- Ensure that the rain sensor does not collect leaves or other dirt

by checking the funnel for blockages every no w and then. Also
clean the seesaw of the sensor with a damp cloth and check by
lightly tapping with your finger t hat it can move freely from side
to side.

- Do not clean the funnel with the bottom half of the rain sensor

attached nor the bottom part itself under running water. This
may bear the danger of water entering the unit’s inn er parts and
cause damages.

- Do not immerse the base station in water.

- Should there be damage to this product, please do not att empt

to make any repairs. Please take this unit t o a qualified techni­cian. Opening or improper handling of the units will invalidate
any guarantee.

1.0 General Information

This weather station is a high quality, easy to use weather monitoring system that reads, displays and records
the weather data from three external sensors. One sensor will take data for temperature and humidity; one for
wind and the other for rainfall measurement. Operation of this unit can either be by cable connection or by
wireless 433MHz to the base station.

In stalling the “Heavy Weather” program on this CD-ROM will display all the weather data from the base
station received from the three external sensors onto your PC. For operation, simply use the PC cable
supplied and connect the base station to the PC using the desired COM port on your PC (see Installing the

4.0 Installing PC Software below).

2.0 System Re quirements

To install the “Heavy Weather” software onto your PC, the minimum system requirement is:

• Operating system: Windows 98 or above

• Processor: Pentium 166 MHz or above processor

• RAM: 32MB of Ram or above

• Hard disk: 20MB free space

• CD-ROM drive

3.0 Basic settings of the base station and sensors:

This section describes the set up and settings of the weather station and sensors necessary for operation with
the Heavy Weather software. For a complete and detailed explanation of the weather station, please refer to

the main instruction manual enclosed with the purchase of this set.

3.1 Base station (receiver)

The base station reads the indoor and outdoor weather the data from the thermo-hygro, wind and rain
sensors. Together with the radio controlled time, all the data is displayed on the large LCD with LED back­light.

• The base station can be battery operated using 3 x AA, IEC LR6, 1.5V batteries or with the AC/DC
adapter provided.

3.2 Thermo-hygro sensor

The thermo-hygro sensor measures the temperature and the humidity of it’s surrounding outdoor environment
and at the same time, collects the data from the rain and wind sensors before transmitting all the weather data
to the base station by wireless 433MHz or by a cable connection.

• Using wireless 433MHz, the thermo-hygro sensor requires 2 x AA, IEC, LR6, 1.5V batteries.

• Using cable connection from the base station to the sensors, power is supplied by either the AC/DC

power adaptor (included) or 2 x AA, IEC, LR6, 1.5V batteries.

3.3 Wind sensor

The wind sensor collects both the wind speed and wind direction data at the point of mounting and sends this
to the thermo-hygro sensor for transmitting to the base station.

• Install the wind sensor onto an outdoor mast in open space since it is important for the wind sensor to be
fully exposed to allow for accurate wind measurements from unhindered wind directions

• For operation, it is necessary to connect the wind sensor to the thermo-hygro sensor for transmission of
data and also for operating power.

3.4 Rain sen sor

The rain sensor collects rainfall data and displays this on the base station.

• It is recommended to install the rain sensor on a flat surface securely in the open and free from any
obstructions (i.e. falling leaves, roof coverings and etc.)

• For operation, it is necessary to connect the rain sensor to the thermo-hygro sensor for transmission of
data and also for operating power.

4.0 Installing the PC software

AC/DC jack

Thermo-hygro jack

PC COM port cable jack

First, the weather station and the outdoor sensors should all be connected for operation and checked that it is
functioning correctly. After checking, install the “Heavy Weather” PC software as follows:

1) Switch on your PC and insert the Heavy Weather CD-ROM into the ROM drive and the program will

begin to auto install

2) The “Heavy Weather Installation” window will now open so the user can change the directory or

confirm the directory automatically set by the installation process (directory will be used for data
saving from the weather station)

3) Click the Finish button to confirm and the software will be installed

4) After successfully installing the software, the OK prompt appears for successful installation, click the

OK button to complete the process

5) The Heavy Weather directory is opened onto the screen, click to open the “Heavy Weather” icon to

run the program or open the program from the shortcut created your desktop

6) Once the Heavy Weather program is open, click the Setup button at the bottom right of the window to

select the COM port used for connection between the PC and base station (as shown below) and
press the OK button.

7) Now using the 6.5ft computer cable (included), connect the base station to the PC COM port. The

program will automatically detect the connection between the base station and the PC and will display
the weather data in the appropriate boxes.

Note: In the event the auto-install did not start, double click the set.exe file found in the root directory of the
CD-ROM to start the installation of the Heavy Weather software

5.0 Features and displayed weather information

5.1 Weather icons

The three weather icons can appear in the following combinations, provide a weather forecast upon reading of
any significant changes in air pressure:

Sunny Cloudy with sunny intervals Rainy

For every sudden or significant change in air pressure, the weather icons will update accordingly to represent
the change in weather. If the icons do not change, then it means either the air pressure has not changed or
the change has been too slow for to register a reading. However, if the icon displayed is a sun or raining
cloud, there will be no change of icon if the weather gets any better (with sunny icon) or worse (with rainy
icon) since the icons are already at their extreme points.

The icons displayed forecasts the weather in to terms of getting better or worse and not necessarily sunny or
rainy as each icon may indicate. For example, if the current weather is cloudy and the rainy icon is displayed,
it does not mean that forecast is not accurate because it is not raining, it means that the air pressure has
dropped and the weather is expected to get worse but not necessarily rain.

Note: After setting up, readings for weather forecasts should be discarded for the next 12-24 hours.

This will allow sufficient time for the unit to operate at a constant altitude and therefore result
in a more accurate forecast.

5.2 Storm Warning

The “lightening” icon next to the weather icon will appear when the storm alarm has been reached to indicate
a possible storm according to the user settable air pressure values set in the base station (see storm warning
alarm setting below). For storm warning air pressure sensitivity setting on the base, please refer the main
instruction manual.

Storm warning icon

5.3 Weather ten d ency indicato r

The weather tendency indicator arrow is located below the weather symbols. It indicates the air pressure
development and provides a forecast of the weather to be expected by the decreasing or increasing air
pressure. With the tendency arrow pointing upwards, it means that the air pressure is increasing and the
weather is expected to improve but if the tendency arrow is pointing downwards, the air pressure is
decreasing and the weather is expected to become worse.

5.4 Relative/Absolute Pressure

Relative air pressure is calculated at sea level from the local absolute air pressure and is thus valid as a
reference for weather conditions and weather developments. For example an absolute air pressure of 28.40
inHg in a city at an approximate altitude of 1500ft above sea level corresponds to a relative air pressure of

29.91 inHg at sea level. The relative unit pressure can be displayed in inHg or hPa

The recorded minimum and maximum pressure values within a period are also displayed along with the
corresponding dates and times and are automatically updated when a new minimum or maximum values are
reached.

5.5 Indoor and Outdoor Temperature/Humidity

The weather data recorded by the thermo-hygro sensor (for outdoor data transmission) and base station (for
indoor data) is displayed accordingly to the temperature, humidity section on the screen numerically and
graphically (for temperature data only)

The recorded minimum and maximum temperature and humidity values within a period are also displayed
along with the corresponding dates and times and are automatically updated when a new minimum or
maximum values are reached.

5.6 Dew point

Dew point occurs when the temperature and humidity is at such level that the humidity becomes a liquid on a
surface. The dew point data is displayed with current, minimum and maximum information.

The recorded minimum and maximum dew point values within a period are also displayed along with the
corresponding dates and times and are automatically updated when a new minimum or maximum values are
reached.

5.7 Wind chi ll

The wind chill data recorded by the wind sensor is displayed with current temperature, minimum and
maximum temperature recording.

The recorded minimum and maximum wind chill values within a period are also displayed along with the
corresponding dates and times and are automatically updated when a new minimum or maximum values are
reached.

5.8 Wind speed and direction

The wind data recorded by the wind sensor are received and displayed on the base station and heavy
weather program. The wind direction data is simply indicated by letters (for example N=North, NE=North East,
E, SE and etc.) or in degrees.

The wind speed unit is user selectable to display the wind speed in km/h, mph, meters-per-second and knots.
The bft (Beaufort scale) at the top of the wind section displays the velocity of each wind measurement in the
form of a bar for easy reference.

The recorded minimum and maximum wind speed values within a period are also displayed along with the
corresponding dates and times and are automatically updated when a new minimum or maximum values are
reached.

5.9 Rainfall

Three sets of rain data are recorded by base station and displayed on the on the base station and heavy
weather program as total rain, rain in the last 24 hours and rain in the last 1 hour. The information is displayed
numerically and graphically for easy reference. The scale in the total rainfall column will automatically
increase should the rainfall surpass the initial scale maximum displayed.

The recorded maximum rainfall value for 24 hour and 1 hour within a period is also displayed along with the
corresponding date and time and is automatically updated when a new maximum value is reached.

5.10 Weathe r History

Here the Heavy Weather program automatically records all the weather data from the current period onwards
to form a history of the weather events. The recording interval can be set from 1 minute to up to 60 hours in
the history section (default setting 1 hour) together with the option of recording a next set of data. The next
set of data option can be used for example if the user set the initial recording interval to every 1 hour and
required the next set of data for in 5 minutes time, the program would then initiate recording of the weather
data in 5 minutes before reverting to the previous setting of 1 hour. However based on the previously given
example, due to the mass communication of weather data and high frequency transmission from the sensors
to the base station to the PC and back again, it is possible that the next set of data recording i.e. 5 minute
interval will be missed and will not in fact be executed in exactly 5 minutes time as will be seen from the
history file.

From the main Heavy Weather window, the history section will show the file name used to save the weather
data together with the date and time and the total number of sets of data recorded. Each set of data consists
of pressure, indoor temperature, indoor humidity, outdoor temperature, outdoor humidity, dew point, wind chill,
wind speed, wind direction, total rain, time and date. The user can also select to record a new history file at
anytime by changing the history file or revert to any saved history file that had been previously saved. The
initial history file name is history.dat. If a previously saved history file is used again, the current recording
interval will be regarded as the latest setting and all new data will be recorded into that file (see 8.0 Settings
below for working detail). The history file can be displayed in a window parallel in running to the Heavy
Weather program. If desired the saved files can be saved as text files and opened in other formats.

Once the PC is switched off, connection to the base station will be lost but the base station will record all
weather events for up to 175 records in it’s memory bank according the interval set from the PC at the time of
power off. For example if the user set a history recording interval of 5 minutes, then the base station will store
all the weather data from 5 minute intervals for up to 175 sets of data until the Heavy Weather program is
used again. However there are no limitations for the number of history files saved onto the PC providing there
is sufficient space available on the hard disk.

Regardless of the interval setting on the software for reading data from the base station onto your PC, when
the base station has stored the maximum 175 sets of weather data into it's memory, new sets of data received
at the set interval will begin overwriting the oldest records on the base station and it is important to upload the
data to your PC before it gets lost. For example if the interval is set to take hourly readings, then the base
station will take 175 hourly readings which works out to a little over 7 days meaning that users have this
length of time to upload the data to their PC's as to not lose any data.

6.0 Using th e Heavy Weathe r software

6.1 Activating the weather softwar e

Once the weather station is connected to the PC, run the “Heavy Weather” program and it will automatically
detect the connection to the base station and start transferring the weather data from on the PC. All the
weather data; wind; rain; relative pressure; indoor and outdoor temperature/humidity; dew point and wind chill
will almost be simultaneously received and displayed in the relevant sections of the Heavy Weather program.

During High Frequency Reception (reception of data from the outdoor sensors to the base station), the HF
icon on bottom right hand corner of the Heavy Weather window will flash in red to indicate that high frequency
reception is taking place between the sensors and the base station and the received data will soon be
received and displayed by the Heavy Weather program.

and press the clear button.

8.22 Weather Alarm Notes:

To compensate for fluctuation of the weather data, which may cause the weather alarms to sound constantly if
the received data from the sensors is close to user set level, a hysteresis function has been implemented for
each weather alarm. For example, if the temperature high alarm is set to +77°F and the current temperature
value moves to +78°F, the alarm will be activated. When the temperature drops to +76°F or below and
thereafter again increases to beyond +77°F, the alarm bell icon will blink, but no alarm will be sounded. The
temperature has to drop to below +75.2°F (with a pre-set hysteresis of 1.8°F) so that the alarm can be
produced. This function will compensates for the need of constant and unnecessary alarm sounds

Hysteresis values created are given in the following table:

Condition Hysteresis

Temperature
Humidity 3% RH

Air pressure
Rainfall 24h
Rainfall 1h
Wind

1.8ºF

0.0295 inHg

Important!

If any alarm has been programmed through the Heavy Weather program to the base station, the alarm status
will remain in the PC if there is no connection between the base station and the PC or if the base station did
not read the alarm setting before the PC is switched off.

In any power reset, for example a change of batteries, the base station will not save any alarm status into its
memory bank. All previously set data will be lost and the alarm status is cancelled for both the receiver and
PC since the Heavy Weather program will read new data from the base receiver.

12.0 Operating Range

Under optimum conditions in an open field a range of up to 82ft wireless transmission is possible, i.e. when
there is ‘visual’ contact between the sensors and base station. Walls and reinforced concrete constructions
can be passed through, but they do reduce the operating distance accordingly. A reduced operating range
may be due to the following reasons:

• High frequency interference from other sources.

• Buildings of all types and trees.

• Especially in the case of the wind sensor, metal roofs or roof insulation with foil sealed glass wool can

reduce the range.

• Transmitter and receiver clearance from conductive surfaces or objects that give radiation
characteristic and thus the range

• Neighboring using units operating on the same frequencies may affect the receiver.

• Poorly screened PCs may affect the receiver and reduce the reception ranges

13.0 Understanding Displayed Weather Data

When the transfer of the updated weather information occurs or the user has entered new settings (for
example setting high and low alarms) from the base station to the PC, there may be a very small time delay
until the data is updated to the PC. For this reason new data may not be displayed immediately onto your PC
even though it has been changed on the base station. The base station experiences this same short time
delay when new data settings are entered from the PC before the base station can recognize and shows this
on the LCD.

During the high frequency reception periods from the outdoor sensors to the base station, any data transfer
from the base station to the PC or vice versa will experience a longer time delay due to the mass amounts of
weather information being simultaneously received and transmitted from the sensors to the base station which
is why any data changes made by the user may not register immediately. Time delay of data reception and
transfer is normal so when newly entered data does not immediately register from the base station to the PC
or vice versa it is due to the frequent communication between all the sensors and base station and the PC.

Furthermore, due the constant weather information updating from the sensors to the base station, the data
displayed on the PC may not be the updated information received by the base station since the data may not
have been transferred to the PC yet. Therefore users may experience different sets of data shown on the
base station and the Heavy Weather program until such time the data is updated to the PC. The Heavy

Weather program only displays the information received by the base station and does not receive any data
directly from the sensors.

the set up menu on the program

Reduce the distance between sensors and
receiver to ensure reception

Find a new location for the transmitter or
receiver or use cable connection between the
base station and the sensors

recommended type
Eliminate the source of the interference or find a
new location for the sensor.
Faults are often restricted for limited periods
(radio communication) or can be easily
eliminated. If a unit, e.g. radio headphones,
remote babysitter, etc is operated nearby at 433
MHz, the period of activity is normally limited.
Most of these units can be changed to an
interference-free frequency. Such measures can
normally eliminate faults effectively.

Appendix 1

The following is a working example of how to save text files and create charts on other applications.

1. Using the Heavy Weather program, open the History window and save the weather data from the desired
history file as a text file by clicking on the Save as text button, enter a text file name and click OK.

2. Then open the text file that you have just saved (in Heavy Weather directory or your specific directory)
using a spreadsheet program like Excel.

3. The text import wizard window will open. Choose delimited as the separator for each data column and
click the next button.

4. The Heavy Weather program uses “tab” to separate data, so you should choose “tab” as delimiter in the
Excel program and click the next button

5. Next, select the appropriate data type (such as text or numbers) for each column of data. The default
setting General and this is usable and click the Finish button

6. The data is then imported into the Excel ready for the user to plot a graph. In this example we will use the
indoor temperature.

7. Next, the user has to create a valid time column as X-axis. In this example we have typed a date which
can be recognize by Excel manually in the cell M3, “2002/5/25 1:30”

8. Since the weather data in this example is generated with a 1-minute interval, we can use a formula to
generate the time column, we type “+M3+1/(24*60)” in the cell M4. This means adding 1 minute with
respect to cell M3 in cell M4 for the next set of data. Since Excel uses 1 day as a unit for time, we add
1/(24 x 60) = 1 minute with respect to the cell above.

9. Then we copy this formula to all cells in column K. The time axis is now complete.

Before plotting weather graph, please check that the decimal separator of the weather data is comma or point.
If comma is used (preferred by some European users), Excel will not be able to read the weather data directly.
Excel will define the data with comma as text format and thus will not be suitable for graph plotting as co­ordinates. There are two solutions to solve this problem. First and most the simplest way is to go into Heavy
Weather software and change the decimal separator to point in setup menu and then save the text file again.
Second, follow below procedures to change the decimal separator from comma to point from Excel.

A) Use the indoor temperature as the example. Go into to a new cell (for example, N3), type

“=VALUE(SUBSTITUTE(B3,”,”,”.”))” . Then an Excel readable indoor temperature reading is created

B) Then we copy this formula to all cells in column N. A set of valid indoor temperature readings are

ready for graph plotting

10. Next step is to make the plotting. From Excel, select Insert from the pull down menu then select Chart.
You will see the below screen. Then select XY as the chart type and click next

11. The Chart Source Data window is now open then select “Series” tab and click Next

12. Next, select the X-axis data by clicking the right-most icon in the “X Values :" And then, Choose the
appropriate data range. In this example, we select the time column we just made as the X-axis, since it is
located in a sheet named history1 and is from cell M3 to M62 (plot a graph between 1:30 to 2:29. The
“=history1!$M$3:$M$62” is now written in the box.

13. Next select the weather data as Y-Axis, we choose the indoor temperature as Y-Axis, so we have the
following screen.
A) When decimal separator is comma Choose column N.

B) When decimal separator is point. Choose column B.

14. As shown below, both the X and Y axis data range are selected. The variation of temperature within 1:30
to 2:29 can now be seen.

15. Click next to enter the below screen to dress up the chart, you can customize the Titles / Axes / Gridlines
/ Legend / Data Labels.

16. Click next, then select whether you want a separate sheet or a chart inside the data sheet.

17. Click finish to see the chart. In this chart, the variation of indoor temperature within 1 hour (1:30 to 2:39) is

plotted.
