Setting up using the AC adaptor:
To operate using cable connection, simply use the enclosed 32ft
cable and connect the thermo-hygro sensor to the base station. Once
the connection is detected, the base station will automatically con-
tinue reading the data from the sensor.
1) Power up all the sensors as described in setting up using batter-
ies 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
DC 6.0V socket located on the side of the base station
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 auto-
matically change to using 433 MHz for reception of the weather data
from the sensors.
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.
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.
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 WWVB radio controlled time reception.
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.
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 history
values using time and date information.
Wireless 433MHz transmission:
LCD backlight:
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.
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.
Note:
6.
Operation using cable connection or wireless 433MHz
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 station to sensors. Without being synchronized, weather data
will not be received.
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.

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 dis-
played on the LCD.

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
Firstly, check that the wind-fan and the wind-vane can rotate freely
before fixing the unit. For correct and accurate readings it is impor-
tant 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
Ø.63” – Ø1.3”).
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 unit. It is important to 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 re-
ceived, the system can be affixed. Also if you have selected to use
cable connection, ensure that distances can reach all desired loca-
tions before affixing any unit permanently
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 sta-
tion.
Mounting the Rain Sensor
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
Base portion
Wind-vane
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 re-
duced 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 and
the mounting surface (test by pouring clean water).
Wind-fan

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
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 synchro-
nize 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.
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).
Do not remove batteries or unplug the AC adaptor of the base station
otherwise all 175 sets of recorded weather history data for transfer-
ring to the PC will be lost (for full details of PC use, please see PC
user manual in the enclosed Heavy Weather CD-ROM).
Mounting the thermo-hygro Sensor
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 previ-
ous user defined values and all weather history recordings.

Function Description of the Weather Station
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.
After setting up, the following data will be displayed in different sec-
tions on the LCD. If this is not the case please observe the notes on
“Interferences” below.
LCD Section 1:
Sunny

Rainy
Time, date, seconds, time zone,
weather forecasting icons with

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 6 inHg, 9 inHg to 12
inHg (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 inHg setting compared to 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.

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
Download from Www.Somanuals.com. All Manuals Search And Download.
8.85 inHg to 32.45 inHg (standard air pressure at an altitude of
30,000ft is around 8.85 inHg).
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:
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 sur-
roundings. 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 repre-
sent readings your their area (see Basic Programming Modes be-
low).

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 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. 59°F and a relative humidity
of 50% the dewpoint will be about 41°F, at 80% humidity about
53.6°F. At a relative humidity of 100% saturation 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 II.
It represents not the real measured but the 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. 46.4°F and calm winds a person 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

Basic Programming Modes
Manual time setting
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 the WWVB tower icon
will flash.
Manual Setting modes
The manual setting mode allows the user to change several basic
settings, which is done by accessing one mode after the other simply
by pressing the SET key. After the final mode, or if no key is pressed
for 30 seconds, the manual setting returns to the normal display
mode.
•
If reception has been unsuccessful, then the WWVB tower
icon will not appear but reception will still be attempted the
following hour within the time frame
The manual setting takes the user through the following modes:
1. 8 level LCD contrast setting (default level 5)
2. Manual time setting (hours/minutes)
•
If reception has been successful, the received time and date
will overwrite the manually set time and date and no further
reception is attempted until the following day
3. 12/24h time display select (default 12 hours)

inHg) using the PLUS (+) or MINUS (-) keys
13)Press the MIN/MAX key to confirm and return to the normal dis-
play.
When entering the alarm set mode for a specific weather or tempera-
ture condition, the corresponding alarm is automatically enabled (ON)
when the SET key is pressed, regardless of its previous setting and
the alarm value will flash to indicate that it has been activated. Press
the ALARM key to confirm the setting and continue pressing the
ALARM key to toggle through each alarm mode until it returns to the
normal display mode or press the MIN/MAX key at any time to exit the
alarm setting modes.
When a set weather alarm condition has been activated, that particu-
lar alarm will sound and flash for approximately 2 minutes but will
continue to flash until weather conditions have become more steady.
Storm warning alarm ON/OFF
After storm warning alarm setting, the next mode to appear after
pressing the SET key is the storm warning ON/OFF. Use the PLUS
(+) or MINUS (-) key to change the status to AON or AOFF. Default
setting is ON:
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 disabling the
low alarm (i.e. temperatures <-14°F won’t trigger alarm, but tempera-
tures >+86°F will).
Should the air pressure drop equal or below the pre-set inHg value
within the last 6 hour period, then the downward tendency arrow will
flash as an indication of possible storm. The base station will take
hourly measurements as a point of reference. The storm-warning
indicator will stop flashing once the air pressure becomes more sta-
ble.

Hysteresis
17. Accessories: adding cable extensions
To compensate for fluctuation of the measured data, which may
cause the weather alarm to sound constantly if the measured reading
is close to user set level, a hysteresis function has been implemented
for each weather alarm. For example, if the high temperature alarm is
set to +77°F and the current value moves to +78°F, the alarm will be
activated (if it has been enabled). Now when the temperature drops to
+76°F or below and thereafter again increases to beyond +77°F, the
data will be blinking, but no alarm will be activated. It has to drop to
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:
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 distance.

Auto memory for stored values
When securing the cables during mounting, ensure that base station
can receive the weather data since increasing the cables lengths may
also increase levels of interference and result with reception difficul-
ties. Interference levels will greatly depend on the surrounding area
for example setting up on or near metal piping may considerably
reduce reception.
The base station has a memory back up system, which is used to
memorize user-defined settings for when the batteries are changed or
if a power failure occurs. User defined units are automatically updated
each time these are changed. The base station will memorize the
following user defined units:
For best results, do not to add more than 32ft of extension cable from
item to item onto the existing cable lengths as this may reduce recep-
tion levels. Again, reception and interference levels will greatly de-
pend on the surrounding environment at your point of mounting.

1. Open the battery cover
2. Remove the old batteries and insert with new ones of the rec-
ommended type and replace the cover
Problem & cause
Distance between
transmitters and re-
ceiver too long.
Remedy
Reduce distance between transmitters
and receiver to receive signal
Once the sensor is powered up, press and hold the PLUS (+) key for
approx. 2 seconds in the normal display mode, the base station will
sound a short beep and synchronize to the sensor otherwise no
weather data will be received.

1. Connect power adaptor to base station and power 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 recom-
mended type and replace the cover
and/or base station. Neighbors using
electrical devices operating on the
433MHz signal frequency can also
on the same frequency) cause interference with reception
No Reception after
adding extension ca-
bles
Find a new location for the sensors
and/or base station. Recommend not
adding more than 32ft extension ca-
bles between units to the existing
cable lengths, as this will increase the
chance of data reception problems.
Press and hold the PLUS (+) key for 2
seconds to synchronize the base sta-
tion to the sensors for weather data
reception. If still no signal, then
change the sensor batteries and syn-
chronize the units again.
This method of battery replacement will result in no loss of MIN/MAX
and history data. However in case of possible power failure, the base
station will lose the MIX/MAX and all weather data recordings and 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 environment
by properly disposing of all used-up batteries and accu-
mulators at designated disposal points. Never dispose of
batteries in a fire as this may cause explosion, risk of fire
or leakage of dangerous chemicals and fumes

Quite frequently interferences are only of a temporary nature and may
be easily overcome. If there are wireless headsets, remote babysit-
ters or other devices working on 433MHz in your house or in the vicin-
ity, 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.

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 that 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.

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 Requirements
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 back-
light.
•
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 sensor
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.

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 tendency indicator
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 chill
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.
Download from Www.Somanuals.com. All Manuals Search And Download.
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 Weather 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 the Heavy Weather software
6.1 Activating the weather software
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.

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
Temperature
Humidity
Hysteresis
1.8ºF
3% RH
Air pressure
Rainfall 24h
Rainfall 1h
Wind
0.0295 inHg
0.1968 inch
0.01968 inch

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.
14.0 Problems and Solutions
Problems
Cause
Solutions
Undefined values after starting
up on the PC
Loose connection of cables
- Ensure that the PC COM port cable is
properly connected to the base station
(receiver).
- Ensure that the correct COM is selected in
the set up menu on the program
Reduce the distance between sensors and
receiver to ensure reception
No 433MHz reception
Distance between the base
station and the sensors are
too great
No reception within a short
distance
Interfering material between
sensor and receiver (thick
walls
Find a new location for the transmitter or
receiver or use cable connection between the
base station and the sensors
Batteries of sensors or receiver
empty
Faulty batteries
Change batteries to use those of the
recommended type
Sensors superimposed by
source of interference
Radios, headphones or
loudspeakers and items
operating on the same
433MHz frequency
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.
Download from Www.Somanuals.com. All Manuals Search And Download.
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 co-
ordinates. 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.
