1. Introduction
Thank you for purchasing this Professional Remote Weather
Station.
Designed for everyday use, the eather station ill prove to
be an asset of great value for your personal use in the home
or office.
Please read this instruction manual thoroughly to fully
understand the correct operation of your eather 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 eather data from the
follo ing three outdoor sensors:
1) Thermo-Hygro Sensor
2) Wind Sensor
3) Rain Sensor
The received data is continuously updated to bring you the
latest eather information on the base station’s LCD. The
outdoor thermo-hygro sensor is the main data communication
unit since both the ind and rain sensors are connected to the
thermo-hygro sensor for operating po er and rely on it to
communicate to the base station. Weather data sent from the
thermo-hygro sensor can be done by ireless 433MHz
transmission (up to 330ft in open space) or by cable
connection.
Using the enclosed 6.5ft computer cable and CD-ROM, you
can install the Heavy Weather soft are to your PC and
access the latest eather information from your PC and
upload up to 175 sets of recorded eather data received by
the base station. Recorded data can be used to generate
statistics and charts onto your spreadsheets (175 sets of data
is stored in the base even if the PC is s itched OFF). The
soft are itself does not set any limits as to ho many data
sets can be transferred to PC.

This eather station is designed to ork easily ith your PC,
simply connect and disconnect the PC cable at any time.

settings by the user
• COM port for easy connection to your PC
• All the eather data from the base station and up to 175
sets of eather history data ith user adjustable

your PC
eatures of the Thermo-Hygro Sensor
The thermo-hygro sensor measures the outdoor temperature
and relative humidity. It also collects the readings from the
rain and ind sensors before transmitting the data to the base
station by ireless 433MHz or by the 32ft cable included in
this set.
eatures of Wind sensor
The ind sensor measures ind speed and ind direction and
sends the data to thermo-hygro sensor, hich in turn
transmits the data to the base station. Operating po er is
taken from the thermo-hygro sensor using a 32ft cable
connection.
eatures of Rain sensor
The rain sensor measures the rainfall and sends the data to
thermo-hygro sensor, hich in turn transmits the data to the
base station. Operating po er is taken from the thermo-hygro
sensor by a 32ft cable connection.

5. Setting up
First, choose to use the adaptor (included in this set) or
batteries for operation. Both these methods allo for
operation using ireless 433MHz transmission or cable
connection bet een the base station and the sensors and
setting up for both methods is as follo s:
Base Station:
Battery
compartment
PC COM
Port
Socket for sensor
DC 6.0V
socket

Setting up using batteries:
Important: To avoid operating problems, please take note
of battery polarity if inserting any batteries
1) Pull a ay the rain cover of the thermo-hygro sensor to
reveal the three sockets (for the ind sensor, rain sensor
and the base station)
2) Connect the attached cables of ind 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 the three sockets and insert 2 x AA, IEC
LR6, 1.5V batteries and close the cover
4) Open the base station’s battery cover located at the back
of the unit and insert 3 x AA, IEC LR6, 1.5V batteries into
the battery compartment and close the battery cover

Setting up using the AC adaptor:
1) Po er up all the sensors as described in setting up using
batteries above
2) Using the AC adaptor (included), plug it into the po er
outlet and po er 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 po ered up (for
example after a change of batteries), a random security code
is transmitted and this code must be synchronized ith the
base station to receive eather data.
When the base station is po ered up, a short beep ill sound
and all LCD segments ill 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 ill 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 the eather station’s time and date display but also
functions as the time and date source for all of this eather
station’s memory and history values using the time and date
information received from the atomic clock.
EL backlight:
When using the po er adapter or under battery operation, the
LCD backlight ill s itch on for 15 seconds hen any button
is pressed.
6. Operation using cable connection or wireless
433MHz
Cable Connection:
Using this method of operation ill provide interference free
transfer of the eather data from the sensors to the base
station. The data sending interval from the sensors to the
base station ill also be more frequent compared to using

10
433MHz transmission and ill result in higher po er
consumption. Batteries ill have a shorter life span for cable
connection compared to using 433MHz ireless transmission.
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 ill
automatically continue reading the data from the sensor.
The user may at any time s itch 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 ill automatically change to using
433 MHz for reception of the eather data from the sensors.
The data receiving intervals are as follo s:
- Using cable connection data is updated every 8
seconds.
- Using ireless 433 MHz data is updated from 16 to 128
second intervals depending on ind speed and rain
activity.
Using the AC adaptor to operate the base station ill also
supply po er to the sensor if the cable is connected to it.
Batteries used for 433MHz transmission may be left in the
sensor hen using cable connection for po er back up in
case of AC po er failure. A loss of po er ould
desynchronize the base station and the sensor and no
eather data ill be received. To synchronize the units so
that the eather data can be received, press and hold the
PLUS (+) key for 2 seconds. In general, batteries that ill not
be used for long periods should be removed to avoid leakage.
Wireless 433MHz transmission:
Using 433MHz ireless transmission of eather data from the
sensor to the base station ill provide users greater freedom
as to here units can be positioned ithout the need to be
restricted by cable.
Note:
If no outdoor eather 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,
