With Indoor/Outdoor
Temperature and Humidity
USER’S MANUAL

INTRODUCTION
Thank you for selecting the Wireless Weather Forecaster.
This device combines precise time keeping, monitoring
and displaying of current temperature and humidity data
from up to three remote locations.
In this package you will nd:
• One main unit (receiver)
• One remote sensor (transmitter)
• One User’s Manual
Please keep this manual handy as it contains practical
instructions, technical specications and precautions.

INSTALLATION
The communication between the main unit (receiver) and
the remote sensor (transmitter) is wireless, making it easy
for installation. The remote temperature sensor transmits
data to the main unit, with an operating range of up to 100
feet (30 meters) in an open area.
The remote temperature sensor can be placed indoors or
outdoors, depending on the area where the temperature is
intended to be measured.
NOTE:
• It is critical to power the remote sensor BEFORE setting
up the main unit.
• It is critical to power up and test communication
between the remote sensor and the main unit BEFORE
permanently mounting outside.

BEFORE YOU BEGIN
• We recommend using alkaline batteries for the remote
sensor and the main unit. When outdoor temperatures
are below 0°C (32°F), it is recommended to use lithium
batteries.
• Avoid using rechargeable batteries. (Rechargeable
batteries cannot maintain correct power requirements.)
• ALWAYS install batteries in the remote sensor before the
main unit.
• Insert batteries before rst use, matching the polarity in
the battery compartment.
• Press RESET after each battery change with a paper clip
or similar tool.
• During initial set up, place the remote sensor close to the
main unit.
• After reception is established (remote readings will
appear on the main unit’s display), position the remote
sensor and the main unit within the effective transmission
range of up to 100 feet (30 meters).
• The main unit must be placed indoors.
NOTE:
• Avoid pressing any buttons on the main unit before the
remote readings are displayed.
• Transmission or reception range may be affected by
trees, metal structures, electronic appliances,
surrounding building materials and how the main unit and
transmitter are positioned.
• Place the remote sensor so that it faces the main unit
(receiver), minimizing obstructions such as doors, walls
and furniture.
• Though the remote sensor is weather-resistant, they
should be placed away from direct sunlight, rain or snow.
The optimal location for the remote sensor outdoors is
under the eaves on the north side of the building.

A

BATTERY INSTALLATION
When the temperature falls below freezing point 0˚C (32 ˚F),
battery voltage levels will be dropped and this may reduce
the transmission range. For optimum performance, we
recommend using lithium batteries.
NOTE: Install the batteries and select the channel before
mounting the remote sensor.
• Remove the screws from the battery compartment with a
small Phillips screwdriver (not included).
• Set the channel 1 through 3. The switch is located in the
battery compartment. Channel 1 is typically selected if
only one remote sensor is being used.
• Install 2 “AA” size alkaline batteries (not included)
matching the polarities shown in the battery
compartment.
• Select the temperature unit (°C/°F) using a pointed pin.
• Replace the battery compartment door and secure the
screws.
• Secure the remote sensor in the desired location.
MOUNTING
• The remote sensor can be placed on a at surface or
mounted on the wall in a vertical position.
• Use a screw, rather than a nail, for best mounting of the
sensor.
• When mounting the main unit on the wall or vertical
surface, fold the table stand back into the unit.
6

PLACEMENT
• The remote sensor should be placed under eaves or
a similar location with free air circulation sheltered from
direct sunlight and extreme weather.
• Ideally, place the remote sensor over soil, rather than
asphalt which would cause false readings.
• Avoid placing the remote sensor near sources of heat,
such as chimneys and heating elements.
• Avoid areas that collect heat from the sun and radiate
heat, such as metal, brick or concrete structures, paving,
and patios.
• The international standard for valid air temperature
measurements is 1.25meters (4 feet) above the ground.
OPERATION
Once batteries are installed, the remote sensor will start
transmitting temperature and humidity data to the main
unit.

GETTING STARTED
WEATHER FORECAST
This unit is capable of detecting the atmospheric pressure
changes. Based on collected weather data, it forecasts the
weather for the next 12 to 24 hours.
NOTE: The weather forecast accuracy is approximately
70%.The main unit display shows forecasted (predicted)
not current conditions. The SUNNY icon indicates clear
weather, even when displayed during the night-time.
PRESSURE OPERATION
The pressure window displays: current barometric
pressure, sea level pressure, and weather forecast. The
information contains a number of historical statistics:
pressure/ temperature/ humidity history bar-chart for the
past 24 hours.
Pressure can be measured in inHg, hPa/mBar or mmHg,
and altitude is determined in either meters or feet.
IMPORTANT: There are three viewing options available:
barometric pressure SEA LEVEL or LOCAL and
ALTITUDE. Local pressure is a measured value (cannot
be adjusted) while Sea Level & Altitude are variables that
you can enter. It is advisable to select and program only
one of the variables and to allow the unit to calculate the
third value.
The unit is designed to measure pressure changes at your
specic location, when LOCAL barometric pressure
is selected. Information for programming your unit, with
either Altitude or Sea Level values, may be obtained from
GPS readings or online from the Internet, etc.

PRESSURE OPERATION
SEA LEVEL barometric pressure provides you with
information about pressure changes at lower elevations
in your surrounding area. The SEA LEVEL pressure
value can be set to match your local metro area weather
information. (Sources – local TV or radio station, etc.)
SETTING INITIAL PRESSURE PARAMETERS
IMPORTANT: Allow the unit to set without touching ANY
buttons for about 6-8 minutes during the main unit initial
set up. This will give the unit time to synchronize with
remotes, stabilize pressure readings and set the default
settings.

CLOCK WINDOW
WWVB RADIO CONTROLLED TIME
The NIST (National Institute of Standards and Technology)
radio station (WWVB) is located in Ft. Collins, Colorado.
It transmits an exact time signal continuously throughout
most of the continental United States at 60 KHz frequency.
The main unit can receive this WWVB signal through
the internal antenna from up to 2,000 miles away. Due
to the nature of the Earth’s ionosphere, reception can
be limited during the daylight hours. The radio controlled
clock will search for an alternate station that receives the
atomic time signal from the NIST Atomic clock in Boulder,
Colorado.
The WWVB tower icon on the unit’s display will ash
indicating a radio signal reception from the WWVB station.
If the tower icon is not fully lit, or if the time and date are
not MODE automatically, please consider the following:
19

CLOCK WINDOW
• During night-time hours, atmospheric disturbances are
typically less severe and radio signal reception may
improve. A single daily reception is sufcient enough to
keep the clock accuracy within 1 second.
• Make sure the unit is positioned at 8 feet (2 meters)
distance from any interference source such as a TV,
computer monitor, microwave, etc.
• Within concrete wall rooms such as basements or ofce
buildings, the received signal may be weakened. Always
place the main unit near the window for better reception.
Once the atomic time signal is received, the date and time
will be set automatically, and the icon will appear.
• The atomic clock receiver is programmed to search
for the atomic time signal daily at 0:00, 3:00, 6:00, and
12:00 am.
• To enable or disable the atomic time receiver, press
and hold UP (▲) button for 3 seconds. If atomic time
reception is activated, a tower icon will start ashing. If
reception is disabled, the tower icon will disappear.
• If the time signal has not been received in 8 minutes, you
may set the time manually.
