ABOUT WWVB
The NIST (National Institute of Standards and Technology—Time
and Frequency Division) radio station, WWVB, is located in Ft.
Collins, Colorado and transmits the exact time signal continuously
throughout the United States at 60 kHz. The signal can be
received up to 2,000 miles away through the internal antenna in the
Weather Station. However, due to the nature of the Earth’s
Ionosphere, reception is very limited during daylight hours. The
Weather Station will search for a signal every night when reception
is best. The WWVB radio station derives its signal from the NIST
Atomic clock in Boulder, Colorado. A team of atomic physicists
continually measure every second of every day to an accuracy of
ten billionths of a second a day. These physicists have created an
international standard, measuring a second as 9,192,631,770
vibrations of a Cesium 133 atom in a vacuum. For more
information about WWVB please see the NIST website at
http://www.boulder.nist.gov/timefreq/stations/wwvb.htm

QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid
rechargeable batteries.
1.
2.
3.
4.
Have the indoor weather station and remote
thermo/hygro sensor 3 to 5 apart.
Batteries should be out of both units for 10 minutes.
Place the batteries into the remote thermo/hygro
sensor first then into the indoor weather station.
(All remote thermo/hygro sensors must be started
before the indoor weather station)
DO NOT PRESS ANY BUTTONS FOR 10
MINUTES.
In this time the indoor weather station and remote thermo/hygro
sensor will start to talk to each other and the indoor weather station
will show both the indoor temperature and humidity and the
outdoor temperature and humidity. If the indoor weather station
does not display all values after the 10 minutes please retry the set
up as stated above. After all values are displayed for 10 minutes
you can place your remote thermo/hygro sensor outdoors and set
your time.
The remote thermo/hygro sensor should be placed in a dry, shaded
area. The remote thermo/hygro sensor has a range of 80 feet. Any
walls that the signal will have to pass through will reduce distance.
An outdoor wall or window will have 20 to 30 feet of resistance
and an interior wall will have 10 to 20 feet of resistance. Your
distance plus resistance should not exceed 80 ft. in a straight line.
NOTE: Fog and mist will not harm your remote thermo/hygro
sensor but direct rain must be avoided.
5
To complete the set up of your indoor weather station
after the 10 minutes have passed please follow the
steps in the Detailed Set Up Guide
.
Note: The remote thermo/hygro sensor transmits a signal every 3
minutes; after the batteries have been installed, the indoor weather
station will search for the signal for a duration of 5 minutes. If
there is no temperature reading in the OUTDOOR LCD after 5
minutes, make sure the units are within range of each other, or
repeat the battery installation procedure.

DETAILED SET-UP GUIDE
BATTERY INSTALLATION
A. Remote Thermo/hygro Sensor
1. Pull the cylindrical rain cover off the remote
thermo/hygro sensor.
2. Remove the battery cover (located on the backside of
the remote thermo/hygro sensor, above the mounting
post and bracket).
3. Press the arrow and slide the battery cover off.
4. Observing the correct polarity install 2 AA batteries.
5. Replace battery cover, and place rain cover snugly
onto the remote thermo/hygro sensor.
B. Indoor Weather Station
1. Remove the battery cover. To do this, insert a solid
object in the space provided at the lower-central
position of the battery cover, then push up and pull
out on the battery cover.
2. Observe the correct polarity, and install 2 AA
batteries.
3. Replace the battery cover.
Note: Immediately after the batteries have been installed, each
LCD (Liquid Crystal Display) will flash, and a tone will sound.
Within a few seconds the indoor temperature, indoor relative
humidity, and the weather icons (sun and clouds) will be displayed.
If these items are not displayed remove the batteries for 10 seconds
and reinstall. If the outdoor temperature is not displayed within
four minutes, remove the batteries from both units, wait 10
seconds, and reinstall. The time will show -:-- and start searching
for the signal. If it successfully receives the time signal (reception
7
Battery
Cover
is achieved easiest at night), it will display the correct time
(factory setting is Eastern time zone).
PROGRAM MODE
Programming Note: If 20 seconds is allowed to pass during
programming modes, the unit will confirm/set the last information
entered—the display will stop flashing and return to normal timedate readings
TIME AND DATE
There are two methods by which the time and date can be set:
1) Automatically via WWVB reception (only need to set the
time zone in section III).
This method requires you to do nothing but wait for the signal to
be received, and to select a time zone (default is Eastern Time
Zone). Reception usually takes approximately 6-8 minutes during
optimal conditions. The best conditions for reception is at night,
between midnight and 6:00 am, when there is less atmospheric
interference. To keep your time as accurate as possible, the indoor
weather station conducts a WWVB search every night between
these hours, and overrides any time that has been set manually.
The WWVB tower icon (appearing in the TIME LCD) will flash
when a search is in progress, will remain steady when the signal
has been received, and nothing will be displayed in all other
situations. If the WWVB time has not been received after 10
minutes of battery installation, you may manually set the time or
leave the time function alone (reception will occur regardless).
8
2) Manually (performed throughout the programming mode.
When programming, the manual setting of time and date is not
necessary and can be skipped. Any time information programmed
will be over-written by the reception of the WWVB signal.

FEATURES OF THE WS-7391U
I. Weather Forecast
The weather forecasting feature is estimated to be 75% accurate.
By adjusting the sensitivity setting, you can achieve a better
accuracy of forecast. The weather forecast is based solely upon the
change of air pressure over time. In areas where the weather is not
affected by the change of air pressure, this feature will be less
accurate.
1. Weather Icons
There are 3 possible weather icons that will be displayed
in the TENDENCY LCD:
Sunny—indicates that the weather is expected to improve
(not that the weather will be sunny).
Sun with Clouds—indicates that the weather is expected
to be fair (not that the weather will be sunny with clouds).
Clouds with Rain—indicates that the weather is expected
to get worse (not that the weather will be rainy).
The weather icons change when the unit detects a change
in air pressure. The icons change in order, from “sunny”
to “partly sunny” to “cloudy”. It will not change from
“sunny” directly to “rainy”, although it is possible for the
change to occur quickly. If the symbols do not change
14
then the weather has not changed or the change has been
slow and gradual. If this happens on a regular basis, it
may be necessary to adjust the weather forecast
sensitivity.
2. Weather Tendency Arrows
Other possible displays in the TENDENCY LCD are 2
weather tendency arrows, one that points up and one that
points down. These arrows reflect current changes in the
air pressure: an arrow pointing up indicates that the air
pressure is increasing and the weather is expected to
improve or remain good, an arrow pointing down
indicates that the air pressure is decreasing and the
weather is expected to become worse or remain poor. No
arrow means the pressure is stable.
A storm can be expected if there is a drop of 4 hPa or
more in less than 6 hours, the rain icon is displayed, and
the downward pointing arrow is flashing. The flashing
will stop when the air pressure stabilizes or begins to rise.
II. Indoor Temperature, Humidity, and Comfort Level
Indicator
The current indoor temperature (viewed on the left) and relative
humidity (viewed on the right) are displayed in the INDOOR LCD.
The comfort level indicator is located at the center of the INDOOR
LCD. The comfort level indicator will display a happy face icon
when the temperature is between 68°F and 79°F (20°C and
25.9°C), and the humidity is between 45% and 64%. A sad face
icon will be displayed when the temperature and humidity are
outside the mentioned ranges.
15
III. Outdoor Temperature and Humidity
The outdoor temperature and humidity is viewed in the
OUTDOOR LCD. When there is more than one remote sensor
unit in operation a “boxed” number will appear to the right of the
temperature. This indicates which remote sensor unit (1, 2, or 3) is
currently displaying its data in the OUTDOOR LCD. (This feature
is explained in further detail in the following section—Adding
Remote Sensors).
IV. Minimum and Maximum Temperature Records (Indoor,
Outdoor and Resetting)
The WS-7391U keeps a record of the minimum and maximum
temperatures for both the indoor and outdoor sections. These
temperatures can be viewed directly underneath the current indoor
and outdoor temperatures. The minimum recorded temperature is
on the left and the maximum-recorded temperature is on the right.
Resetting the Minimum and Maximum Records
To reset both the indoor and outdoor temperature records press and
hold the reset button for 5 seconds.
Note: This will reset both the indoor and outdoor records, it is not
possible to only reset one or the other.
16
V. Adding Additional Remote Sensors (Optional)
The WS-7391U is able to receive signals from 3 different
remote sensors. These extra remote sensors can be
purchased through the same dealer as this unit. A TX4U
will monitor the temperature and humidity, a TX3U will
monitor temperature and display the temperature on its
LCD and the TX3UP will monitor the temperature via a
probe for measuring soil or water temperatures.
Note: When setting up multiple units it is important to
insert batteries first into all the remote sensors, and in
numeric sequence. Second install batteries into the
indoor weather station. Transmission problems will arise
if this is not done correctly and if the total time for set-up
exceeds 6 minutes.
VI. Set-up of Multiple Units

The minimum and maximum temperature of the
additional remote sensor will be displayed below the
current temperature of the remote sensor in the
OUTDOOR LCD.
To reset the minimum and maximum temperature
readings it is necessary to select which remote sensor
you wish to reset. Press and hold the “RESET”
button for 5 seconds and the records for the selected
remote sensor will be reset.
18
VIII. Mounting
Note: Before permanently mounting ensure that the
indoor weather station is able to receive WWVB signals
from the desired location. Also, extreme and sudden
changes in temperature will decrease the accuracy of the
indoor weather station. Changes in elevation will result
with inaccurate weather forecasting for the next 12 to 24
hours. These changes will require a 12 to 24 hour wait
before obtaining reliable data. To achieve a true
temperature reading, avoid mounting where direct
sunlight can reach the remote thermo/hygro sensor. We
recommend that you mount the remote thermo/hygro
sensor on a North-facing wall. The transmitting range of
the remote thermo/hygro sensor is 80ft. Obstacles such
as walls, concrete, and large metal objects can reduce the
range. Place both units in their desired location and wait
approximately 10 minutes before permanently mounting
to ensure that there is proper reception. The indoor
weather station should display a temperature in the
OUTDOOR LCD within 4 minutes of setting up.
1. Remote Thermo/hygro Sensor
A. Mounting With Screws
1. Remove the mounting bracket/receptor from the
packaging.
2. Place the mounting bracket over the desired mounting
surface.
3. Through the 2 screw holes of the bracket mark the
mounting surface with a pencil.
4. Where marked, start the screw holes using the provided
screws.
19
5. Remove screws from the mounting surface.
6. Align the mounting bracket with the started screw holes.
7. Screw mounting bracket onto the mounting surface. The
screws should be flush with the bracket.
8. Fit the mounting post (on the back of the remote
thermo/hygro sensor) into the receptor of the mounting
bracket.
B. Mounting With Adhesive Tape
1. With a nonabrasive solution, clean and dry the back of the
mounting bracket and the mounting surface to ensure a
secure hold. The mounting surface should be smooth and
flat.
2. Remove the protective strip from one side of the tape.
Press firmly onto the designated area on the back of the
mounting bracket.
3. Remove the protective strip from the other side of the
tape, and situate the mounting bracket. Firmly press the
mounting bracket onto the mounting surface.
4. Fit the mounting post into the receptor of the mounting
bracket.
20
2. The Indoor Weather Station
1. The WS-7391U is a wall mount only indoor weather
station. To mount the display on your wall:
2. Fix a screw (not included) into the desired wall, leaving
approximately 3/16 of an inch (5mm) extended from the
wall.
3. Place the indoor weather station onto the screw using the
hanging hole on the backside.
4. Gently pull the indoor weather station down to lock the
screw into place.
