ABOUT WWVB (Radio Controlled Time)
The NIST (National Institute of Standards and Technology—Time and Frequency Division) WWVB radio station is
located in Ft. Collins, Colorado, and transmits the exact time and date 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 is continually measuring every second,
of every day, to an accuracy of ten billionths of a second per 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
on the atomic clock and 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. Have the indoor weather station, remote temperature/humidity sensor and wind speed sensor 3 to 5 feet
apart.
2. Insert the telephone plug (RJ-11) from the wind speed sensor into the receptacle on the remote
temperature/humidity sensor.
3. Insert the telephone plug (RJ-11) from the rain sensor into the receptacle on the remote
temperature/humidity sensor (optional; sold separately)
4. Batteries should be out of both the indoor weather station and remote temperature/humidity sensor units
for 10 minutes.
5. Place the batteries into the remote temperature/humidity sensor first then into the indoor weather
station.
6. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the indoor weather station and remote temperature/humidity sensor (and rain sensor if any) will start to talk
to each other and the display will show the indoor temperature/humidity, outdoor temperature/humidity and wind
speed. If the indoor weather station does not display all information after the 15 minutes please retry the set up as
stated above. After all information has been displayed for 15 minutes you can place your sensors outdoors and set
your time.
Important Notes on Set-up and Operation
•The remote temperature/humidity sensor is both the source of power for both outdoor sensors and source of
transmission for all remote sensor data.
•The remote temperature/humidity sensor should be placed in a dry, shaded area.
•Fog and mist will not harm your remote temperature/humidity sensor but direct rain must be avoided.
•Direct rainfall will not harm the wind speed sensor.
•The remote temperature/humidity sensor has a range of 330 feet. Any walls that the signal will have to pass
through will reduce distance. An outdoor wall or window can have up to 30 feet of resistance and an interior wall
can have up to 20 feet of resistance. Your distance plus resistance should not exceed 330 ft. in a straight line.
•The remote temperature/humidity sensor transmits a signal every minute. After the batteries have been installed,
the indoor weather station will search for the signal for a duration of 15 minutes. If there is no temperature or
humidity reading in the OUTDOOR LCD or wind speed in the WIND SPEED LCD after 15 minutes, make sure the
units are within range of each other, or repeat the battery installation procedure.
•If a button is pressed before the indoor weather station receives the signal from the remote temperature/humidity
sensor, you will need to follow the battery installation procedure again.
To complete the set up of your new wireless weather station after the 15 minutes have passed please follow the steps
that follow in the Detailed Set-Up Guide.

DETAILED SET-UP GUIDE
BATTERY INSTALLATION
The first step to powering up the weather station is to insert the connector (RJ11) at the end of the wire attached to
the wind speed sensor to the remote temperature/humidity sensor. Please ensure when doing this that the connector
is inserted with the proper orientation. When seated properly you will hear the connector ‘click’ in place.
A. REMOTE TEMPERATURE/HUMIDITY
1. Remove the mounting bracket and humidity hood.
2. Remove the battery cover by sliding the cover down.
3. Observing the correct polarity install 2 AA batteries. The batteries will fit tightly (to avoid start-up
problems make sure they do not spring free).
4. Replace the battery cover by sliding upwards. Be sure battery cover is on securely.
5. Replace the humidity hood.
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 3 AA batteries.
3. Replace the battery cover.
C. RAINFALL SENSOR (optional)
The optional Rain Sensor does not need batteries to operate. Simply insert the telephone plug (RJ-11) of
the rain sensor into the receptacle on the remote temperature/humidity sensor.
Note: Immediately after the batteries have been installed, the LCD (Liquid Crystal Display) will flash.
Within 15 seconds the indoor temperature, indoor relative humidity, and the weather icons (sun and
clouds) will be displayed. If not, remove batteries for 10 seconds and reinstall. If the outdoor
temperature is not displayed within four minutes, remove batteries from both units, wait 30 seconds,
and reinstall making sure to install batteries into the remote temperature sensor first. The time will
show -:-- and start searching for the WWVB signal. If it successfully receives the time signal (usually
at night), it will display the correct time (default time-zone is Eastern). You will need to adjust the time
zone to match your local time.
PROGRAM MODE
Programming Note: If 30 seconds are allowed to pass, or the WIND/SNZ button is pressed during the
programming mode, the unit will confirm/set the last information entered—the display will stop flashing and return
to normal time-date readings. If you don’t leave the program mode during the programming of sections IV through
XI, you can advance to step 4 of the next program setting. If you do leave the program setting (or want to
program a specific setting) follow each instructional step to program that setting.

This method requires you to do nothing, except wait for the signal to be received, and to select a time
zone. Reception usually takes approximately 10 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 manually set time. The WWVB tower icon (appearing in the
TIME LCD) will flash when a signal-search is in progress and a signal is being received, and will remain
steady when the signal has been received. 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).

FEATURES OF THE WS-9046U
I. WEATHER FORECAST
The weather forecasting feature is estimated to be 75% accurate and is for the next 12 to 24 hours. The
weather forecast is based solely upon the change of air pressure over time. The WS-9046U averages past
air-pressure readings to provide an accurate forecast—creating a necessity to disregard all weather
forecasting for 12-24 hours after the unit has been set-up, reset, or moved from one altitude to another (i.e.
from one floor of a building to another floor). In areas where the weather is not largely affected by the change
of air pressure, the sensitivity setting should be set to 1. In areas where the air pressure changes more
rapidly (such as coastal areas) the sensitivity setting should be set to 3.
A. WEATHER ICONS
There are 3 possible weather icons that will be displayed in the FORECAST 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).

These icons indicate the expected weather change in the next 12 to 24 hours. The icon does not give
an exact prediction of the weather, however it should be viewed as a generalization of the expected
weather change (for example a “sunny” icon indicates the weather is expected to improve).
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” or the reverse. 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 then the
weather has not changed, or the change has been slow and gradual.
B. WEATHER TENDENCY ARROWS
Other possible displays in the FORECAST LCD are 2 weather tendency arrows, one that points up
(on the left side of the LCD) and one that points down (on the right side of the LCD). 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.
II. INDOOR TEMPERATURE, HUMIDITY, AND COMFORT LEVEL INDICATOR
The current indoor temperature and relative humidity are displayed in the INDOOR LCD.
The comfort level indicator is located at the bottom left of the INDOOR LCD. The 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.
III. OUTDOOR TEMPERATURE AND HUMIDITY
The temperature and humidity received from the remote temperature/humidity sensor is viewed in the
OUTDOOR LCD.
