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 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 are
continually measuring every second, of every day, to an accuracy of ten billionths of
Figure 2

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.
QUICK SET-UP GUIDE
1. Insert two AA batteries into the Thermo Hygro Transmitter.
2. Insert two AA batteries into the WEATHER STATION.
3. Wait 5 minutes or until the outdoor temperature and humidity are
displayed in the OUTDOOR LCD (Liquid Crystal Display).
4. Wait 6-10 minutes (in ideal reception conditions) for the WWVB time
to be displayed in the TIME LCD. If the WWVB takes longer to set,
you may manually set the time (see complete instructions). Or you can
wait until after the weather station conducts its programmed search at
the ideal reception time period of 12:00 AM to 6:00 AM.
5. Mount the units ensuring that all units are sending and receiving
signals.
Note: The Thermo Hygro Transmitter transmits a signal every 3 minutes.
After the batteries have been installed, the 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
I. BATTERY INSTALLATION
A. THERMO HYGRO TRANSMITTER
1. Pull the cylindrical rain cover off the transmitter.
2. Remove the battery cover (located on the backside
of the transmitter 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 transmitter.

B. 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.

Cover
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 not, then remove
batteries for 10 seconds and reinstall. If the outdoor temperature is not
displayed within four minutes, remove 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 (usually at night), it
will display the correct time (default is Eastern).

PROGRAM MODE
Programming Note: If 30 seconds is allowed to pass or either the IN or the
OUT button is pressed during programming modes, the unit will 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 III through VIII, you can advance to step 3 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.

corresponding to the operation that you want to perform.
II. 12 OR 24 HOUR TIME SETTING
1. Press and hold the SET button for 3 seconds or until “12 h”
flashes in the DATE LCD.
2. Press the CH button to toggle between 12 and 24-hour time.
3. Press the SET button to confirm the 12/24-hour setting and to
advance to Time Zone Setting.
III. TIME ZONE SETTING
The default time zone is EST “-5hr” (Eastern Standard Time). To
change this setting:
1. Press and hold the SET button for 3 seconds or until “12 h”
OR “24 h” flashes in the DATE LCD.
2. Press the SET button 1 more time to enter the Time Zone
setting mode. The default Time Zone “-5” will flash in the
DATE LCD.
3. Select your appropriate time zone using the CH button.
During selection of the Time Zone, the 3 letter abbreviations
for the time zones found in North America will flash across

the TIME LCD. Observe the chart below showing the
corresponding abbreviations, time zones and codes.
TIME ZONES
GMT 0
Atlantic -4
EST; Eastern -5
CST; Central -6
MST; Mountain -7
PST; Pacific -8
ALA; Alaska -9
HAW; Hawaii -10
Note: There are more time zones represented by numbers than there are
represented by 3 letter abbreviations. If you live in North America you
need only be concerned with the ones in the chart above.
4. Press the SET button to confirm and advance to the Daylight
Saving Time setting.
IV. DAYLIGHT SAVING TIME (DST) SETTING
1. Press and hold the SET button for 3 seconds or until “12 h” or
“24 h” flashes in the DATE LCD.
2. Press the SET button 2 more times to reach the DST selection
mode. “DST 1” is the default setting and will be flashing in
the DATE LCD.
3. Press the CH button to select “DST 0” or “DST 1.”
4. “DST 0” indicates that the feature is off and the WWVB will
not change times automatically. “DST 1” indicates that the
feature is on and the WWVB will change times automatically.
Note: Some locations (Arizona and parts of Indiana) do not
follow Daylight Saving Time, and should select “DST 0.”
5. Press the SET button to confirm and advance to the Time
setting mode.

V. TIME
There are two methods by which the time can be set:
A) Automatically via WWVB reception or
B) Manually
A. WWVB (Remote Control Time)
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 6-10 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 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, 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).
B. MANUAL TIME SETTING
1. Press and hold the SET button for 3 seconds or until “12h”
flashes in the DATE LCD.
2. Press the SET button 3 more times (until the hour digit
flashes in the TIME LCD).
3. Press the CH button to change the hour.
4. Press the SET button to confirm the hour setting, and to
advance to the minute setting mode.
5. The minute digits will be flashing. Press the CH button to
change the minutes. Increasing the minutes by increments of 1
with each press of the CH button.
6. Press the SET button to confirm the minutes and to advance to
the Day, Date and Year setting mode.

Note: In 12h mode, “PM” will appear to the left of the time
during PM hours. If the time is not within the PM hours, nothing
will be displayed. Be sure to set the time to the correct AM/PM
time to ensure automatic reception at optimal times.
VI. SETTING THE DAY, DATE, AND YEAR
1. Press and hold the SET button for 3 seconds or until “12 h” or
“24 h” flashes in the DATE LCD.

setting mode.
Note: “MO” (representing Monday) is the default setting for the
weekday, “1.1” is the default setting for the numeric month and
day and “1999” is the default setting for the year. The day, date
and year will be automatically set once the WWVB signal is
received. However, the day, date and year can be manually set and
will flash respectively in the DATE LCD during manual
programming.
