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 Wireless Temperature Station.
However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The temperature 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 Wireless Temperature Station and remote temperature sensor 3 to 5
feet apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote temperature sensor first then into the
Wireless Temperature Station.
(All remote temperature sensors must be started before the Wireless
Temperature Station)
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the Wireless Temperature Station and remote temperature sensor will
start to talk to each other and the display will show both the indoor temperature and
an outdoor temperature. If the Wireless Temperature Station does not display both
temperatures after the 15 minutes please retry the set up as stated above. After both
indoor and outdoor temperatures are displayed for 15 minutes you can place your
remote temperature sensor outdoors and set your time.
The remote temperature sensor should be placed in a dry, shaded area. The
temperature sensor has a range of 330 feet. Keep in mind that the 330 feet is in open
air with no obstructions and that radio waves DO NOT curve around objects. Actual
transmission range will vary depending on what is in the path of the signal. Each

5
obstruction (roof, walls, floors, ceilings, thick trees, etc.) will effectively cut signal
range in half.
Example: A Wireless Temperature Station with a 330 feet range is mounted on an
interior wall, so that the signal has to pass through one interior wall, one exterior
wall, and across the 10 feet width of the room between the 2 walls. The first wall
will reduce the range to 165 feet, and the second wall will reduce the range to 87
feet. Factoring in the 10 foot room, this leaves a maximum of 77 feet of remaining
signal range.
This allowance is typically enough for a frame wall with non-metallic siding;
however certain materials can reduce range even further. Metal siding, stucco, and
some types of glass can reduce signal range by as much as ¾ or more, compared to
the ½ reduction typical of most obstructions. It is possible to receive a signal
through these materials, however maximum range will be much less due to their
tendency to absorb or reflect a much larger portion of the sensor’s signal.
To complete the set up of your Wireless Temperature Station after the 15 minutes
have passed please follow the steps that follow in the Detailed Set-Up Guide.
DETAILED SET-UP GUIDE
I. BATTERY INSTALLATION (When one temperature sensor is being
used)
1. First, insert the batteries to the temperature sensor (see “A. Remote
Temperature sensor” below).
2. Within 30 seconds of powering up the sensor, insert the batteries to the
Temperature Station (see “B. Wireless Temperature Station” below). Once
the batteries are in place, all segments of the LCD will light up briefly.
Following the indoor temperature and humidity, and the time as 12:00 will
be displayed. If they are not shown in LCD after 60 seconds, remove the
batteries and wait for at least 60 seconds before reinserting them. Once the
indoor data is displayed user may proceed to the next step.
3. After the batteries are inserted, the Temperature Station will start receiving
data signal from the sensor. The outdoor temperature should then be
displayed on the Temperature Station. If this does not happen after 2
minutes, the batteries will need to be removed from both units and reset
from step 1 and the signal reception icon is no longer shown.

6
A. REMOTE TEMPERATURE SENSOR
1. Remove the mounting bracket. The
bracket snaps on and off easily.
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.
B. WIRELESS TEMPERATURE 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.
*When the signal is successfully received by the Wireless Temperature
Station, the icon will be switched on. (If not successful, the icon will not be
shown in LCD) So the user can easily see whether the last reception was

successful (icon on) or not (icon off). On the other hand, the short blinking
of the icon shows that a reception is being done now.
• If the signal reception is not successful on the first frequency (915MHz) for
45 seconds, the frequency is changed to 920MHz and the learning is tried
another 45 seconds. If still not successful the reception is tried for 45 seconds
on 910MHz. This will also be done for re-synchronization.
PROGRAM MODE
Programming Note: If 30 seconds is allowed to pass, or the CH 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 III through XII, 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.
I. PROGRAMMING SEQUENCE AND DEFAULT SETTINGS
