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 Temperature Clock.
However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The Temperature Clock 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.

QUICK SET-UP GUIDE

1) Insert two AAA batteries into the remote transmitter.

2) Insert two AA batteries into the Temperature Clock.

3) Wait 10 minutes for WWVB reception and remote temperature.

4) If there is no WWVB reception, manually set the time and date (instructions

in the Program Mode).

5) Program the settings.

6) Mount the WS-8011UM in a suitable location, where WWVB and

transmitter signals can be received.

7) Mount the transmitter where remote temperature measurement is desired

(on the North side of a house for example).

QUICK SET-UP GUIDE

Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.

1. Have the indoor station and outdoor remote 3 to 5 apart.

2. Batteries should be out o f both units for 10 minutes.

3. Place the batteries into the remote temperature sensor first then into the

temperature clock.
(All remote temperature sensors must be started before the temperature
clock)

4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.

In this time the temperature clock and remote temperature sensor will start to talk to each
other and the temperature clock will show both the indoor temperature and an outdoor
temperature. If the temperature clock does not display both temperatures after the 10
minutes please retry the set up as stated above. After both indoor and outdoor
temperatures are displayed for 10 minut es you can place your remote temperature sensor
outdoors and set your time.

15

16

B

A

The remote temperature sensor should be placed in a dry, shaded area. The remote
temperature 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 temperature sensor but direct rain must

be avoided.

To complete the set up of your temperature clock after the 10 minutes have passed please
follow the steps below.

Hanging Holes

Function Buttons

Foldout Table Stands

There are two possible ways to mount the temperature clock:

 use of the foldout table stands
 wall mounting

A) FOLDOUT TABLE STANDS

The Foldout table stand legs are located on the
backside, at the lower corners, and on both sides of
the battery cover. The hinges are towards the edges
of the temperature clock and the ends (with no hinge)
need to be folded out towards the edge. Once the
foldout table stands are extended place the
temperature clock in an appropriate location.

B) WALL MOUNTING

1) Using a straightedge, horizontally space at 3-

15/16 of an inch (100.58mm) three screw
positions on a wall.

2) Install three mounting screws (not included) into

a wall within transmission range—leaving
approximately 3/16 of an inch (5mm) extended
from the wall.

3) Place the temperature clock onto the screws, using the hanging holes on the

backside. Gently pull the temperature clock down to lock the screws into
place.

X) THE REMOTE TEMPERATURE SENSOR

The remote temperature sensor can be mounted in two ways

 with the use of screws
 using the adhesive tape

A) MOUNTING WITH SCREWS

1) Remove the mounting bracket from the remote temperature sensor. The

bracket should snap off easily.

2) Place the mounting bracket over the desired location.

3) Through the three screw holes of the bracket, mark the mounting surface

with a pencil.

4) Where marked, start the screw holes into the mounting surface.

5) Screw mounting bracket onto the mounting surface. Ensure that the screws

are flush with the bracket.

6) Snap the remote temperature sensor onto the mounted 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.

3) Adhere the tape to the designated area on the back of the mounting bracket.

4) Remove the protective strip from the other side of the tape.

5) Position the remote temperature sensor in the desired location, ensuring that

the temperature clock can receive the signal.

XI) MAINTENANCE & CARE

 Extreme temperatures, vibrations, and shock should be avoided to prevent

damage to the units.

 Clean displays and units with a soft, damp cloth. Do not use solvents or

scouring agents—they may mark and damage the displays and casings.

 Do not submerge in water.
 Immediately remove all low powered batteries to avoid leakage and damage.

Replace with new batteries only, and of recommended size.

 Opening the casings invalidates the warranty. Do not try to repair the units.
