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

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 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 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.

DETAILED SET-UP GUIDE

I) BATTERY INSTALLATION

Note: To avoid start-up problems make sure that the batteries do not spring free.

A) REMOTE TEMPERATURE TRANSMITTER

1) Remove the battery cover. Place your thumb over

the two air-vent slots on the face of the remote

temperature sensor, push down gently, and slide

battery cover down and off.

attery

Cover

2) Observing the correct polarity, install 2 AA batteries.

The batteries will fit tightly (to avoid start-up

problems make sure that they do not spring free

during installation).

3) Replace the battery cover.

B) TEMPERATURE CLOCK

1) Remove the battery cover,

located on the backside of the

temperature clock and directly

below the function buttons.

2) Observe the correct polarity,

and install 2 AA batteries.

3) Replace the battery cover.

Note: After the batteries have been installed a tone will sound, and all the LCD’s

(Liquid Crystal Display) will briefly light up. The indoor temperature, the date as

“1/ 1”, the weekday as “MON”,

and the remote temperature will

be displayed (within three

minutes). Also, the time will

appear as “-:--” for

approximately 1 minute. The

WWVB search is automatically

initiated, and a tower icon

appears and flashes with the time colon (no tower icon will appear if the WWVB is

too weak to be detected, and the time display will remain on “-:--”). While the

WWVB search is being conducted various numbers will appear in the time display.

Within 10 minutes the temperature clock will either display the WWVB time, or

discontinue the search if the time is not found. If the search is cancelled “-:--” will

appear in the time LCD. The temperature clock will conduct a WWVB search every

hour until the first signal is found. Once the WWVB time is found, a search is

automatically conducted nightly at midnight. If the signal is found at midnight, the

tower icon will remain, if not, another search will take place every hour (until 6:00

am) until the signal is found successfully. If no signal is found during this period,

the tower icon will not appear and the clock will search again at 12:00 am the next

night.

II) PROGRAM MODE

To enter the Program Mode hold down the “SET” button for 2 seconds, until

“-5EST” flashes in the Date LCD. The Program Mode is laid out in a manner that

allows you to program each function separately, or you can follow the instructions

entirely to program the temperature clock. Complete programming is usually done

for the initial set-up, and will require you to skip step 1 of programming sections C

through H. Press and release the “SNOOZE” button at any time to exit the Program

Mode, or wait approximately 15 seconds for the temperature clock to automatically

return to normal operation.

A) FUNCTION BUTTONS

There are 4 function buttons located on the backside of the temperature clock.

The function buttons are labeled: “SET”, “+”, “ALARM”, and “SNOOZE”.

B) TIME ZONE SETTING

1) Hold down the “SET” button for 2 seconds, the default (factory) setting

“-5EST” will flash in the Date LCD.
