ABOUT WWVB (radio-controlled time)

The NIST (National Institute of Standards and Technology—Time and

Frequency Division) radio station, WWVB, 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 indoor weather station. However, due to the nature of the Earth’s

Ionosphere, reception is very limited during daylight hours. The indoor 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 continually measure every second of

every day to an accuracy of ten billionths of a second a 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 weather station and remote temperature sensor 3

to 5 apart.

2. Batteries should be out of both units for 15 minutes.

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

into the indoor weather station.

(All remote temperature sensors must be started before the indoor

weather station)

4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.

In this time the indoor weather station and remote temperature sensor will start

to talk to each other and the indoor weather station will show both the indoor

temperature and humidity and the outdoor temperature. If the indoor weather

station does not display all values after the 15 minutes please retry the set up as

stated above. After all values 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

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 300 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 indoor weather station after the 15

minutes have passed please follow the steps in the Detailed Set Up

Guide.

Note: The remote temperature sensor transmits a signal every 3 minutes; after

the batteries have been installed, the indoor 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

Batteries will fit tightly. To avoid start-up problems, make sure that the

batteries do not spring free. Also be sure to insert alkaline batteries into the

remote temperature sensor first, then the indoor weather station. Initial set

up should be done with the remote temperature sensor and indoor weather

station in the same room. The units should be permanently mounted only

after the signal reception has been verified.

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. 4. Replace the battery cover by sliding

upwards. Be sure battery cover is on securely.

B. Indoor Weather Station

1. Remove the battery

cover (the cover has

white writing on it).

2. Observe the correct

polarity, and install

two Alkaline AA

batteries.

3. Do not press any

buttons for at least

ten minutes. If a

button is pressed

before the indoor

weather station has

received information

from the TX4U

sensor, no data will

be received from that

sensor until reset.

4. Replace the battery

cover.

II. Start Up Sequence

A. Initial Start

1. Immediately after the batteries have been installed the LCD will

completely light up for a brief moment.

2. All information will then appear in normal mode, with “12:00” as

the default time and “WE.1” as the default date (2004 as the year).

3. The indoor temperature and humidity, and barometric air pressure

(as 29.91 inHg relative RH) will also be displayed.

4. There is a “satellite” icon that appears in the bottom portion of the

LCD, to the left of the outdoor temperature— this icon informs the

user that the indoor weather station is looking for signals from the

remote temperature sensor. Within five minutes the remote

temperature should be displayed—if not, remove batteries from all

units and repeat battery installation, the remote temperature sensor

first, then the indoor weather station.

B. WWVB Reception

1. Once the batteries are installed in the indoor weather station it will

automatically search for the WWVB signal. If it receives a good

signal (which is unlikely during daylight hours in most locations),

the WWVB reception indicator (looks like a tower icon) will flash.

The indoor weather station requires five full minutes of good

reception to successfully capture the signal and set to the correct

hour, minute, second, month, day and year. If the signal reception

is not successful within ten minutes, the signal search will be

cancelled and will automatically resume every two hours until the

signal is successfully captured.

2. The signal is sent from Ft. Collins, Colorado only and is similar to

an AM radio signal. Atmospheric interferences such as storms,

sunspots, and even sunlight will cause the signal to not travel as

far.

3. To maximize reception, place the indoor weather station in a

window facing Colorado, at least six feet from any electrical

source (computers, televisions, refrigerators, etc.). Do not move

the indoor weather station while it is searching for the signal.

4. The time and date can be manually set. Once the signal is captured,

it will override any time and date set to the time zone selected.

5. Once the time and date are set, the indoor weather station will

conduct a search every night at midnight and correct to the

accurate time and date (Daylight Saving Time is automatic). If the

signal has been received in the past 24 hours, the reception

indicator will be displayed.

III. Explanation of LCD Information

A. The below picture highlights the LCD features.

B. There are many different modes the indoor weather station can be set

to. The LCD shown is the normal operating mode, and your actual data

shown will be different based on your local settings and conditions.

IV. Function Key Layout

A. The below picture shows the four function keys used in programming

and operation of your indoor weather station

V. Program Mode

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

indoor weather center. Complete programming is usually done for the initial

set-up, and will require you to skip step 1,2 and 3 of each programming section.

The programming mode can be exited at any time by either pressing the “CH”

button, or waiting for the 15-second time-out to take effect.
