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 thermo/hygro sensor 3
to 5 apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote thermo/hygro sensor first then
into the indoor weather station.
(All remote thermo/hygro sensors must be started before the indoor
weather station)
4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.
In this time the indoor weather station and remote thermo/hygro 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 and humidity. If the
indoor weather station does not display all values after the 10 minutes please
retry the set up as stated above. After all values are displayed for 10 minutes
you can place your remote thermo/hygro sensor outdoors and set your time.
The remote thermo/hygro sensor should be placed in a dry, shaded area. The
remote thermo/hygro 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 thermo/hygro sensor but direct
rain must be avoided.
To complete the set up of your indoor weather station after the 10
minutes have passed please follow the steps in the Detailed Set Up
Guide.
Note: The remote thermo/hygro 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
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 thermo/hygro sensor first, then the indoor weather station. Initial set
up should be done with the remote thermo/hygro sensor and indoor weather
station in the same room. The units should be permanently mounted only
after the signal reception has been verified.

Battery
Cover
Rain
Cover
A. Remote Temperature and Humidity Sensor, TX4U
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). Press the arrow
and slide the battery cover off.
3. Observing the correct polarity install 2 Alkaline AA batteries.
4. Replace battery cover, and place rain cover snugly onto the
transmitter.
B. Weather Center
1. Remove the battery cover (the cover
has white writing on it).
2. Observe the correct polarity, and
install three Alkaline AA batteries.
3. Do not press any buttons for at least
ten minutes. If a button is pressed
before the Weather Center 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 indoor
weather station will sound a “beep”, and 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 “1.1” as the default date (2001 as the year).
3. “DCA” is the default city (Washington, DC, USA), with the
sunrise, sunset, moonrise and moonset times displayed for that city
at that date.
4. The indoor temperature and humidity, and barometric air pressure
(as 29.91 inHg relative RH) will also be displayed.
5. There is a “satellite” icon that appears near the bottom of the LCD,
to the right of the “max” remote temperature—this icon informs
the user that the indoor weather station is looking for signals from
the remote thermo/hygro sensor. Within five minutes the remote
temperature and humidity 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 Weather Center, 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.

III.
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.
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.

Function Key Layout
A. The below picture shows the eight function keys used in programming
and operation of your indoor weather station
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 and 2 of each programming section.
The programming mode can be exited at any time by either pressing the “CH”
button, or waiting for the 16-second time-out to take effect.
