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.
GB
P.2
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.
P.3
GB
NOTE
: Fog and mist will not harm your remote thermo/hygro sensor but direct rain must be avoided.
II. Start Up Sequence
T o 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 5 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 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.

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.
Battery
Cover
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.
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.

D. City Location Listing
The following list of city locations is entered in the database. Due the limited memory, 245
cities are listed. Every attempt has been made to provide a location close to all parts of
North America. The choices were based first on state capitals, then nearby locations based
on population and difference of latitude and longitude. There are cases where your city
may be closer to a city in a nearby state rather than your state. We are unable to change
the database, but are open to suggestions for future locations. If you feel there is a city that
should be listed, please write to us (either mail or e-mail).

5. If the humidity is above 54% the word "WET" will appear to the right of the "sad-face" icon.
G. Weather Forecast Icon and Pressure Trend Indicators
The weather forecasting feature is estimated to be 75% accurate, and is based solely upon
the change of air pressure over time. The WS-8025U averages past air-pressure readings to
provide an accurate forecast-creating a necessity to disregard all weather forecasting for 1224 hours after the unit has been set-up, reset, or moved from one altitude to another (i.e. from
one floor of a building to another floor). In areas where the weather is not affected by the
change of air pressure, this feature will be less accurate.

1. Weather Icons
a. There are 3 possible weather icons that will be displayed at various times in the
center of the indoor weather station.
i
Sunny
- indicates that the weather is expected to improve (not that the weather
will be sunny).
ii
Sun with Clouds
weather will be sunny with clouds).
iii
Clouds with Rain
the weather will be rainy).
b. The weather icons change when the unit detects a change in air pressure.
c. The icons change in order, from "sunny" to "sun with clouds" to "clouds with
rain" or the reverse.
d. It will not change from "sunny" directly to "clouds with rain", although it is possible
for the change to occur quickly.
e. If the symbols do not change, the weather has not changed (or the change has
been slow and gradual).
f. The sensitivity of the change in foreacst icon is set by the user in section F of
the Detailed Set Up Guide.
H. Weather Tendency Arrows
Pressure trend arrow
1. Along with the forecast icon there is a pressure tendency arrow.
2. There is one that points up (on the left side of the LCD) and one that points down
(on the right side of the LCD).
3. These arrows reflect current changes in the air pressure.
4. An arrow pointing up indicates that the air pressure is increasing and the weather is
expected to improve or remain good.
5. An arrow pointing down indicates that the air pressure is decreasing and the weather
is expected to become worse or remain poor.
6. No arrow means the pressure is stable.
7. A storm can be expected if there is a drop of 4 hPa or more in less than 6 hours.
The clouds with rain icon will be displayed and the tendency arrow that points down
will be flashing-indicating the storm warning feature has been activated. The flashing
will stop when the air pressure stabilizes or begins to rise.
I. Storm Warning Alarm
1. An alarm can be set to warn of a drop in air pressure.
2. Please follow the programming instructions in section F of the Detailed Set Up
Guide to activate this alarm
3. When the air pressure drops by the level set, an alarm will sound (if the alarm is
activted).
4. To cancel the alarm while sounding press any key.
- indicates that the weather is expected to be fair (not that the
- indicates that the weather is expected to get worse (not that
J.Air Pressure Tendency for Past Two Hours
The bar below the air pressure history chart displays the air pressure change over the past
two hours (values based on hPa change, 1 hPa equals 0.03 inHg).
K. Barometric Air Pressure Reading
1. The actual barometric air pressure is displayed directly under the weather forecast icon
2. The relative air pressure is calibrated by the user through the programming mode.
3. Please Follow the programming instructions in section F of the Detailed Set Up Guide to
set this feature.
4. To toggle between absolute and relative air pressure, press the "-" key.
L. Air Pressure History Bar Chart
1. The bar graph shows in hPa (Hekto Pascal) the recorded air pressure over the past 30hours.
2. The horizontal axis shows the hours at increments of -30 hours, -24 hours, -18 hours, -12
hours, -6 hours, -3 hours, -1 hours, and 0 hours (current).
3. The vertical axis is set by hPa: the "0" on this axis represents the current hPa, and + or
-1,3,5, or 7 shows (in hPa) how high or low the past air pressure was as compared to the
current one.
4. The "0" on the vertical axis indicates the current air pressure value.
5. The "0h" on the horizontal axis indicates the current hour, thus the current air pressure
also.
6. Each bar on the bar graph represents a value of 0.03 hPa, and each bar also has a
corresponding value on the verticle axis.
7. Air pressure trends can be determined by simply glancing at the bar graph.
a. If the bars are rising (higher on the right than the left) then the air pressure has a rising
trend, and the weather should improve.
b. If the bars are dropping (lower on the right than the left) then the air pressure has a
falling trend, and the weather should worsen.
8. Multiply the two values to find past air pressure (note the + or - sign of values on the
verticle axis); i.e. 0.03 hPa x 3 = 0.09 hPa, now add this value to the air pressure (in LCD
4) to evaluate what past air pressures have been.
9. The bar chart will constantly scroll to avoid burnout of the LCD.
Note
: This feature cannot be turned off.
MOUNTING
Note
: Before permanently mounting, ensure that the indoor weather station is able to receive signals
from the transmitters and WWVB signal at the desired location. T o achieve a true temperature reading,
avoid mounting the remote thermo/hygro sensor (or any sensor) where direct sunlight can reach the
remote sensor. We recommend that you mount the remote sensor on a North-facing wall or under an
eve. The sending range of the remote thermo/hygro sensor is 80-ft (25m) however obstacles such as
walls, concrete, and large metal objects can reduce the range. Place all units in their desired location,
and wait approximately 15 minutes before permanently mounting to ensure that there is proper
reception. If the indoor weather station loses the signal from the remote sensor, it will display the last
temperature reading for 15 minutes. After 15 minutes of not receiving any signals, the remote
temperature will display "- -.-".
A. Mounting the Remote Thermo/hygro Sensor
The remote thermo/hygro sensor can be mounted with the use of screws or by using the
adhesive tape.
