ABOUT WWVB (radio-controlled time)

The NIST (National Institute of Standards and Technology-Time and F requency 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 hav e 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 f or 10 minutes y ou can place your remote thermo/hygro sensor outdoors and set your time.

P.2

The remote thermo/hygro sensor should be placed in a dry, shaded area. The remote thermo/hygro sensor has a range of 200 feet. An y w alls that the signal will hav e to pass through will reduce distance. An outdoor wall or window will have 20 to 30 f eet of resistance and an interior wall will have 10 to 20 feet of resistance. Your distance plus resistance should not exceed 200 ft. in a straight line.

P.3

NOTE

: Fog and mist will not harm your remote thermo/h ygro sensor but direct rain must be avoided.

II. Start Up Sequence

To complete the set up of your indoor weather station after the 10 minutes ha v e 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.

THERMO-SENSOR

433 MHz

Thermo-Hygro Transmitter

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.

2. The indicator will display a "happy-face" when the temperature is between 68˚F and 79˚F (20˚C and 25.9˚C), and the humidity is between 45% and 64%.

3. A "sad-face" will be displayed when the temperature and humidity are outside the mentioned ranges.

4. If the humidity is below 45% the word "DRY" will appear to the right of the "sad-face" icon.

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-8025SU a verages 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.

Sunny

- indicates that the weather is expected to improve (not that the weather

will be sunny).

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. To 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/h ygro sensor is 200 feet(60m) 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.

2. Mounting with Adhesive Tape

a. 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. b. Remove the protective strip from one side of the tape. c. Press firmly onto the designated area on the back of the mounting bracket. d. Remove the protective strip from the other side of the tape, and situate the mounting

bracket. e. Firmly press the mounting bracket onto the mounting surface. f. Fit the mounting post into the receptor of the mounting bracket.

B. Mounting the WS-8025SU Weather Center

The indoor weather station can be mounted in two ways; free standing or hanging on a wall. To have the indoor weather station free standing, simply unf old the stands on the bac k and set

on a stable flat surface.

Maintenance and Care Instructions

A. Extreme temperatures, vibration, and shock should be avoided to prevent damage to the units. B. Clean displays and units with a soft, damp cloth. Do not use solvents or scouring agents; they

may mark the displays and casings.

C. Do not submerge in water. D. Immediately remove all low powered batteries to avoid leakage and damage. E. Opening the casings invalidates the warranty. Do not try to repair the unit. Contact La Crosse

Technology for repairs.

TROUBLESHOOTING

Problem : The LCD is faint. Solution : 1) Set the LCD contrast to a higher level.

2) Replace batteries.

Problem : No outdoor temperature/humidity is displayed. Solution : 1) Remove all batteries, reinsert into the remote thermo/hygro sensor first, then into the

indoor weather station.

2) Place remote thermo/hygro sensor closer to the indoor weather station.

3) Be sure all batteries are fresh.

4) No other interfering sources are being used (such as computer monitors, TV sets, headphones, or speakers) in the vicinity. The signal tra vels in a straight line , an electrical source near that "line" may cause interference.

Problem : Temperature, humidity, or air pressure is incorrect. Solution : 1) Check/Replace batteries.

2) If multiple remote sensors are in use, check location with corresponding "boxed numbers."

3) Move away from sources of heat/cold.

4) Adjust relative air pressure to a value from a reliable source (TV radio, etc.).

5) The indoor weather station and remote sensors are calibrated at the factory. If there is a consistent problem, please call La Crosse Technology.

Problem : "- -" in humidity display. Solution : 1) Humidity is below 1% or above 99%.

2) TX3U or TX3UP is used for remote temperature.

Problem : WWVB time and date will not set or update Solution : 1) Wait until overnight for signal to be received

2) Move indoor weather station away from sources of electricity

3) Place indoor weather station in window facing Colorado

4) The first reception is most difficult, as the indoor weather station needs five continual minutes of clear signal reception. After the initial time/date set, the indoor weather station only requires one full minute of clear reception each night.

To wall mount the indoor weather station;

1. Ensure that the integrated stands are folded in.

2. Fix a screw (not included) into the desired wall, leaving approximately 3/16 of an inch (5mm) extended from the wall.

3. Place the indoor weather station onto the screw using the hanging hole on the backside. Gently pull the indoor weather station down to lock the screw into place.
