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

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

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.

Cover

Thermo-Hygro

Sensor

A. Remote Temperature and Humidity Sensor, TX4U

1. Pull the cylindrical rain cover off the sensor.

2. Remove the battery cover (located on the backside of the sensor,

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 sensor.

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.

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

F. Comfort Indicator for Indoor Temperature and Humidity

1. The comfort level indicator appears inbetween the indoor

tempearture and humidity.

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-

8015U averages past air-pressure readings to provide an accurate

forecast—creating a necessity to disregard all weather forecasting for

12-24 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).

ii Sun with Clouds—indicates that the weather is expected to

be fair (not that the weather will be sunny with clouds).

iii Clouds with Rain—indicates that the weather is expected

to get worse (not that 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.

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 30-hours.

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.

VII. MOUNTING

Note: Before permanently mounting, ensure that the indoor weather station is

able to receive signals from the sensors 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/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.

1. Mounting with screws

a. Remove the mounting bracket/receptor from the packaging.

b. Place the mounting bracket over the desired mounting surface.

c. Through the 2 screw holes of the bracket, mark the mounting

surface with a pencil.

d. Where marked, start the screw holes using the provided

screws.

e. Remove screws from the mounting surface.

f. Align the mounting bracket with the started screw holes.

g. Screw mounting bracket onto the mounting surface. The

screws should be flush with the bracket.

h. Fit the mounting post (on the back of the sensor) into the

receptor of the mounting bracket.

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-8015U 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 unfold the

stands on the back and set on a stable flat surface.

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.

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 travels 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 20% or above 95%.

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.
