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 Wireless
Weather Stations will search for a signal every night when reception is best.
The WWVB radio station derives its signal from the NIST Atomic clock in
3
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 Wireless Weather Station and remote thermo/hygro sensor 3 to 5 feet
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
Wireless Weather Station.
(All remote thermo/hygro sensors must be started before the Wireless Weather
Station)
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the Wireless Weather Station and remote thermo/hygro sensor will start to talk
to each other and the display will show both the indoor temperature/humidity and an
outdoor temperature/humidity. If the Wireless Weather Station does not display both
temperatures after the 15 minutes please retry the set up as stated above. After both
indoor and outdoor temperatures and humidity are displayed for 15 minutes you can place
your remote thermo/hygro sensor outdoor and set your time.
The remote thermo-hygro sensor should be placed in a dry, shaded area. The thermohygro sensor has a range of 330 feet. Keep in mind that the 330 feet is in open air with no
obstructions and that radio waves DO NOT curve around objects. Actual transmission
range will vary depending on what is in the path of the signal. Each obstruction (roof, walls,
floors, ceilings, thick trees, etc.) will effectively cut signal range in half.
Example: A Wireless Weather Station with a 330 feet range is mounted on an interior wall,
so that the signal has to pass through one interior wall, one exterior wall, and across the 10
feet width of the room between the 2 walls. The first wall will reduce the range to 165 feet,
and the second wall will reduce the range to 87 feet. Factoring in the 10 foot room, this
leaves a maximum of 77 feet of remaining signal range.
This allowance is typically enough for a frame wall with non-metallic siding; however certain
materials can reduce range even further. Metal siding, stucco, and some types of glass
can reduce signal range by as much as ¾ or more, compared to the ½ reduction typical of
most obstructions. It is possible to receive a signal through these materials, however
maximum range will be much less due to their tendency to absorb or reflect a much larger
portion of the sensor’s signal.
DETAILED SET-UP GUIDE
Battery Installation
I.
BATTERY INSTALLATION (When on thermo/hygro sensor is being used)
1. First, insert the batteries to the thermo/hygro sensor (see “A. Remote
Thermo/hygro Sensor” below).
2. Within 2 minutes of powering up the sensor, insert the batteries to the Weather
Station (see “B. Wireless Weather Station” below). Once the batteries are in
4
place, all segments of the LCD will light up briefly. Following the indoor
temperature and humidity, and the time as 12:00 will be displayed. If they are not
shown in LCD after 60 seconds, remove the batteries and wait for at least 60
seconds before reinserting them. Once the indoor data is displayed user may
proceed to the next step.
3. After the batteries are inserted, the Weather Station will start receiving data
signal from the sensor. The outdoor temperature and humidity should then be
displayed on the Weather Station. If this does not happen after 2 minutes, the
batteries will need to be removed from both units and reset from step 1 and the
signal reception icon is no longer shown.
A. Remote Thermo/Hygro 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. Replace the battery cover by sliding upwards. Be
sure battery cover is on securely.
B. Wireless Weather Station
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 indoor weather station has received information
from the TX29UD-TH sensor, no data will be received from that
sensor until reset.
4. Replace the battery cover.
Sensor signal
reception icon*
* When the signal is successfully received by the Weather Station, the icon will
be switched on. (If not successful, the icon will not be shown in LCD) So the user
can easily see whether the last reception was successful (icon on) or not (icon
off). On the other hand, the short blinking of the icon shows that a reception is
being done now.

• If the signal reception is not successful on the first frequency (915MHz) for 45
seconds, the frequency is changed to 920MHz and the learning is tried another
45 seconds. If still not successful the reception is tried for 45 seconds on
910MHz. This will also be done for re-synchronization.
II. Start Up Sequence
A. Initial Start
1. Immediately after the batteries have been installed, the Wireless
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 “SA.1” as the default date (2006 as the year).
3. The indoor temperature and humidity, and barometric air pressure
(as 29.92 inHg) will also be displayed.
4. There is a “satellite” icon that appears in the bottom portion of the
LCD, between the outdoor temperature and humidity — 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 thermo/hygro sensor first, then the Wireless Weather
Station.
B. WWVB Reception
1. Once the batteries are installed in the 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 Wireless 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 recep tion
is not successful within ten minutes, the signal search will be
cancelled and will automatically resume every hour 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 Wireless Weather Station in a
window facing Colorado, at least six feet from any electrical
source (computers, televisions, refrigerators, etc.). Do not move
the Wireless 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 between midnight and 6:00 a.m and
6
correct to the accurate time and date (Daylight Saving Time is
(Up
automatic). If the signal has been received in the past 24 hours, the
reception indicator will be displayed. After a successful reception,
no more reception attempt would be made until the following day.

the values will reset to the current temperature and humidity
and corresponding time.
D. Multiple Remote Temperature Sensors
The WS-8035U-IT is able to receive signals from 2 additional thermo/hygro
sensors. The following are instructions for the set-up of remote thermo/hygro
sensor units with the WS-8035U-IT. These extra sensors can be purchased
through the same dealer as this unit.
1. Remove all the batteries from the receiver and sensor(s) and wait 60
seconds. During these 60 seconds, press any button 20 times to discharge
any excess power.
2. Insert the batteries to the first thermo/hygro sensor.
3. Within 2 minutes of powering up the first sensor, insert the batteries to the
Weather Station. Once the batteries are in place, all segments of the LCD
will light up briefly. Following the indoor temperature and humidity, and the
time as 12:00 will be displayed. If they are not shown in LCD after 60
seconds, remove the batteries and wait for at least 60 seconds before
reinserting them.
4. The outdoor temperature and humidity from the first sensor (channel 1)
should then be displayed on the Weather Station. If this does not happen
and the signal reception icon is not shown, after 2 minutes, the batteries will
need to be removed from both units and reset from step 1.
5. Insert the batteries to the second sensor as soon as the outdoor
temperature and humidity readings from the first sensor are displayed on
the Weather Station.
NOTE: You must insert the batteries into the second sensor within 45
seconds of reception of the first sensor.
6. The outdoor temperature and humidity from the second sensor and the
"channel 2" icon should then be displayed on the Weather Station. If this
does not happen after 2 minute, the batteries will need to be removed from
all the units and reset from step 1.
7. Insert the batteries to the third sensor as soon as the "channel 2" icon and
outdoor data are displayed on the Weather Station. Then within 2 minutes,
the channel 3 outdoor data from the third sensor will be displayed and the
channel icon will shift back to "1" once the third sensor is successfully
received. If this is not happen, user shall restart the setting up from step 1.
15
NOTE: You must insert the batteries into the third sensor within 45
seconds of reception of the second sensor.
IMPORTANT: Transmission problems will arise if the setting for multiple sensors
is not followed as described above. Should transmission problems occur, it is
necessary to remove the batteries from all units and start again the set-up from
step 1.
Viewing and Operating with Multiple Remote Sensors
a. To view the temperature of a different remote sensor press and
release either of the “SNOOZE/CH” buttons. A shift from
one “boxed” number to the next should be observed in the
OUTDOOR LCD.
b. The minimum and maximum temperature of the additional
remote sensor can be displayed by pressing the “OUT/+”
button.
c. To reset the minimum and maximum temper ature rea dings
press and hold the “SET” button for 3 seconds and that
temperature/humidity record for that remote sensor will be
reset only.
Each remote sensor will have its own minimum and maximum values
stored.
E. 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.
F. 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 WS8035U-IT 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.
16
1. Weather Icons
a. There are 3 possible weather icons that will be displayed at
various times in the center of the Wireless Weather Station
i Sunny—indicates that the weath e r 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 th e user
in section F of the Detailed Set Up Guide.
G. Weather Tendency Arrows
1. Along with the forecast icon there
Pressure trend
arrow
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 r emain
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.

H. 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.
I. Air Pressure History Bar Chart
1. The bar graph shows in hPa (Hekto Pascal) the recorded air
pressure over the past 24-hours.
2. The horizontal axis shows the hours at increments of -24 hours, -18
hours, -12 hours, -9 hours, -6 hours, -3 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) ho w hi gh 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 Wireless 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 senso r (or any sensor) where direct sunlight can reach the remote
18
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
330-ft (100m) 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.
The remote thermo/hygro sensor can be mounted in two ways:
• with the use of screws, or
Note: Mounting with adhesive tape is not recommended as a permanent
mounting solution. Only use the adhesive tape during set-up process.
• using the adhesive tape.
A. MOUNTING WITH SCREWS
1) Remove the mounting bracket from the remote
thermo/hygro sensor.
2) Place the mounting bracket over the desired location.
3) Throug h the three screw holes of the bracket, mark the
mounting surface with a pencil.
4) Screw mounting bracket onto the mounting surface.
Ensure that the screws are flush with the bracket.
5) Insert the remote thermo/hygro sensor into the br acket.
B. MOUNTING WITH ADHESIVE TAPE
1) 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.
2) Remove the protective strip from one side of the tape.
3) Adhere the tape to the designated area on the back of
the mounting bracket.
4) Remove the protective strip from the other side of the
tape.
5) Position the remote thermo/hygro sensor in the desired
location, ensuring that the Wireless Weather Station
can receive the signal.
B. Mounting the WS-8035U-IT Wireless Weather Station
The Wireless Weather Station can be mounted in two ways; free
standing or hanging on a wall.
19
To have the Wireless Weather Station free standing, simply unfold the
stands on the back and set on a stable flat surface.
To wall mount the Wireless 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.
4. Gently pull the Wireless 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:
Solution:
The LCD is faint.
1) Set the LCD contrast to a higher level.
2) Replace batteries.
Problem:
Solution:
No outdoor temperature/humidity is displayed.
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 Wireless Weather
Station.
3) Be sure all batteries are fresh.
20
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:
Solution:
Temperature, humidity, or air pressure is incorrect.
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 Wireless Weather Station and remote sensors are calibrated at
the factory. If there is a consistent problem, please call La Crosse
Technology.
Problem:
Solution:
Problem:
Solution:
“- -” in humidity display.
1) Humidity is below 1% or above 99%.
WWVB time and date will not set or update
1) Wait until overnight for signal to be received
2) Move Wireless Weather Station away from sources of electricity
3) Place Wireless 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.
