ABOUT WWVB (Radio Controlled Time)
The NIST (National Institute of Standards and Technology—Time and Frequency Division)
WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact time and date
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 Weather Station. However, due to the
nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The 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 is continually measuring every second, of every day, to an accuracy of ten
billionths of a second per 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 on the atomic clock and 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 thermo station and remote temperature sensor 3 to 5
feet apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote temperature sensor first then into
the thermo station.
(All outdoor remotes must be started before the indoor station)
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the indoor thermo station and remote temperature sensor will start to talk
to each other and the display will show the indoor temperature and an outdoor
temperature. If the indoor thermo station does not display all information after the
15 minutes please retry the set up as stated above. After all information has been
displayed for 15 minutes you can place your sensor outdoors and set your time.
The remote temperature sensor should be placed in a dry, shaded area. The remote
temperature sensor has a range of 330 feet. Any walls that the signal will have to
pass through will reduce distance. An outdoor wall or window can have up to 30
feet of resistance and an interior wall can have up to 20 feet of resistance. Your
distance plus resistance should not exceed 330 ft. in a straight line.
Note: Fog and mist will not harm your remote temperature sensor but direct rain
must be avoided.
Note: The remote temperature sensor transmits a signal every minute. After the
batteries have been installed, the indoor thermo station will search for the signal for
a duration of 15 minutes. If there is no temperature reading in the OUTDOOR LCD
after 15 minutes, make sure the units are within range of each other, or repeat the
battery installation procedure. If a button is pressed before the indoor weather
station receives the temperature signal, you will need to follow the battery
installation procedure again.
To complete the set up of your wireless temperature station after the 15 minutes have
passed please follow the steps that follow in the Detailed Set-Up Guide.

This method requires you to do nothing, except wait for the signal to be
received, and to select a time zone. Reception usually takes
approximately 10 minutes during optimal conditions. The best

10
condition for reception is at night, between midnight and 6:00 am—
when there is less atmospheric interference. To keep your time as
accurate as possible, the thermo station conducts a WWVB search
every night between these hours, and overrides any manually set time.
The WWVB tower icon (appearing in the TIME LCD) will flash when
a signal-search is in progress and a signal is being received, and will
remain steady when the signal has been received. If the WWVB time
has not been received after 10 minutes of battery installation, you may
manually set the time or leave the time function alone (reception will
occur regardless).

VI. ADDING REMOTE TEMPERATURE SENSORS (OPTIONAL)
The TX2000 is able to receive signals from 3 different remote temperature
sensors. The remote temperature sensor model(s) that you choose will
come with their own set of instructions—follow these instructions for a
complete guide to setting up. Following are some brief instructions for the
basic set-up of remote temperature sensor units with the TX2000. These
extra sensors can be purchased through the same dealer as this unit. A
TX6U will monitor temperature only, a TX4U will monitor the temperature
and humidity, a TX3U will monitor temperature and display the
temperature on its LCD, and the TX3UP will monitor the temperature via a
probe for use in pools, spas, etc.
Note: When setting up multiple units it is important to remove the batteries
from all existing units in operation, then to insert batteries first into all the
remote temperature sensor units, and in numeric sequence. Second install
batteries into the thermo station. Transmission problems will arise if this is
not done correctly and if the total time for set-up exceeds 6 minutes.

17
A. SET-UP OF MULTIPLE UNITS
1. It is necessary to remove the batteries from all units currently
in operation.
2. Remove the battery covers to all remote temperature sensor
units.
3. Place all remote temperature sensor units in a numeric
sequential order.
4. In sequential order, install batteries (follow the same battery
installation procedures seen in section I. A) of the Detailed
Set-Up Guide).
5. Install batteries into the indoor thermo station.
6. Follow the Detailed Set-Up Guide for programming and
operating instructions.
B. VIEWING AND OPERATING WITH MULTIPLE
REMOTE TEMPERATURE SENSOR UNITS
1. To view the temperature of a different remote temperature
sensor unit, press and release the CH button. A shift from one
“boxed” number to the next should be observed in the
OUTDOOR LCD.
2. To view the Minimum/Maximum temperature: first select
which remote temperature sensor to read data from (indicated
by the “boxed” number), then press the OUT button. Pressing
this button once will display the minimum temperature, and
the date and time the data was recorded. Pressing this button
a second time (while “MIN” is still displayed, otherwise press
the button twice) will display the same data for the maximum
recordings.
3. To reset the Minimum/Maximum readings, it is necessary to
select which remote temperature sensor you wish to reset.
Press and hold the OUT button for 5 seconds, the records for
the selected remote temperature sensor unit will be reset.
MOUNTING
Note: Before permanently mounting ensure that the thermo station is able
to receive WWVB signals from the desired location. Also, extreme and

18
sudden changes in temperature will decrease the accuracy of the indoor
weather station, and changes in elevation will result with inaccurate
weather forecasting for the next 12 to 24 hours. These changes will require
a 12 to 24 hour wait before obtaining reliable data. To achieve a true
temperature reading, avoid mounting where direct sunlight can reach the
remote temperature sensor or indoor weather station. While the remote
temperature sensor is weather proof, avoid submersion in water or snow.
We recommend that you mount the remote temperature sensor on an
outside North-facing wall. The sending range is 330ft—obstacles such as
walls, concrete, and large metal objects can reduce the range. Place both
units in their desired location, and wait approximately 15 minutes before
permanently mounting to ensure that there is proper reception. The thermo
station should display a temperature in the OUTDOOR LCD within 4
minutes of setting up.
I. THE REMOTE TEMPERATURE SENSOR
The remote temperature sensor can be mounted in two ways:
•with the use of screws, or
•using the adhesive tape.
A. MOUNTING WITH SCREWS
1) Remove the mounting bracket from the remote
temperature sensor.
2) Place the mounting bracket over the desired location.
3) Through 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 temperature sensor into the bracket.
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.

19
4) Remove the protective strip from the other side of the
tape.
5) Position the remote temperature sensor in the desired
location, ensuring that the indoor weather station can
receive the signal.
II. THE INDOOR THERMO STATION
The indoor thermo station can be mounted in two ways:
• with the table stand or,
• on the wall with the use of a wall hanging screw (not
included).
A. USING THE TABLE STAND
The indoor thermo station comes with the table stand
already mounted. If you wish to use the table-stand all
that is required is to place the indoor weather station in
an appropriate location.
B. WALL MOUNTING
1) Remove the table-stand. To do this, pull down on the
stand from the rear and rotate forward.
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 thermo station onto the screw using
the hanging hole on the backside.
4) Gently pull the indoor thermo station down to lock the
screw into place.
TROUBLESHOOTING
NOTE: For problems not solved, please contact La Crosse Technology.
Problem: No reception of WWVB time signal.
Solution: 1) Wait overnight for signal.
2) Be sure indoor thermo station is at least 6 feet from any electrical devices, such
as televisions, computers, or other radio-controlled clocks.
3) Remove batteries for five minutes, reinsert and leave the unit alone overnight
without pressing buttons.
4) If there are still problems, contact La Crosse Technology

20
Problem: Hour is incorrect (minute and date are correct)
Solution: Be sure correct time zone and daylight saving time settings are selected.
Problem: The LCD is faint
Solution: 1) Set the LCD contrast to a higher number
2) Replace the batteries
Problem: No outdoor temperature is displayed.
Solution: 1) Remove all batteries, reinsert into remote temperature sensor first, then into the
indoor thermo station.
2) Place remote temperature sensor closer to the indoor thermo station.
3) Be sure all batteries are fresh.
4) Place remote temperature sensor and indoor thermo station in position so the
straight-line signal is not passing through more than two or three walls.
Problem: Temperatures do not match if units are placed next to each other.
Solution: Each temperature sensor is manufactured to be accurate to within 1 degree plus or
minus and under normal conditions, so two sensors could be as much as 2 degrees
different. However, the difference can be exaggerated further because the sensors
are designed for different working environments. The indoor sensor is less
responsive to ambient air currents because of the shielding effect of the display's
case. In addition, the case can act as a heat sink to absorb and store heat from
external sources (i.e. handling of the case or radiant heat). Also, the much greater
range of the outdoor temperature sensor requires a different calibration curve than
the indoor range. Error is usually greater at the extreme ends of a range, making it
harder to compare different ranges with different curves. Under non-laboratory
conditions, it is difficult to compensate for the above factors and obtain an accurate
comparison.
MAINTENANCE AND CARE INSTRUCTIONS
• Extreme temperatures, vibration, and shock should be avoided to prevent
damage to the units.
• Clean displays and units with a soft, damp cloth. Do not use solvents or
scouring agents; they may mark the displays and casings.
• Do not submerge in water.
• Immediately remove all low powered batteries to avoid leakage and
damage.
• Opening the casings invalidates the warranty. Do not try to repair the unit.
Contact La Crosse Technology for repairs.
