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 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 WWVB and the atomic clock 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 temperature sensor 3 to 5 apart.  
2. Batteries should be out of both units.  
3. Place the batteries into the remote temperature sensor first then into the  
indoor weather station.  
(All remote temperature sensors must be started before the indoor weather  
station).  
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.  
In this time the indoor weather station and remote temperature sensor will start to talk to each  
other and the indoor weather station will show both the indoor temperature and an outdoor  
temperature. If the indoor 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  
are displayed for 15 minutes you can place your remote temperature 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 80 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 depending upon the type of construction.  
Your distance plus resistance should not exceed 80 ft. in a straight line.  
NOTE: Fog and mist will not harm your remote temperature sensor but direct rain must be  
avoided.  
To complete the set up of your indoor weather station after the 15 minutes have passed please  
follow the steps on pages 8 and 9.  
Note: The remote temperature 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.

VI. TIME  
There are two methods by which the time can be set:  
A) Automatically via WWVB reception or  
B) Manually.  
A. WWVB (Remote Control Time)  
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  
6-10 minutes during optimal conditions. The best conditions 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  
weather 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, will remain steady when the signal has been received and  
nothing will be displayed in all other situations. 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 (once reception has  
occurred the WWVB time will over ride the manual time and set  
automatically).

The WS-9210U is able to receive signals from 3 different remote temperature  
sensors. The remote temperature sensor model(s) that you choose will come with  
14  
 
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 WS-9210U. These extra remote temperature  
sensors can be purchased through the same dealer as this unit, or by contacting La  
Crosse Technology directly. A TX6U will monitor temperature only, a TX3U will  
monitor temperature and display the temperature on its LCD, and the TX3UP will  
monitor the temperature via a probe for measuring soil or water temperatures..  
Note: When setting up multiple units it is important to remove the batteries from all  
existing units in operation. Then insert batteries into all the remote temperature  
sensor units in numeric sequence. Second, install batteries into the indoor weather  
station. Transmission problems will arise if this is not done correctly and if the  
total time for set-up exceeds 6 minutes.  
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 weather 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 and release the “MIN/MAX” 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  
15  
 
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 indoor weather station is able  
to receive WWVB signals from the desired location. Also, extreme and 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. We recommend that you mount  
the remote temperature sensor on a North-facing wall. The sending range is 80ft—  
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 indoor weather  
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.  
Through the three screw holes of the bracket, mark the  
mounting surface with a pencil.  
3) Where marked, start the screw holes into mounting surface.  
4) Screw mounting bracket onto the mounting surface.  
Ensure that the screws are flush with 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.  
16  
 
2) Remove the protective strip from one side of the tape.  
Adhere the tape to the designated area on the back of the  
mounting bracket.  
3) Remove the protective strip from the other side of the tape.  
Position the remote temperature sensor in the desired  
location, ensuring that the indoor temperature station can  
receive the signal.  
II. THE INDOOR TEMPERATURE STATION  
The indoor temperature 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  
1) The indoor temperature 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 temperature 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 temperature station onto the screw using the  
hanging hole on the backside. Gently pull the station down  
to lock the screw into place.
