GENERAL INFORMATION
BATTERIES: WHAT DO I NEED TO KNOW ABOUT BATTERIES?
•Good fresh batteries are important for best performance in your sensors and as backup in
your station.
•Batteries with an expiration date of 2028, were manufactured in 2018.
•We recommend batteries with an expiration date no more than 6 years in advance of the
current year for best performance.
•A minimum voltage of 1.48 v per battery is required for the best performance.
•Lithium batteries may be used in outdoor sensors. Alkaline batteries for the station.
HARDWARE: SENSORS AND STATION
Your V21v3 station comes with:
LTV-W1 or LTV-W2 Wind Speed sensor.
LTV-TH1 Thermo-hygro sensor that reads Temperature and Humidity.
All sensors operate at 915MHz RF.
WHAT ARE THE POWER REQUIREMENTS FOR THIS STATION?
LTV-W1 or LTV-W2:2-C batteries
LTV-TH1: 2-AA batteries
V21v3:5 volt power cord (required) and 3-AA batteries for optional backup of your time and
date. Battery operation only will not update sensor or Wi-Fi data. Power cord is required.
POWER INPUT: WILL THIS STATION WORK IN OTHER COUNTRIES??
•Your power cord input is 100-240V 0.3A 50/60Hz and may work in other countries if the
proper plug adapter is used (not included).
Note: There is no guarantee this station will work in other countries.
•As a standalone station-, you can use this anywhere.
SETUP: HOW DO I SETUP MY STATION?
Your station is a fully functional standalone station.
1. Install batteries into each sensor (any order).

4 | Page
2. Install power cord into wall outlet, and into the station. Install batteries in the station if
you wish.
3. Let sensors and station sit within 10 feet of each other for several minutes to lock the
sensor signals to the display.
Once the sensors are connected, you can choose to connect to the La Crosse View™ app or
continue to use as a standalone station. You can always connect later if you choose. Click
here for instructions for connecting your station to the La Crosse View™ app.
MOUNTING: WHERE DO I MOUNT/POSITION MY SENSORS?
All your sensors read independently to your station. This provides freedom to position each
sensor in the best location available.
LTV-W1 or LTV-W2:
•Place your wind sensor two times higher than any large object within 50 feet. Wind does
not pass through hard objects; it is distorted by them. If your sensor is too close you will
measure the air turbulence and not actual wind speed.
•Place away from trees. Wind passing through trees moves slower than wind in open
areas.
•Mount your sensor in a vertical position with the wind cups on top.
•The maximum transmission distance from your multi-sensor to your station, in open air, is
400 feet (121.92meters).
•Use the included mounting bracket or your own mounting pole (no more than 1 inch
outer diameter to fit). Secure the sensor with screws provided. Tighten the screws to
snug (do not over tighten).
LTV-TH1:
•Place your thermo-hygro sensor at least 6 feet off the ground.
•For accurate temperature readings your sensor needs to be shaded from the sun in a well
vented area.
•Mount your sensor vertically to allow moisture to drain out the bottom.
•The preferred location is on a north facing wall under an eave or deck rail.
•Avoid placing it near a metal roof that will cause it to read high on sunny days.
•Avoid other sources of heat such as soffit vents, and window or door frames.
•For accurate humidity readings, avoid placement near vegetation and lakes or other
bodies of water when possible.
•Place your sensor in a well-vented area. Trapped moisture will cause inaccurate readings.
•Maximum transmission distance from your thermos-hygro sensor to your station, in open
air, is 400 feet (121.92meters).
•Insert the mounting screw through the front of the transmitter and into the wall. Tighten
the screw to snug (do not over tighten).
WHERE TO I PLACE MY STATION?

5 | Page
Your station is designed for flexible placement on a desk or countertop, or to position on the
wall.
•Position within reach of an outlet that is always active. Some outlets in living rooms and
in bedrooms may only be active when the light switch is on.
•This station must operate with the 5 volt power cord in order to receive sensor updates
and/or to update Wi-Fi data when connected. Operation on battery power will only
maintain time/date settings if you need to move your station.
•The best reception occurs when only one wall is between your station and each sensor
outside.
•Position you station six feet from other electronics and wireless devices. If you suspect RF
(radio frequency) interference, simply move your weather station a few feet.
WHAT IS DISTANCE | RESISTANCE | INTERFERENCE?
Distance:
•The maximum transmitting range in open air is over 400 feet (121.92 meters) between
each sensor and your station.
•Consider the signal path from your station to each sensor as a straight line.
•Consider the distance the station is from other electronics in the home.
Resistance:
•Each obstacle: walls, windows, vegetation, stucco, concrete, and large metal objects will
reduce the effective signal range by about one-half.
•Mounting your sensors on a metal fence can significantly reduce the effective signal
range.
Interference:
•Consider electronics in the signal path between the sensors and your station.
•Simple relocation of the sensors or the station may correct an interference issue.
•Windows can reflect the radio signal.
•Metal will absorb the RF (radio frequency) signal.
•Stucco held to the wall by a metal mesh will cause interference.
•Transmitting antennas from: ham radios, emergency dispatch centers, airports, military
bases, etc. may cause interference.
•Electrical wires, utilities, cables, etc. may create interference if too close.
READINGS: HOW DO I INTERPRET THE CURRENT WIND READINGS?
•Wind Speed - is the highest current wind speed at the last record.
•Top Speed – is the highest wind speed reading in the past hour.
Standalone station: When not connected you will see the 24HR wind speed next to the

6 | Page
1HR wind speed.
Connected Station: When station is synced to the La Crosse View™ App, the 24HR wind speed
will forecast Wind Direction.
HOW DO I INTERPRET THE WIND HISTORY READINGS?
In addition to the one hour history which is constantly shown on the station, you can view
wind speed history at 24 hours, 7 days, current month, and current year.
Press and release the WIND button to toggle through the Wind Speed History times.
oOne Hour - Past 60 minute period (default Top Speed record, always shown)
•24 Hour – Shows the top speed in the past 24 hours from the last record. This is a
rolling 24 hour period and not a set midnight to midnight reading.
•7 Days - Shows the top speed in the past 7 days from the last record. This is a rolling 7
day period, not a Monday through Sunday record. Updates at midnight each day.
•Month – Shows top wind speed for the current month. The record is from the first day
of the month to the last day of the month. When in the middle of the month, it will show
the readings from the first day of the month to the last full day. Example: If today is the
15th of the month, the top speed is from the 1st to the 14th. After midnight, the 15th will
be included.
Note: Press and release the PLUS button to view up to 11 previous months.
•Year – Shows top wind speed for the current year. January 1, through December 31st.

FORECAST ICONS: WHAT DO THE FORECAST ICONS MEAN?
Standalone Station: When operating as a standalone station, the forecast icons predict
weather conditions over the next 12-hours based on the change of atmospheric pressure
with about 70-75% accuracy. As weather conditions cannot be 100% correctly forecasted
we are not responsible for any loss caused by an incorrect forecast.
Forecast Icons for standalone station:
•Sunny
•Partly Sunny
•Cloudy
•Rain
•T-Storm
•Snow
Note: The “snow” icon appears when the temperature is below 32°F (0°C) and the forecast
is rainy or stormy.
•Your station calibrates barometric pressure based on its location over time to generate an
accurate, personal forecast. Please allow 7-10 days for barometer calibration.
•IMPORTANT: As the Station builds memory, it will compare the current average
pressure to the past forty day average pressure for increased accuracy. The longer the
Station operates in one location the more accurate the forecast icons will be.
Connected Station: When your station is connected to the La Crosse View™ app you will
see an additional forecast icon from AccuWeather Your forecast will update multiple times
per day. The forecast icons predict weather conditions for the next 3-6 hours.

TROUBLESHOOTING
HOW DO I CHANGE BATTERIES IN MY SENSORS WITHOUT LOSING DATA?
We designed this station for convenience, so that a simple change of batteries does not lose
data or require you to power down your station.
•If you have a low battery icon on your station, you need to replace the batteries in the
sensor or in the station as indicated.
•Simply install fresh batteries into your sensor then hold the SENSOR button for 3 seconds
and your station will search for your sensors.
•When changing the batteries in the station, continue using the power cord. After
replacing the batteries, no other action is needed. The batteries in the station only
maintain time/date in the event of a power outage.
BAR CODE: WHAT ARE THE BARCODES AND ID NUMBERS
ON MY SENSORS AND ON MY STATION?
•Did you know that your sensors will “lock” into your station?
•This ensures that the sensor readings are from your sensor and not a neighbors’.
•When you press and release your SENSOR button you will see your station ID, your
thermo-hygro sensor ID, and your wind speed sensor ID.
•The sensor ID on the station should match your first six numbers on the barcode of that
sensor.
•These sensors will remain locked in your station until you manually delete them.
•The barcodes are also important identifiers for the La Crosse View™ app if you choose to
connect.

14 | Page
HOW DO I DELETE SENSOR ID NUMBERS?
In the rare event you need to replace your sensor, you will first need to delete the old sensor
ID from your station.
1. Remove batteries from your old sensor.
2. Press and release the SENSOR button to view your sensor ID number.
3. While viewing your sensor ID, press the MINUS button for 5 seconds to delete your old
sensor ID. Dashes will show the ID number.
4. Your station will automatically begin searching for the new sensor.
5. Install batteries in your new sensor and allow up to three minutes for your new sensor
readings and ID to appear on your station.
FACTORY RESET: HOW DO I FACTORY RESET MY STATION?
•A factory reset will delete all sensor ID numbers and if connected, remove all Wi-Fi
connections.
•This is a great way to return your station to “out of the box” condition.
•This is more effective than removing all power for clearing out the station.
•All history records will be removed, so write down anything you want to keep.
To factory reset your station:
1. Hold the ALERTS and LIGHT buttons together for 5 seconds.
2. When your station resets it will look for all sensors. Allow at least ten minutes to reacquire
the sensors.
Note: if operating connected, you will need to reconnect to Wi-Fi from the app. Click here
for details.
DASHES TEMP/HUMIDITY: WHY DOES MY THERMO-HYGRO SENSOR SHOW
DASHES ON THE STATION?
Dashes indicate the connection is lost between your station and the outdoor sensor.
•My first thought is always to check that my batteries are good. If it has been working and
now is not, low batteries are the most common connection problem.
•Next, check your distance, resistance and interference. If everything was working
previously at the same location, this is likely not the issue. However sometimes there is
new growth on trees or bushes that causes another barrier. Radio Frequency (RF) signal
does not travel well through foliage due to the moisture content.
•Occasionally adding a new wireless electronic device to the home will cross the signal
path for the sensor. If this occurs try moving your station a few feet or turning the
station 90 degrees for a better angle to receive the sensor signal.

15 | Page
•When you have good batteries, and in a good location, hold the SENSOR button for three
seconds to search for your sensors. If you regain connection while the sensor is
mounted, great. If you do not regain connection, bring the sensor within 10 feet of the
station and search again.
WHY DON’T MY TEMPERATURE/HUMIDITY READINGS
ON MY STATION MATCH THE WEATHER REPORT?
•Your temperature and humidity readings are from your sensor at your location. Your local
reporting station can be miles away so readings will differ.
TEMP ACCURACY: WHY DOES MY THERMO-HYGRO SENSOR READ INCCURATELY?
•The thermo-hygro sensor reads the environment. If your sensor reads high during the
day but not at night it is a mounting problem.
•Side-by-side test: Bring the thermo-hygro sensor in the house and place it next to your
station for 2 hours.
•Compare indoor and outdoor temperature. The temperatures should be within 4 degrees
to be within tolerance. The humidity should be within 14% to be within tolerance.
•If the sensor reads correctly when next to your station then try a different location
outside.
•Look for heat sources such as sunlight, door, or window frames, or reflected heat that
may cause inaccurate readings.
•Press and release the SENSOR button to view the thermos-hygro sensor ID number.
Compare the barcode on your sensor to be sure they match.
•If your temperature is reading low, and location is not an issue, you may have a bad
sensor.
WHAT DOES A READING OF “HI” OR “LO” MEAN?
•If your outdoor temperature reading shows “HI” or “LO”, check that your batteries are
good.
•Overpowered or underpowered batteries can cause this reading.
•If the batteries are good, replace the outdoor sensor.
•If your temperature is fine but your humidity is reading “HI” or “LO” or dashes, your
humidity may be below 10% Relative Humidity. Your sensor does not read below 10%
humidity.
TEMP INTERMITTANT: WHY DOES MY TEMP/HUMIDITY READING COME AND GO?

16 | Page
•RF (radio frequency) communication may come and go occasionally. This can be normal
in some environments (e.g. moister climates).
•If a sensor goes out, please wait 2-4 hours for it to reconnect on its own. Please be
patient – these stations can reconnect on, after many hours out.
•RF (radio frequency) communication is not always 100% on. Certain temporary
conditions can cause it to go out for a time (e.g. 100% humidity).
If a miss happens:
•If the sensor loses connection to the station for any reason, the station will show dashes
after 30 minutes.
•The station will search for 5 minutes every hour to reconnect with sensor.
•Be sure you have good batteries. Manually search for your sensor by holding the SENSOR
button for three seconds.
Try this:
•Bring your sensor within 10 feet of your station and make sure it is connected to the
station.
•After 15 minutes move the sensor into the next room with a wall between the sensor and
the station for 1 hour.
•If there is no loss of signal in that hour, move the sensor just outside.
•Continue moving the sensor back to its original location.
•If you lose connection, look for sources of interference.
WHY AM I GOING THROUGH BATTERIES QUICKLY?
•Test a new set of batteries. Write down the date of installation and the voltage of the
batteries.
•When the batteries fail, please note the date and voltage again. This is helpful in
determining the problem.
•Check for leaking batteries, which may damage the sensor.
HOW DO I CHANGE BETWEEN FAHRENHEIT AND CELSIUS?
•On your sensor, open the battery cover and press the F/C button. This will change the
temperature display on the sensor only.
•On your station enter the program menu to select Fahrenheit or Celsius temperature
display on the station.
WHY ARE MY WIND CUPS NOT SPINNING?
•Check for debris or ice preventing cups from moving.
•Check mounting location. Look for obstructions that prevent the wind from reaching the
sensor.
•In most cases, the wind sensor needs to be 4-6ft above the highest point on the roof to
clear nearby obstructions and read accurately.

•A 50-foot clearance in all directions is best.
•Push down firmly on the center of the cups to reseat them.
•Cups are replaceable.
CAN I REPLACE MY WIND CUPS?
Occasionally, a bad storm with hail or debris that will damage your wind cups. These are
easily replaced.
Replace wind cups:
1. Loosen the screw on side of cups
2. Remove cups
3. Install new cups
4. Tighten screw
Note: The screw in the wind cups will fit on the flat side of the metal stem on the sensor.
WIND READING 0.00: WHY DO I ONLY SEE 0.00 FOR WIND SPEED?
The 0.00 means your wind sensor is connected to your station.
•Check that the cups spin freely. Something may be preventing movement.
•Are your wind cups unbroken? After a storm it is good to check this.
WIND DASHES: WHY ARE THERE DASHES FOR WIND READINGS?
Dashes indicate the connection is lost between your station and the wind sensor.
•My first thought is always to check that my batteries are good. If it has been working and
now is not, low batteries are the most common connection problem.
•Next, check your distance, resistance and interference. If everything was working
previously at the same location, this is likely not the issue. However sometimes there is
new growth on trees or bushes that causes another barrier. Radio Frequency (RF) signal
does not travel well through foliage due to the moisture content.
•Occasionally adding a new wireless electronic device to the home will cross the signal
path for the sensor. If this occurs try moving your station a few feet or turning the
station 90 degrees for a better angle to receive the sensor signal.
•When you have good batteries, and in a good location, hold the SENSOR button for three
seconds to search for your sensors. If you regain connection while the sensor is
mounted, great. If you do not regain connection, bring the sensor within 10 feet of the
station and search again.

WIND INTERMITTANT: WHY DO MY WIND READINGS COME AND GO?
•RF (radio frequency) communication may come and go occasionally. This can be normal
in some environments (e.g. moister climates).
•If a sensor goes out, please wait 2-4 hours for it to reconnect on its own. Please be
patient – these stations can reconnect on, after many hours out.
•RF (radio frequency) communication is not always 100% on. Certain temporary
conditions can cause it to go out for a time (e.g. 100% humidity).
If a miss happens:
•If your wind sensor loses connection to the station for any reason, the station will show
dashes after 30 minutes.
•The station will search for 5 minutes every hour to reconnect with wind sensor.
•Be sure you have good batteries. Manually search for your sensor.
Try this:
•Bring your wind sensor within 10 feet of your station and make sure it is connected to the
station.
•After 15 minutes move the wind sensor into the next room with a wall between the
sensor and the station for 1 hour.
•If there is no loss of signal in that hour, move the wind sensor just outside.
•Continue moving the wind sensor back to its original location.
•If you lose connection, look for sources of interference.
WIND ACCURACY: WHY IS MY WIND SPEED INACCURATE?
•What are you comparing your wind speed to? Your local reporting station is miles from
your location and should not be used for comparison.
•Check the unit of measure (MPH, or KMH).
•Check to see if your station receives the same repetitive wind speed recording from the
sensor multiple times.
•Check that the cups turn freely.
•Check for obstructions that prevent clear wind flow to the cups.
•Check mounting. In most cases, the wind sensor needs to be 6 feet or more above the
highest point on the roof in order to clear nearby obstructions and read accurately. A 50-
foot clearance in all directions is best.
•It is helpful to send pictures of the sensor mounting, if you need to contact customer
support.
