4. Press the SET button to confirm, and to advance to set the Weather
Forecast Sensitivity.
VIII. WEATHER FORECAST SENSITIVITY SETTING
Note: A higher hPa (Hekto Pascal) setting decreases the forecasting
sensitivity of the unit, this feature is available for persons living in areas
where air pressure changes are significant (not necessarily related to a
change of weather). A lower hPa setting is available for areas with a
more constant air pressure. This designates that it takes 2 hPa of
pressure change to change the forecast icon. Note that 1 hPa change =
0.03 inHg (Inch Column of Mercury) change. 1 hPa= 1 mb (millibar).
The hPa options that appear in LCD 4 are “2” hPa= 0.06 inHg, “3”
hPa= 0.09 inHg, and “4” hPa= 0.12 inHg.

Absolute display setting.
IX. DISPLAYING RELATIVE hPa/inHg OR ABSOLUTE hPa/inHg
Note: Air pressure can be displayed in four different measures:
Relative hPa/inHg and Absolute hPa/inHg. Absolute settings give a true
and real-time air pressure reading (at user’s location) that cannot be
manually calibrated. Relative air pressure is measured in relation to sea
level and is the standard meteorological form of measure. Relative air
pressure settings must be manually programmed to suit the users needs.
Relative air pressure can be found from local weather services. Absolute
air pressure decreases by about 0.01 inHg for every 10 feet in altitude.
In higher altitudes (above 6,500 feet), this effect is less noticeable. The
WS-7058U will measure absolute pressure reliably up to 7,500 feet.
There is no limit for relative air pressure since the user sets it.
1. Press the SET button eleven times to reach Relative or Absolute
Display setting mode.

Hold down the OUTDOOR button for 3 seconds. This will reset the
recorded minimum and maximum temperatures for the Outdoor
records.
III. WEATHER FORECAST & WEATHER ICONS
The weather forecasting feature is estimated to be 75% accurate, and is
based solely upon the change of air pressure over time. The WS-7058U
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.

11
A. WEATHER ICONS
There are 3 possible weather icons that will be displayed at various
times in LCD 3:
Sunny—indicates that the weather is expected to improve (not that the
weather will be sunny).
Sun with Clouds—indicates that the weather is expected to be fair (not
that the weather will be sunny with clouds).
Clouds with Rain—indicates that the weather is expected to get worse
(not that the weather will be rainy).
The weather icons change when the unit detects a change in air
pressure. The icons change in order, from “sunny” to “sun with
clouds” to “clouds with rain” or the reverse. It will not change from
“sunny” directly to “clouds with rain”, although it is possible for the
change to occur quickly. If the symbols do not change, the weather has
not changed (or the change has been slow and gradual).
B. WEATHER TENDENCY ARROWS
LCD 3 also displays the
weather tendency arrows.
One arrow points up and one
arrow points down, both arrows appear on the left-hand side of LCD 3
at different times. These arrows reflect current changes in the air
pressure. An arrow pointing up indicates that the air pressure is
increasing and the weather is expected to improve or remain good, and
arrow pointing down indicates that the air pressure is decreasing and
the weather is expected to become worse or remain poor. No arrow
means the pressure is stable.
C. STORM WARNING
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.

D. COMFORT LEVEL INDICATOR
The comfort level indicator appears in the center portion of LCD 2
(between the Indoor temperature and the Indoor humidity) as either a
“happy-face” or as a “sad-face”. 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%. A “sad-face” will
be displayed when the temperature and humidity are outside the
mentioned ranges.
If the humidity is below 45% the word “DRY” will appear to the right
of the “happy-face” icon. If the humidity is above 54% the word “wet”
will appear to the right of the “sad-face” icon.
IV. BAR GRAPH HISTORIES
A. AIR PRESSURE HISTORY
The air pressure is indicated by the appearance of the word
“PRESSURE” at the top of the LCD 4 screen.
The bar graph (in LCD 4) shows in hPa (Hekto Pascal) the recorded air
pressure over the past 48-hours. The horizontal axis shows the hours at
increments of 48-hours, 36-hours, 24-hours, 18-hours, 12-hours,
6-hours, 3-hours, 1-hour, and 0-hours. 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. The “0” on the vertical axis indicates the air
pressure value seen in LCD 5. The “0” on the horizontal axis indicates
that the “0” on the vertical axis is the present air pressure. Each brick
on the bar graph represents a value of 0.03 hPa, and each brick also has
a corresponding value on the verticle axis. 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
Position “0” on both the vertical and horizontal axis indicates present air
pressure. “-1” on the horizontal was 1-hour ago. The top bar corresponds
with “+1” on the vertical axis, multiply 0.03 x (+1) and we get +0.03 hPa.
Add +0.03 to current air pressure readings to attain the air pressure 1-hour
ago. A decline in air pressure is shown between the “-24” and “-3” hours.

13
pressure (in LCD 5) to evaluate what past air pressures have been.
Air pressure trends can be determined by simply glancing at the bar
graph. 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. 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.
A. RAINFALL HISTORY
The bar graph will also display the rainfall history; this mode is
indicated by the appearance of the word “RAIN” at the top-central
position of LCD 4 (see programming mode).
The horizontal axis measures the past time periods, with “0”
representing the current day, and “7” representing 7 days ago. The
graph reads from right to left.
The vertical axis measures the rainfall in either preferred increments of
inches or millimeters. The normal (default) measurement scale is: in
millimeters {0, 1, 3, 5, 10, 30, 50, 100}; in inches {0, 0.1, 0.3, 0.5, 1, 2,
3, 5, 10} . If rainfall exceeds 7 inches (178mm) the measurement scale
automatically changes to: in inches {0, 1, 3, 5, 10, 20, 30, 50, 100}; in
millimeters {0, 10, 30, 50, 100, 300, 500, 1000}.
V. RAINFALL QUANTITY
The rainfall quantities can be displayed 3 different ways, represented by
3 different time period icons, and measured in 2 different units of
measure (inches or millimeters). The quantities are displayed in the
lower portion of LCD 5, and the time period icons appear between the
quantity and the bar graph. Following is a list of the 3 time period icons
and a description of what they represent.
a blank screen—(the default setting) shows the total accumulated rainfall
since the last set-up or manual reset.
“1h”—shows the rainfall measurement of the past hour. Information is
updated every hour on the half-hour (i.e. …at 6:30, at 7:30 and at
8:30…).
“rain icon”—resets automatically at the beginning of a rainfall, it will
show and keep track of the current rainfall quantities, once the current
rainfall is complete it will display the quantity of that rainfall until a new
rain begins, then it will automatically reset.

14
To toggle through the 3 different quantities:
1. Press the RAIN button, the rain icon will appear.
2. Press the RAIN button again, “1h” appears.
3. Press the RAIN button a third time, no icon will be visible.
VI. RESETTING RAINFALL INFORMATION
A. RAINFALL QUANTITY TOTALS
Resetting the Rainfall Quantity Totals will clear the numeric data held
under “TOTAL,” resetting to 0.00 (appearing in LCD 5).
From any selected normal display mode:
1. Press and hold the RAIN button for 3 seconds.
2. Resetting will automatically shift to display “TOTAL.” The
numeric data under “TOTAL” in LCD 5 will read 0.00.
Note: Resetting the Rainfall Quantity Totals does not affect the Rainfall
History represented in the bar graph.
B. MANUAL SETTING OF THE RAIN MULTIPLICATOR
Note: The rain multiplicator is the height of rain held in the
teeter-totter bucket (inside the rain gauge) before it is tipped. It is
preset to a value of 3.75 tips per mm of rain by the manufacturer prior
to shipping; this number produces the most accurate rainfall
measurement. There is no need to manually set this number unless it
has been changed.
1. Remove the batteries and wait 30 seconds. (This will also reset the
Rainfall Quantity Totals).
2. Checking the polarity, install batteries.
3. During the brief 2 seconds that all LCD screens light up,
simultaneously press and hold the RAIN and + buttons.
4. Three numbers will appear in LCD 1 (“375” is the default), with
the last digit “5” flashing.
Note: If “375” is not displayed:
5. Use the +button to change the last digit to a 5 and press the SET
button.
6. Use the +button to change the middle digit to a 7 and press the
SET button.

15
7. Use the +button to change the first digit to a 3 and press the SET
button to enter the normal mode. The Weather Center will enter
into normal operating mode. Do not press any buttons while the
Weather Center searches for transmisssion signals.
8. Follow Program Mode for set-up proceedures.
C. HARD RESET OF EEPROM WEATHER CENTER MEMORY
Note: This is to be used if there are problems with transmission, or if
the rainfall history bar graph needs to be cleared.
1. Remove the batteries and wait 30 seconds. (This will also reset the
Rainfall Quantity Totals).
2. Checking the polarity, install batteries.
3. During the brief 2 seconds that all LCD screens light up,
simultaneously press and hold the RAIN and + buttons.
“375” (the default rain multiplicator setting) will appear in LCD 1.
The “5” will be flashing.
If “375” does not appear, it will be necessary to set the manually
set the digits. Use the + button to change the digit, and the SET
button to select the digit to be changed.
4. Press the SET button two times. (The 3 should flash).
5. Hold the SET button down until the air pressure (in hPa) briefly
flashes in LCD 5. “LCD 5” will flash in LCD 2 for 15 seconds.
6. Do not press any buttons while the Weather Center searches for
transmission signals.
7. Follow Program Mode for set-up proceedures.
VII. ADDING MORE SENSORS (optional)
The WS-7058U can receive signals from up to three Sensors. The
Sensor model(s) that you choose will come with their own set of
instructions—follow those instructions for a complete guide to setting up.
Following are some brief instructions for the basic set-up of additional
sensors with the WS-7058U. Additional sensors can be purchased
through the same dealer as this Weather Center, or by contacting La
Crosse Technology directly (contact information can be found at the end
of this manual). A TX4U will monitor temperature and humidity (it is
the same model that comes with the WS-7058U), a TX3U will monitor
temperature only, and the TX3UP monitors temperature via a 10 foot
probe for use in pools, spas, etc. The TX3 units do not monitor humidity,
thus when they transmit their information to the Weather Center dashes
“- -” appear in the Humidity Display.

16
Note: When setting up multiple sensors it is important to remove the
batteries from all existing units in operation, then to insert batteries first
into all the sensors, and in numeric sequence. Second install batteries
into the Weather Center. 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 SENSORS
Note: The first sensor signal that the Weather Center receives is
automatically assigned as the “boxed #1.” The 2
nd
to be received is the
“boxed #2,” and the 3
rd
is the “boxed #3.”
1. It is necessary to remove the batteries from all units currently in
operation.
2. Remove the battery covers to all sensor units (new and old).
3. Place all sensors in a numeric sequential order.
4. In sequential order, install batteries into the sensors (follow the
same battery installation procedures seen in section I.
5. Install batteries into the Weather Center.
6. Follow the Programming Mode instructions to program and set-up
the Weather Center.
B. SELECTING WHICH SENSOR DATA TO DISPLAY
1. To view the outdoor temperature and humidity from a different
sensor, press the +button. A shift from a “boxed #1” to a “boxed
#2” should be observed under the “MIN” icon in LCD 6.
2. Press the +button a second time to shift from the “boxed #2” to
the “boxed #3”. (Information will display only if you have three
sensors in operation).
3. To view information from the first sensor again, press the +
button.
MOUNTING
Note: Before permanently mounting, ensure that the Weather Center is able to
receive signals from the sensors at the desired location. Extreme and sudden
changes in temperature will decrease the accuracy of the Weather Center, 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
the TX4U—Remote Thermo-Hygro (or any sensor) where direct sunlight can
reach the sensor. We recommend that you mount the sensor on a North-facing
wall. The sending range of the TX4U and the TX5U is 80-ft (25m) however
obstacles such as walls, concrete, and large metal objects can reduce the range.

17
Place all units in their desired location, and wait approximately 15 minutes
before permanently mounting to ensure that there is proper reception. The
Weather Center should display an outdoor temperature in LCD 6 within 5
minutes of setting up. If the Weather Center loses the signal from the sensor, it
will display the last temperature reading for 15 minutes. After 15 minutes of not
receiving any signals, LCD 6 will display “- -.-”. LCD 5 should show “0.0”
within 6 minutes of receiving signals from the TX5U. If the TX5U signal is lost
“--.-” will appear in LCD 5.
I. THE TX4U—REMOTE THERMO-HYGRO SENSOR
The TX4U—Remote Thermo-Hygro Sensor can be mounted in two ways:
•with the use of screws or,
•using the adhesive tape.
A. MOUNTING WITH THE SCREWS
1. Remove the mounting bracket/receptor from the packaging.
2. Place the mounting bracket over the desired mounting surface.
Through the 2 screw holes of the bracket, mark the mounting
surface with a pencil.
3. Where marked, start the screw holes using the provided screws.
Remove screws from the mounting surface.
4. Align the mounting bracket with the started screw holes.
5. Screw mounting bracket onto the mounting surface. The screws
should be flush with the bracket.
6. Fit the mounting post (on the back of the sensor) into the receptor
of the mounting 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. Press firmly
onto the designated area on the back of the mounting bracket.

18
3. Remove the protective strip from the other side of the tape, and
situate the mounting bracket. Firmly press the mounting bracket
onto the mounting surface.
4. Fit the mounting post into the receptor of the mounting bracket.
II) THE TX5U—RAINFALL SENSOR
The Rainfall Sensor can be mounted in two ways:
•Simply placing it in a desired location, or
•Mounting it to a surface with the provided screws.
Ensure that the Rainfall Sensor is completely horizontal and stable.
2) Rotate the rainfall collector separating it from the base.
3) There are two cylindrical holes in the base to guide the mounting
screws. Place the base over a desired mounting surface. With a
pencil, mark the mounting surface through the cylindrical holes.
4) Where marked, start the screws.
5) Place the base over mounting surface. Install screws through the
cylindrical holes and into the started holes on the mounting
surface.
6) Secure the screws, ensuring that no part of the base can lift off the
mounting surface.
7) Remove the manufacture tape from the teeter-totter on the base. If
this is not done there will be no way to measure rainfall, and no
measurement will display on the Weather Center.
8) Place the rainfall collector onto the base. Place the 3 tabs (on the
rainfall collector) into the tab slots (on the base) and turn
counter-clockwise.

III) THE WS-7058U—WEATHER CENTER
The Weather Center can be mounted in 2 ways:
•With the included table stand, or
•By mounting to a wall.
A) TABLE STAND
1) Insert the larger, front tab of the table stand into the receptacle
underneath the Weather Center (if held upright).
2) Push up on the back of the table stand until the two tabs on the
back snap into place.
3) Place the Weather Center in an appropriate location, where
transmission signals can be received.
4) To remove the table stand, pull down on the back until the two tabs
are free from the Weather Center.
B) WALL MOUNTING
1) Remove the table stand.
2) Install a mounting screw (not included) into a wall within
transmission range—leaving approximately 3/16 of an inch (5mm)
extended from the wall.
3) Place the Weather Center onto the screw using the hanging hole on
the backside. Gently pull the Weather Center down to lock the
screw into place.

MAINTENANCE AND CARE
•Extreme temperatures, vibrations, 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 and damage the displays and casings.
•Do not submerge in water.
•Immediately remove all low powered batteries to avoid leakage and
damage. Replace with new batteries only, and of recommended size.
•Opening the casings invalidates the warranty. Do not try to repair the units.
