PROGRAM MODE
The Program Mode is laid out in a manner that allows you to program each
function separately, or you can follow the instructions entirely to program
the Weather Center. Complete programming is usually done for the initial
set-up, and will require you to skip step 1 of each programming section
(from section III to XII). The programming mode can be exited at any time
by either pressing the MIN/MAX button, or waiting for the 20-second time-
out to take effect.
**Important note: Due to a programming error, the WS-7095U will not
properly recognize the dates March 1 or 2. When the date switches from
February 28 (February 29 in leap years), the unit will reset all information to
the default values. Any attempt to set this unit to March 1 or 2 will give the same
result. To prevent this, set the unit to March 3 on February 28 or sooner. Once
the actual date is March 3, you may then reset it. As of this printing, no software
changes are scheduled, and we apologize for that. This product is very
specialized, and volumes do not allow us to easily change the software. We
appreciate your business, and strive to maintain our quality of products. We
hope that you will find this unit has enough good features to help you overlook
the missed programming. Feel free to call or e-mail us with any further
questions.

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.

9
X. 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-7095U 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 twelve times to reach Relative or Absolute
Display setting mode.

FEATURES & OPERATIONS
I. MOON PHASE
The Moon Phases, and their corresponding dates and tide levels, appear
in LCD 2. While viewing LCD 2 in the normal display mode, the current
moon phase, corresponding tide level, and current date are all displayed.
There are 8 visible Moon Phases that will show in the LCD:
The Weather Center is programmed with all moon phases, corresponding
dates, and the tide levels from the year 1998 until 2020.
1. To enter the Moon Phase mode from the normal display mode,
press the MOON button.
2. Now showing in LCD 2 is the current moon phase, corresponding
tide level, and the date that this moon phase began (keep in mind
that if your current moon phase began on the current date, there
will be no change in date).
Note: The date display (month/date/year or weekday/month/day) is
determined by the date display setting that you entered in section
VII of the Programming Mode.
While still in the Moon Phase:
3. Press the MOON button a second time. Now appearing in LCD 2
is the current moon phase and the subsequent date at which the
current moon phase will be entered into again. Repeating this will
continue to show subsequent dates until the year 2020, then the
information will wrap around and begin to display information
starting from the year 1998.
4. Press the CH/+ button. LCD 2 now shows the next moon phase
and the date it begins. Continue to press the CH/+ button to show

every moon phase and its beginning dates until the year 2020
(wrapping around to 1998).
Note: The Moon Phase features allow for the discovery of dates of
specific moon phases. Hypothetically, if the date of the next full
moon were desired (and the current moon phase was not a full
moon), simply press the MOON button, press the CH/+ button
repeatedly until you reach a full moon display in LCD 2—the date
of the next full moon would be displayed. Press the CH/+ button
repeatedly and the dates of all full moons until the year 2020 will
sequentially appear.
II. MINIMUM & MAXIMUM TEMPERATURES
A. DISPLAYS AND FUNCTIONS
The Weather Center automatically stores the minimum and maximum
temperatures, and the time and date of their occurrence. In either
LCD 3 or LCD 6 (Indoor and Outdoor respectively) the minimum
temperature appears on the left side of the screen and is marked by the
“MIN” (minimum) icon, while the maximum temperature appears on
the right side of the screen and is marked by the “MAX” (maximum)
icon. The “MIN” temperatures are rounded down, and the “MAX”
temperatures are rounded up—no matter what the decimal values are.
To view the times and dates these temperatures were recorded, follow
the below procedures.
1. Press the MIN/MAX button. The Current Indoor temperature in
LCD 3 shifts to a flashing display of the minimum recorded indoor
temperature, the smaller “MIN” temperature also flashes. The
recorded time simultaneously displays in LCD 1, and the date
simultaneously displays in LCD 2.

Note: The time and date will automatically and simultaneously
appear in their respective LCD’s for all following steps in this
section.
2. Press the MIN/MAX button a second time. The flashing minimum
temperature in LCD 3 shifts to flash the recorded maximum
temperature.
3. Press the MIN/MAX button a third time. In LCD 6 the Current
Outdoor temperature shifts to a flashing display of the minimum
recorded outdoor temperature.
4. Press the MIN/MAX button a fourth time. The flashing minimum
temperature in LCD 6 shifts to flash the recorded maximum
temperature.
5. Press the MIN/MAX a final time and the LCD’s return to normal
display mode.
B. RESETTING THE MINIMUM & MAXIMUM RECORDS
Hold down the MIN/MAX button for 3 seconds. This will reset all
recorded minimum and maximum temperatures for both the Indoor and
Outdoor records. The “MIN” and “MAX” displays will show the
rounded figures for the current temperature.
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-7095U
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.
A. WEATHER ICONS
There are 3 possible weather icons that will be displayed at various
times in LCD 4:
Sunny
Sun with Clouds
Clouds with Rain

14
,1
Comfort Level Indicator
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 syumbols do not change, the weather has not changed (or the change
has been slow and gradual).
B. WEATHER TENDENCY ARROWS
LCD 4 also displays the weather
tendency arrows. 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).
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
lower portion of LCD 3 as either a
“happy-face” to the left of the indoor
humidity, or as a “sad-face” to the right of
Weather Tendency Ar
row

15
the indoor humidity. 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 “sad-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 5 screen.
The bar graph (in LCD 5) shows in hPa (Hekto Pascal) the recorded air
pressure over the past 24-hours. The horizontal axis shows the hours at
increments of 24-hours, 18-hours, 12-hours, 6-hours, 3-hours, 2-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 4. 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 pressure
(in LCD 4) 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
P
Position “0” on both the
vertical and horizontal
indicate 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, 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 “-3” and
“-1” hours.

16
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.
B. 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 of the
LCD 5 screen.
The horizontal axis measures the past time periods, with “0”
representing the current day, week, or month and “7” representing the
oldest information (7 days ago, 7 weeks ago, or 7 months 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
inches {0, 0.1, 0.3, 0.5, 1, 2, 3, 5, 10}; in millimeters {0, 1, 3, 5, 10, 30,
50, 100}. If, within any selected time period (1 day, 1 week, 1 month),
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}.
The bar graph will display the rainfall history either by day, week, or
month. To select which display:
1. Press the RAIN button twice. The “DAY” icon will flash beside
the “RAIN” icon at the top of LCD 5.
2. Press the CH/+ button to toggle through the “WEEK,” “MONTH,”
and “DAY” icons.
3. Press the RAIN button (or wait 20 seconds) to confirm and exit this
selection mode.
If “DAY” is selected, the graph will display the rainfall history for
the past 7 days. The information that is displayed in column “0”
(the right column) is renewed daily at midnight, and the
information contained in the columns is shifted to the left. If
“WEEK” is selected, the graph will display the rainfall history for
the past 7 weeks. The information that is displayed in column “0”
is renewed every Monday at midnight, and the information
contained in the columns is shifted to the left. If “MONTH” is
selected, the graph will display the rainfall history for the past 7
months. The information displayed in column “0” is renewed on
the first day of every month, at minight. The information
contained in the columns is shifted to the left.

17
The bar graph displays the columns sequentially from “0” to “7”
until all columns are showing. Then they are hidden again, and the
sequential display is repeated. It is possible to read each column,
one at a time—simultaneously displaying the numeric
measurement for that column directly under the bar graph. To do
this:
1. Press the RAIN button twice, either “DAY,” “WEEK,” or
“MONTH” should flash to the left of the “RAIN” icon.
2. Press the SET button, column “0” will flash, and the rainfall
measurement value is displayed directly under the bar graph.
3. Press the CH/+ button to toggle through columns “0” to “7.”
4. While column “7” is flashing press the CH/+ button to exit this
mode.
V. RAINFALL QUANTITY
The rainfall quantities can be displayed 4 different ways, represented by
4 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.
1. While in normal viewing mode, press the “RAIN” key once. The
current selected period will flash (“TOTAL”, “1H, “24H”, or the
rain icon).
2. Press the “+” key to toggle through the selections. Following is a
list of the 4 time period icons and a description of what they
represent.
“TOTAL”—(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…).
“24h”—shows the measured rainfall of the last 24-hour period.
Updates are made daily at 7:00 am.
“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.
3. Press the “RAIN” key twice to exit this mode, or do not press any
buttons for 20 seconds.

18
VI. RESETTING RAINFALL INFORMATION
A. RAINFALL QUANTITY TOTALS

under “TOTAL,” “1h,” and “24h,” resetting all 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 0.267mm 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.

set the digits. Use the CH/+ button to change the digit, and the
SET button to select the digit to be changed.
4. Press the SET button two times. (The 2 should flash).
5. Hold the SET button down until the air pressure (in hPa) briefly
flashes in LCD 4. “LCD 7” 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 procedures.
VII. ADDING MORE SENSORS (optional)
The WS-7095U 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-7095U. 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-7095U), 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.
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 min.

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. A).
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 CH/+ button. A shift from a “boxed #1” to a
“boxed #2” should be observed under the “MIN” icon in LCD 6.
2. Press the CH/+ 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 CH/+
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.
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.
