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.

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:  
Waxing Moon Phases  
Waning Moon Phases  
New Moon/High Tide  
Full Moon/High Tide  
Crescent Moon/Medium Tide  
Gibbous/Medium Tide  
First Quarter Moon/Low Tide  
Gibbous/Medium Tide  
Last Quarter Moon/Low Tide  
Crescent Moon/Medium Tide  
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  
11  
 
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)  
Indoor

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  
13  
 
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  
Weather Tendency Arrow  
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.  
,1  
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  
14  
Comfort Level Indicator  
 
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.  
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.  
P„  
A decline in air pressure is  
shown between the “-3” and  
“-1” hours.  
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  
15  
 
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.  
16  
 
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.  
17  
 
VI. RESETTING RAINFALL INFORMATION  
A. RAINFALL QUANTITY TOTALS  
Resetting the Rainfall Quantity Totals will clear the numeric data held  
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.

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 MOON and MIN/MAX buttons.  
“267” (the default rain multiplicator setting) will appear in LCD 1.  
The “7” will be flashing.  
If “267” does not appear, it will be necessary to set the manually  
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).

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.  
19  
 
A. SET-UP OF MULTIPLE SENSORS  
Note: The first sensor signal that the Weather Center receives is  
automatically assigned as the “boxed #1.” The 2nd to be received is the  
“boxed #2,” and the 3rd 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.

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.  
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.  
21  
 
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 surface with the provided screws.  
Ensure that the Rainfall Sensor is completely horizontal and stable.  
1. Rotate the rainfall collector separating it from the base.  
2. 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.  
3. Where marked, start the screws.  
4. Place the base over mounting surface. Install screws through the  
cylindrical holes and into the started holes on the mounting  
surface.  
5. Secure the screws, ensuring that no part of the base can lift off the  
mounting surface.  
6. 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.  
7. 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-7095U—WEATHER CENTER  
1. Using a straightedge, horizontally space at 3 3/16 of an inch  
(81mm) three screw positions on a wall. From the center screw  
position, use the straightedge to vertically mark a fourth screw  
position 20 5/16 of an inch (516mm) down.  
22  
 
2. Install four mounting  
screws (not included)  
into a wall within  
transmission range—  
leaving approximately  
3/16 of an inch (5mm)  
extended from the wall  
for the center screws, and  
11/16 of an inch (18mm)  
extended from the wall  
for the two outer screws.  
3. Place the Weather Center  
onto the screws, using  
the hanging holes on the  
backside. Gently pull the  
Weather Center down to  
lock the screws into place.  
Hanging holes

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.  
Contact La Crosse Technology for Repairs.
