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 timeout 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 o r sooner. Once the actual date is March 3, you may then reset it. As of this prin ting , no softwar e 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 overloo k the missed programming. Feel free to call or e-mail us with any further questions.

IX. 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 hP a 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 i nH g, “3” hPa= 0.09 inHg, and “4” hPa= 0.12 inHg.

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:

Waxing Moon Phases Waning Moon Phases

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

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)

Current Temperature

Outdoor

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.

The time and date will automatically and simultaneously

Note:

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 maximu m 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—indicates that the weather is expected to improve (no t 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 i n less tha n 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

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-hou rs, 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

P

pressure readings to attain the air pressure 1-hour ago. 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

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 “W EEK,” “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.

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.

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 Rain fall

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 me asurement. There is no need to manually set this number unless it has been changed.

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 ca n be pu r c hased 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 “boxe d #1 .” The 2 “boxed #2,” and the 3

is the “boxed #3.”

to be received is the

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 unde r the “ M IN” 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).

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.

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 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, st art 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-7095 U—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.

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.

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.
