ABOUT WWVB The NIST (National Institute of Standards and Technology—Time and Frequency Division) radio station, WWVB, is located in Ft. Collins, Colorado and transmits the exact time signal continuously throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna in the Weather Station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours.
QUICK SET-UP GUIDE Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries. 1. 2. 3. 4. Have the indoor weather station and remote thermo/hygro sensor 3 to 5 apart. Batteries should be out of both units for 10 minutes. Place the batteries into the remote thermo/hygro sensor first then into the indoor weather station. (All remote thermo/hygro sensors must be started before the indoor weather station) DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.
To complete the set up of your indoor weather station after the 10 minutes have passed please follow the steps in the Detailed Set Up Guide . Note: The remote thermo/hygro sensor transmits a signal every 3 minutes; after the batteries have been installed, the indoor weather station will search for the signal for a duration of 5 minutes. If there is no temperature reading in the OUTDOOR LCD after 5 minutes, make sure the units are within range of each other, or repeat the battery installation procedure.
DETAILED SET-UP GUIDE BATTERY INSTALLATION A. Remote Thermo/hygro Sensor 1. Pull the cylindrical rain cover off the remote thermo/hygro sensor. 2. Remove the battery cover (located on the backside of the remote thermo/hygro sensor, above the mounting post and bracket). 3. Press the arrow and slide the battery cover off. 4. Observing the correct polarity install 2 AA batteries. 5. Replace battery cover, and place rain cover snugly onto the remote thermo/hygro sensor. B. Indoor Weather Station 1.
is achieved easiest at night), it will display the correct time (factory setting is Eastern time zone). PROGRAM MODE Programming Note: If 20 seconds is allowed to pass during programming modes, the unit will confirm/set the last information entered—the display will stop flashing and return to normal timedate readings TIME AND DATE There are two methods by which the time and date can be set: 1) Automatically via WWVB reception (only need to set the time zone in section III).
2) Manually (performed throughout the programming mode. When programming, the manual setting of time and date is not necessary and can be skipped. Any time information programmed will be over-written by the reception of the WWVB signal. FUNCTION KEYS There are four buttons on the WS-7391U, two on the front and two on the back.
II. Time Setting Note: This is only necessary if you do not wish to wait for the WWVB reception. All manual set data will be over-ridden by the reception of the WWVB signal based on the time zone selected. 1. 2. 3. Press and hold the “SET” button (on the back of the clock) for 2 seconds or until “12h” or “24h” flashes. Press and release the “SET” button again, the hour will flash. Press and release the “+” button to advance the hour.
3. Press and release the “+” button to select your desired time zone. The TIME LCD displays the 3 letter abbreviations for the time zones found in North America. Observe the chart below, showing corresponding abbreviations, time zones, and codes. Display GMT AST EST; CST; MST; PST; ALA; HAW; 4.
Note: Some locations (Arizona and parts of Indiana) do not follow Daylight Saving Time. 5. Press and release the “SET” button to confirm and advance to the Date setting mode (skip step 1and 2 in section V if continuing). V. Setting the Day, Date and Year Note: This is only necessary if you do not wish to wait for the WWVB reception. All manual set data will be over-ridden by the reception of the WWVB signal based on the time zone selected. 1.
11. Press and release the “SET” button to confirm the year and to advance to °F and °C selection (skip step 1 and 2 in section VI if continuing). VI. Selecting °F OR °C 1. 2. 3. 4. 5. Press and hold the “SET” button for 2 seconds or until “12h” or “24h” flashes. Press and release the “SET” button 9 times to reach the °F or °C setting mode. “°F” is the default setting and the temperatures (inside and remote) will be flashing. Press and release the “+” button to select °F to °C.
FEATURES OF THE WS-7391U I. Weather Forecast The weather forecasting feature is estimated to be 75% accurate. By adjusting the sensitivity setting, you can achieve a better accuracy of forecast. The weather forecast is based solely upon the change of air pressure over time. In areas where the weather is not affected by the change of air pressure, this feature will be less accurate. 1.
then the weather has not changed or the change has been slow and gradual. If this happens on a regular basis, it may be necessary to adjust the weather forecast sensitivity. 2. Weather Tendency Arrows Other possible displays in the TENDENCY LCD are 2 weather tendency arrows, one that points up and one that points down.
III. Outdoor Temperature and Humidity The outdoor temperature and humidity is viewed in the OUTDOOR LCD. When there is more than one remote sensor unit in operation a “boxed” number will appear to the right of the temperature. This indicates which remote sensor unit (1, 2, or 3) is currently displaying its data in the OUTDOOR LCD. (This feature is explained in further detail in the following section—Adding Remote Sensors). IV.
V. Adding Additional Remote Sensors (Optional) The WS-7391U is able to receive signals from 3 different remote sensors. These extra remote sensors can be purchased through the same dealer as this unit. A TX4U will monitor the temperature and humidity, a TX3U will monitor temperature and display the temperature on its LCD and the TX3UP will monitor the temperature via a probe for measuring soil or water temperatures.
VII. Viewing and Operating with Multiple Remote Sensors 1. 2. 3. To view the temperature of a different remote sensor press and release the “CHANNEL” button. A shift from one “boxed” number to the next should be observed in the OUTDOOR LCD. The minimum and maximum temperature of the additional remote sensor will be displayed below the current temperature of the remote sensor in the OUTDOOR LCD.
VIII. Mounting Note: Before permanently mounting ensure that the indoor weather station is able to receive WWVB signals from the desired location. Also, extreme and sudden changes in temperature will decrease the accuracy of the indoor weather station. 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.
5. Remove screws from the mounting surface. 6. Align the mounting bracket with the started screw holes. 7. Screw mounting bracket onto the mounting surface. The screws should be flush with the bracket. 8. Fit the mounting post (on the back of the remote thermo/hygro 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.
2. The Indoor Weather Station 1. The WS-7391U is a wall mount only indoor weather station. To mount the display on your wall: 2. Fix a screw (not included) into the desired wall, leaving approximately 3/16 of an inch (5mm) extended from the wall. 3. Place the indoor weather station onto the screw using the hanging hole on the backside. 4. Gently pull the indoor weather station down to lock the screw into place.
Troubleshooting Problem: Solution: Problem: Solution: Problem: Solution: Problem: Solution: Problem: Solution: No reception of WWVB time signal 1) Wait overnight for signal. 2) Be sure indoor weather station is at least 6 feet from any electrical devices, such as televisions, computers, or other radio-controlled clocks. 3) Remove batteries for five minutes, reinsert and leave alone without pressing buttons overnight.
Maintenance and Care Instructions • • • • • Extreme temperatures, vibration, 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 the displays and casings. Do not submerge in water. Immediately remove all low powered batteries to avoid leakage and damage. Opening the casings invalidates the warranty. Do not try to repair the unit. Contact La Crosse Technology for repairs.
