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. The Weather Station will search for a si

QUICK SET-UP GUIDE Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries. 1. Have the indoor weather station and remote thermo/hygro sensor 3 to 5 apart. 2. Batteries should be out of both units for 10 minutes. 3. 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) 4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES. In this time the in

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 insta

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 time- date 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. The front two buttons are the “CHANNEL” button (for selecting different remote temperature sensors if added) and the “RESET” button (for resetting the minimu

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. Weather Icons There are 3 possible weather icons that will be displayed in the TENDENCY LCD:

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. 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 impro

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. Minimum and Maximum Temperature Records (Indoor, Outd

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. Note: When setting up multiple units it is important to insert bat

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. To achieve a true temperature reading, avoid mounting
