INVENTORY OF CONTENTS 1. WS-7394U—indoor weather station 2. TX6U—remote temperature (temperature/humidity) sensor 3. Instruction manual and warranty card ADDITIONAL EQUIPMENT (not included) 1. Five fresh AA 1.5V alkaline batteries. 2. One wall-mounting screw (optional) ABOUT WWVB (radio-controlled time) The NIST (National Institute of Standards and Technology—Time and Frequency Division) radio station, WWVB, is located in Ft.
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 temperature sensor 3 to 5 apart. Batteries should be out of both units for 15 minutes. Place the batteries into the remote temperature sensor first then into the indoor weather station. (All remote temperature sensors must be started before the indoor weather station) DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
DETAILED SET-UP GUIDE I. Battery Installation Batteries will fit tightly. To avoid start-up problems, make sure that the batteries do not spring free. Also be sure to insert alkaline batteries into the remote temperature sensor first, then the indoor weather station. Initial set up should be done with the remote temperature sensor and indoor weather station in the same room. The units should be permanently mounted only after the signal reception has been verified. A.
II. Start Up Sequence A. Initial Start 1. Immediately after the batteries have been installed the LCD will completely light up for a brief moment. 2. All information will then appear in normal mode, with “12:00” as the default time and “WE.1” as the default date (2004 as the year). 3. The indoor temperature and humidity, and barometric air pressure (as 29.91 inHg relative RH) will also be displayed. 4.
III. Explanation of LCD Information A. The below picture highlights the LCD features. Radio-controlled time WWVB Reception Indicator Date Display Comfort Icon Indoor Temperature Humidity Display Air Pressure Trend Indicator Forecast Icon Barometric Air Pressure 12-hour Air Pressure History Outdoor Temperature Display Remote Sensor Number (Up to 3 Total) B. There are many different modes the indoor weather station can be set to.
IV. Function Key Layout A. The below picture shows the four function keys used in programming and operation of your indoor weather station V. 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 indoor weather center. Complete programming is usually done for the initial set-up, and will require you to skip step 1,2 and 3 of each programming section.
C. Time Zone Setting 1. Press and hold the “SET” button for five seconds. 2. “lcd” will appear at the top of the display and a number will flash next to it. 3. Press and release the “SET” button once more to advance to the Time Zone setting. 4. A number will flash to the left of the letter “h” at the top of the display just below the time display. 5. Press and release the “OUT+” button to select the desired time zone. 6.
6. Press and release the “SET” button to confirm the Radiocontrolled time ON/OFF setting and continue to the 12/24-hour Time Mode setting. F. 12/24-hour Time Mode 1. Press and hold the “SET” button for five seconds. 2. “lcd” will appear at the top of the display and a number will flash next to it. 3. Press and release the “SET” button four more times to advance to the 12/24hour time mode setting. 4. “12h” or “24h” will flash above the indoor temperature/humidity display. 5.
4. 5. The minutes will begin to flash at the top of the display. Press and release the “OUT/+” button to select the desired minutes. 6. Press and release the “SET” button to confirm the minutes and continue to the Year setting. I. Setting The Year Manually 1. Press and hold the “SET” button for five seconds. 2. “lcd” will appear at the top of the display and a number will flash next to it. 3. Press and release the “SET” button seven more times to advance to the Manual Year setting. 4.
L. Temperature Measuring Units Selection (°F or °C) 1. Press and hold the “SET” button for five seconds. 2. “lcd” will appear at the top of the display and a number will flash next to it. 3. Press and release the “SET” button ten more times to advance to the Temperature Measuring Units setting. 4. °F or °C will flash at the top of the display. 5. Press and release the “OUT/+” button to select the desired temperature-measuring unit. 6.
O. Forecast Sensitivity Setting 1. Press and hold the “SET” button for five seconds. 2. “lcd” will appear at the top of the display and a number will flash next to it. 3. Press and release the “SET” button thirteen more times to advance to the Forecast sensitivity setting. 4. The two air pressure tendency arrows will begin flashing on either side of the forecast icon and a flashing number will appear under the forecast icon. 5.
FEATURES AND OPERATIONS A. Minimum and Maximum Temperature and Humidity 1. Indoor Minimum and Maximum Temperature and Humidity The indoor weather station automatically stores the minimum and maximum indoor temperature and humidity. The minimum and maximum values are updated automatically when a new minimum or maximum is recorded, or until manually reset. a. b. c.
Next press and hold the “SET” key for at least three seconds. You will see then that the values will reset to the current temperature and corresponding time. B. Multiple Remote Temperature Sensors The WS-7394U is able to receive signals from 3 different remote sensors. These extra remote sensors can be purchased through the same dealer as this unit.
Each remote sensor will have its own minimum and maximum values stored. C. Comfort Indicator for Indoor Temperature and Humidity 1. 2. 3. The comfort level indicator appears inbetween the indoor tempearture and 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. D.
e. f. If the symbols do not change, the weather has not changed (or the change has been slow and gradual). The sensitivity of the change in foreacst icon is set by the user in section F of the Detailed Set Up Guide. E. Weather Tendency Arrows Pressure trend 1. 2. 3. 4. 5. 6. 7. arrow Along with the forecast icon there is a pressure tendency arrow. 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).
5. 6. 7. 8. 9. The “0h” on the horizontal axis indicates the current hour, thus the current air pressure also. Each bar on the bar graph represents a value of 0.03 hPa, and each bar also has a corresponding value on the verticle axis. Air pressure trends can be determined by simply glancing at the bar graph. a. 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. b.
VII. MOUNTING Note: Before permanently mounting, ensure that the indoor weather station is able to receive signals from the sensors and WWVB signal at the desired location. To achieve a true temperature reading, avoid mounting the remote temperature sensor (or any sensor) where direct sunlight can reach the remote sensor. We recommend that you mount the remote sensor on a North-facing wall or under an eve.
B. Mounting the WS-7394U Indoor Weather Station The indoor weather station can be mounted in two ways: • with the table stand • on the wall with the use of a wall hanging screw (not included) 1. USING THE TABLE STAND The indoor weather station comes with the table stand already mounted. If you wish to use the table-stand all that is required is to place the indoor weather station in an appropriate location. 2. WALL MOUNTING a. b. c. d. Remove the table-stand.
TROUBLESHOOTING Problem: The LCD is faint. Solution: 1) Set the LCD contrast to a higher level. 2) Replace batteries. Problem: No outdoor temperature/humidity is displayed. Solution: 1) Remove all batteries, reinsert into the remote temperature sensor first, then into the indoor weather station. 2) Place remote temperature sensor closer to the indoor weather station. 3) Be sure all batteries are fresh.
