ABOUT WWVB (Radio Controlled Time)  
The NIST (National Institute of Standards and Technology—Time and Frequency  
Division) WWVB radio station 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 signal every  
night when reception is best. The WWVB radio station derives its signal from the  
NIST Atomic clock in Boulder, Colorado. A team of atomic physicists is  
continually measuring every second, of every day, to an accuracy of ten billionths of  
a second per day. These physicists have created an international standard,  
measuring a second as 9,192,631,770 vibrations of a Cesium-133 atom in a vacuum.  
For more information about WWVB please see the NIST website at

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 indoor weather station and remote thermo/hygro sensor will start to  
talk to each other and the indoor weather station will show both the indoor  
temperature and humidity and the outdoor temperature and humidity. If the indoor  
weather station does not display all values after the 10 minutes please retry the set up  
as stated above. After all values are displayed for 10 minutes you can place your  
remote thermo/hygro sensor outdoors and set your time.  
The remote thermo/hygro sensor should be placed in a dry, shaded area. The remote  
thermo/hygro sensor has a range of 80 feet. Any walls that the signal will have to  
pass through will reduce distance. An outdoor wall or window will have 20 to 30  
feet of resistance and an interior wall will have 10 to 20 feet of resistance. Your  
distance plus resistance should not exceed 80 ft. in a straight line.  
NOTE: Fog and mist will not harm your remote thermo/hygro sensor but direct rain  
must be avoided.  
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 Thermo Hygro Sensor transmits a signal every 3 minutes; after  
the batteries have been installed, the 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.

D. Time  
There are two methods by which the time can be set:  
1. Automatically via WWVB reception, or  
2. Manually.  
1. WWVB (Remote Control Time)  
This method requires you to do nothing, except wait for the signal  
to be received and to select a time zone. Reception usually takes  
approximately 6-10 minutes during optimal conditions. The best  
conditions for reception is at night, between midnight and 6:00  
am—when there is less atmospheric interference. To keep your  
time as accurate as possible, the indoor weather station conducts a  
WWVB search every night between these hours and overrides any  
manually set time. The WWVB tower icon (appearing in the TIME  
LCD) will flash when a signal-search is in progress, will remain  
steady when the signal has been received, and nothing will be  
displayed in all other situations. If the WWVB time has not been  
received 10 minutes after battery installation you may manually set  
the time or wait for WWVB reception. Once the WWVB time  
signal is received it will override the manually set time.

FEATURES OF THE WS-7078U  
12  
Download from Www.Somanuals.com. All Manuals Search And Download.  
WWVB Tower Icon (indicates time  
reception)  
Alarm icon  
Weather Tendency Arrow  
Forecast icon  
Comfort Level Indicator  
Satellite icon (indicates  
outdoor transmission)  
I. Weather Forecast  
The weather forecasting feature is estimated to be 75% accurate. The  
weather forecast is based solely upon the change of air pressure over time.  
The WS-7078UF 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  
13  
Download from Www.Somanuals.com. All Manuals Search And Download.  
There are 3 possible weather icons that will be displayed in the  
FORECAST LCD:  
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 “partly  
sunny” to “cloudy” or the reverse. It will not change from “sunny”  
directly to “rainy”, although it is possible for the change to occur  
quickly. If the symbols do not change then the weather has not  
changed, or the change has been slow and gradual.  
B. Weather Tendency Arrows  
Other possible displays in the FORECAST LCD are 2 weather  
tendency arrows, 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. An 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.  
II. Indoor Temperature, Humidity, and Comfort Level Indicator  
14  
Download from Www.Somanuals.com. All Manuals Search And Download.  
The current indoor temperature (viewed on the left) and relative humidity  
(viewed on the right) are displayed in the INDOOR LCD. The comfort  
level indicator is located at the center of the INDOOR LCD. The comfort  
level indicator will display a happy face icon 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 icon will be displayed when the temperature and  
humidity are outside the mentioned ranges.  
III. Outdoor Temperature and Humidity  
The outdoor temperature and humidity is viewed in the OUTDOOR LCD.  
When there is more than one remote thermo/hygro sensor unit in operation  
a “boxed” number will appear to the right of the temperature. This  
indicates which remote thermo/hygro sensor unit (1, 2, or 3) is currently  
displaying its data in the OUTDOOR LCD. (This feature is explained in  
further detail in section VIAdding Remote Thermo/hygro Sensors).  
IV. Minimum and Maximum Temperature Records  
The WS-7078UF keeps a record of the MINIMUM and MAXIMUM  
temperature and the time and date of their occurrence, for both the indoor  
and outdoor modes.

VI. Adding Remote Thermo/hygro Sensors (OPTIONAL)  
The WS-7078UF is able to receive signals from as many as 3 different  
remote thermo/hygro sensors. The remote sensor model(s) that you choose  
will come with their own set of instructions, follow these instructions for a  
complete guide to setting up. Following are some brief instructions for the  
basic set-up of remote sensor units with the WS-7078U. These extra remote  
sensors can be purchased through the same dealer as this indoor weather  
station or by contacting La Crosse Technology directly. A TX4U will  
monitor temperature and humidity, a TX3U will monitor temperature only,  
and the TX3UP will monitor water or soil temperature via a probe.  
Note: When setting up multiple remote sensors it is important to remove  
the batteries from all existing units in operation, then to insert batteries  
first into all the remote sensors. Second install batteries into the indoor  
weather station. Transmission problems will arise if this is not done  
correctly and if the total time for set-up exceeds 6 minutes.

MOUNTING  
19  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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 where direct sunlight can reach the  
remote thermo/hygro sensor. We recommend that you mount the remote  
thermo/hygro sensor on a North-facing wall. The transmitting range of the  
remote thermo/hygro sensor is 80ft. Obstacles such as walls, concrete, and  
large metal objects can reduce the range. Place both units in their desired  
location and wait approximately 10 minutes before permanently mounting  
to ensure that there is proper reception. The indoor weather station should  
display a temperature in the OUTDOOR LCD within 4 minutes of setting  
up.  
I. Remote Thermo/hygro Sensor  
A. Mounting With Screws  
1. Remove the mounting bracket/receptor from the packaging.  
2. Place the mounting bracket over the desired mounting surface.  
3. Through the 2 screw holes of the bracket mark the mounting surface  
with a pencil.  
4. Where marked, start the screw holes using the provided screws.  
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. 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.  
II. The Indoor Weather Station  
A. The indoor weather station can be mounted in two ways:  
with the table stand or,  
on the wall with the use of a wall hanging screw (not included).  
1. Using the Table Stand  
a. 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. Remove the table-stand. To do this, pull down on the stand  
from the rear and rotate forward.  
b. Fix a screw (not included) into the desired wall, leaving  
approximately 3/16 of an inch (5mm) extended from the wall.
