QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the indoor weather station and remote temperature sensor 3 to 5
apart.
2. Batteries should be out of both units for 10 minutes.
3. 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)
4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.
In this time the indoor weather station and remote temperature sensor will start to
talk to each other and the indoor weather station will show both the indoor
temperature and an outdoor temperature. If the indoor weather station does not
display both temperatures after the 10 minutes please retry the set up as stated above.
After both indoor and outdoor temperatures are displayed for 10 minutes you can
place your remote temperature sensor outdoors and set your time.
The remote temperature sensor should be placed in a dry, shaded area. The remote
temperature 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 temperature 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 on pages 8 and 9.
Note: The remote temperature 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.

Within a few seconds the indoor temperature, indoor relative
humidity and the weather icons (sun and clouds) will be displayed.
If not, then remove batteries for 10 seconds and reinstall. If the
outdoor temperature is not displayed within four minutes, remove
batteries from both units, wait 10 seconds, and reinstall. The time
will show -:-- and start searching for the signal. If it successfully
receives the time signal (usually at night), it will display the
correct time (default is Eastern).

Forecast icon
The weather forecasting feature is estimated to be 75% accurate for the next
12 to 24 hours. The weather forecast is based solely upon the change of air
pressure over time. The WS-7049U 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 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
1. Other possible displays in the FORECAST LCD are 2
weather tendency arrows one that points up (above the
forecast icon) and one that points down (below the
forecast icon).
2. These arrows reflect current changes in the air pressure.
3. An arrow pointing up indicates that the air pressure is
increasing and the weather is expected to improve or
remain good.
4. An arrow pointing down indicates that the air pressure is
decreasing and the weather is expected to become worse
or remain poor.
5. No arrow means the pressure is stable.

II. Indoor Temperature and Humidity
The current indoor relative humidity (viewed below the time) and
temperature (viewed below the relative humidity) are displayed in the
INDOOR LCD.
III. Outdoor Temperature
The outdoor temperature is viewed in the OUTDOOR LCD. When there is
more than one remote temperature sensor unit in operation, a arrow will
appear above the CH 1 2 3 area at the bottom of the LCD. This indicates
which remote temperature sensor unit (1, 2 or 3) is currently displaying its
data in the OUTDOOR LCD. (This feature is explained in further detail in
section V—Adding Remote Temperature Sensors).
IV. Minimum and Maximum Temperature Records
The WS-7049U keeps a record of the MINIMUM and MAXIMUM
temperature for both the indoor and outdoor modes.
A. Viewing Minimum and Maximum Temperature Records
1. Press and release the “MIN/MAX/RESET” button.
2. MAX will appear below the indoor temperature.
3. The maximum recorded indoor and outdoor temperatures
will be displayed in their respective areas.
4. Press and release the “MIN/MAX/RESET” button.
5. MIN will appear below the indoor temperature.
6. The maximum recorded indoor and outdoor temperatures
will be displayed in their respective areas.
7. Press and release the “MIN/MAX/RESET” button.
8. The current indoor and outdoor temperatures will be
displayed in their respective areas.
B. Resetting the Minimum and Maximum Temperature
Records

Press and hold the “MIN/MAX/RESET” button for 5 seconds
to reset the minimum and maximum recorded temperatures.
V. Adding Remote Sensors (optional)
The WS-7049U is able to receive signals from 3 different remote
temperature sensors. The remote temperature 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 temperature sensor units with the
WS-7049U. These extra remote temperature sensors can be purchased
through the same dealer as this unit, or by contacting La Crosse Technology
directly. A TX6U will monitor temperature only, 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 remove the batteries
from all existing units in operation. Then insert batteries into all the
remote temperature sensor units in numeric sequence. 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.
A. Set Up of Multiple Remote Sensors
1. It is necessary to remove the batteries from all units currently
in operation.
2. Remove the battery covers to all remote temperature sensor
units.
3. Place all remote temperature sensor units in a numeric
sequential order.
4. In sequential order, install batteries into the remote sensors.
5. Install batteries into the indoor weather station.
6. Follow the Detailed Set-Up Guide for programming and
operating instructions.
