QUICK SETUP

 

Hint: Use good quality Alkaline
Batteries and avoid rechargeable
batteries.

1. Have the indoor temperature station
and remote temperature sensor 3 to
5 feet 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 temperature station.

(All remote temperature sensors must be
started before the indoor temperature
station)

4. DO NOT PRESS ANY BUTTONS
FOR 15 MINUTES.

 

 

 

In this time the indoor temperature
station and remote temperature sensor
will start to talk to each other and the
display will show both the indoor
temperature and an outdoor temperature.
If the indoor temperature station does
not display both temperatures after the
15 minutes please retry the set up as
stated above. After both indoor and
outdoor temperatures are displayed for
15 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
can have up to 30 feet of resistance and
an interior wall can have up 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
temperature station after the 15 minutes
have passed please follow the steps in
the detailed set up guide on page 8.

FEATURES

 

Minimum and Maximum Temperatures

 

1. Press and release the “MIN/MAX”
button, “MAX” appears between the
indoor and remote temperatures.
2. The recorded maximum indoor and
remote temperature is displayed.
3. Press and release the “MIN/MAX”
button.
4. “MIN” appears between the indoor and
remote temperatures.
5. The recorded minimum temperature is
displayed.
6. Press and release the “MIN/MAX”
button to exit min/max mode.
7. To view optional additional sensors,
press and release the “CH” button
while viewing the minimum or
maximum temperatures.

 

 

 

Resetting Min and Max Temperatures

 

To reset both the minimum and maximum
temperatures—press and hold the
“MIN/MAX” button for 5 seconds.

 

Adding Additional Remote
Temperature Sensors (optional)

 

The WS-9055U is able to receive signals
from 3 different remote temperature
sensors. Following are some brief
instructions for the basic set-up of
remote temperature sensor units with the
WS-9055U. 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 of water or soil via a
probe.

When setting up multiple remote
temperature sensors, it is important to
remove the batteries from all existing
units in operation, then to insert batteries
first into all the remote temperature
sensors. Second install batteries into the
indoor weather station and do not press
any buttons for ten minutes.
Transmission problems will arise if this
is not done correctly.

To view the temperature of a different
remote temperature sensor unit, press
and release the “CH” button. A shift
from one number to the next should be
observed in the OUTDOOR LCD.

 

 

 

 

 

 

 

 

 

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-9055U 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.

 

 

 

 

 

 

 

 

 

 

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.

 

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.

 

MOUNTING

Note: To achieve a true temperature
reading, avoid mounting in direct sunlight.
We recommend that you mount the remote
temperature sensor on a North-facing wall.
The sending range is 80ft; obstacles such as
walls, concrete, and large metal objects will
reduce the range. Place both units in their
desired location before permanently
mounting.

 

Remote Temperature Sensor

 
Remove the mounting bracket from the
remote temperature sensor. Mount the
bracket in the desired location with either
screws or adhesive tape. Insert remote
temperature sensor into mounting bracket.

 

 

Indoor Weather Station

 

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.

 

To wall mount the indoor weather station
first remove the table stand. Next insert an
appropriate screw in your desired location.
Using the integrated hanging hole on the
back of the unit, slip indoor weather station
over the screw and pull down to secure.

 

TROUBLESHOOTING

NOTE: For problems not solved, please
contact La Crosse Technology via e-mail or
phone, or visit our website,
www.lacrossetechnology.com

 

Problem: The LCD is faint

Solution: Replace batteries

 

Problem: No outdoor temperature is
displayed.

Solution:

1. Remove all batteries, reinsert into
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.
4. Place remote temperature sensor and
indoor weather station in position so the
straight-line signal is not passing
through more than two or three walls.

Problem: Temperatures do not match if
units are placed next to each other.

Solution:

Each temperature sensor is manufactured to
be accurate to within 1 degree plus or minus
and under normal conditions, so two sensors
could be as much as 2 degrees different.
However, the difference can be exaggerated
further because the sensors are designed for
different working environments. The indoor
sensor is less responsive to ambient air
currents because of the shielding effect of
the display's case. In addition, the case can
act as a heat sink to absorb and store heat
from external sources (i.e. handling of the

case or radiant heat). Also, the much greater
range of the outdoor temperature sensor
requires a different calibration curve than the
indoor range. Error is usually greater at the
extreme ends of a range, making it harder to
compare different ranges with different
curves. Under non-laboratory conditions, it
is difficult to compensate for the above
factors and obtain an accurate comparison.

 

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.
• Do not subject the units to unnecessary
heat or cold by placing them in the
oven or freezer.

• Opening the casings invalidates the
warranty. Do not try to repair the unit.
Contact La Crosse Technology repairs.
