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.

4

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
will have up to 20 feet of resistance and
an interior wall will have up to 10 feet

5

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.

DETAILED SETUP GUIDE

I.

BATTERY INSTALLATION

A.

REMOTE TEMPERATURE

SENSOR

1.

Remove the mounting bracket.

2.

Remove battery cover

3.

Observing the correct polarity, install
2 AA batteries—make sure they do not
spring free, or start-up problems may
occur. Replace cover.

7

B.

INDOOR TEMPERATURE

STATION

Note:

After the batteries are installed, DO

NOT press any buttons. This may interfere

with the signals, causing temperatures to
register incorrectly.

1.

Remove the battery cover on the
backside.

2.

Observing the correct polarity, install
2 AAA batteries.

3.

Replace battery cover.

4.

Wait 15
minutes before
pressing any
buttons.

FEATURES

A.

MINIMUM AND MAXIMUM

TEMPERATURES

1.

Press and release the “MIN/MAX”
button, “MIN” appears in the
temperature LCD’s and the recorded
minimum temperatures are displayed.

2.

Press and release the “MIN/MAX”
button to toggle to the maximum
temperatures.

B.

RESETTING THE MINIMUM AND

MAXIMUM TEMPERATURES

1.

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

C. ADDING ADDITIONAL

REMOTE TEMPERATURE
SENSORS (OPTIONAL)

1.

The WS-9002U 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-9002U. These extra
sensors can be purchased through the
same dealer as this unit, or by
contacting La Crosse Technology
directly. A TX6 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 use in pools, spas, etc.

Note: When setting up multiple units it
is important to remove the batteries
from all existing units in operation,
then to insert batteries first into all the
remote temperature sensor units, and in
numeric sequence. Second, install

10

batteries into the indoor temperature
station. Transmission problems will
arise if this is not done correctly and if
the total time for set-up exceeds 6
minutes.

2.

It is necessary to remove the batteries
from all units currently in operation.

3.

Remove the battery covers to all
remote temperature sensor units.

4.

Place all remote temperature sensor
units in a numeric sequential order.

5.

In sequential order, install batteries
(follow the same battery installation
procedures seen in section “I” of the
Detailed Set-Up Guide).

6.

Install batteries into the indoor
temperature station.

D.

VIEWING AND OPERATING
WITH MULTIPLE REMOTE
TEMPERATURE SENSOR UNITS

1.

To view the temperature of a different
remote temperature sensor unit, press
and release the “CH” button. A shift

11

from one “boxed” number to the next
should be observed in the OUTDOOR
LCD.

2.

To view the Minimum/Maximum
temperature: first select from which
remote temperature sensor to read data
(indicated by the “boxed” number).
Pressing and releasing the
“MIN/MAX” button will toggle
through the minimum and maximum
indoor temperature, and the minimum
and maximum outdoor temperature.

3.

To reset the Minimum/Maximum
readings, press and hold the
“MIN/MAX” button for five seconds.

III.

MOUNTING

Note: To achieve a true temperature

reading, avoid mounting in direct sunlight.
We recommend that you mount the remote
temperature sensor on an outside North­facing wall. The sending range is 80ft;
obstacles such as walls, concrete, and large
metal objects will reduce the range. Place

12

both units in their desired location before
permanently mounting.

A.

REMOTE TEMPERATURE

SENSOR

1.

Remove the mounting bracket from
the remote temperature sensor

2.

Mount using either screws or
adhesive tape.

3.

Reattach the remote temperature
sensor to the mounting bracket.

B.

THE TEMPERATURE STATION

1.

The indoor temperature 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
temperature station in an appropriate
location.

2.

To wall mount, remove the table
stand. To do this, pull down on the
stand from the rear and rotate forward.

a)

Fix a screw (not included) into the

desired wall, and place the indoor

13

temperature station onto the screw
using the hanging hole on the
backside. Gently pull the indoor
temperature station down to lock the
screw into place.

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, and then into the
indoor temperature station.

2) Place remote temperature sensor closer to
the indoor temperature station.

3) Be sure all batteries are fresh.

14

4) Place remote temperature sensor and
indoor temperature 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 temperature sensors could
be as much as 2 degrees different. However,
the difference can be exaggerated further
because the temperature 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). In
addition, 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

15

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 for
repairs.
