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

6
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.

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
