set-up of remote temperature sensor units with the
WS-7215U. These extra 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
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 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.

A. SET-UP OF MULTIPLE UNITS
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 (follow the

same battery installation procedures seen in
section I. A) of the Detailed Set-Up Guide).

5. Install batteries into the indoor temperature

station.

6. Fo l l o w t h e D e t a i l e d S e t - U p G u i d e fo r

programming and operating instructions.

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

2. To view the Minimum/Maximum temperature: first

select which remote temperature sensor to read
data from (indicated by the “boxed” number), then
press the OUT button. Pressing this button once
will display the minimum temperature, and the
date and time the data was recorded. Pressing
this button a second time (while “MIN” is still
displayed, otherwise press the button twice) will
display the same data for the maximum
recordings.

3. To reset the Minimum/Maximum readings, it is

necessary to select which remote temperature
sensor you wish to reset. Press and hold the
OUT button for 5 seconds, the records for the
selected remote temperature sensor unit will be
reset.

MOUNTING

Note:

Before permanently mounting ensure that

the indoor temperature 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 temperature
station. To achieve a true temperature reading, avoid
mounting where direct sunlight can reach the remote
temperature sensor or indoor temperature station.
While the remote temperature sensor is weather
proof, avoid submersion in water or snow. We
recommend that you mount the remote temperature
sensor on an outside North-facing wall. The sending
range 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 15 minutes before permanently
mounting to ensure that there is proper reception.

The indoor temperature station should display a
temperature in the OUTDOOR LCD within 4 minutes
of setting up.

I. THE REMOTE TEMPERATURE SENSOR
The remote temperature sensor can be mounted in
two ways:
•

with the use of screws, or

•

using the adhesive tape.

A. MOUNTING WITH SCREWS
1) Remove the mounting bracket from the remote

temperature sensor.

2) Place the mounting bracket over the desired

location.

3) Through the three screw holes of the bracket,

mark the mounting surface with a pencil.

4) Screw mounting bracket onto the mounting

surface. Ensure that the screws are flush with
the bracket.

5) Insert the remote temperature sensor into the

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.

3) Adhere the tape to the designated area on the

back of the mounting bracket.

4) Remove the protective strip from the other side

of the tape.

5) Position the remote temperature sensor in the

desired location, ensuring that the indoor
temperature station can receive the signal.

II. THE INDOOR TEMPERATURE STATION
The indoor temperature 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).

A. USING THE TABLE STAND
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.

B. WALL MOUNTING
1) Remove the table-stand. To do this, pull down

on the stand from the rear and rotate forward.

2) Fix a screw (not included) into the desired wall,

leaving approximately 3/16 of an inch (5mm)
extended from the wall.

3) Place the indoor temperature station onto the

screw using the hanging hole on the backside.

4) Gently pull the indoor temperature station down

to lock the screw into place.
