ADDITIONAL EQUIPMENT
(not included)
1. 1 Philips screwdriver.
2. 2 Fresh AAA 1.5V batteries.
(for the indoor temperature station)
3. 2 Fresh AA 1.5V batteries.
(for the temperature sensor)

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 all 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 weather
stations)
4. DO NOT PRESS ANY BUTTONS
FOR 15 MINUTES.

6
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 the indoor
temperature and the outdoor temperature
after the 15 minutes please retry the set up as
shown on page five.
After both the indoor temperature and
outdoor temperature are displayed for 15
minutes you can place your remote
temperature sensor outdoors and set your
time.

7
Notes on Outdoor Sensor Placement
The remote temperature sensor should be
placed in a dry, shaded area. Fog and mist
will not harm your remote temp/humidity
sensor but direct rain must be avoided.
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.

TEMPERATURES
1. Press and release
the “MIN/MAX”
button, “MIN”
appears above and
to the right of each
temperature and the
recorded minimum
temperatures are
displayed along
with the time of the recorded minimum
outdoor temperature.

maximum temperatures—press and hold
the “MIN/MAX” button for 5 seconds.
C. ADDING ADDITIONAL
REMOTE TEMPERATURE
SENSORS (OPTIONAL)
The WS-7136U is able to receive signals
from 3 different remote temperature
sensors. Following are some brief
instructions for the basic set-up of

18
additional remote sensor units with the
WS-7136U. 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, 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.

19
1. It is necessary to remove the batteries
from all units currently in operation.
2. Remove the battery covers to all
remote sensor units.
3. Place all remote sensor units in a
numeric sequential order.
4. In sequential order, install batteries
(follow the same battery installation
procedures seen in section “I” of the
Detailed Set-Up Guide) into the
remote sensors.
5. Install batteries into the indoor
temperature station.
6. Follow the Detailed Set-Up Guide for
programming and operating
instructions.
