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.

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.

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.

B. RESETTING THE MINIMUM AND
MAXIMUM TEMPERATURES
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)
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
17
nload from Www.Somanuals.com. All Manuals Search And Downl
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.
18
nload from Www.Somanuals.com. All Manuals Search And Downl
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.

D. VIEWING AND OPERATING
WITH MULTIPLE REMOTE
SENSOR UNITS
1. To view the temperature of a different
remote 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 from which
remote temperature sensor to read data
from (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.

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 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
temporarily to test reception capability
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.
21
nload from Www.Somanuals.com. All Manuals Search And Downl
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
weather station in your desired
location.
2. To wall mount:
a) Remove the table stand by pulling
down on the stand from the rear and
rotating forward.
b) Fix a screw (not included) into the
desired wall.
c) Place the indoor weather station
onto the screw using the hanging
hole on the backside.
d) Gently pull the indoor weather
station down to lock the indoor
weather station into place.

TROUBLESHOOTING
NOTE: For problems not solved, please
contact La Crosse Technology via e-mail or
phone, or visit our website,
Problem: The LCD is faint
Solution: Replace batteries
Problem: No outdoor temperature is
displayed.
Solution:
1) First try to re-establish communication
between the remote sensor and indoor
temperature station by moving both units
to within three to five feet of each other.
Wait about ten minutes and then check
for a temperature.
2) If this does not work please remove the
batteries from both units and restart the
system (please see Detailed Set-up on
page nine through eleven).
Note: Please make sure when restarting the
system that all batteries are fresh.
23
nload from Www.Somanuals.com. All Manuals Search And Downl
3) Once the system has been reset and you
have a temperature reading from the
sensor, temporarily place the remote
temperature sensor in the previous
location.
Note: If there is an outdoor temperature
displayed when the two units are close
together there was either too much distance
between the two units previously or some
type of interference that was causing poor
reception.
4) If after 15 minutes the temperature is not
displayed you will need to choose
another location for placement of the
temperature sensor.
5) The best way of doing this is to move the
sensor 10 feet closer to the indoor
temperature station.
6) After moving the remote temperature
sensor please wait 15 minutes to give the
indoor temperature station time to re-
acquire the signal.
24
nload from Www.Somanuals.com. All Manuals Search And Downl
Problem: Temperatures do not match if
units are placed next to each other.
Solution: Each temperature sensor is
manufactured to be accurate to within 2
degree plus or minus and under normal
conditions. It is possible for two
temperature sensors to be as much as 4
degrees different. 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 indoor
temperature station’s case. In addition, the
casing 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
ends of a range, making it harder to compare
different ranges with different curves. Under
non-laboratory conditions, it is difficult to
25
nload from Www.Somanuals.com. All Manuals Search And Downl
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.
