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.  
5
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.

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  
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  
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.

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.  
20  
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  
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.  
22  
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  
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  
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  
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.
