Press and hold the 

“MIN/MAX/RESET”

 button for 5 seconds 

to reset the minimum and maximum recorded temperatures. 

V.  Adding Remote Sensors (optional) 
 

The WS-7042TWC is able to receive signals from 3 different remote 
temperature sensors.

   

The remote temperature sensor model(s) that you 

choose will come with their own set of instructions.  Follow these 
instructions for a complete guide to setting up. Following are some brief 
instructions for the basic set-up of remote temperature sensor units with the 
WS-7042TWC. These extra remote temperature 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 measuring soil or water 
temperatures.. 
 

Note:  When setting up multiple units it is important to remove the batteries 
from all existing units in operation.  Then insert batteries into all the 
remote temperature sensor units in numeric sequence.  Second, install 
batteries into the indoor weather 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 Remote Sensors 

 

 

 

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 into the remote sensors. 
5.  Install batteries into the indoor weather station. 
6.  Follow the Detailed Set-Up Guide for programming and 

operating instructions.
