contacting La Crosse Technology directly. A TX4U will monitor temperature and humidity, a TX3U will monitor temperature only 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 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
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 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. A) of the Detailed

B.VIEWING AND OPERATING WITH MULTIPLE THERMO HYGRO SENSOR UNITS
1.To view the temperature of a different Thermo Hygro Sensor unit, press 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 Thermo Hygro Sensor to read data from (indicated by the “boxed” number). Then press the OUT button. Pressing this button once will display the minimum temperature, 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 Thermo Hygro Sensor you wish to reset. Press
