set-up of remote sensor units with the WS-7107U. These extra sensors can be purchased through the same dealer as this unit, or by contacting La Crosse Technology directly. A TX6 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 and the TX4U or TX7U will monitor temperature and humidity.
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 temp/humidity sensor units, and 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.
