SET-UP of Multiple Units | La Crosse Technology WS-7138U instruction

IV. ADDING REMOTE TEMPERATURE/HUMIDITY SENSORS (OPTIONAL)

The WS-7138U is able to receive signals from 2 different remote temperature/humidity sensors. The remote temperature/humidity 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/humidity sensor units with the WS-7138U. 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 TX4U will monitor the temperature and humidity, a TX7U will monitor the temperature and humidity and display those values on a built in display, a TX3U will monitor temperature and display the temperature on its LCD, 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 temperature/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.

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 temperature/humidity sensor units.

3.Place all remote temperature/humidity 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 Set-Up Guide).
