VI. Set-up of Multiple Units

V. Adding Additional Remote Sensors (Optional)

The WS-7391U is able to receive signals from 3 different remote sensors. These extra remote sensors can be purchased through the same dealer as this unit. A TX4U will monitor the temperature and humidity, 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 insert batteries first into all the remote sensors, 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.

1.It is necessary to remove the batteries from all units currently in operation.

2.Remove the battery covers to all remote sensors.

3.Place all remote sensors in a numeric sequential order.

4.In sequential order, install batteries following the same battery installation procedures seen in Detailed Set-Up Guide section of this manual.

5.Install batteries into the indoor weather station.

6.Follow the Detailed Set-Up Guide for programming and operating instructions.
