V. Adding Additional Remote Sensors (Optional)
The WS-7390U 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.
VI. 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 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.
