The receiver will beep 3 times to
indicate a successful assignment.
The setup tool provides additional
capabilities as well. The sensor can be
added as an averaging sensor or as a
backup to another Wireless sensor. A
maximum of four (4) averaging sensors
and one (1) backup may be assigned to

assigned to a particular UCM. These
options are selected by pressing the
" ADD/DELETE/PURGE" button. The
send button executes the command.
The receiver will beep 3 times to
