The controller includes a configured name/location ID location identifier. The maximum
length of the location identifier is 30 characters. You can use the Rover service tool to
download this identifier and easily identify the unit based on its physical location.

If the major and/or minor software version number in non-volatile memory does not

the default configuration does not have a valid checksum.
The unit will not run without valid configuration data.
