Configuration
Location Identifier
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.
Operation Without Configuration
If the major and/or minor software version number in non-volatile memory does not
match the value stored in the program memory, the configuration data in the non-volatile
memory is set to default values. This causes the board to go into shutdown mode, since
the default configuration does not have a valid checksum.
The unit will not run without va
lid conf
iguration data. Table 46 shows invalid unit
configuration controller operation. Comm5 communications do not require valid
configuration data. All other functions require a complete set of valid configuration data.

This sequence can be overridden by and is ignored by the following sequences, listed
highest to lowest priority. For more information on control sequence descriptions, refer

configuration properties are public and may be changed at anytime by any
device. Changes to LonMark configuration properties are handled on the fly and do not
require the controller to be reset. The controller is responsible for range checking the
incoming values and taking the appropriate action if the valid ranges are violated. The
Rover service tool is required to setup Trane configuration properties.
