Appendix C: Initial Settings
Your 651 controller is shipped with the initial configuration settings listed alphabetically in Table
20. Since the 651 unit stores most of the settings in non-volatile RAM, the values are not default
settings. Values stored in non-volatile RAM are saved when the power is turned off. When the
power is restored, the 651 unit “remembers” the latest configuration, not the initial configuration.
