disabled, until the error is removed or resolved.
• If changes are made to parameters and saved,
most settings take effect immediately. Any
change to fan speeds will take effect and cause
the configuration menu to exit immediately to
begin tracking speeds via the on-board

in effect, all unsaved values will be discarded
and the error codes will be displayed.
