12.2.2 Saving the diagnostics values
The diagnostic values are written into a non-volatile memory every 15 minutes so that, in the
event of a power failure, only the diagnostic values of the previous 15 minutes are lost. The
values in the resettable parameters can be set to zero.
To do this, press the button for at least 5 seconds.
The diagnostic values which can be reset can be found in the table in section Overview of
diagnostics values (Page 257).
