20 Lifecycle function

If the startup counter exceeds a defined threshold, a display error code is set and
displayed. The error can be acknowledged.
The display code is always set in standby (when there is no heat request).
Hence, the moment the threshold is exceeded, the user is notified that the end of the
lifecycle of the LMV37.4 will soon be reached.
