10.4.6 Motor kick
A periodic motor kick can be activated to avoid soiling (dust) and seizing of HR
during extended off periods.
When motor kick is active, HR is switched on for 30 seconds once a week
regardless of any other functions and settings.
The motor kick is activated by setting "Motor kick" to "Yes". If the setting is "No",
there is no motor kick.
