Priority levels 3, 4, 7, and 9-16 may be freely allocated with use cases. In this 
way, certain controls can be assigned other priorities as needed (vacation plan-
ning, night operation, etc.). 
Example: 
If employees switch the lights on in their offices, a service executes this 
switching process with priority 8. . For operation during vacations, it may be 
advisable to completely switch off certain technical devices and the lighting 
for the duration of the vacation. This action requires a higher priority. If a fire 
or another emergency occurs, the caretaker can control the lighting of the en-
tire office complex and other measures with a general switch. Such emergency 
controls have the highest priority.
