FB_BA_BuildingEnergyLevel

Selection of the building energy level based on a schedule (Sched) and a manual mode (EnergLvlMan).

The manual mode (EnergLvlMan) has the following values:

Value	Meaning
1	Automatic mode
2	manual selection Protection
3	manual selection Economy
4	manual selection Precomfort
5	manual selection Comfort

If Automatic mode is selected, the function block DeMuxEnergLvl sets the output bQ01. Since this output is not connected to the PrioSwi , the manual mode on the PrioSwi is disabled and the schedule Sched is active. This can assume the following values:

Value	Meaning
1	Protection
2	Economy
3	Precomfort
4	Comfort

The currently selected energy level is then displayed via the function block EnergLvlPr and made available via Publisher.

	The initialization of the template takes place within the method FB_Init.
