4.5 Activating emergency operation
It is possible to activate the emergency operation for certain
types of heat source by selecting the heat source menu item
from the main menu. In emergency operation the heat source
enters the heating mode until the burner has reached the set
flow temperature. A heat supply for heating and DHW is thus
guaranteed in the event of a fault until a contractor has repaired
the heating system.
