The following example illustrates applications avail-
able using the settings "Used as" (operating line 40)
together with "Heating circuit assignment" (operat-
ing lines 42 to 48).
Existing heating circuits 1 and 2 are controlled
centrally from room unit 1 for logistical reasons. The
room temperature sensor in room unit 1 is relevant
to only heating circuit 1 since climatic conditions for
heating circuit 2 may diff er from heating circuit 1.
Room unit 2 allows for separate temperature meas-
urements and individually setting of heating circuit
2. However, operating the occupancy button of unit
1 will activate all heat circuits. Example settings:-
