Heat demand 0..10 V
The current heat demand can be transmitted to the heat source in the
form of a 0..10 V signal.
The temperature values corresponding to 0 V and 10 V and the
threshold value for a valid heat request can be set (refer to page 78).
State whether the 0..10 V heat demand output is used and how it is
controlled.
