Curvature factor of the heating characteristic for heating circuit 1
The curvature factor takes account of the heat-dissipating properties of the heating system. Particularly
for higher outdoor temperatures (typically 10...20 ° C), the secondary flow temperature can be modified
efficiently with this parameter if required.

Influence of extraneous heat on heating characteristic 1 (heating circuit 1)
A continuous supply of extraneous heat (e.g. presence of people, heat dissipation of machines) can be
compensated for by shifting the base point of the heating characteristic towards lower outdoor
temperatures.

Room-temperature link-up for heating circuit 1, room temperature > room-temperature setpoint
If a room-temperature signal is available for heating circuit 1, and if the room temperature is higher than
the corresponding setpoint, these deviations (per K) are compensated for automatically by reducing the
flow-temperature setpoint (according to heating characteristic 1).

Room-temperature link-up for heating circuit 1, room temperature < room-temperature setpoint
If a room-temperature signal is available for heating circuit 1, and if the room temperature is below the
corresponding setpoint, these deviations (per K) are compensated for automatically by increasing the
flow-temperature setpoint (according to heating characteristic 1).
