The controller generates the boiler temperature setpoint based on the boost set here
and the current flow temperature setpoint:
The greater the temperature differential between boiler flow and mixing heating circuit,
the quicker the required setpoint can be reached.

Defines the influence of room temperature setpoint deviations on the controlled system.
The room influence can be activated and deactivated (operating line 721).
