11.4.3 Setpoint of room temperature-compensated control

The setpoint is generated based on the deviation of the actual room temperature from
the setpoint. In addition, the heating curve with a fixed outside temperature of 0 °C is
taken into consideration.

11.4.4 Setpoint of weather-compensated control with room
temperature influence
Here, in addition to the outside temperature and the room temperature setpoint, the
heating curve and the room temperature influence act on the flow temperature setpoint.
