Functions of the heating circuit

5 Functions of the heating circuit

Which controller functions are available depends on the selected system code number (Anl).

5.1Functioning principle

The heating circuit with the highest flow set point has priority. This principle applies to all heat- ing circuits with mixing valves. In systems Anl 3, 5 and 8, the pump circuit has priority. The flow set point of the heating circuit with priority is controlled by the valve in the pre-control circuit. If several heating circuits have the same flow set point, the heating circuit with lowest number al- ways has priority and is controlled by the primary valve.

5.2Weather-compensated control

When weather-compensated control is used, the flow temperature is controlled according to the outdoor temperature. The heating characteristic in the controller defines the flow temperature set point as a function of the outdoor temperature (–> Fig. 2).
