Functions of the heating circuit
6 Functions of the heating circuit
Which controller functions are available depends on the selected system code number (Anl).
6.1 Outdoor-temperature-controlled control
When outdoor-temperature-compensated control is used, the flow temperature is controlled
based on the outdoor temperature. The heating characteristic in the controller defines the
flow temperature set point as a function of the outdoor temperature (see Fig. 3). The outdoor
temperature required for outdoor-temperature-compensated control can either be measured
at an outdoor sensor or received over the 0 to 10 V input.
