6 Functions of the heating circuit
Which controller functions are available depends on the selected system number (Anl).
6.1 Weather-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). The outdoor temperature required
for weather-compensated control can either be measured at an outdoor sensor or received us-
ing 0 to 10 V at UI1 input.
