5 Functions of the heating circuit
5.1 Weather-compensated control
When weather-compensated control is used, the flow temperature is controlled
accord- ing to the outdoor temperature. The heating characteristic in the
controller defines the flow temperature set point as a function of the outdoor
temperature (–> Fig. 3). The outdoor temperature required for weather-
compensated control is measured by an out- door sensor.
