Weather-compensated control

When weather-compensated control is used, the flow temperature is adjusted depending on
the outdoor temperature. The heating characteristic in the controller defines the flow temper-
ature set point as a function of the outdoor temperature (–> Fig. 5). The outdoor temperature
required for weather-compensated control can either be measured at an outdoor sensor or
transmitted from a connected device bus.
