5.1

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. 4). The outdoor temperature
required for weather-compensated control is either measured at the outdoor sensor or re-
ceived as an 0 to 10 V signal.
