Nominal temperature setting of the required comfort temperature of hot water.
The adjusted heating curve uses the required temperature in the space from 20 °C. If the required/space
temperature changes, the heating curve is also changed. The heating curve displays the required temperature into
the heating circuit in dependence on the corrected outdoor temperature.
At using the space devices QAA74, QAA75 etc. the heating curve is extra corrected by the parameters Adjusted
space temperature and Influence of space.
