Detailed functional description
6.4.3 Comparison of rooms with different heat energy demands
classic / adaptive heating curve
A classic heating curve must be set to the room with the highest heat
energy demand. This means that the room that requires the highest flow
temperature is decisive for the setting of the heating curve.
Example with 3 rooms ( Fig. 21): at –15 °C outside temperature, the
following required flow temperatures result from the heating load
calculation:
• Bedroom: 36 °C
• Bathroom from 45 °C
• Children's bedroom 38 °C.

The set value for the heating curve at -15 °C outside temperature would
therefore be 45 °C in this example, regardless of whether the bathroom
currently requires heat.
The adaptive heating curve recognises whether a room currently
requires heat or not. To determine the flow temperature, only the rooms
with an active heat energy demand are considered. In the example
(bathroom: "measured room temperature" is greater than the "set room
temperature"), the bathroom would not be considered until a heat
energy demand is registered.
Compared to the classic heating curve, the adaptive heating curve in this
example would work for a few hours with a flow temperature that is 7 K
lower because, in contrast to the classic heating curve, the children's
room would be decisive at 38 °C and not the bathroom.
