Heating curve slope
As the heating curve slope is raised,
the flow temperature increases quicker
at lower outside temperature. In other
words, if the room temperature is not
correct at low outside temperatures but
correct at higher outside temperatures,
the heating curve slope requires read-
justment.
Increase adjustment:
Raises the flow temperature, especially
when outside temperatures are low.
Decrease adjustment:
Lowers the flow temperature, especially
when outside temperatures are low.
Heating curve displacement
Parallel displacement of the heating
curve is used to change the flow tem-
perature evenly across the entire outsi-
de temperature range. In other words, if
the room temperature is always too
high or too low, a readjustment must be
made with the help of the parallel dis-
placement.
Heating curve adaption
Adaption of the heating curve is used
by the controller to automatically adapt
the heating curve to the prevailing con-
ditions. In that case, a readjustment of
heating curve slope and parallel displa-
cement is not required. It can only be
switched on or off.
To assure this function, following must
be observed:
• A room sensor must be connected
• The Room influence setting must be
selected between 1 and 99
• There should be no thermostatic ra-
diator valves in the reference room
(mounting location of room sensor) (if
such valves are present, they must be
set to their fully open position).
