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
readjustment.
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
temperature evenly across the entire
outside 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 displacement.
Heating curve adaption
Adaption of the heating curve is used
by the controller to automatically adapt
the heating curve to the prevailing
conditions. In that case, a readjustment
of heating curve slope and parallel
displacement 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
(QAA75)
 The Room influence setting must be
selected between 1 and 99
 There should be no thermostatic
radiator valves in the reference room
(mounting location of room sensor) (if
such valves are present, they must
be set to their fully open position).
