Heating curve
The set heating curve ensures that the flow tem -
perature setpoint changes depending on the out-
side temperature.
When setting the heating curve, consideration can
be given to the type of building structure (thermal
insulation) and the type of plant.
The slope of the heating curve and the absolute
temperature level of the flow temperature setpoints
(parallel displacement) can be set.
Heating curve slope - great differences in the
slope lead to great flow temperature changes at
low outside temperatures. lf the room tempera-
ture only deviates at low outside temperatures, the
slope must be readjusted.
Increasing the value raises the flow temperature,
especially at low outside temperatures.
Decreasing the value lowers the flow temperature,
especially at low outside temperatures.
The heating curve is correctly set when
the desired room temperature is main-
tained throughout the entire heating
season despite changes to outdoor
temperatures.
i
The adjusted heating curve is based
on a room temperature setpoint of 20
°C. lf the room temperature setpoint is
changed, the heating curve adjusts it-
self automatically.
i
Heating curve displacement - A parallel dis-
placement of the heating curve produces a general
change of the flow temperature, uniformly across
the whole outside temperature range.
lf the room temperature is always too high or too
low, it is recommended to make use of the parallel
displacement.
Heating curve adaptation - is used by the con-
troller to automatically adapt the heating curve to
the type of building structure.
To assure this function, following must be observed:
• A room sensor must be connected;
•
“Room influence” must be set to a value be -
tween 1 and 99;
• There should be no thermostatic radiator valves
in the reference room (location of room sensor);
if such valves are installed, they must be fully
opened;
