4.207 Adaption of the heating curve
•
No heating curve adjustments required
•
Automatic adaption of the heating curve
The adaption facility learns from the different heating situations and matches the control
to the heating circuit at regular intervals. Also refer to section “Adaption sensitivities”
(operating lines 709
EXP
+ 710
EXP
).

In automatic mode (nominal room temperature set-
point
), the heating curve will automatically and continuously be adapted
Prerequisite is the presence of a room temperature detector.
The adaption facility automatically matches the heating curve to the type of building
construction and the heating requirements. Adaption gives consideration to room tem-
perature deviations, outside temperature characteristics and adaption sensitivity.
To achieve optimum adaption, the following situations should occur as rarely as possi-
ble - especially after commissioning - since this would reset certain calculations re-
quired for the adaption:
−
Manual correction of the heating curve (slope / parallel displacement)
−
Power failure
−
Changes to the room temperature setpoint
Every day at midnight, the room temperature control differential of the previous day is
evaluated. This evaluation leads to an automatic readjustment of the heating curve.
•
Simple
adaption
(range ):
At attenuated outside temperatures below 4 °C, it is only the slope of the heating
curve that is adapted
Within this temperature range, the readjustment is weighed with factor f2 and adap-
tion sensitivity 2 (operating line 710
EXP
).
•
Combined adaption (range ):
At attenuated outside temperatures of between 4 and 12 °C, it is partly the slope
and partly the parallel displacement of the heating curve that are adapted (heat
gains, operating line 708
EXP
).
Within this temperature range, the readjustment of the parallel displacement is
weighed with factor f1 and adaption sensitivity 1 (operating line 709
EXP
).
Within this temperature range, the readjustment of the slope is weighed with factor
f2 and adaption sensitivity 2 (operating line 710
EXP
).
•
No adaption (range ):
At attenuated outside temperatures above 12 °C, the heating curve will not be
adapted.
