4.46 Adaption of heating curve

No heating curve adjustments required.
Automatic adaption of heating curve.
The adaptation facility learns from the different heating situations and matches the
control to the heating circuit at regular. For details, refer to "adaptation sensitivities" in
Index.
Setting range
0 / 1
The setting will switch automatic adaption of the heating curve on or off.
Entry:
0 Automatic adaption inactive: The heating curve maintains the settings made
1 Automatic adaption active: In automatic mode (nominal room temperature
setpoint ), the heating curve will automatically and continuously be adapted
Prerequisite for this function is the use of a room temperature sensor.
4.46.1 Adaption
The adaption facility automatically matches the heating curve to the type of building
construction and the heating requirements. Adaption gives consideration to room
temperature deviations, outside temperature characteristics and adaption sensitivity.
To achieve optimum adaption, the following situations should occur as rarely as
possible - especially after commissioning - since this would reset certain calculations
required for the adaption:
−
Manual readjustment of heating curve (press plus / minus buttons)
−
Power failure
−
Heating curve set to -- –
−
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.
In this temperature range, the readjustment is weighted with factor f2 and adaption
sensitivity 2.
• Combined adaption (range
At attenuated outside temperatures of between 4 and 12 °C, it is partly the slope and
partly the parallel displacement which are adapted.
In this temperature range, the readjustment of the parallel displacement is weighed
with factor f1 and adaption sensitivity 1.
In this temperature range, the readjustment of the slope is weighted with factor f2
and adaption sensitivity 1.
