This parameter triggers an automatic adaptation of the hea-
next parameter
ting curve slope to the characteristics of the building under per-
manent inclusion of outside, flow and room temperatures.
In order to determine the optimal heating curve longer
heating phases are required, so that a compensation between
input and output heat is assured. The adaptation triggers a
directed adjustment of the heating curve in dependence on the
control offset.
The value determined by adaptation is not saved. The number
of corrective steps rises as the deviation increases, with smaller
deviations the correction will also be minor. When changing
the heating curve slope at a later date it will be adapted
anew.
With active adaptation the heating curve slope flashes when
enquired by means of button

adaptation is completed and to adjust the slope value
determined by adaptation manually in Parameter 27
(Heating curve adjustment).
An adaptation is made under the following conditions:
– with active room sensor ( Par. 3 - room intrusion = 1)
– with heating curve adaptation switched on
– in all automatic programs during heating
– with permanent heating operation
– with averaged outside temperatures below 16 °C
– with room temperatures deviating more than 1 K from the set-
value
no adaptation takes place
– when the heating circuit is switched off
– with heating curve adaptation switched off
– during the optimization phases
– in all automatic programs during reduced operation
– during permanently reduced operation
– in case of defective or disconnected outdoor sensor
– with deactivated thermostat (room intrusion OFF)
– after the maximum temperature of the heat generator is
reached
Note:
GB
Heating curve adaptation is not in effect during pure
room control (i.e. parameter 4 - room factor = RC)
