During the advance heating period and the premature deactivation of the heating system,
the icons or blink on the display. Outside the times-of-use, the controller monitors the
Night set point
(reduced room temperature). When the temperature falls below the night set
point, the controller heats with the max. flow temperature until the measured room tempera-
ture exceeds the adjusted value by 1 °C.
Note: Direct sunshine can cause the room temperature to increase and thus result in the pre-
mature deactivation of the heating system.
When the room temperature decreases while the heating system is temporarily outside its
times-of-use, this can prematurely cause the controller to heat up to the adjusted
Day set
point.

5.8 Flash adaptation
To ensure that the controller reacts immediately to room temperature deviations during rated
or reduced operation, the function block setting CO1, 2, 3 -> F09 - 1 needs to be made.
The heating is then always switched off as soon as the room temperature exceeds the
Day set
point
or
Night set point
by 2 °C.
Heating first starts again when the room has cooled off and the room temperature is 1 °C
above the
Set point
. The flow temperature set point is corrected if the
Cycle time
and
Gain K
P
are set to a value other than 0. The
Cycle time
determines the intervals at which the flow tem-
perature set point is corrected by 1 °C. A
Gain K
P
set to a value other than 0 causes a direct
increase/decrease in flow temperature set point when a sudden deviation in room tempera-
ture arises. A
Gain K
p
setting of 10.0 is recommended.
Note: Cooling loads, such as drafts or open windows, affect the control process!
Rooms may be temporarily overheated after the cooling load has been eliminated!
