5.7 Flash adaptation
To ensure that the controller reacts immediately to room temperature deviations
during rated or reduced operation, the function block setting CO1, 2 -> 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 temperature 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 devia- tion in room temperature 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!

5.7.1 Flash adaptation without outdoor sensor
The flow temperature control starts with Day set point for flow in rated operation or
with Night set point for flow in reduced operation as no set points calculated using
character- istics exist without an outdoor sensor. The Cycle time determines the
intervals at which the flow temperature set point is corrected by 1 °C. 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
