Functions of the heating circuit
Depending on the room sensor, the controller switches off the heating system up to one hour
before the time-of-use ends. The controller chooses the deactivation time such that the room
temperature does not drop significantly below the desired value until the time-of-use ends.
During the advance heating period and the premature deactivation of the heating system, the
or
icon blink on the display.
Outside the times-of-use, the controller monitors the 'Night set point' (reduced room tempera-
ture). When the temperature falls below the night set point, the controller heats with the max.
flow temperature until the measured room temperature exceeds the adjusted value by 1 °C.
−
Direct sunshine can cause the room temperature to increase and thus result in the prema
-
ture deactivation of the heating system.
−
When the room temperature decreases while the heating system is shortly outside its times-
of-use, this can prematurely cause the controller to heat up to the 'Day set point'.

6.9 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' or 'Gain
KP' 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 KP' set to a value other than 0 causes a
direct increase/decrease in flow temperature set point when a sudden deviation in room tem-
perature arises. We recommend a 'Gain KP' setting of 10.0.
