Functions of the heating circuit
Note:
− Direct sunshine can cause the room temperature to increase and thus result in the
premature 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'.
Functions WE Conguration
Room sensor 0 CO1, 2 > F01 - 1
Outdoor sensor CO1 > F02 - 1
Optimization 0 CO1, 2 > F07 - 1
Parameters WE Switch position: value range
Day set point 20.0°C
: –5.0 to 150.0°C
Night set point 15.0°C
: –5.0 to 150.0°C
6.10 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 rst starts again when the room has cooled off and the room temperature is 1°C
above the set point. The ow temperature set point is corrected if the 'Cycle time' and 'KP
(gain)' are set to a value other than 0. The 'Cycle time' determines the intervals at which the
ow temperature set point is corrected by 1°C. A 'KP (gain)' set to a value other than 0
causes a direct increase/decrease in ow temperature set point when a sudden deviation in
room temperature arises. A 'KP (gain)' 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.
