Outside the times-of-use, reduced set points are used for control:
The reduced flow set point is calculated as the difference between the adjusted
values for
Day set point
(rated room temperature) and
Night set point
(reduced
room tempera- ture).
The
Max. flow temperature
and
Min. flow temperature
parameters mark the
upper and lower limits of the flow temperature. A separate gradient characteristic
can be selected for the limitation of the return flow temperature.
Examples for adjusting the characteristic:
Old building, radiator design 90/70:
Gradient approx. 1.8
New building, radiator design 70/55:
Gradient approx. 1.4
New building, radiator design 55/45:
Gradient approx. 1.0
Underfloor heating depending on arrangement: Gradient smaller than
0.5
Note:
Particularly for control operation without room sensor, the room
temperatures set for day (Day set point) and night (Night set point) only become
effective satisfactorily when the heating characteristic has been adapted to the
building/heating surface layout.
