Making use of the building's thermal storage capacity.
Quick setback is dependent on whether or not a room sensor is used. Therefore, we
speak of quick setback with or without room influence.
This setting is active only if no room sensor is used.
Setting range
0...20
The duration of quick setback and the forward shift will be changed.
Entry:
Increase: Longer setback and forward shift times.
For heavy and well insulated buildings that cool down slowly and that
require longer heating up times.
Decrease: Shorter setback and forward shift times.
For light and poorly insulated buildings that cool down quickly and that
require shorter heating up times.
