The sash may slightly over-run past the calibration points, when the sash motor drive is
set to a fast speed. When calibrating the sash positions, allow a margin for the sash to
over-travel past the calibration height.

by 5 mm, or before calibrating the middle position, open the sash to the normal height
and then lower it by 5 mm.
