I guess you mean motorised window blinds or shutters. I find your description difficult to follow.
Normally these have a control panel with 2 buttons marked up and down.
A long push (maybe this is your 5 seconds) sends the blinds to the end (either fully up or fully down depending on which button was pressed), continuing even after the button is no longer pressed.
A short push simply stops the blinds, if these are currently moving, then moves them only as long as the button is held, in the direction of the button. If held for longer that 5 seconds, again this is treated as a long push.
How does your scheme differ from this, if at all ?
