摘要:
Example architectural opening coverings and methods are disclosed. An example architectural opening covering system comprises a first motor to move a middle rail relative to a fixed top rail, and a second motor to move a bottom rail relative to the middle rail and the fixed top rail. The example system also comprises a controller to selectively actuate the first motor to move the middle rail based on a first position of the middle rail and a first position of the bottom rail, and to selectively actuate the second motor to move the bottom rail based on a second position of the middle rail and a second position of the bottom rail.
