Abstract
A method of operating a window having a sash and a window opening limit device includes moving the sash from a closed position to a limited position. When in the limited position, the window opening limit device is in a projected position, and the sash is engaged with the window opening limit device. Moving the window opening limit device to a retracted position disengages the sash and the window opening limit device. The sash may then be moved from the limited position to an open range. When the sash is returned to the closed position, the window opening limit device automatically returns to the projected position, and the sash is disengaged with the window opening limit device.
