A method is disclosed for selective alteration and control of door movement modes utilizing an apparatus that is primarily non-hydraulic and incorporated with a known mechanism which is functional independently from the apparatus in one mode of operation and which includes a piston for controlling door closing characteristics by selected fluid flow within the mechanism. The apparatus includes a motor driven lead screw having a linearly movable shuttle unit mounted thereon, the shuttle unit being positioned relative to the piston of the mechanism to accommodate nonattached contact with the piston to urge the piston, when the shuttle unit is moved, in a direction that will at least provide selective assistance with door opening in another mode of operation. Operation of the apparatus is controlled by programming of a related controller including non-volatile memory.

[ What is claimed is:] [1.] A method for learning, storing and controlling operational parameters of a door in conjunction with electromechanically influenced operation of an independently operable mechanism connectable with the door and including a piston for controlling door closing characteristic

[ What is claimed is:] [1.] A method for learning, storing and controlling operational parameters of a door in conjunction with electromechanically influenced operation of an independently operable mechanism connectable with the door and including a piston for controlling door closing characteristics by selected fluid flow within the mechanism, said method comprising the steps of:learning operational variables of a particular door installation without user intervention; or activation andstoring said learned operational variables in memory.
