ABSTRACT:
Operation of movable members such as wing or sash parts of openable windows or facade sections forming part of a natural ventilation system is controlled by communication of operating commands from centralized and/or distributed control means to operator units for movement of said movable members. Concurrent operation of operator units of a sub-group (1, 2, 8–11) of operator units (3) associated with a single movable member is coordinated by interface means (6, 7) interconnected between the sub-group and the centralized and/or distributed control means (4, 16). The interface unit (6, 7) communicates an operating command from said central and/or distributed control means (4, 16) to the operator units (3), receives actual position and/or status information from each operator unit (3) of the sub-group and uses this information for communication of coordinated individual control commands to the operator units (3). Communication between all operator units of the sub-group and the interface means is effected on a single communication line.
