Abstract

The invention concerns a control system for a plurality of groups of lifts (G1-G5), according to which system the passenger can input his destination at any destination call input device (TE) without having to know which group of lifts (G1-G5) serves the desired storey. In this way, in large buildings in which, for structural reasons, the ranges of storeys served by individual groups of lifts (G1-G5) are disposed adjacent one another in a confused manner, the passenger's search for the appropriate lift is facilitated. The multiple groups control system always selects the most favorable lift from all the available lifts and, when the storey ranges served by a plurality of groups of lifts (G4-G5) overlap, the selection is made from all the possible lifts. If the passenger has to change lifts, the connecting lift is shown on a display.
