Abstract

A control device for a radiator valve comprises a housing (10, 12) including an operating, display, control and power supply portion, (14, 16, 18). Said housing comprises a cut-out (24) with which it is slipped-over a motorized drive unit (30-84). When the housing (10, 12) is removed from the drive unit, a reception housing (38) for a motor (34) and a gear unit (36) can be rotated as a hand wheel with respect to a stationary drive housing (32) flanged to the radiator valve so that the valve may be manually operated. A ring (66) being rotatable with respect to the reception housing (38) and a drive housing (32) allows balancing of tolerances and matching to radiator valves of different manufacturers.
