Abstract
A controller has an axially releasable locking unit operable to prevent rotation of a regulating shaft from at least one locking position, without first axially moving the regulating shaft. This push-to-turn or pull-to-turn locking unit is arranged entirely outside of a housing of the controller, and is arranged with mounting particulars matched to those of the controller such that the same controller assembly can be used interchangeably either with a push-to-turn locking unit or without such a unit.
