The invention relates to a controller for mixing regulators of central heating systems. The electrical components are arranged on cassettes (4, 5, 6) or their boards which can be pushed into a housing (1) from the front. The parts which can be pushed in have blade contacts at the rear which can be pushed into corresponding mating contacts located in the housing. In consequence, replacement of individual components and hence matching to different electrical operating conditions are simplified. Unauthorised access is exacerbated in that the edge of the front panels (14, 15, 16) of the cassettes is partially covered by a shutter (10) which is rigidly connected to a component (7) which is optionally detachably attached to the housing (1) by means of screws (9). <IMAGE> |
