Circuit for controlling motor-adjustable roof-ventilation arrangements

摘要

Previous circuits are characterised by great cabling outlay in the installation of the motor openers and only equipped with one operating station. The new circuit reduces the wiring outlay and makes possible in a simple and economical manner the parallel operation of a number of operating stations. The circuit is constructed with a microcomputer-supported central switching unit centrally in the ventilation group and one or more likewise microcomputer-controlled operating stations. The connection of the central switching unit to the operating stations takes place via known digital data transmission arrangements.
