Control unit and process for adjusting the heating loops in large area heating systems and to control the adjusted heating loops

摘要

A control system for the room temperature in large area heating systems comprises a feed-line manifold and a return-line manifold and for each heating loop an electrically activated throttle valve. A control-unit automatically adjusts the throttle degree of each heating loop so that the temperature difference between the feed-line temperature and the return-line temperature of each heating loop is the same.
