Abstract
A system is provided for generation of a set point for a control or automatic feed back control of the feed line temperature in a heating plant depending on the outside temperature. Usually such set points are entered as heating curves into the controller. The heating curves are in reality nonlinear relationships and are difficult to be processed by a computer. The invention subdivides the heating curve into two straight lines, which meet at a common point. This point is placed where the maximum difference occurs between the heating curve and a linear relationship connecting points corresponding to a minimum permissible lowest temperature and to a sufficient high outside where no heating energy is required. Operation according to the invention saves energy by better approximating the temperature requirements of inside rooms at different outside temperatures and this increases the comfort of the persons staying there.
