Abstract
A heating system is controlled in response to the external temperature in accordance with a heating curve in which the external temperature is related to the advance heating temperature of a fluid used in heating the space. According to the invention, the heating curve is optimized automatically by approximating it with a heating curve equation having at least one parameter which is calculated at least in part from measured instantaneous values of the advance heating temperature, the external temperature or the room temperature, or values representing temperature differential such as the difference between the external temperature and the room temperature and the difference between the room temperature and the advance heating temperature. From these values, a parameter of the heating curve equation is calculated by an estimation method, e.g. recursive or nonrecursive least squares, and the thus calculated parameter is introduced into the heating curve equation to establish the new transfer function of the control system.
