Abstract
Abstract The present invention relates to methods and apparatus for establishing and controlling thermal systems wherein sensing means may anticipate or log temperature conditions at other points, such as at the work or loads and wherein the controlled heating means are related to the thermal capacity of the system. The simulation of load temperature, regardless of presence of anticipation, is obtained even under varying load conditions.
