A method for controlling a heating plant as well as a control system for such a plant. More specifically the invention relates to the control of a heating plant adapted for local heating of surfaces to avoid ice and snow on such surfaces, and in particular controlling street heating plant or point heating plants (for rails), provided with one or several heating elements; so that a low power consumption is obtained. The control system is provided with at least one remotely operated unit (4) adapted to be controlled in such a manner that consumed energy is controlled in dependence of meteorological data representing present and anticipated temperatures and amounts of precipitation. The plant may also include one main station or weather station (10) which is influenced both by signals transmitted at a time depending of anticipated meteorological conditions and signals stating detected temperature and humidity at the weather station itself, and at least one satellite station (7) controlled by remote control only, e.g., via a modem, and then by a signal (16) transmitted form the weather station (10). |
