Menetelmä ja laite lämmitysjärjestelmän ohjaamiseksi

摘要

A method is provided for controlling a heating system, wherein the energy consumption being charged based on spot prices, the method comprises: receiving temperature information; maintaining energy consumption information and degree day information of a first time period. The method further comprises receiving spot price information for the energy; defining an energy consumption parameter using the energy consumption information and the degree day information of the first time period; defining degree day information of a day using the temperature information; determining daily heating energy consumption using the energy consumption parameter and the degree day information of a day; determining a heating time needed to achieve the daily heating energy consumption; defining the heating time with a start time and a stop time; and selecting the start time to optimize the heating time taking place during lower spot prices based on the spot price information; and activating a heating source of the heating system based on the selected start time.
