A method of controlling a heat transfer plant having a circulating heat carrier which circulates at a constant rate. By the control method central heating plants can enjoy optimum running as a function of the heat consumed and the problems of the prior art in over-heating or under-heating rooms are avoided. In the method the feed temperature is so regulated as a function of the temperature differential measured between feed and return, that the actual temperature differential is equal to an adjustable desired temperature differential or a desired temperature differential pattern, and in such a way that the lower limit of the feed temperature is limited by a predetermined minimum temperature. |
