The invention relates to a control system for heating installations or the like, with branched-off users or user groups, and is intended to provide a control system in which a considerable saving of energy is achieved by stepless output-matching of the supplied heat output to the requirement at any given time. According to the invention it is proposed for this purpose to provide a primary control of the quantity of heat delivered by the heat generator, for the preparation of the total quantity of heat required for all the users or user groups, in which a stepless control of the main supply pump or pumps takes place, controlled by sensors and measuring equipment, and a secondary control is effected of the fractional quantity of heat to be supplied to the individual users or groups of users from the total quantity of heat, in which control of the addition of feed water coming from the heat generator to the return water flowing back from the heat user takes place by means of sensors (Fig. 1). <IMAGE> |
