Abstract: A control system controls a fluid distribution system that includes consumer branches arranged in parallel. Each consumer branch includes a consumer element (31) consuming fluid and/or thermal energy, a regulating device (9) receiving a control value regulating a flow of fluid and/or thermal energy through the consumer branch, and a sensor (11) providing a measured value of the consumer branch. The control system includes a saturation calculation module (21) providing a saturation value, for each operational consumer branch, indicative of the saturation degree of the associated consumer branch, and a saturation compensation module (23) receiving the saturation values and altering a reference value. The altered reference value is based on an initial reference value and the saturation values from all consumer branches. The consumer branch regulating device, of each operational consumer branch, is controllable based on the altered reference value and the measured value of the associated consumer branch.
