Abstract
An arrangement and a process for controlling the temperature of a medium, particularly of the cooling water temperature of a motor vehicle engine. At least two energy-consuming units influence the temperature to be controlled, of which at least one can be controlled with respect to its output. A control unit adjusts the output of these units for causing a required influencing of the temperature. The output of each temperature-influencing unit is adjusted by means of a previously determined, energy-minimal characteristic diagram K.sub.E which indicates for each system condition the operating point of the absolutely minimal energy consumption of the energy-consuming units for controlling the temperature according to a respective desired value.
