Abstract

In a method for controlling the service water temperature in a service water system which can be switched between a nominal working mode and an economy mode and whose controller, in the nominal working mode, generates a control signal for a heating means from the difference between a desired value (TNenn) and the actual value of the service water temperature (TBw), a limit value which is lower than the desired value (TNenn) is introduced for the service water temperature, and in the economy mode measures are taken to raise the service water temperature in case the limit value is reached. In a first advantageous variant of the method, when in the economy mode the service water controller uses a desired value (TSpar) which is advantageously at around 40@C. In a second variant of the method, the service water temperature is monitored, and after undershooting a threshold value (TT) the service water is heated until the desired value (TNenn) valid in the nominal working mode is reached or until a predetermined period of time (41) has elapsed. <IMAGE>
