Abstract:
1. A sanitary fitting, comprising: a cold water connection; a hot water connection; a mixed water outlet; a valve device for setting a mixed water temperature and a mixed water throughflow rate, wherein the valve device is connected to the cold water connection and the hot water connection at one end and is connected to the mixed water outlet at the other end; an electrical controller for actuating a valve; and a control signal transmitter for generating an input signal to the controller, wherein: the valve is an integral constituent part of the valve device, and the controller actuates the valve device as a function of the input signal of the control signal transmitter such that a mixed water temperature and a mixed water throughflow rate are set, the input signal includes a positive water quantity signal, a negative water quantity signal, a positive temperature signal or a negative temperature signal as a function of an operation of the control signal transmitter, the controller transmits a signal for increasing the mixed water throughflow rate to the valve device based on a reception of the positive water quantity signal, transmits a signal for reducing the mixed water throughflow rate to the valve device based on a reception of the negative water quantity signal, transmits a signal for increasing the mixed water temperature to the valve device based on a reception of the positive temperature signal, and transmits a signal for reducing the mixed water temperature to the valve device based on a reception of the negative temperature signal, the controller contains a temperature memory for storing a mixed water temperature value that can be set by the control signal transmitter, a mixed water throughflow memory for storing a current mixed water throughflow rate, and a timer, the controller compares a signal time duration of the positive water quantity signal with a positive water quantity time value that is stored in a timer when said positive water quantity signal is received, and if the signal time duration is longer than the stored positive water quantity time value, the controller actuates the valve device such that the mixed water throughflow rate, at an at least approximately constant mixed water temperature in line with the mixed water temperature value stored in the temperature memory, is continuously increased until the end of the positive water quantity signal or at a time at which a maximum permissible mixed water throughflow rate is achieved, and, after the mixed water throughflow is continuously increased, the current mixed water throughflow rate is preferably stored in the mixed water throughflow memory.
