Abstract (en)
The method is for circulation control in hot water circuits, whereby in each return path (12) the temperature of the hot water in the return branch is measured and regulated as an actual value, a temperature set value of a control box is predetermined, and the measured temperature actual value through a temperature sensor and the predetermined temperature set value are compared in a valve control unit, and in the event of an exceeded negative deviation the actuator of a 2/2 directional valve is acted upon for the opening of the throughflow through the return path. An independent claim is included for a device for the carrying out of the proposed method.
