Abstract (en)

[origin: DE102011056865B3] The device has a control unit (7) which controls a heat circulation pump (1) depending on measured signals or control commands. The volume flow of the heat circulation pump is controlled corresponding to the heat demand of connected heat consumers or corresponding to the heat provision of the connected source. The control unit emits an analog input signal from measuring signals and from control commands for the need of drive energy of the heat circulation pump, where the analog input signal is equivalent to sum of measuring signals or the control commands. An independent claim is included for a control method for a device for controlling a heat circulation pump.
