Control manner of the heating system which does not depend on the control unit, the heating system, or the engine for the heating system which does not depend on the engine

摘要

The invention relates to a control device (12) for an engine-independent heater (3) that heats a liquid HEAT transfer medium of a HEAT transfer medium circuit (1) especially for motor vehicles. Said control device (12) reduces a heater (3) capacity when an actual temperature gradient ((dT/dtIst) of the HEAT transfer medium is equal to or exceeds a temperature gradient threshold value ((dT/dt) Schwell). The control device (12) determines the temperature gradient threshold value ((dT/dt) Schwell) dynamically in accordance with a difference in temperature (Deltaphi) between a target temperature (phiSoll) of the HEAT transfer medium and an actual temperature (phiIst) of the HEAT transfer medium. The invention further relates to a heater (3), a heating system (1), and a method for controlling the inventive heater (3).
