SUBSTANCE: invention relates to systems of heat tracing. The method of controlling the heat tracing circuit with automatic determining of interval duration of lack of power supply comprises calculation of the interval duration of lack of power supply based on the value of temperature of the process pipeline, measured at the end of a predetermined initial interval of the lack of power supply, as well as taking into account of the particular temperature of set point for the process pipeline and temperature of non-sensitivity area exceeding the temperature of set point. The set point temperature is determined taking into account the process fluid medium, the characteristics of the heating cable and the operating conditions of the process pipeline. The interval duration of the lack of power supply is limited by the time required for the process pipeline temperature reaches the temperature of set point.
