Claim:
1. A method for controlling at least one electric heating element of an electrically heated aerosol generating system for heating an aerosol-forming substrate, the electrically heated aerosol generating system having a sensor configured to detect airflow indicative of a user taking a puff having an airflow duration, the method being performed by electric circuitry and comprising: increasing a heating power for the at least one heating element from zero to a power p1 when the sensor detects that an airflow rate has increased to a first threshold; maintaining the heating power at the power p1 for at least some of the airflow duration; and decreasing the heating power for the at least one heating element from the power p1 to zero when the sensor detects that the airflow rate has decreased to a second threshold, wherein the first threshold is smaller than the second threshold.
