Abstract

One embodiment monitors the temperature of a space in which an aerosol-forming substrate is located, in order to heat the aerosol-forming substrate and, when the heating of a second aerosol-forming substrate newly inserted in the space begins, a current compensation value is calculated on the basis of a change in the temperature of the space, a compensation current profile is generated by adjusting an initial current profile on the basis of the current compensation value, and a current supplied to a heating part may be controlled on the basis of the compensation current profile.
