  • control of the heating section is started in a control mode defined by a heating profile that defines a time-series transition of a target temperature, which is a target value of the temperature of the heating section (step Sp11), acquiring information representing a suction mode in a first period in which the heating section is controlled in a control mode defined by the heating profile (step Sp12);
  • the control mode of the heating unit in the second period after the first period is changed from the control mode defined by the heating profile to the control mode based on the suction mode in the first period (Steps Sp14 to Sp17, Step Sp19 to Sp22), A program that executes processing.
  • the control mode of the heating section in the second period after the first period in which the heating section is controlled in the control mode defined by the heating profile is changed to the control mode based on the suction mode in the first period.
  • the suction mode in the first period is different from the standard suction assumed in the heating profile, in the subsequent second period, the suction actually performed in the first period is taken into account.
  • the heating section can be controlled appropriately. Therefore, it is possible to consume the base material appropriately and provide a high quality smoking experience to the user.
