Inhalation device, control method, and non-transitory computer readable medium

A control method for controlling an inhaler device including a heater configured to heat a substrate to generate an aerosol, the control method comprising:

• measuring temperature of the heater based on an electric resistance value of a heating resistor of the heater;
• controlling an operation of the heater in accordance with a heating profile that defines a time-series progression of a target temperature, the target temperature being a target value of a temperature of the heater;
• and
• measuring temperature of the heater using a temperature sensor, wherein
• the heating profile includes a plurality of time sections that are continuous along a time axis,
• each of the plurality of time sections is assigned the target temperature for an end of each time section,
• the heating profile includes an initial temperature rise section, an intermediate temperature drop section, and a temperature re-rise section in sequence,
• the target temperature set for the intermediate temperature drop section is lower than the target temperature set for the initial temperature rise section being a time section immediately before the intermediate temperature drop section, and
• the controlling of an operation of the heater includes determining an end of the initial temperature rise section and the temperature re-rise section in accordance with temperature of the heater measured based on the electric resistance value, performing control such that no electric power is supplied to the heater in the intermediate temperature drop section, and determining an end of the intermediate temperature drop section in accordance with temperature of the heater measured by the temperature sensor.
