FIELD: electricity.
SUBSTANCE: group of inventions relates to an electrically controlled aerosol generating system and an electrical circuit therefor, as well as a heater assembly, an electrically controlled aerosol generating device, a method for controlling power supply to an electric heater and a computer-readable data medium. Electrically controlled aerosol-generating system comprises an electric heater comprising at least one heating element for heating an aerosol-forming substrate, power supply unit and electric circuit connected to electric heater and power supply unit and containing memory device. Electric circuit is made with possibility of: measuring initial electric resistance of electric heater; measuring subsequent electrical resistance of the electrical heater after measuring the initial electrical resistance; determining the difference between the initial electrical resistance and the subsequent electrical resistance; determining an unfavourable condition when a certain difference between the subsequent electrical resistance and initial electrical resistance is greater than the maximum threshold value or less than the minimum threshold value stored in the memory; and controlling the power supplied to the electric heater, based on whether the presence of an unfavourable condition is determined, or providing an indication if the presence of an unfavourable condition is determined, wherein difference between initial electrical resistance and subsequent measurements of electrical resistance is constantly monitored to determine, whether this difference between user puffs on the aerosol generating system is less than the cooling threshold value; and, if it is determined that between the user's puffs in the aerosol generating system, the difference is not less than the cooling threshold value, electric circuit allows preventing or limiting the supply of energy to the heater until the difference falls below the threshold value of cooling.
EFFECT: enabling determination of whether the consumable part is "authentic" or is a consumable part which is considered to be compatible with the device by the device manufacturer.
