FIELD: heater control.
SUBSTANCE: group of inventions relates to the control of a heater, including: an electrically controlled system that generates an aerosol, a heater assembly, an electrically controlled device that generates an aerosol, an electrical circuit for an electrically controlled system, a method for controlling the supply of power to an electric heater, a machine-readable data carrier for performing the steps of the method. An electrically controlled aerosol generating system comprises an electric heater containing at least one heating element for heating the substrate forming the aerosol, a power supply unit, an electrical circuit connected to an electric heater and a power supply unit and containing a storage device. The electrical circuit is designed to measure the initial electrical resistance of the electric heater, measure the subsequent electrical resistance of the electric heater after measuring the initial electrical resistance, determine the difference between the initial electrical resistance and the subsequent electrical resistance, determine the unfavorable condition when a certain difference between the subsequent electrical resistance and the initial electrical resistance is greater than the maximum threshold value, or less, than the minimum threshold value stored in the storage device. And also to control the power supplied to the electric heater, based on whether the presence of an unfavorable condition is determined, or provide an indication, if the presence of an unfavorable condition is determined, save the result of determining the unfavorable condition in the storage device, determine the number of consecutive results of determining the unfavorable conditions based on the stored results of determining the unfavorable conditions, disconnecting the cartridge or permanently or irreversibly preventing or blocking the supply of power to the specified at least one heating element, if a certain number of consecutive results of determining adverse conditions is greater than the maximum threshold value.
EFFECT: said group of inventions makes it possible to determine drying of the heater or other unfavorable conditions on the heater in an electrically heated system that generates an aerosol, and, in particular, it is a system that can work with different heaters.
