A control unit for an aerosol generating device includes: a sensor that outputs a value related to a temperature of a power source capable of being charged and discharged to a load for atomizing an aerosol source； and a controller configured to execute one or more functions of operating the power source when an output value of the sensor is within a first range having at least one of a first upper limit and a first lower limit. The first upper limit or the first lower limit is smaller or larger than a second upper limit or a second lower limit of a second range that is a range of a value related to a temperature at which the one or more functions can be executed, a range of a value related to a temperature at which deterioration of the power source is suppressed, a range of a value related to a temperature at which the power source deteriorates due only to a factor that is the same as normal temperature, or a range corresponding to an operating temperature of the power source.本發明之霧氣產生裝置用控制單元具有：感測器，係輸出與電源的溫度有關的值，該電源係可充電且可對於使霧氣源霧化的負載放電；及控制部，係構成為：在前述感測器的輸出值屬於具有第1上限與第1下限之至少一者的第1範圍時，執行操作前述電源的功能；其中，前述第1上限或前述第1下限係小於或大於與可執行前述功能的溫度有關的值的範圍、與抑制前述電源的劣化的溫度有關的值的範圍、與前述電源僅因和常溫相同的要因而劣化的溫度有關的值的範圍、或屬於相當於前述電源的動作溫度的範圍之第2範圍的第2上限或第2下限。
