Volatile composition cartridge replacement detection

Abstract:

A volatile composition dispenser and methods of detecting the replacement of a cartridge of volatile composition are provided. The cartridge of the volatile composition dispenser includes one or more reservoirs, with each reservoir containing a volatile composition. A method of volatilizing the volatile composition includes operating the evaporative assistance elements with varying energy over a total emission program. Replacement of the cartridge by a user when the volatile composition dispenser is disconnected from an external power source is detected in order to reset the total emission program when reconnected to the external power source.
