1. A method of dispensing a volatile composition, the method comprising the steps of:
providing a volatile composition dispenser, the volatile composition dispenser comprising:
a cartridge comprising a reservoir for containing the volatile composition,
a delivery engine in fluid communication with the reservoir,
an evaporative surface in fluid communication with the delivery engine,
an evaporative assistance element adjacent at least a portion of the evaporative surface, wherein the evaporative assistance element defines a maximum power output, and
a microprocessor configured to control a temperature of the evaporative assistance element by: starting a total emission program for the volatile composition dispenser at time zero when the volatile composition dispenser is first powered and the cartridge is new or refilled to be full of the volatile composition, wherein the total emission program comprises a plurality of discrete emission periods;
initiating a first discrete emission period by increasing energy to the evaporative assistance element to a first boost energy in a first energy boost period, wherein the first boost energy is at least 75 percent greater than an energy immediately before the increase to the first boost energy;
decreasing energy applied by the evaporative assistance element to a first extended energy;
operating the evaporative assistance element at the first extended energy over a first extended energy period, wherein the first extended energy period includes a period of maintained energy level, and wherein the first extended energy period is greater than the first energy boost period;
initiating a second discrete emission period by increasing energy applied by the evaporative assistance element to a second boost energy in a second energy boost period, wherein the second boost energy is at least 75 percent greater than an energy immediately before the increase to the second boost energy;
decreasing energy applied by the evaporative assistance element to a second extended energy; and
operating the evaporative assistance element at the second extended energy over a second extended energy period, wherein the second extended energy period includes a period of maintained energy level, and wherein the second extended energy period is greater than the second energy boost period.
