Abstract
A method of emitting a volatile material includes the step of programming a volatile material dispenser to include at least two intensity levels, wherein upon initiation of each of the intensity levels for an operating cycle, a resistor is operated at a first percentage of its power rating for a first period of time. Upon selection of a first of the at least two intensity levels and after the first period of time, the resistor is operated at a second percentage of its power rating for a remainder of an operating cycle. Upon selection of a second of the at least two intensity levels and after the first period of time, the resistor is operated at the second percentage of its power rating for a second period of time and, after the second period of time, operating the resistor at a third percentage of its power rating for a remainder of an operating cycle.
