Abstract:
1. A method of providing a heated microenvironment within a larger environment, comprising steps of: providing a heating device constructed and arranged to create a heated microenvironment within a larger environment; selecting a low temperature limit at and below which the heating device will be caused to operate at substantially 100% of its rated power; selecting a high temperature limit at which the heating device will be caused to operate at substantially 0% of its rated power; measuring a temperature of the larger environment outside of the microenvironment; applying power to the heating device where the temperature of the larger environment is below the high temperature limit such that the heating device creates the heated microenvironment, the power applied to the heating device being varied with the temperature of the larger environment so as to maintain a continuous heat output from the heating device; and automatically adjusting at least one of the low temperature limit and the high temperature limit as a function of time.
