Abstract
An apparatus and method for infinitely variable adjustment of temperature range of a device in multiple selected temperature ranges. The method includes providing a plurality of operational temperature ranges of the device, selection of a desired temperature range, and infinitely variable selection of a specific temperature within a selected range. The apparatus includes a temperature range mechanism limiting operational temperature to first and second temperature ranges, and a control mechanism to select one of the first and second temperature ranges and then infinitely adjusting temperature within the selected range. In the example of a clothes dryer, the invention allows the selection of a higher or lower temperature range for the clothes dryer and, once the range is selected, infinitely variable temperature control within the selected range.
