Abstract
A dual temperature control circuit detects a first temperature of a first location and a second temperature of a second location. The dual temperature control circuit transforms the first temperature to a first voltage signal, and transforms the second temperature to a second voltage signal, and compares the first voltage signal and the second voltage signal to output a third voltage signal, where a controlled circuit is controlled according to the third voltage signal.
