I know this thread is old, but I'm wondering if I, having no electronics training, could make a similar controller for my attic fan using the same approach. Any suggestions on how to go about this (or detailed instructions or plans!) would be much appreciated.

My fan currently has a control on it that turns it on when the temp. reaches a certain (hot) threshold, i.e., for summer time. However, I want to prevent ice dams in the winter, so am thinking that if I could make the fan turn on when a) the attic temp is above freezing, and b) outside temp is below freezing.
