Not thinking about the "hybrid" feature now..

But, it looks like it wouldn't be too hard to put the two built-in Tstats in series.
If either one opened, it could shut off the power.

It would be pretty be simple to design a dual safety circuit.
(A redundant backup system that would work in parallel).
So, you would have to have dual failures to get over-heating..

But, nothing electronic is ever 100% reliable. (due to lightning storms).
