I think I would do some reading on that. Your stat is 12 volt, if you lose power 110 volt you still have 12 Volt running that is what controls your time delay through the stat. If you turn your stat on it will delay but when you lose power 110v. You do not lose 12v which controls your time delay. So as soon as 110v comes back your stat never recognized the lost of power and it would try to start. At Least that is my understanding and it makes sense if if you think about it....
