JBJ ATO - which "mode" do you use?

I have never heard of the timer fail. The timer shutting down the ATO is more of a problem than it not shutting down the ATO.

BTW, a solution suggested for resetting the timer is to connect the ATO to a timer outlet that will turn it off and on at least once a day to reset it. with that solution, I can see adding the second sensor upside down will make more sense, in case sensor 1 is really stuck.

I think that's a great idea regarding the timer outlet. I think I may do that for added security if I go on a trip. Thanks for posting!
