<div>If you swap out your bad one with one that you know works, and that one works in that location, you know the tstat is bad. I had one fail after 8 years, and I sent it back to HAI for repair. Been working for 3 years since. I would also try cleaning the tstat internally if you haven't already done that. Try it in a different location to see if the problem follows. I remember that you have quite a few tstats in your configuration.</div>
