Thankfully he is, took him to the vet to be sure but man was it scary. Walked in to find ambient temps over 110F in the enclosure and it was very lucky that I noticed in time and that Noodle wasn't in those temperatures any longer than he was.
Glad to hear Herpstats have those features! A very worthwhile investment indeed, especially since I've read that other thermostats can have electronic failures after a year.
