Howdy. I think I've gotten my Accentra mostly figured out, but one recurring problem is that when I lower the set temperature too far, the stove shuts off & never re-starts. What happens is that we have the stove set to 70 for over night, but during the day (when everybody is downstairs), we want to turn it down to 65. If you crank it down in 2-3 steps over the course of an hour (so that the fire never goes out), it works fine. BUT, if you just turn it all the way from 70 to 65, the stove shuts off (like it should) and never re-starts when temperature reaches 65. You have to shoot it up to 67 until it lights, then crank it back to 65 to get it going again. What's going on?
