I wanted to use my set back thermostat as a true set back and not as an on/off switch but still had concerns that I might somehow be damaging my P35i. I also have noticed that by using my thermostat as a set back and my stove set to room temp @ 80 degrees my glass stays cleaner.
I called Harman today and spoke with a tech and was advised that I would be risking damage to the control board. I was advised to use the set back as follows; "Use only as an on/off control by setting it to 80 degrees when you want heat and 50 degrees when you do not want heat, then use the room temperature setting for the actual temperature". I was also advised to use the stove temp setting for an hour or so every few days to create a higher burn that would help with any creosote.
