Love mid afternoon naps!
The Sleep function is a personal preference, but the device should not keep asking if a new coil was installed after coming out of a snooze – unless of course a new coil was installed!!
The board continually refines the resistance over time. This allow it to adjust to the environment for a more accurate vape (not in those words, but the general idea). If the mod notes a significant change in resistance from the last use it figures it's gotta be a new coil, because the old one would never change that much, right? (board voice) If it's different by less it can't be so sure and may prompt you if your want to use the same resistance as before, or update it. That's what it's really asking for with a new coil prompt. You can of course lock the resistance, but then you lose the whole refining thing which is good to have, or you can go into eScribe and change the defaults on when to prompt for a new coil. NOTE: if you make changes be aware that when you do change coils in the future you better make sure to resample the resistance yourself or it will get very wonky on you.
I've never had the problem you describe, and I can't recall what the default is supposed to be. Best bet is to head over to the Evolv forum and ask around so you don't reset anything outside the envelope. Then again, might not be that simple in your individual case, but possibly a funky connection to the mod, so recheck and clean the 510 connector on the mod and tank as well as the grub screws before tackling advanced electronic TC software programming, even if you did sleep in a Holiday Inn last night.
