Wow. I've been going from the official IFI documentation which says the Victor deadband is 117-137. I never gave it a second thought. But that would perfectly explain the asymmetric PID response I wrestled with a week ago.

I will take a few minutes on Monday to characterize our Victors and see if they show the same center as yours. It'll definitely make a difference if the true neutral really is 132.
