So there may be a setting that overwrites this. I can't read the provided files.
So you may have one thing telling the system to not overshoot and another still waiting to reach temp.

You didn't happen to replace a 24v supply with a 12v supply did you? Have to ask
I am not sure where else to look considering each will work on their own.

I start thinking on the lines of broken strands in current carrying DC power wires where you have a very specific localized high impedance zone.
You know what it could be that the original was 24 volt and i put in a 12 volt. That sounds like it could be the problem. Will I need to send it back and get a 24 volt?
