Default Re: 3 2000W in a 4x4x6?

I need to know what PID you're using so we are talking the same language. Most will have three sections of user definable parameters. One for setup, one for control and one for temperature values. I need you to step through the three sections (addresses) and list all the setting values that are currently stored and their description.

You shouldn't be getting such a wide range of temperature fluctuation, even without a fan. I suspect a problem with the thermocouple (TC) if you ran the auto tune correctly. Is TC connected directly to the PID without any intervening junctions or connecting blocks? Are the connections tight?
