Setting up PID with a TC4

[Erichimedes]

Hi all, and thanks so much for your work on Artisan! I've used it for years to log/control my roasts via alarms but I want to try to set up PID control with the new features in 3.4. Roaster is a self build fluid bed, with a TC4 that connects heat and fan control from the roaster to Artisan. I'd like to control Environment temp.

The problem I'm having is there seems to be some kind of issue when I turn on PID, as it just usually locks up at 25% heat power. It seems to do this when the I value goes to 100. No idea why it's doing that, and if I turn it off, then back on, the I value doesn't reset, it just stays wherever it was. Here are my settings:

Shoot, In this photo it shows Mode: Background. That was just something I tried, the issue was happening when it was in Mode: Manual
