Brian,
When my grilled reached temp, i noticed i could not maintain temp. Temp started dropping off and never recovered even when the servo showed it was open 50%. Thought maybe the thermocouple was flaky so i changed it. No change. When the temp dipped, servo would open and the fan would show 0% on the graph. So i checked the invert and then when the servo opened for more air the fan followed. the grill would then maintain temp. Then i let it settled for 15 minutes and control was working fine. I decided then to make a tweak to the "I" value from .0032 to .0034 and waited for the change, and 10 minutes after the change the controls went nuts and the temp dropped out and the controller locked up. I rebooted and the controls never really recovered. I reloaded 20200214 and all is working we. Back to normal. I do not need to check invert box for fan. Very interesting. The firmware i was using was the latest from the download page.
