So, it's one thing for a PID to overshoot the temp until it's tuned to the system. However, I don't understand why it's continuing to fire the element even though it's 10 degrees over the target temp.
It's in Auto mode -- double checked this, and I watched it long enough to confirm it's not on a regular duty cycle. It's somewhat randomly firing for short bursts.
The target temp is 125 and it slowly walked right past that all the way up to 135 over the course of 20 minutes I've been watching it.
I have the probe that's running the PID on the outlet of the kettle before the hose/pump/recirc. I have another probe in a TriClamp port (for testing; it's really a sight glass port) in the side of the kettle that is reading the same temperature.
Is this just a function of running an Auto-Tune cycle? It seems pretty wonky that it's this far off...
Few more details
- It's the SYL-2352.
- I have about 12 gallons in the kettle
- The pump is running full bore; plenty of circulation
...oh, and there's a steak floating around in there for testing It's been over an hour since I started, so it's not the steak.
