I have my panel set up and doing water runs from am esp32.  I have an Rtd temp measurement reading accurately and feeding its measurement into a PID controller. The PID controller appears to be working properly except it remains at 255 output even after passing target. The heating element just stays on because the output is staying at 255.  Any insight as to what I might have set up wrong?

Thanks, 

Jason

Can you email us a screen shot of your PID element?
