Since I reset all of my Pid settings and performed a new autotune a while back, I've noticed that when I have my pid controller in Automatic mode that it's rather "Bursty"- the temp jumps when the element comes on and then it rapidly falls.
When I bump the A-M button, while it's still in Automatic mode (A-M light illuminated) I can see why this is happening - the PID controller is making the output either 100% on or 0% on and nothing in between for some reason.
When I first got the pid it would be a very nice slow ramp and wouldn't overshoot hardly ever, it would vary the heat output and slow it down from 100% as it approached my set temperature.
Now when my Pid is in automatic mode it's output is either 100% or 0% and nothing in between...
Anyone got any ideas what could account for this?
