I've finally got my rig up and running, it's a 10 gal 240V system, currently RIMS but will be switching to HERMS. It was originally built by someone else for BrewTroller, but I switched to Brucontrol (zero regrets there). I'm running Brucontrol on a Mac with VirtualBox, it's working nicely.

I cannot figure out how to tune the PID algorithms. I've read all the background material, I've tried quite a range of values, and the system seems to consistently settle 30F above my target. 

Here's the rig:

Here's the latest RIMS PID config:

And here is the result:

Any thoughts would be appreciated.

That is odd. Do you have an linear offset calibration set up anywhere in the sensor or PID?

I figured it out, I misconfigured the 1-wire temp sensors.
