Those are the exact PIDs I have for both my HLT and BK. I've only run several wet tests so far, and no brewing, but they are fully capable of taking care of your brewing needs. They are easy to program as far as inputs or temp offsets, etc, too. I ran two separate auto tune functions with both PIDs, and they were set in about 25 minutes. It also easily bumps from PID mode to manual mode.
FYI, I didn't have to calibrate my PT100 sensors at all. They were dead on. I also used panel mount connectors on my control panel that you can get from Auber Instruments as well; I highly recommend that.
Here you can see in the upper right corner the panel mount RTD connectors.
Here's a shot of the PIDs in action. Note the temp probes were not submerged in water at the time; they are much
more responsive when submerged.
Hope this helps,
