As we reported several years ago, Graham ... in the experience of two certified judges for the US Barista Championships, the PID on the Brewtus did not create a noticeable difference in the cup. It' nice to have the ease of moving the temperatures around and KNOWING exactly what is the temperature being delivered (no masking by the controller chip programming), but the temperature swing on the standard controller was a psychological issue, not a taste problem. From a "user experience" perspective, Ken Krone summed it up best: "Ho hum, another perfect cup."
Abe concluded that a far better investment was to switch from a vibe to a rotary pump. But basically, the machine doesn't have any significant performance deficits in home use. A busy shop pulling steady drinks could overwhelm its heaters (... I think we found some tastable impact at around 17 doubles in a rapid sequence and measurable temperature impacts at around 8, IIRC.) Anyone with an urge to PID their machine will find a VERY complete manual on how to do it that Sean Lennon prepared. And BTW, relevant to the wiring discussion that raged here last week, Sean methodically replace virtually all the wire in the Brewtus with heavier gauge stuff and installed a new power cord while we had it apart. Regards, KittJ ----- Original Message ----- From: "BigPappaG" <[email protected]> On another note, does anyone have a manual or any instructions on the PID? I'm curious as to what additional functionality it has. Has anyone successfully increased the pressure of their steam boiler? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Brewtus" group.
