I don't know if it interests anyone, and I'm sorry to revive an old thread as my first post, but I am currently setting this up exactly as described. I will be incorporating a ToP into my HERMS system, with the probe at the inlet to to Mash tun. As I understand, the PID is configurable with the communications link to a PC. In case anyone is curious, I will report back on my success. There seems to be no information online as to weather this will work, but a common thought.
