Hi Patch,
what would u like a herms controller to do? with my experiments i just used a pid to govern the heating measuring the return to the tun, and set the pump speed by hand. If you intend to keep an eye on it thats all u need...

employing an underback to pour the tun liquor into to avoid sucking the grain bed down with a pump connected directly to the tun, a float switch could be used to turn off the pump, and perhaps the heating in the event of the liquor dropping below a usable level.

for a more sophisticated controller there is always the arduino community to search for a pre speced and programmed resource to copy
