From what I read on news group post that where dated back in the early 90's it's a drop in chiller (bet you already knew that ). The thermostat is on the probe and it is not adjustable. The standard config comes with a 76 degree probe. I couldn't any info on that after around '96. They must have gone out of business.
You found a lot more information than I did. I was concerned if I can control it with a newer type controller. I am hoping I can convert it. I am hoping to find the original probe. If anyone finds anymore information, I would love it. I found this thread on the Krib and that was it earlier. I wonder who bought them out. Thanks Gordo, I look forward to returning the favor.
