I sent the two Tower of Power controllers back to Blichmann last week, and I recently heard back from Doug, who confirmed that the programmable units inside the controllers were toast. The cause was most likely a short in the data cable, because the odds of two controllers suffering this same fate all on their own are extremely small. According to Doug, these are the only two that have had this problem since the release of the Tower of Power. Blichmann replaced the PIDs and sent the units back, complete with a new data cable.
I’ll test the units out as soon as they arrive. I’m looking forward to having full functionality again and will put them to a test next weekend when another brew day is upon me.
