For those of you who aren't computer geeks, the title of this thread refers to a Microsoft program from the 90s in which management decreed that they should be using their own products or 'eating their own dogfood'.
I realized that I had built and sold a bunch of controllers, and that my own house was still running a predecessor with software that had increasingly less in common with the systems I was selling. Time to ingest a bit of dogfood myself. I made the switch in November, and have been gradually cleaning up the old wiring and getting it in shape. Here are a couple of pictures of the new controller in place. It has the version II internals in a hacked-up version I enclosure.
The Variable Speed drive units are for the combustion fan (installed and working), the wood boiler circ (ready to go - next on the schedule), and the bypass circ (part of next plumbing update).
It's been an interesting journey, and it was definitely the right thing to do. I had a LOT of complex control rules written in C on the old controller, and I've replaced all of them with rules using the NFCS control language.
