What is the oven controller good for?
Furnace controller. It controls the heat and A/C throughout the house. Running central air on tilt switches is a fast path to a blown compressor (I'm on my second, but this one has a 10 minute delay on it, which is inefficient). Plus my existing thermostats have a hysteresis feature that works well in heating season, but it's backwards in cooling season - the A/C stays on for only a few seconds sometimes. Plus, it runs the A/C even when it's cold outside.
All in all, I needed something smarter. The main board replaces the relay board in the furnace, the little boards will go into new thermostats, and I have a small PC that will connect to it all and control it.
You're doing all that work coming up with the ultimate homebrew control system, then you're gonna use a PC to control it? DJ, DJ...Sigh. ;)
