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. ;)
