OK, here is a much better solution without ripping walls down or ugly
black power connectors running up your wall. Google sells this and it
installs on your zone valve to feed the power to the thermostat. Just
bought one.

This makes no sense. Why would I buy a thermostat where I need an ugly
plug in transformer wired to it? Break out the wall behind it? Im
returning mine. I have two learning thermostats on the same system with
no C wire. Go figure. Buy cheap get cheap...
