I am upgrading my thermostat to a Nest, and would like to add a common wire. My current furnace controller doesn't have a C terminal, but the current thermostat wire has 2 unused wires (black and blue)
what's the best way to do this?
On the 24V side of the transformer there is:
1 Red Wire
The difference in quality between bugs that developers write and bugs that testers write is astounding. The newest developer found bug reads: "The message buffer is unstable." and it has a description of "Some quirky things are going on, and it may not be our fault."
That's verbatim, written by a developer who has been coding here for 18 years.
