In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I'm a wet-side guy. But I live in a mid-70's Tri-level house with a furnace. The top floor gets too hot, the middle floor off to the side gets chilly, and the lower area goes from hot to cold. One thing I want to try is running fan 24/7. But I only have 2 wires at the stat, so the Fan On switch does nothing. Do I jump terminals W and G at the furnace to do this? Bad idea in general? I put in anew 93% FAU a couple years ago, but it does not seem to operate the fan at variable speeds. I have no A/C.
