My central unit works fine... well it did until I touched it! lol.
I was upgrading to a digital tstat and noticed that the heat-off-cool selector switch was broken.
I opted to put my old one back on and now I can't get the unit to come back on. I'm 99% sure I wired it wrong.
Would you please let me know the correct way??
Here's the current wiring:
oh yeah.. It's a Trane with aux strip heat.
I would guess you probably cooked a fuse in the unit
