Setting up on older Trane unit (1994) see image attached. I connected the blue wire as a C wire, the rest I sent to their corresponding colors besides T and X2 which I left unplugged.
Seems to work but heat blows cool and air con blows heat.
Electric furnace, outdoor AC unit and feeding into one forced air system.
Thanks for any guidance!!
