Replacing a trane thermostat with a nest learning

[rguthrie01]

I wired the nest learning thermostat the same way my trane thermostat was wired. Everything i turn it on to cool, the unit blows heat.

@rguthrie01 , please post the picture you took of the old thermostat wiring before you disconnected it. Secondly, post a picture of the Nest thermostat backplate so we can sef the wires attached.
