Did you check for a small car type fuse inside unit?http://i.imgur.com/kYe4Epz.png
I am not showing a fuse in your wiring diagram of unit so first step is going to be to take a volt meter and check between C and R at thermostat and at the red and blue control wires leaving furnace to see if we have 24volts ac at either.
I have to leave for the night .I will open to other experts so you do not have to wait.Will check in tomorrow to see if you got this solved.
I am in office today if you still need help.I see no one was able to help while I was gone.
