I just purchased this thermostat and I know I need the c wire but I don't have a c wire spot on my board in my furnace. It s 5 wire setup with a blue wire, white wire, yellow wire, green wire and red wire. I'm not sure I need the blue wire cause I don't have a heat pump. Any suggestions on hook up?

Thanks, Jeff

No disrespect meant, but what do the instructions say?

I believe the "c" wire is the common wire needed to supply power to the unit (I have the same thermostat). If you aren't sure if you have the correct wires, you could call an AC company to come out and check and if needed add a c-wire, or like they did in my case (when I had the new AC installed), just run a new set of AC wires to the thermostat.
