Changing the Thermostat from Carrier to Honeywell RTHL 2510(5-1-1 Day)

I am trying to replace this Carrier thermostat, with the Honeywell RTHL 2510 (Honeywell 5-1-1 Day Programmable Thermostat).

My major confusion comes with one wire.

Red goes to Red.
White goes to White.
Green goes to Green.
Yellow goes to Yellow.

White about the Blue wire in the middle that goes to the "C"?? What would I hook that up to?

I believe that, if you check the instructions, the blue wire is not used on your new thermostat. You can tuck it out of the way. It is a common or ground wire and does not have any voltage. Do not cut it off, because someone in the future may need it for the next thermostat.
