Wiring a Noma Programable Thermostat

I tried to install a programmable thermostat but I forgot to mark the wires when I disconnected the old thermostat. The air conditioner works fine, but the heating doesn't work. Find below the present hook up. Can someone help me out?
At the furnace I have:
R- Red wire
W - nothing is hooked up to this
C - Black wire
Y - White and Yellow wire
G - Green wire

At my thermostat I have:
G - Green wire
R - Red wire
Y - Yellow wire
W - White wire
Black wire not hooked up.
and I have another black wire that is not hooked to anything. I believe the black and white are the power lines.

Can anybody help me out on this one?
