I am trying to install the Honeywell RTH 230B from the TH5000

TH5000
Rc (nothing in it)
R wire (red)
Y wire (yellow)
C wire (blue)
W wire (white)
G wire (Green)

RTH230B
Rh
Rc
W
Y
G

Where does red go, Rh or Rc, I assume Rh since the direction say that for a 4-wire heating and cooling system. The big question though is what do I do with the blue C wire. Should I just leave it hanging there as an exposed wire? I am afraid that could cause an issue.

Thanks so much for your help.

Corey

Red goes to either with a jumper between them. C will get buged off and shoved back in the wall for future use

Thanks for your help Josh. I know next to nothing about wiring, what does buged off mean?

Thanks again
