I am trying to install a programmable thermostat Honeywell RTH2310; replacing my exsisting White Rodgers 1E30W-311, but the wiring doesn't match up.
I have a red and black wire attached to my current thermostat, and then a brown, green, orange and blue wire that aren't attached to anything. How do I hook that up to Rh, Rc, W,Y, G set up on my new thermostat?

Do you have the installation directions for the new one? Most often the Rh and Rc get jumpered. Use this RTH2310B | 5-2 Day Programmable Thermostat to find the right direction. Tell us in detail about your current furnace and AC, we need to make sure this is the correct tstat for your app.
