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 (http://yourhome.honeywell.com/home/Products/Thermostats/5-2-Day-Programmable/RTH2310B.htm) 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.
