Hello, I'm replacing an ols white-rogers thermostat with a new digital honeywell RTH2300. I have a gas furnace with central AC.

The wires and terminals in my wall are:R-red, G-green, Y1-yellow, W1-Blue, and W2-white.

On the new thermostat the terminals are:O/B,Y,R,G,and W. My question to you guys is which wire goes in the O/B terminal and which one goes in the W terminal. Thanks in advance!

Wrong thermostat.

You need a minimum of a 2 stage heat (W1,W2), one stage cool (Y)

Conventional stat.
