I have a furnace with an old thermostat that I would like to put a programable thermostat on it. I pulled off the old thermostat and instead of all the wires that are on my new thermostat (C,B,O,W2, W, Y, Y2, RH, RC, G ,A) there is only a red and a white wire on my old thermostat and there are not any labels on it. How do I connect my new thermostat with just a red and white wire?

If you have a two wire thermostat, then you have heat only. No fan/auto and no cooling. Connect red wire to RH and white wire to W1, thats it.
