The answer is you cannot connect a RTH2300 to an A/C unit the has WOGRCY wiring?

There must be someone out there who knows the answer to money2004's question. I only ask because I have the same question, although I have not installed the thermostat yet. I really want to be sure that I connect the correct color wire to the correct terminals before I start the installation. I have a 5-wire set-up: W=white, O=no wire, G=Green, R=Red, C=Blue, Y=Yellow.

Honeywell RTH2300 has the following: O/B, Y, RC, R, G, W I believe the correct wire to terminal set-up is: O/B=No wire, Y=Yellow, RC=Blue, R=Red, G=Green, W=White.

Can someone confirm this for me... Thank-you!
