Nest Compatability - not the Nest Learning

[ecummins]

Hi, my system is a standard Honeywell controlled dual fuel heat pump system. 

The Nest Thermostat only has 6 connections - Y, C, W, G, R, OB*  

My system has Y1, Y2, G, C, W, W2, RC

Need help, believe the learning thermostat has all the connections but not the 4th Generation Nest.

Please advise ASAP, thanks.....

Correct, your system is only compatible with the Nest Learning Thermostat, 3rd Gen

Post a picture of the original thermostat's wiring and I'll show a how to wire it
