Nest hermostat Installation

I'm trying to wire the 3rd generation nest learning thermostat.  My system has two blue common wires both are in the same spot labled B, two white wires labled GL and W, two red wires labeled R and Y and two green wires labled GH.  The other  green one is cut off.  I'm doing this for my boss who's bedridden so he'll be able to control the temp himself.
