    As a result the furnace runs at stage2 all the time. It has been identified in this thread that this wiring setup will be a problem for running the furnace at stage1.

    As you can see from the Nest tstat pic, there are no jumpers on the Nest wiring:

    Thank you all for your suggestions on thermostats. We're going to run with the Nest for now and research some better alternatives.

    Thanks,

    You may want to reread my post more carefully.

    I was referring to the cooling, Y1 and Y2 being jumpered together.

    without a Common wire the stat becomes a power stealing/robbing type. this tends to lead to issues with some stats and definitely leads to issues with the NEST.

    again, NEST is something that is MARKETED to accomplish something that really is not necessary and can be accomplished by other products already on the market, most of the time less expensively.
