Can't set up

Just installed a new Nest thermostat.

Power turned back on; I have a little blinking red light at the top of the dial. 

Nothing else.  Have rotated dial, pushed face of unit. Nothing.

I connected four wires:

- Red wire to Rc

- White to white

- Green to green

- Blue wire to Y1 (which agrees with the old Honeywell round...)

Thoughts?

@JeffBV , your thermostat base is actually not fully charged at this time and there does not seem to be a common wire to allow it to be charged by your system. One of things you can do for now is remove the display and use the USB port on the back of it and fully charge it for four hours or more longer. This will allow you to finish the installation process with a full charge battery. The next problem we want to solve is we want to get you a good common wire so it remains properly charged throughout its life
