Download the Google Home app on a phone or tablet, and follow these steps:
The app will guide you through the setup process, which includes checking off which wires you have and labelling each one with the stickers provided in the box. It will then tell you where to connect each wire in Nest Thermostat.
First of all, how about show a picture of the box and the manufacture label. That looks like a Nest E but I can be wrong. Also, show a picture of the step-by-step instructions that came in the box. Since the installation starts with you taking a picture of your old thermostat, share that picture as well. How to get started:
Turn the power to the HVAC system OFF. Now then, Before removing the old thermostat, take a quick picture of the wiring with your phone in case you need it for reference. Disconnect the wiring and remove the old thermostat. Use the wire labels included in Nest Thermostat Installation Guide if needed.
Next, Install the Nest Thermostat
Run the wires through the center of the Nest Thermostat base and attach it to the wall using the screws provided. Do not use a power drill on the screws. Over tightening the screws can damage the circuitry in the Nest base. For paneling, plaster-and-lath, or if there is a stud behind the thermostat, pre-drill a hole using a 3/32” bit first.
Use the built-in level for proper alignment. Trim or re-strip any wires as necessary and connect them to their corresponding terminals on the base. Make sure the wire is straight and the connector button stays down after inserting it.
If your current thermostat has a C wire, now you can install the display unit onto the baseplate. If you have no C wire, I recommend using a micro USB cable and a charger and plug it into the back of the display unit and charge it up for 24 hours before hooking it up. In fact, I usually tell people to do this before they even start installing the nest leave their old thermostat on for another 24 hours while you charge up the Nest display. by taking this approach, you know the nest thermostat will have plenty of power to do the final installation and configuration steps that will be required.
I hope this helps you to get started, if you have specific questions feel free to ask him here.

Thank you for these prompt replies. Much appreciated. This thermostat was sent to me by our local power company as part of their green initiative. It doesn’t look like typical nest thermostats. It has a mirror front. The box does say nest on it.
I got through instructions in the box to where it says remove existing jumper between R and Rc. Old thermostat does not have an R terminal. I’d include a picture of the old terminals but I don’t see an include picture option in this reply menu.
You have a heating only system. You Nest wires will be:
Red Wire to R
Green wire to G
White wire to W1
once you complete the installation, the screen will respond to a tap on the outer ring. Slide your finger up and down on the outer ring and tap to select an item. You need to download the Google Home app to perform the installation.

To be compliant with all types of HVAC systems. That is why there is an RC and an RH. Most systems are all combined and that’s why there’s a jumper between RC and RH. For most systems, you will place the wire in the nest R connector. Your Nest Thermostat is the basic model. Your back plate will have R, C, G, Y1, W1, *OB.
Place the wire on your old thermostat Rh, or Rc in the Nest R. The terminals R, Rh and Rc are all Power In. What you’re typing your reply you will have an opportunity to include a picture when you tap on the camera and the top edge here.
Think of the power connector is having two sides. One side has three wires, and one side has two wires. The side with two wires are gray color, and one will hook up to the thermostat R wire, and the other will hook up to the thermostats W wire. On the other side are three white wires. One connects to the COMMON, one connect to the R on the control board, and the third one connect to the W on the control board.
When the thermostat is not calling for Heat the power connector will connect the Common to the W. The nest thermostat will take that W and use it to charge the battery.
