I only have two white wires coming from heater. On my old Penn thermostat they were connected to a blue and a red marked connection. Where do I connect these to my new Google thermostat?

Hi @RodK!

 

Thank you for reaching out to the community. I am glad to see that you want to replace your old Penn thermostat with a Nest Learning thermostat 4th generation. It is my pleasure to help you to make the best decision. Before continuing. Would you kindly send us a picture of the wire that is currently on your Penn thermostat?

I'll be waiting for your response; any additional details you can provide will be helpful.

 

Regards, 
Jeremy.
