Wiring for a new Nest E

Bill62
Community Member
  • Installing a Nest thermostat E. With my existing thermostat I have four wires G W Y AND R with a jumper from R to RC. When powered is turned on I get nothing. Instructions say there is no need for a jumper, but I can’t get the Nest to come on at all. Is there a way to fix this are am I out of luck.

Hey Bill62, 

 

Thanks for reaching out. 

 

Yes, a jumper wire is not needed so I want to dig deeper into this. A few questions — are you getting a specific message or a code on your Nest Thermostat E's display? If yes, what is it? Also, could you provide a photo of your old thermostat wires?
