Nest thermostat - no R wire

Hi, I am trying to replace a Pro1 T701 thermostat with a Nest thermostat. The instructions say I can’t continue because I don’t have an R wire. For my current thermostat, I have a red wire coming from the wall to Rc, then a red jumper wire from Rc to Rh. There is no R wire slot in my current thermostat. 

Can anyone confirm my system is incompatible?

Hi tpmc123, 

 

Thanks for posting here in the Community forum and for showing interest in our Nest Thermostats. Are you located in North America or Europe? What is the make and model of your HVAC system? And please send a photo of your current thermostat wiring configuration so I can take a closer look. 

 

I'll look forward to your response. 

 

Best,

Zoe
