Nest thermostat

[Srmark]

My existing thermostat only has an R wire, do I connect that to the RC or the Rh?

If you have a heating and cooling system, then you should hook it up to the RC. If you only have a heating system only, you can go ahead and hook it up to RH.

HI Srmark, 

I wanted to check and see if you managed to see the information that CoolingWizard has shared. Also, here are some helpful articles that will help you set up your Nest Learning Thermostat: 

• Install your Nest thermostat
• How to set up your Nest thermostat
• How to add your Nest thermostat to the Nest app   

Please let me know if you have any questions from here. I would be happy to assist and make sure you are good to go.

Thanks for your help, @CoolingWizard. 

Best,
