checking on existing thermostat wiring for compatibility with Nest thermostat

[rmq]

I have an old, dial thermostat that was installed when the condo was built (2006) that has 2 wires, red and green. The red is connected to the "R". Any chance the Next thermostat could serve as a replacement? Thank you.

Hi @rmq,

Thanks for reaching out to the community forum. I understand that you'd like to know the compatibility of your current system and the Nest thermostat. Don't worry, I'd be glad to assist you. To better assist you, I have a few questions:

• What type of HVAC system do you have? 
• What's your current thermostat model? 
• Can you share a picture of your current wiring installation? 

Any additional details you can provide will be helpful.

Regards,
Jonathan
