Hi Jeanpr23,

Thanks for posting in the Google Nest Community forum. I'm sorry for the delay. It looks like you only have a heating system. A few questions: what type of Nest Thermostat do you have? In what country are you located?

You can follow the guide below:

For Nest Learning Thermostat:

• W1 - White (Heating)
• RC - Red (Power)

For Nest Thermostat E:

• W1 - White (Heating)
• R - Red (Power)

For Nest Thermostat 2020

• W - White (Heating)
• R - Red (Power)

Also, here's how you can install your Nest Power Connector.

Best,

Jenelyn

Hi there, 

@Jeanpr23, thanks for getting back to us.

Nest Thermostat 2020 is designed to use very little power, and in many cases they can use your system's heating and cooling wires to get enough consistent power. But you may need to connect a common wire (C wire) or power accessory, like the Nest Power Connector, to make your system compatible. Visit the Nest Power Connector article to learn more. 

I appreciate your help, Jenelyn. 

Regards,

Zoe
