Extra wires on installation

KHALES84 — Sun, 10 Jul 2022 21:12:25 GMT

I'm installing a Nest Thermostat and my old system has a few extra wires, such as two R wires and two W wires. What do I do with those?

Hey KHALES84,

Thanks for reaching out and for the photos.

There's no need for the jumper wire connecting the RC and RH terminal as our Nest thermostats don't use them. As for the W2 wire, connect it to the */OB terminal and you should be good to go.

Hope this answers your question.

Best,

Melba
