Wiring issue

[jeffivy]

My current wiring diagram does not have a white wire connected to the thermostat. It has a jumper wire from the yellow wire connector to the white connector location. What shall I do?

Thanks

Hello jeffivy,

Thank you for taking the time to let us know about your inquiry. I'd be happy to take a look at this for you.

Could you please share with us your old thermostat's wiring setup? Also, what type of Nest Thermostat are you trying to install?

I'll look forward to your response.

Regards,
Mark

Hey there,

I'm checking back in. How's it going? Additional information about the wiring setup: the Nest Thermostats don't require a C wire, so you no longer need to connect it. But you need to double-check your HVAC system control board to locate how the wires are being installed.

Please keep me posted, as I would be happy to take a closer look and assist you further.

Regards,
Mark
