Wiring compatibility

[Rickyt]

Can you please tell me if my wiring is compatible with any Nest thermostat?

Hi Rickyt,

Thanks for reaching out. Based on the photo, it looks like your current thermostat is using stranded wires. Nest thermostats don’t support stranded wires, they require solid-core copper wires.

If your low voltage wires are stranded (each of the wires is a bundle of smaller wires), reinstall your previous thermostat and contact a local pro to have your thermostat wiring replaced or adapted with solid core wire so it can work with Nest thermostats.

Thanks,

Edward

Hi Rickyt,

It's me again. I wanted to check back in to see if you have other questions and concerns. Feel free to let me know if you do. 

Thanks,

Edward

Thanks.  I'm curious as to why a Nest won't work with stranded wires.  If it's just the connection, that should be easy to work around.

As Edward has mentioned, it is recommended to use a solid-core copper wires for your Nest Thermostat.

Once I’ve converted the wiring to solid copper, how do I hook up this heat pump to a Nest?  What wire goes where?  Thanks again.

Hi Rickyt,

Thanks for the reply.

To help us figure out what wire goes where, there should be wire labels from the old thermostat. We then need to connect the same wire labels to the terminal on the Nest Thermostat.

Let us know how it goes by replying to this thread.
