Nest Thermostat Compatibility

[Rampantscot]

Hi, I have some old LG wired remote wall controllers which need to be replace. Is a Nest thermostat compatible with there? They have 3 wires, yellow, black red that go into a little white plug thing that is inserted into CN-REMO. This set up is different to any other information I can fine online or on YouTube. I don’t know if it’s some special LG thing! I need to change them because the little display is so dark I can’t see the settings.

Hi there!

Based on the information you've provided, it seems your LG system might have a proprietary wiring configuration that's not directly compatible with standard Nest thermostats.

While Nest offers a wide range of compatibility, specific LG models may require additional components or modifications. To determine the exact compatibility and necessary steps, I recommend:

Consulting the Nest Compatibility Guide: By taking a look at Identify a thermostat wire. You should be able to check the compatibility.

Consulting the Nest Compatibility Checker: By using the next link you should be able to check the compatibility: https://goo.gle/45vY9YW

I'd like you to provide me with a picture of your current wiring.
