Daikin Heat pump

[melika]

Has anyone gotten a Nest Learning Thermostat (or even a regular one) to work on a Daikin Heat Pump (unusual wiring)?

Hi @melika,

Thanks for reaching out! I'd be happy to help you figure out if the Nest Thermostat is compatible with your system.

To assist you best, it would be helpful if you could share a photo of your thermostat's wiring. Additionally, you can check our compatibility checker to see if your Daikin heat pump is compatible with Nest thermostats: Compatibility checker.

Please keep me posted!

Best regards, 

Jenniffer

Hi again! @melika,

Thanks for the photo provided; I'd be happy to help you with your compatibility concerns!

We're happy you're considering Nest Thermostat. I noticed the numbered labels on your photo suggest a proprietary system. Unfortunately, Nest Thermostats are not compatible with these systems, as they typically only work with thermostats made by the same manufacturer.

If you prefer, you can contact a local professional to see if your proprietary system can be rewired to be Nest compatible.

For more information on thermostat wire identification, refer to this article: Identify a thermostat wire.

Let me know if you have more questions.

Best regards,

Jenniffer
