Hello @sjjshsi_3727
Thanks for reaching out to the Nest community. I'm happy to assist you with your compatibility questions.
To provide the best possible support, could you please share a photo of your current wiring setup? A brief description (e.g., "Blue wire connected to c, Red wire connected to R") would also be helpful.
Additionally, any information about your existing system would be valuable in determining compatibility.
Feel free to share any further details, and I'll do my best to find a solution.
Best regards,
Douglas.
