apparently you will not be able to directly replace EcoNet thermostat with Nest in the case if you have a Rheem furnace. They both designed to work together in a unique way.

Hi Adarsh1111,

Thanks for reaching out. I'd love to know more about this. Could you share a photo of your current thermostat's wiring? Also, you could try our compatibility checker to see if your current system is compatible with the Nest Thermostat.

Thanks,
Mel

Hey Adarsh1111,

Checking back in should you still have some questions here. Let us know by replying to this thread.

Best,
Mel

Hi Adarsh1111,

Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.

Thanks,
Mel

I did try compatibility checker, since I got wires like R, C, E1 and E2, I’ll add a picture of wiring at the earliest

Hello there,

 

I appreciate your effort in sharing the pictures of your system panel, @Adarsh1111. However, we can't determine which wire is directly connected to your current thermostat.

 

To be sure, could you also send us a picture of your current thermostat wiring diagram showing how the wires are labeled?

 

I'll look forward to your response.

 

Thanks,

Mark

Please find the updated pic and wiring diagram

Hello there,

 

I'm sorry for the late response. I know it has been a while, but I wanted to ensure that everything was covered here.

 

I appreciate you sharing the photos. The E terminal on your thermostat appears to be for emergency heat. Some thermostats for heat pumps have this terminal, which toggles the emergency heat on or off. With setup, it requires local professional assistance to rewire your system to make it Nest-compatible.

 

If there’s anything else I can help you with, please let me know.

 

Thanks,

Mark

Hi Adarsh1111,


I wanted to follow up and see if you are still in need of any help. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.

 

Thanks,

Mark
