Hi- I’m going to give you the same reply I gave to @Will3478 a few min ago. I edited it to accommodate your photo.

It looks like it. You need to match the wire letters on the old thermostat to the Nest thermostat. Attach each labeled wire to the corresponding letter slot on the Nest.
TIP: AS YOU REMOVE EACH WIRE FROM THE OLD THERMOSTAT, use small sticky labels to label the wires with their letters (e.g., W1, Y1, etc. then take a photo after the old thermostat is removed of the wires with the sticky labels attached. Then insert them into their corresponding letter slot on the Nest Thermostat, removing the sticky labels as you go. It should be that simple. Any wires not used should not be used on the Nest, either.
In your photo, you have wires going into slots for letters O and B (this is a heat pump on the Nest). I believe both these wires should go into the joint slot on the Nest.
YyThere are also YouTube videos you can use to guide you. Your current system does not appear to have complicated stuff like multiple auxiliary units (humidifiers, etc), nor multiple ACs strung together. If you have multiple ACs/heat pumps, it’s far simpler to dedicate a Nest to each and operate on a zone basis in your home. But only if you already have separated thermostats for each system“

PS: Honeywell Thermostats are pretty straightforward conversions to Nest. Even older ones.

Hi- @CoolingWizard posted this link in response to another question. It is a thermostat compatibility checker. It looks like a great tool. He seems to be a great, terrific resource: https://store.google.com/intl/us/widget/compatibility/thermostat/

@Kaseyparamore ,

Your system is a Heat Pump system with a Forced Air electric furnace with auxiliary heat strips.
Your wires in use are:

R, Red Wire, This is 24VAC Power Input,

B, Blue Wire, This is 24VAC power Common.

W, Black Wire, This is for AUXillary Heat

Y1, Yellow Wire, This is the Compressor Relay

O, Orange Wire, This if the heat pump changeover valve relay

G, Green Wire, This is the indoor blower fan relay.

Your system is compatible with all Nest Thermostats

1.Nest Thermostat

2. Nest Learning Thermostat

3. Nest E Learning Thermostat.

The Nest Thermostat compatibility help page directs us here to upload a photo via chat. I'm assuming this is the chat. I have a Vive Thermostat TP-S-855C, with a 16 seer Rheem Electric AC/Gas Furnace with a 2 stage compressor. I got a Nest Thermostat for free from the electric company. Is it compatible? I am trying to upload the image of my current wiring setup, but it will not let me. Mine has wires connected to: C, W/E, W2, RH, G, Y, Y2 and a large, red jumper going from RH to RC. Thank you.

Okay, it made me make a username before I could submit a photo. Here it is:

@kingsdaughter44 , yes you have a 2-stage Heating and 2-Stage cooling. You will need a Nest Learning Thermostat. The basic Nest Thermostat cannot handle 2-stage of heat and 2-stages of cooling.

I tried installing Google Nest Thermostat, however during install process I was told it was incompatible. Please tell me which thermostat to use, and if I need to not install certain wires. I have the following wires with my heat pump Y2, X2, F, W1, Y, G, R, and B.

I have a gas forced air furnace and A/C with a Honeywell thermostat. Is the blue wire common on the Nest? Does the R wire go to Rc or Rh on Nest?

Re: Help nest thermostat compatibility photo

CoolingWizard — Sun, 01 Oct 2023 05:26:52 GMT

@PAMTB , The blue wire on your old thermostat is the Common and goes to C on the nest. The red wire goes to R or Rc on the nest Thermostat. The yellow wire goes to Y1. The white wire goes to W1.
I hope this helps.

Trying to find out if my setup is compatible with Google Nest Thermostat. I have only heating, no A/C.
I don’t see an option to upload a photo… so I’ll just mention the wire colors I have

white, red, blue, green, orange, black & brown

I hope that’s enough information

@B15 , which color wire is attached to which thermostat terminal by letter.

CoolingWizard — Mon, 16 Oct 2023 00:05:31 GMT

@TX2023 , your current thermostat is controlling a Heat Pump with 2 Stages along with Auxiliary Heat and Emergency Heat. You will need a Nest Learning Thermostat 3rd Generation to support your system. The black wire on the F terminal is usually a Heat Anticipator wire and will not be needed. You need to repurpose the Black wire as your Emergency Heat. This will require you to open the indoor air handler and find the thermostat cable and locate the Black wire, then connect it to the same location the White wire is terminated on.

@kingsdaughter44 , your free Nest thermostat form the electric company is not capable of supporting 2-stages of heat and cooling. You will need a Nest Learning Thermostat 3rd Generation to support your system.

I am trying to see if my system is compatible with nest thermostat. We have heating only with W and R wires connected.

Re: Help nest thermostat compatibility photo

CoolingWizard — Tue, 24 Oct 2023 19:30:58 GMT

there is a possibility that your system is compatible. You have only a heating system and as long as that heating system uses a 24 Volt Alternating Current powered control system, you can use a Nest Thermostat. Can you access your Heating system and take a few picture of the furnace system making sure that you can see where the thermostat cable connects to the furnace in a picture?

I'm not able to post photos on this thread for some reason but I have attached a google drive link HERE with all the photos I have of our system.

Thanks
