How do I upload the wiring image to determine compatibility? The message board says I don't have permission to upload images.

Hello bstellar,

I understand that you're having trouble uploading a wiring image to determine Nest Thermostat compatibility.

To work around this issue, you could try describing your current wiring setup in detail. List the wires you have and their corresponding labels. Additionally, you can provide any information about your HVAC system. 

Here's how to insert an image in a post:

1. Reply to this post.
2. Sign in with your Community profile.
3. Click Insert Image. (camera icon)
4. Choose an image source location.
5. Follow the on-screen instructions.

If you have any more questions, feel free to ask.

Regards,
Mark

Thanks for your help. Here is the image of my current thermostat, which runs a single-zone Climatemaster geothermal heat pump.

any help would be greatly appreciated!

Hi Bernie,

Perfect! Thanks for sharing your thermostat's photo. It appears that you have a heat pump system which is a Nest Thermostat compatible. Here's your guide for the installation.

• Orange wire > O/B terminal. (Heat Pump)
• Green wire > G terminal. (fan)
• Red wire > Rc terminal. (power)
• Blue wire > C terminal. (24 volt common)
• Yellow wire > Y/Y1 terminal. (cooling)
• White wire > W/W1 terminal. (heating)

Also, the Nest Thermostats has built-in sensors and indicators, so you won't need the black wire. Let me know if you have more questions.

Warm regards,
Mark

Thanks so much Mark! Additional question: the builder recommended that the until never be set to “auto”, only either heat or cool (or off). He also recommended that the fan be used all the time with the a/c, but not with the heat. Will those instructions be necessary, important, and, if so,  implementable with the Nest?

Thanks again for your help,

Bernie

Hi Bernie,

You're very welcome! Regarding your additional questions, the recommendations from your builder are worth considering for optimal HVAC system performance. While Nest Thermostats are designed to be versatile, there are a few points to keep in mind.

When the thermostat is set to "heat and cool," it allows the system to automatically switch between heating and cooling modes based on the desired temperature. However, some users prefer more control over the system, especially in transitional seasons. The Nest thermostat should allow you to manually select heating, cooling, or off mode.

Running the fan continuously when the air conditioner is active can help distribute air more evenly and improve air filtration. You can set the fan to run "on" or "auto" in the thermostat settings. However, keep in mind that continuous fan operation may slightly increase energy consumption.

Feel free to reach out if you have more questions or need further assistance. 

Best,
Mark

Thanks again, Mark. I will be installing the nest thermostat this weekend - I’ll let you know how it works out.

Hey Bernie,

Sounds like a plan! Keep me posted—I would be glad to know what the result would be.

Best,
