Exchanging a silver to black thermostat for Nest Learning Thermostat

[HeidiP21]

Hi, Our heating company installed a Nest learning thermostat and by mistake we were sent a silver ring and wanted a black ring. We purchased another Nest with a black ring and want to remove the silver ring, replace with the black ring. When we remove the silver ring and replace with the black ring the system turns on and then a message on the display states it's turning off. We tried a reset with the silver ring before removing and replacing with the silver ring but that also didn't work.

The silver ring and the base have different serial numbers so it doesn't seem like there is a dedicate coorelation.

The hope was not to rewire just to exchange the color of the thermostat ring from silver to black. We would also plan to return the brand new silver thermostat ring with the new wiring/in the box from the black thermostat ring.

Thank you!

If you are swapping the entire unit (pulling it off the base and putting black one on the base) it needs to be setup for the type of system you have.

It will ask you questions about the wiring, and if you have a heat pump, forced air, gas, or oil heat, etc etc

Basically its like installing a new unit from scratch.

Here are the steps performed and still unsuccessful

1. Silver - reset/removed

2. Black put on base, power's on, will not get to the setup screen , only powers off

Do you see a wire on the C terminal on the base?

If no then use a micro USB cable and phone charger to charge the new Nest for a few hours then try it again on the base.

I ended up researching online and chose to charge the thermostat for a few hours per the recommendation. I have about another hour to go and will try again. It is unusual for a shrink wrapped/brand new Nest thermostat to arrive in box without a charge. This was purchased from Costco which is a high turnover retailer

Hi folks,

@Houptee, thanks for the help.

@HeidiP21, how's it going with your Nest Thermostat? Were you able to charge your Nest Thermostat? Please let us know the results.

Thanks,

Hello Edward, 

What learned and wanted to share with our community. When you purchase a Nest its best to connect a plug to it and the USB side to a computer/device and allow to charge for several hours.  Once was fully charged the device worked perfectly. I also charged our second Nest(to the other system) in our house for several hours and seems to work better than when was just connected and not charged. My observation is that if the Nest thermostat is drained and you connect it doesn't work as well than if you charge the thermostat prior to using.  Thank you!

You should check the Power Status on both your Nests to see if you are getting correct power from the R and C wires. This keeps the Nest powered and charges the battery too.

Watch this video and let us know what your power levels are for each reading like he shows in the video.

The HVAC systems were professionally installed. They are coming back tomorrow to replace an outdoor light damaged and a UV light. I will have them check the R and C wires. I agree with your recommendation, however, one Nest Thermostat would not work, and the other seemed off until charged. Thank you. I will reply tomorrow after the company rechecks. I will also watch the video and ask the service technician to view as well.  Thank you.

Hi HeidiP21,

Thanks for the response. The power readings look fine. Did the Nest Thermostat stay on?

Thanks,

Edward
