Nest Thermostat

[Doglegpar3]

Hi guys, hopefully someone will be able to help. 

Just moved into new property. It has a Nest Learning Thermostat gen3 I think. No one knows the 4 digit pin, I can't connect to the app or the wifi, I have no product key and I can't seem to find any information about how to reset the whole unit anywhere online. 

All we are able to do is override the system so we have heat and hot water..

Someone please help.

Assuming the previous owner didn't give you the PIN anywhere, you'll need to reset it using a computer.

1. Connect the Nest Thermostat display via USB to a computer.
   
   
2. Verify that the Nest Thermostat mounts (appears as an attached drive icon).

• If the Nest drive will not mount: Restart the thermostat and the computer.
• If the Nest drive still won't mount: Connect another device to the cable to see if it appears as an installed device.
• If it doesn't appear, use a different cable/port/computer.

If the Nest drive is successfully showing up on your computer, can you see a technicalinfo.PLIST file? If you get this far let me know and I'll ask a community specialist to assist with next steps, as these can't be shared publicly in the community.

So what happened?  I’m having the same exact problem!  I can’t access my Next T-stat because it’s locked  I can’t remember my 4 digit pin!
