Nest Thermostat N262

[Bonanza]

How do I clear an N262 error on my Nest Thermostat.  It's due to a 7-day extremely cold outside temperature weather event.  Restart doesn't solve and battery condition is good.

Hi Bonanza, 

Uh-oh! I'm sorry to hear that your thermostat is showing an N262 power error. N262 power error means that a C wire is recommended for your thermostat (unable to perform power sharing, possibly due to extreme cold, short cycle, etc.). Does your thermostat have a C wire connected to it?

Keep us posted.

Best,

Zoe
