N262 Error During cold weather in STL

[enriquezx5]

In St. Louis, where it’s cold currently (-2). The is giving me an error that says “install stable power source. g.co/nest/m22”. It also will not connect to the wi-fi. 

Wires connected on the thermostat are: Y, w, r, g

the furnace still runs but not sure what to do about the error. I also replaced the batteries. Any help would be appreciated.

We are in STL too and it’s so cold.  We are getting an n262 error but briefly got the same error as you.  Hopefully someone has something.

Same issue here. It is -9 in Chicago and I got this today

We’re using ours, just set it to hold a temp. How about you?

[Jasoni]

Yes it is working in holding the temp. I will add the power connector tomorrow and see if that fixes the issue

Hi everyone,

Thanks for reaching out. I know it's been a while now — we're sorry for the delay. Please let us know if the issue persists.

N262 code means C wire is recommended (Unable to perform power sharing, possibly due to extreme cold, short cycle, etc.) Adding a C wire or power connector lets the thermostat move its power circuit from an equipment terminal to a dedicated circuit and eliminates symptoms of a power sharing issue. In rare cases, a common wire addresses expected HVAC behavior that interrupts the power sharing circuit.

Most heating, ventilation, and air conditioning (HVAC) systems can power share without a problem, but some may react differently to power sharing. Common wire or Nest Power Connector installation resolves power sharing issues.

Best,

Jenelyn

We’re using ours, just set it to hold a temp as it was cycling off. How about you?

Same issue here in mid Missouri. Has anyone gotten a response yet?
