I have Equipment Error e299 on my Google Nest Thermostat- what is it? How can I fix it? It’s 80 degrees in my house

Hi Thartman,

Thanks for reaching out to the Google Nest Community Forum. I'd be happy to take a look at this for you.

You're experiencing a power-related issue with your HVAC system that triggers your thermostat to give you an alert. To check your systems' compatibility with the Nest, could you please share with us your Nest Thermostat's wiring setup and your old thermostat's wiring photo? Also, gather its power readings in the Power Info section under the Equipment settings and your HVAC system's make and model.

I'll look forward to your response.

Regards,
Mark
