Nest thermostat heat stage 2 does not heat

[manosek]

It's been working fine for years. Now the heating stops and the dial reads heat stage 2, but I have no stage 2 system. Why would this start happening, and how can I fix it?

Hey there,

Sorry to hear about the trouble. I wanted to follow up and see if I could be of any help. There is a chance you may need to reconfigure your wire setup. You can do that by following the steps here.

1. Go to Settings Factory Reset .
2. Begin thermostat setup with the Home app again. On the main screen, tap Add Set up a Nest product.
3. Re-enter all the wires connected to your thermostat. Double check your account for any unconfigured wires.

Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.

Best regards,
Jake

HVAC guy checked the Nest - all o.k., but wired as if I had a stage 2, which I don't. Furnace regulator failed, new one ordered. Hope it fixes the problem (fingers crossed).
