Hello Donghwan,

Thank you for reaching out regarding the issue with your Nest Thermostat. I understand the inconvenience you are facing with the red dot blinking on the screen, and I'm sorry for any disruption in your heating system.

To assist you further, we recommend the following steps:

1. Try restarting your thermostat by removing it from its base for about 10 seconds and then reattaching it. This simple reboot can often resolve minor glitches.
2. Ensure that your thermostat is receiving power. Verify the wiring connections to make sure everything is securely connected. If there's an issue with the power source or wiring, it could be causing the problem.
3. Check for any wiring reports or message codes in the settings. This would help us diagnose a specific problem.
4. If the issue persists, you may consider performing a factory reset. This can be done through the settings on the thermostat. Keep in mind that this will erase your current settings, so be prepared to set up your thermostat again.

Let us know how it goes.

Best regards,
Mark
