Hi @annettegl,
Thanks for reaching out here in the community! It seems like you're experiencing a sudden and complete disappearance of your A/C settings, both on your app and directly on your thermostat. No worries, I'd be glad to help you get control of your air conditioning again!
To better investigate this situation, I’d like to ask for the following information:
- What is the specific model of your thermostat? Here’s a helpful article about how to identify your thermostat model.
- When did you install the thermostat?
- When did the thermostat last control the AC?
- What type of HVAC system do you have?
- Can you send a picture of your Nest thermostat's current wiring, and if possible, a picture of the wiring from your old thermostat?
I look forward to your response so we can troubleshoot this further.
Best regards,
Jenniffer
