First install, not cooling. Nest 3 Learning

[EBasil]

• Okay I followed the installation app for wiring, on a system that was blowing cold when I started, and now that it's installed, it's only blowing fan and not cooling at all.
• I have photos of the old wiring, and the new wiring, although I can't figure out how to upload it here using this interface.

Hi EBasil,

Thanks for posting in the community! Sorry to hear that your newly installed Nest Thermostat isn't cooling. The photos you attached are very helpful, thank you. No worries, help is here! To assist you further, can you tell me what type of system you have? Is it a heat pump or a conventional heating and cooling system?

Keep me posted.

Regards,

Axel.
