Hi Thomas74,

Thanks for reaching out and I'm sorry to hear that you're having an issue with your device. Let's sort this out.

Could you please share a photo on how your Nest Thermostat is wired? What is the power reading on your Nest Thermostat? 

I'll look forward to your response.

Best,

Jennifer

Hi Thomas74,

Thanks for reaching out here in the Google Nest Community.

Based on the photo you've shared, it looks like it is a heat pump. Let's go to settings > equipment > select the right heat type and source. Also, could you verify the white wire on the star (*) terminal is for second stage cooling/heating or for humidifier.

I hope to hear from you very soon.

Regards,

Ryan

Hello,

Think you guys all, the problem is solved, we checked the board of the furnace and found the wrong wiring on it. I am glad the thermostat now is working good!

Best regards to you all!
