Hello I have 7 wires. I’ve read the previous posts but I’m not sure what to do with my brown wire U1.

Hi Chatilamr,

Thanks for posting. I'd love to know more about this. Could you share a photo of your current HVAC's control board? Also, what is the make and model of your HVAC system?

Thanks,
Mel
