Replacing a thermostat with 10 wires, Y2 (brown), X2 (black), W1 (white), S1 (red), S2 (white), R (red w jumper to RC), O (orange), Y (yellow), G (green), B (blue). Where does the X2 (black)  go?

Hello audioplus,

Thank you for reaching out to the community. Based on your wiring system, most of them are compatible with the Nest thermostat. However some wires may require a professional's help for proper identification.

If you'd like to get better assistance with installation you can contact one of the recommended technicians.

Best regards,

Daniel
