Nest Learning Thermostat

[FerristheK]

HELP! Hooked all the old wires to the new Nest but still have BROWN (S1) & BLACK (S2) leftover and Nest doesn’t list those! Where do they go? Thanks!

Post a picture of the original thermostat's wiring.

The S1 and S2 wires are for an external sensor Nest doesn't use or support. You can just tape them off
