Beyond connecting the wires, you'll need to configure your nest to handle the humidifier. If you have a single wire to control your humidifier, it goes into the star terminal. You can configure it in the equipment menu on your thermostat. You'll likely need to enter pro setup.

I have a 2nd gen nest on main floor, two generalaire humidifier, 2 furnace and 2 thermostat. However, both humidifer wire comes out of the wall on the main floor. How could i connect two humidifier into 1 nest? Plug both cable into *? I tried to contact the local pro installer, but they charge 100 bucks just to come out. If yours only uses 1 wire, good news, you can easily and quickly hook it up to the nest. But most utilize 2 wires, much like a light switch, where a low voltage signal travels up one wire, the humidistat acts as a switch, closing the circuit for the voltage to travel down the second wire back to the humidifier to signal it should turn on. Note that the nest thermostat e controls a humidifier. It's however strongly recommended that you seek professional help during installation.
