– C second wire from Power
– G fan wire

– Y ac wire
– * humidifier
Set up
For each yellow box you must enter in and set up the proper equipment. When Nest saw it is a wire connected to * will show the humidifier set up option. Usually you set up the humidifier running in the same time with your Fan. Don’t forget this ! The best setting is Hum+Heat. The humidifier will operate only when the heat is on, more efficiently to increase faster the humidity ratio.
Confirmed
After you set up the humidifier you will see confirmation with green on * connection. Humidity level can be set up on your phone or on the thermostat.
