There is a (•) symbol showing. What does it mean?

Hey All315, 

Thanks for reaching out. 

Are you pertaining to your Nest Learning Thermostat's terminal label? If yes, this can be used to control several different system functions, depending on what type of system you have. For example, you can use the star connector to connect a wire that controls a humidifier or dehumidifier, or emergency heat. 

I suggest that you check on this link to know more information about this star connector: https://bit.ly/2Wt4kvm

Hi, 

I haven't heard from you in a while so I'll be locking this thread if there is no update within the day. If you have any new issues, updates or just a discussion topic, feel free to start a new thread in the community.
