nest learning thermostat wiring

[sweettartz44]

I am trying to set up our new Nest Learning Thermostat & I could really use a little help. Prior to this we have a Bryant thermostat with humidity controls. We had wires going to  ACC+ & ACC-, but I don’t see the option for this on the Nest. Can anyone tell me where they might go?

Thank you so much!

Hello Mandi,

Thanks for reaching out to the Nest Community. I’d be happy to help you with this.

A Nest Learning Thermostat’s star connector 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. 

However, no matter which Nest thermostat you have, you can only put one wire into the star connector, so only one function is supported at a time. Also, professional installation is strongly recommended. You can make an appointment with our installation partner, OnTech, to have a trained pro come to your home to install and set up your Nest products.

Let me know if you have any other questions.

All the best,

Lance
