Setup of a Nest Learning Thermostat

[JRB-FSU]

I have ‘ITEM’ T3017US, and the only mode it has is HEAT, no Cool or Fan.  My system is a Carrier 2 wire system.  Where should the red and black wires be set?

Hi JRB-FSU,

Thanks for reaching out. I'm sorry to hear that you're having an issue with your Nest Thermostat. I'd love to know more about this. Could you share a photo of your previous thermostat's wiring? 

Thanks,

Edward

I am sorry that presently do not have a picture. However, there are only two (2) wires that are connected to a Carrier T3017US thermostat.

Hi JRB-FSU,

Thanks for the response. Could you tell us the labels of the terminals where those 2 wires are connected to?

Thanks,

Edward
