I'll try to remember to look at mine today. I think my nest is only setup with four wires and I do have the ability to control the fan alone. I have it set to run a little every hour during the day when we are not home and the system is set to "away temps".


Nest E is what I was looking into. It's an older model on clearance at Sam's for $80.
