I have a Honeywell WiFi enabled Thermostat. All cables seems compatible but the red who connects the fresh air Intake. Talked to the installers and they say they don't install Nest nor they know if is compatible at all through the (*) symbol. Basically is a Red cable coming back with power to Furnace (this is what they told me).
Thank you so much for confirming that for me. Taking a look at the details provided, I don't have much information on the U wire on my end. I would recommend having a HVAC pro come out, and take a closer look. They would be able to ensure everything is set up properly.
