The Nest thermostat will not support the high efficiency Carrier HVAC units. On the Nest website it was listed as compatible so I gave it a shot. Installed OK, but then on first update it blew up the control board on the furnace, which ultimately had to be replaced. I called Nest about this and they looked it up and ultimately verified that the Nest thermostat was not compatible with the Carrier units. The Carrier equivalent, having phone access, is outrageously expensive. Any ideas would be welcomed.
