Looking for a second opinion to validate my plan to re-wire an old thermostat (carrier) to a Nest Learning thermostat. The thermostat controls a dual-fuel heat pump/gas furnace on the 2nd zone of the house.
Wiring map plan (labeling from old thermostat --> Nest):
Anything strike folks as odd / off here? Thanks!

@gsoltes1 , your wiring looks correct for a heat pump that is a type O. and, the two Sensor wires are not needed and taped off is good.
