Nest Thermostat Type

[JoeW1]

Is the Nest Thermostat model GA01334-US a Nest Thermostat E or a Nest Thermostat 2020 ? I am trying to determine if my 2 wire heating thermostat is compatible with the Nest I am buying but the description of the thermostat does not say whether it is a Nest E or a Nest 2020

Product code GA01334-US is for the Nest Thermostat (2020) not the newer Nest Learning Thermostat (4th gen).
