Question: what is the difference between google nest learning thermostat and thermostat e?
Answer: Functionally, the Nest Thermostat E has almost all the same options as the Nest Learning Thermostat. The most significant differences: The E only works with 85 percent of 24V heating and cooling systems (it lacks the additional wire terminals of the Nest Learning Thermostat), and it lacks Nest's Farsight feature.
