I recently got some of the Nest Thermostats for Christmas. According to the compatibility checker, I might need a Nest Learning Thermostat for my system. Can anyone confirm if I should return the Nest Thermostat and get the Learning? Pictures are below. We're in Georgia, the system is a heat pump with electric furnace.
The other side of the house is a different system, but has a furnace as well. There was a jumper between W2 and E, and the brown wire wasn't used. I connected a Nest Thermostat here, and I think it is working as expected (picture attached).
