Will Nest E work for me?

Community Member

Looking at a Nest E but am not sure if it does what I need.

I have a heat pump and electric backup furnace.

Current controller is an AUBE CT280-3H3C currently wires are:

TH - 2 of them

OS - 2 wires into the one connection

R (2 wires) C (2 wires), Y1,Y2,W1,W2, W3/O/B, L, G, W/W

am I correct in understanding-

- OS wires are not needed (nest uses the internet)

- TH are not needed as the nest is a thermostat and controller all in one

- nest E does not have W2 but manual says it can go in the O/B socket? If so, how does it make a call to the heat pump vs the electric furnace?

- what about the WW, C wire(s)

- am I good to persist with 2 wires into R (and wherever C goes)


any ideas?

Basing on your wiring I think it's better if you get a Nest Learning Thermostat 3rd gen. Look for the compatibility widget that help you to get a better answer.
