Ecobee 3 Compatability

kenny@allanworld.net[email protected] Davenport, FLMember

They may be good at making smart thermostats but they ain't so good at answering the phone.

I have an opportunity to buy an Ecobee 3 at a good price I just want to know if its compatible (their checker wasn't conclusive)?

My current stat is wired thus:
G = Green
C = Blue
R = Red
W1 = Bridged with Y
Y = Yellow
L = Not connected
W2 = White
E = The conductor of the white wire is connected to W2 but also appears to touch the E terminal
B = Not connected
O = Orange

I have a single fuel (electric), heat pump condenser

    W1 and Y being bridge is odd. That is likely by the comparability checker was confused.
    W2 and E being bridged is normal and everything else look normal.

    What is the make and models of your furnace/air handler and the heat pump?
