I don't think Ecobee is not compatible with stage 2 furnace.

You need an separate wire to connect W2, but W2 is not required if you know how to set your furnace to handle it.
You also need a kit from Ecobee if you only have 4 wires.
Thanks for correcting me.

It should be "Heat Differential Temp" - Select Main Menu > Settings > Installation Settings > Thresholds > Heat Differential Temp
and "Cool Differential Temp" - Select Main Menu > Settings > Installation Settings > Thresholds > Cool Differential Time
