The Ecobee power extender kit uses the power stealing technology meaning that it will try to steal as much energy as it can from the HVAC control lines to recharge its batteries. The thermostat gets more energy when the system is off and gets less when it’s running meaning that the chances of failure are higher if your AC is almost ever running.

How does the ecobee work with the Furnace Fan?
So in the idle state, Y is open and the ecobee power circuit is completed by C to the furnace (via Y at the thermostat). And when the fan needs to be turned on, C is opened, Y is closed, and the ecobee power circuit is completed in series with the fan coil (again via Y at the thermostat). How it communicates this switching action- I have no idea!
