Eddy 1406 elec choke operation-Not "getting it"

1970 Plymouth Valiant 318, mild cam
So I'm ditching my Holley for this eddy 600 cfm model 1406.
I'm looking at it here on my desk, and I'm not fully understanding the fundamental operation of this electric choke.
It's my understanding that before starting a cold engine, you depress the accelerator pedal all the way, and this activates the choke and high idle.
Is this the same procedure for a carb with an electric choke?
I understand that on a cold engine, the choke plate is closed, and will open slowly as the heated wire expands. But what sets the High idle?
I'm sitting here moving the throttle to WOT but I don't see any high idle being set.
I think I'm missing something and need one of you to set me straight.
thanks
