007,
A Feature Circuit is the same as an Aux Circuit, except the Aux circuit has a relay (which is not needed to move a valve) and a button on the main panel.
If you want/need a button, you will have to use a Aux Circuit.
If you want to just use your remote, then just assign your Feature Circuit to one of the Remote buttons.
Do you have ScreenLogic, and the Pentair remotes, or just the remotes.
What specific remote do you have???
Thanks,
Jim R.
