without a picture I'm just guessing that you have only the AGS Module, maybe near the generator, with several knobs that you use to tell it 'why' 'when' and 'how long' ... you may not have the capability to do much more, since the other 'settings' are probably built-in and can't be changed. The REMOTE simply let's you do that from within the coach.
