I don't think you can program it though the Controller. You need to do it through Apex Fusion. On the Outlet the pump is plugged into, you need to change it to advanced control type and then use code similar to:
Fallback OFF
Set OFF
If SW1 CLOSED Then ON

I hate how R2R is so commercialized and sponsor-oriented (the flashing ads/banners are tiresome), but I still spend time there. These days, however, I find myself spending more time over at Humblefish. I haven't been on RC for years.
I really like my DD jumpguard, but I never used the RedSea so cannot compare. I don't have any cutouts and am using it on a IM Nuvo 20. I like how the tabs are on the corners and it sits slightly recessed into the tank which I find more sleek than the RedSea.
Is Paul no longer the owner? It seems like it is now Jared Bawa. Their newsletters used to have Paul's name at the bottom, but that stopped back in June, and now it has Jared's name at the bottom. Also haven't seen Paul on any of their facebook posts/videos for a while.
