Thought I'd try to clear this up. If your controller is part# fi-6050( 4 adjustable pots) its a GENII. I've seen alot of talk about people having the GENIII, when in fact they probably have the GENII. After talking with the Dobeck tech today, you can't even buy a GENIII from them, nor is it on their website. They only make the GENIII for acouple of companies(Trinity is one, and i forget who else the tech said).
