I don't fool with any of the controls or settings, I set it for 725*F, let it auto tune itself and haven't changed a thing.
When I put mine together, I didn't get all the connections right but, no magic smoke escaped. I had some help to figure it all out and there's plenty of knowledgeable guys that will help out. Just post any problems you encounter, no matter which controller you have. If you go by the schematics and just connect one wire at a time, one by one, "A" to "B", everything should go fine.
