I haven't hooked my new, used tub up yet but I'm going over it with a fine toothed comb. It was previously hooked up to a 60amp installation but the factory setting for JP9-7 appears to be in place with the jumper in what I think is the off position. But my question has to do with what exactly constitutes a jumper being off. You see, two of the jumpers are off-set (one obviously so, the other, the fifth from the bottom, not so obvious but it is) so they are resting on only one pin. It seems this would be the same as not having the jumpers on at all, so I interpret this to mean that the setting is off.
Also, to turn on JP19-11 (see chart below) in order to have 2-speed pump logic instead of only 1, it seems all I have to do is get my hands on a spare jumper and place it over both pins to turn this feature on. Correct?
