That 4th 3 pin connector is, from what I understand, for an additional Solar JVA and the one beside it is for a Solar Aux, for something like a Heater.
Which one of those (if any) is for your Smart JVA? Im assuming your smart jva module is the same as mine, just to make sure. I just dont know why nothing is showing for me to set up, its all powered up. I get the littel green blinking light on the smart jva board and my control panel comes up too.
