OK, what you have is an EP Tracer Solar 3215
RN. For the Etreks, it's a 3215
BN which has an additional format for programming to suit lithium batteries. Since you are using AGMs, the RN version is what you have. You'll notice that it has an RJ45 port that is unoccupied. EP Solar makes a remote meter MT-5 that will provide you a display showing panel voltage and controller output.
Two things:
You can edit the controller program from this meter, but be cautious in doing so. Roadtrek programmed it for supporting AGMs.
The meter you need is an MT-5, not the MT-50 which supports the BN series controllers.
