[C320-list] Xantrex DC Controller - functions?

Hi all,
I have a Xantrex "C-Series Multifunction DC Controller" in the aft starboard locker.  I've recently installed a separate starter battery and had the 2 x 230 AH batteries paralleled, so we turn the battery selector to No. 1 to use the starter battery and then turn to No. 2 to run the house.  Plus we have a VSR installed to isolate the started battery to ensure we should always have power there.
Since the addition of the extra starter battery, the Xantrex DC Controller seems to think the batteries (it is connected to the house bank) are in need of charging, despite several hours of motoring on our recent trip.  I have tested the batteries and all are currently showing about 13.1 volts so I'm not sure why the Xantrex thinks otherwise.  The Xantrex is showing 1 green blink which indicates the batteries are well below what they should be (it blinks between 1-5 times depending on charge levels and then ultimately is on full green when the batteries are fully charged.
I understand there's a reset button on the Xantrex that is probably worth pushing so it can refresh since the house bank is now double the capacity it was previously, but I'd appreciate any help from the group to clarify what functions this unit performs...such as:

  1.  We have 2 x solar panels - I presume the Xantrex plays a role in bringing that charge into the batteries?
  2.  When we are motoring does the Xantrex regulate the charge going into the batteries?
  3.  We also have a Xantrex (Link Lite I think?) battery monitor in the saloon which reads the (correct!) charge for both the starter and house batteries, and shows the net charge coming into, or being drawn from, the batteries....is this connected to the DC Controller at all or just a source of info re charge status?

Thanks in advance for any feedback.
