Resolved Question:

i have a dometic/duo therm/penguin II, model #610012.103. the touchpad thermostat control had to replaced with the(NNN) NNN-NNNN028 upgrade kit and the wall mounted comfort control center, part #3109228.001.
i removed the original module board and replaced it with the upgrade. upon completion, there were 2 yellow (power shed) and 2 blue (furnace) cords left from plug p6 unconnected with no reference in the installation instructions, (rev.(NNN) NNN-NNNN013), as to their disposition. i have only one unit in my rv and, after contacting Dometic tech services, was advised to "just cap them off". having completed the above, i continued to install the CCC.
i, originally, plugged the rj11 connector into the p1 port on the module board and followed the instructions for routing of the control cable connection. i hooked up power, did the required CCC reset and all i got was a display on the LED readout.
thinking that a connection may have come loose, i checked (ok) and repositioned the control cable into the p2 port. now there is nothing.
is there a pdf schematic that can be downloaded to ensure that the "polarity" is correct between the module board and CCC? or do i need to flip any dip switches to the on position when i changed the rj11 from port to port. the upgrade instructions state that the only dip switch that should be turned on is if there is an electric heat strip.
