I have a 2004 Newmar Kountry Star with 2 roof top AC units by Dometic. I am having problems with the rear AC unit not working. I have completed a lot of trouble shooting and found that the telephone style cable from the Comfort Control Thermostat has 1 bad wire in the cable from the front AC board to the rear AC board. This cable is running from P2 to the P2 socket on the 2 control board.
My question is, what is the purpose or were does the cable from P1 on the rear AC control board go to.
P1 on the front AC unit connects to the CC Thermo, P2 on the front unit connects to P2 on the rear unit.
My second question is, the Dip Switches. Front AC control board, all set to OFF except no. 5 FURNACE is set to ON. On the second unit, all are OFF except no. 2, ZONE 2 set to ON. From what I have read, this should be the correct settings.
Thanks for any help.
