Guys, I have removed my ducted dometic A/C unit and installed a non-ducted dometic penguin II with an ADB (air distribution box) with manual controls. The new unit works great and really cools the living room and kitchen better than the ducted unit. The rear unit is still ducted. I did this myself and mainly because I didn't want to replace the thermostat and run wiring back to it. Any hew a/c unit would not work with the old analog thermostat. My problem is once I took the ducted a/c unit out of the wiring loop my furnace doesn't work. I know there were two wires from the a/c control box to the furnace. Well, of course, not now. I know there must be some way I can fool the thermostat to make the furnace work without the a/c but no one has been able to help. I am thinking I could put in a suburban heat only 2 wire thermostat if I could get 12V to it and make it work.
