I m working on my new air conditioner and i am trying to match the analog thermostat to the control enter. too many wires

Had one doing similar recently, and after a thunder & lightning storm. Nothing worked, but kept blowing 2 amp fuse in thermostat, when anything tried, heat or cool. Pulled plastic control box down from inside upper unit (AC) made sure breaker was off, took of plastic cover and smelled inside, and could smell burnt plastic smell. Replaced, control box, that got fan only working. Tried another thermostat , everything worked as it should. Turns out the lightning, or power surge, or whatever, shorted out the thermostat, and control box at same time.

You know what, I have never ran into that yet in 15 years, so I think your best bet would be to go to, (dometicusa.com) and send then a quick inquiry to confirm, what would be required, they are usually pretty helpful believe it or not.

use relays to combine the to and isolate from each other or observing polarity's, you should be able to parallel the connections from your thermostat
SOURCE: need to install a dometic
A schematic of the part number can be found here... Duo Thermostat Wiring.pdf
Additionally, go HERE for the Dometic Service Manual. See pages 39 and 40 as well as 50 and 51. Depending on which unit you have this gives the colors coding for the leads as well as the placement on the thermostat.
Hope this helps; keep us updated.
