I purchased a replacement control box for my duo therm ac and the part they sent me was 3313189.000. It came with a digital thermostat but the new thermostat has only 3 wires and the old thermostat had 6 wires. There was no wiring diagram in the box. I need to know how to wire the new thermostat.
You need to get a different thermostat.you can change an analog thermostat to digital, but you have to replace the motherboard with a digital compliant one. You can't just change the thermostat. Your best bet is to put back the old thermostat or upgrade to a different compatable thermostat

my ac works from about 8am til 10pm...after that the breaker trips and I can reset it but it will not stay on for more than 5 or 10 minutes...it doesn't matter if it's off until 3pm and I turn it on it still only works until about 10pm...if it is raining outside then it will trip several times during the day...at night we turn everything off...nothing is running except the ac and a fan...the fan runs all day also...

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.
