Just one A/C here?
Do you have the instructions as per the attached link? http://www2.dometic.com/3e4dfd53-84bb-4915-9038-a303f2dfff4c.fodoc
If you are using old model wiring, I need to know what you had before as far as model of A/C or HP and thermostat.
Just checking back in to see if missed my earlier responses to your question or did you were you able to get this issue resolved?
