Wow! more than I ever realized about climate controls and the different models. My 1984 380SE takes 126 830 0285 (60285)
(ProgRama's number?)model.

The CCU's I have are this model.....at least the cover panels are the same MB number. Now I know for sure that I have at least two different configurations, two with a mother board,a child board and two wing boards (each have 6 relays) One has only the one motherboard and two wing boards. (5 relays). This one appears older than the other two.

I will doing the ProgRama tests this weekend. Then I should know where I stand.

I may send my original (best shape) CCU to them for a rebuild. Only two traces are burned through on this one. and from the diagrams it was the AWP that fried it. I'm going for a NEW AWP and I'll rebuild my Monovalve also. My AWP is dead as is the one I bought to replace it. GRRR! Monovalve does work when the CCU is working. It now is in the open mode(defrost).

Someone provided parts of the Climate control manual on this site or another and I downloaded that part. it was not complete, but it did have all the diagrams.

Thanks for the help John. I feel much, much better now.
