Actually having read your post with the second diagram where you say how you get it to work with a NO contact I think my previous instructions apply also to a NO configuration. 

There's missing information, the instructions that go with 3.8 appear to describe how to set up for a NO config but there dosen't seem to be any info for NC config.  Is there another diagram after 3.8.

Please, please, please, can you give a model number or access to the full installation manual.  It's pretty hard to help with only a little amount of information.
