What is the otis controller called that was before the 211 ?

That would be the LRV. Was in production from the mid 80s to late 90s and had a number of revisions.

So if I'm looking for prints do I need the year or are they all kind of similar

Otis was good about labeling their equipment.

If you can't find them through your own Chanel's. Call Ramone at Unitec (Otis).

Unitec charges $80 per page for those prints, so be ready.

Yeah I doubt unitech will even be considered as an option with those prices

All I need is the diagram #
