OTIS ( Graphics Panel ) is not communicating with the Unit controller. Your going to have to contact your local McQuay Service office. It could be as simple as a lose connection or could
possibly the software code in the controllers ( this all depends on the version of the graphics panel ( OTIS ). If its about 4 " thick its the older version. If its very thin its the newest version.

Note this will not stop the unit from running the OTIS is only for the operator.
