Changes For Marine Air

  • The new U board began shipping from the factory in early July 2015 starting with serial number 528xxxxx for Turbos, Emeralds, and chilled water systems.
  • The U board is a mechanical drop-in replacement (same footprint), however the wiring and terminal-block layout do change. Order part number 223100502, which consists of the replacement U board for DX systems, generic wiring diagram, and terminal strip label. The U board is compatible with these Marine Air displays and firmware versions:
    • Elite – Firmware releases A 13 and later.
    • Passport VO – Firmware releases A 12 and later.

How To  Identify Systems With The U  Board

An easy identifier for the new board is in the  unit model description:  The letter “U” after the BTU number means the  unit contains the new control  board.   For example:  STQ16U = 16,000 BTUs with  new U control board.

New Terminal  Locations

The terminals and their locations vary from the previous boards. In addition to referencing the attached generic wiring diagrams, you can refer to the following picture which shows the new layout, electrical connections, and terminals. Or, refer to the specific electrical diagram inside the electrical box of the unit.
