with boards containing version 2.x of the software. Please refer to the table below for compatibility.

The user interface (UI) board and the input/output (I/O) board must have same software version for correct operation. If
the UI board and the IO board do not have the same software versions an error will be displayed on the UI. The error dis-
played will depend upon which board has 2.x software and has 3.x.Either "X BRL TEMP OUT" will be displayed or "H20
OUT" will be displayed followed 30 seconds later with "X BRL TEMP OUT". If either of these messages is displayed after
changing a control board check the software version. The current software version for each board can be found through the
menu screen. Select, MENU, UNIT DATA, then press the "VER" key. The control boards will also have a label marked with the
part number. A -100 suffix has been added to the part numbers for each of these boards to indicate version 3.0 software
release.
