Guides & Information

Before You Buy
The A-282 Control Board is part of a legacy DX & TW cabin control system sold from the late 1990s through the present. It was discontinued by the Original Equipment Manufacturer and is available only from Micro-Air, which made it for the Marine OEM and improved it for your replacement purchase today. It was also sold into a specialty Class A Coach/RV application where the Cruisair manufactured air conditioner was installed in the “basement” of large RVs.

The original board featured five 6-pin jacks and a plug in DIP style ROM chip with markings that identify the application by the color of the label used on the board. The Cruisair boards had a number (42,600) printed on the board. All of the connections from the board to components were made along one side of the board using spade style connections. Boards measured 7” x 6.4” [17.8cm x 16.3cm].

These boards come in three configurations. Yellow labeled boards directly drive a compressor in direct expansion marine applications. Blue labeled boards are used in an air handler for chilled water marine applications. Red labeled boards are used for Class A RV coach applications. Select the correct application from the pull down box before ordering.

It also relaces Dometic part number 701500101. Those control boards were used on SMX-net systems and Cruisair RN, FN, SN, and SNR units.
