Carel Smart Key Dongle PLC Board Programmer

The Carel Smart Key dongle is designed for programming PLC boards used in many Dometic and Condaria AC and ventilation systems. It enables adding software to unprogrammed PLC boards or updating existing ones. Note that software is not included with the dongle. It supports updates for Carel 20-2000 and 20-2001 PLC boards. Software can be obtained by downloading it from a functioning AC unit on your vessel or directly from the equipment manufacturer. The dongle holds only one software version at a time; managing multiple versions requires additional Carel tools. For guidance or questions, contact us—our experts are ready to assist. Electrical parts are non-refundable; exchanges accepted within 30 days.
