Carel Smart Key Dongle PLC Board Programmer

Carel Smart Key dongle used for programming PLC boards found in many Dometic and Condaria AC and ventilation products.

Smart Key is used to add software to an unprogrammed PLC board or to update an existing PLC board. Software is NOT included with this dongle. Used to update 20-2000 and 20-2001 Carel PLC boards.

Below are ways you can obtain the software.

1. If your vessel has more than one AC system, download the software from a working AC unit to the dongle, then upload that software to the new board. Dometic units use all the same software and each stage must have the exact same version for proper networking. For Condaria units, each stage has its own software version. Disconnect all network wires between the stages prior to updating the boards. Power each unit off before connecting the dongle. Ask us for instructions.

2. Obtain the software from the manufacturer of the AC equipment. Keep in mind that the manufacturer may require you to buy their board or Soft Key already preprogrammed at a much higher price.

The Soft Key dongle will only hold one version of software. Multiple versions of the software can be saved to your computer but will require downloading software from Carel and purchasing a 70-7001 Carel USB key adapter. Connecting the Smart Key directly to your computer may cause damage.
