Remote Fadini Astro 43/2 TR with 2 channels. Also known as the Astro 43-2TR small or mini.
NOTE: The Remote Astro 43-2 TR has a fixed code that works with DIP-switches on the inside of the remote. There also exists the Fadini Astro Jubi 433 that looks just like it, aside from the shape of the LED light. This remote works with a rolling code and is not compatible.
Synchronize the DIP-switches in your new remote with the old remote. Don't have an old remote? Consult the settings in your receiver.
