Hi, welcome to the community 
The dCS platforms use the Philips RC5 protocol for IR remote control. So, any programmable remote that supports RC5 codes will work.
You can get the full documentation of the RC5 codes for the Paganini at dCS’ documentation site; https://dcsaudio.com/documentation (just select REMOTE CONTROL for the [DOCUMENT TYPE] selector and it’ll take you to the “Remote Control Codes” PDF, on page 2).
