Remote controller for chilli net replay panels

[RFLighting]

I'm installing some chilli net replay panels and noticed they have an IR receiver window for a remote controller. 

I can't seem to find any information regarding this. Which if any remote controller is suitable for use with these panels?

If any universal remote is compatible, is there any information available for programming the remote into the panel?

Thanks. Rob.

We did at one point have a IR remote in the range but it was discontinued a number of years ago now.

Not sure about the universal remotes as they are geared towards TV, DVD etc, but if the information i have is correct try RC5 group 30 as the pairing option.
