They're going to probably pay for a Lutron system by the time you get this back up to snuff and working over a few years, if that even happens.

Either tell them good luck on finding an HAI UPB specialist, or they have to pay for you to go Hero Mode. Which might cost as much as a brand new Ra2 system.

I'm taking care of a few of these systems now.

Tech support is some guy on the east coast (NC or TN maybe?). I cannot recall his number, you have to call Leviton (HAI) to get it.

Good luck.
