Alde 3030 Control Panel

k11ngy

Not sure if a coincidence but since we had Trailer Electrics repaired behind motorhome, the Alde control panel wont come to life
Changed fuse in Boiler
Did a hard reset
Changed fuse in PSU unit with 4 different fuses
The main panel is on to control heating but without the Alde control panel alive, I cant operate anything

Ideas please

Thanks
Steve
