Volume problem 220 Pro

[Marietto]

Hello everybody ,
I have a serious problem with the volume of my 220 Pro.
it happened twice that the volume went to the maximum with serious risk to my speakers.
Both from remote and from Roon it was not possible to turn down the volume, it returned to maximum levels.
Yesterday the amplifier (protection?) Was switched off by itself, switched on again and played regularly.
Has it ever happened to anyone?
how to solve?

thank you

Change the batteries in the remote.
It happened to me once. A couple of minutes before it, I realized that the volume on display "played" with +  - 0.5 value.
I was intrigued about that since I didn't touch the remote and after a couple of minutes, my Dev went on maximum load. 
Protection was activated and switched off. Then I changed the batteries and everything was fine. No any damage on speakers or Devialet. 
It happened 3 years ago.
Since that, without any problem. 
regards

thank you
for now I'm only using the remote from Roon, I have to recover from the shock  

Regards
