I did a bit of searching but couldn't find anything relevant
I have an R410a 3pipe VRV (single condensor) the problem was all 10 fan coils were in a UE fault so I shut the system down and reset the condensor so it would search for all fan coils again
It detected all fan coils and I thought I had cracked it, but 30secs later 5 fan coils were working fine the others went into a U9 fault
I am attending site tommorow as time was getting short this evening, could it be a splitter box or fan coil with no power creating this fault?
