Help Needed Daikin VRV
Hello All,
I have got to look tommorow at a Daikin VRV. I have never even seen one before let alone worked on it. I am trying to get forwarned before i get there, this is a list of all that another engineer has found and i hope someone can give me a clue what to look for.
Fuse V1 (10amp) on top right of PCB blown
No lights on at all on PBC
U4 fault showing on controller.
Apparently there is a smaller board above the main PCB with a two wire link cable going between them. This cable had been pulled off the smaller board so assume it shouldn't effect the running as i dont think the unit has been looked at previously for some time.
Many thanks
Raymond
