Hi guys,

First commission of a Daikin VRV ,
I have 3 systems , 2 are working fine (3 pipe ) but one is giving me trouble ,

2 x FXSQ 125a ducted units
1 x RXYQ10T7Y1B

The system will run but won’t clear U3-02 fault from test run , I have ran through the auto charge procedure but it still comes up any ideas ?

Only thing to mention is two remote stats have been fitted , system runs fine but fault coming up on controller . I need to be able to hand it over without faults
