Daikin Vrv IV
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

Re: Daikin Vrv IV
Are the only faults the U3 -02?
The error is with fan coil 02. It will not pass the initial TEST run if you have faults, which is what you are seeing.
What do you mean by '2 remote stats'?
Double check your wiring

Re: Daikin Vrv IV
So the test run has not been completed on the error unit.
Did you restart a test run after fitting the remote sensors?Brian - Newton Abbot, Devon, UK
