    Daikin vrv IV start up procedure



    Hiya guys

    During the start up procedure on a RYYQ10T7YB we keep getting the problem of it skipping t08

    We have tried it 5 times now with the same outcome

    What then happens is on the controller it displays the code u3 - 02 (leak detection or refrigeration amount check not performed )

    The system can still run in all its modes with decent heat & cool temps

    But I need to know how to get rid of the code for handover or we will no doubt get a call back .

    Can I manually enter the additional gas charge we added some how ? So the condensir can store the information and then can use it for the leak detection function ?

    If anyone can help would be very grateful

    Thanks a lot
