    Dear Sir,I already wrote to you earlier with a request for help with a problem,but since my computer stopped working in the meantime,I don't know if you have replied,so I am writhing to you again with the hope of your professional help.
    Namely,on the advice of the daikin center Serbia,I bought an RXYSQ5T8VB,they told me that it replaces the old model RMXS140E8V1B,which is connected to two FTXS42G2V1B and one FFQ35B8V1B and through the BPMKS967B3B branch provider unit.When I connected the new outdoor unit I got a UA error.I am checking in the catalog for 2017 it says that the outdoor unit which I buy can work with the mentioned indoor units through the mentioned branch provider.I am totally confused,please help me if you can.Why do I have an error that says that the outdoor and indoor units are not compatible,and what is the smartest thing to do now?Should I buy another outdoor unit or is there another solutions?
    Best Regards
    Dragan Dejanovic

    My unit had U4 and the main PCB lights were off. It ended up being the external unit bottom fan motor causing a short on the board. Replaced the fan motor
