Daikin RXS50K2V1B
Hi I'm reading 240v on the comms (3) ???
I just replaced both the outdoor PCB. Was told to do this but didn't originally diagnose the fault. Tried to run, straight away the system has gone back in fault. U4. And took out the PCBs again. Indoor did start for a few seconds but then thats when it faulted. Still waiting for daikin to ring me back, but just wondering if anyone has an idea of what's going on. Thanks
