Hi was woundering if anyone can help me with an issue I have with some vrv units.
Have 4 ducted indoor units off 1 BRC1D controler. The controler says unit 4 is AF. I know the fault is about the float switch. But is there a way to figure out which indoor is unit no 4 from the controler? Could save me a lot of pain trying to gain access to units that are not in fault. Thanks
