Has anyone been thrown U1? The machine counts all bs boxes and fan coils but gives me the code when I try to start auto charge. I can get to check operation and manually charge
Figured it out, when you go to auto charge and get a U1 code you have to power down for 24 hours OR manually charge while running check operation then when that dinishes with no alarms you can run in auto charge. Kinda weird
The U1 error code is incorrect rotation... just change the line volt wires, and reset the indoor units.
I hope he would have figured it out in over a year....
