12 Automatic Wiring/Piping Correction Function
Climate 5000 models now feature automatic correction of wiring/piping errors.
Press the "check switch" on the outdoor unit PCB board for 5 seconds until the LED
displays "CE”, indicating that this function is working. Approximately 5-10 minutes
after the switch is pressed, the "CE" disappears, meaning that the wiring/piping
error is corrected and all wiring/piping is properly connected.
