Testing operations
AE080BXYD**, AE120BXYD**, AE140BXYD**
1 Check the power supply between the outdoor unit and the auxiliary circuit breaker.
– 1 phase power supply : L, N
– 3 phases power supply : R,S,T,N
2 Check the control panel
– Check that you have connected the power and communication cables correctly. (If the power cable and
communication cables one mixed up or connected incorrectly, the PCB will be damaged.)
– Check the temp. sensor, drain pump/hose, and display are connected correctly.
3 Press K1 or K2 on the outdoor unit PCB to run the test mode and stop.
