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.
