Outdoor machine fault code
The machine units are not locked and no fault, in turn cycle "in the machine number, machine
capacity, power supply type".
(1) The connection machine number: display "H" + machine units.
0
Such as "H08" means that the machine is connected to the 8 internal machine .
(2) Outdoor mechanism cold capacity: such as AU05 machine display 6HP.
(3) Power supply type: 220 represents a single phase 220V, and the 380 represents a three-phase
380V).
