Dear All,

I have checked out this split unit, it is a ASAA24JCC
A 2.5HP INVERTER WALLMOUNT.

It has been newly installed few months back, but hardly used as the house is being renovated etc.
when the unit is turned on, the unit just blinks 2 times - timer LED

That means serial reverse transfer error, ussualy a problem with the PCBs indoor or outdoor, or supply to the PCBs.

I have checked all, everything seems to be fine.
Checkd the Outdoor fan, expansion valve, PCBs replaced yet the same blinks!

Any idea what could it be ? Do you think the installation not done correctly as in vacuuming and gassing up ?
