hi frens..
any help for above problem...?
During heating operation (Comp. ON), the highest detected temperature at an outdoor unit
heat exchanger (EXG 1, EXG 2, EXL 1, or EXL 2) was 20°C or more above the outdoor air
temperature (Air Temp.) continuously for 5 minutes or longer, or the detected suction
temperature (SCT) was 20°C or more above the outdoor air temperature continuously for
5 minutes or longer.
Check sensors.

(1) The 4-way valve connector (20S CN022) has become disconnected from the control PCB.
(1) Check the 4-way valve connector (20S CN022).
If the connector is normal, correct or replace the problem locations
summary is a bit vague
Without checker for ECO hard to find that error, but you can see all parametrs from wired controller.
Dear sir,
i will check it as per your advice....
@Rusbuka: which model number of wired remote controller i can see all the parameters?
is it normal one..?
