Refrigeration Cycle Abnormality (F24)

Malfunction Decision Conditions:

1  During operation of cooling and heating, compressor frequency > Frated.
2  During operation of cooling and heating, running current: 0.65 A < I < 1.65 A.
3  During operation of cooling, water inlet temperature - indoor refrigerant liquid temperature < 5°C.
4  During operation of heating, indoor refrigerant liquid temperature - water inlet temperature < 5°C.

Malfunction Caused:

1  Faulty water inlet or indoor refrigerant liquid temperature sensors.
2  2/3 way valve closed.
3  Refrigerant shortage (refrigerant leakage).
4  Clogged expansion valve or strainer.
5  Faulty outdoor unit PCB (main).
6  Poor compression of compressor.

Abnormality Judgment:

Continue 2 times in 20 minutes.
