16.5.22. 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: 0.65A < I < 1.65A.
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.
