What does the failure code R22 of Jinjiang air energy water heater mean?

R22 is a refrigerant and belongs to the Freon family. Fault code: R22

Fault content: coil temperature probe fault.

Cause and elimination of failure:

1. First check whether the terminal plug-in of the temperature sensor is loose or has poor contact, and make sure the connection is correct.

2. Check whether the temperature sensor is damaged or faulty and needs to be replaced.

3. Check whether the control circuit board is faulty and needs to be replaced.

Matters needing attention in the use of air energy hot water:

1. Since the air energy water heater absorbs heat through the "outdoor unit", the "outdoor unit" must be installed in a ventilated place, and no sundries should be piled up around it, so that the air energy water heater can absorb heat better.

2, although from the working principle, the air energy water heater will not leak electricity. But the water leakage is not necessarily a problem of the water heater, but also a problem of the power supply. Therefore, when using the air energy water heater, users must regularly check whether the wiring connecting the ground wire, power supply and electrical system is loose, firm, damaged and abnormal.

If problems are found, they should be repaired and replaced in time. In addition, remember to keep the socket and power supply dry, and do not touch water to prevent leakage accidents.

3. Regularly check whether the water pump and waterway valves of the air energy water heater are working normally, whether the valves are tightened, whether the water pipes and water pipe joints are leaking, and whether the water pipes are broken. If problems are found, pay attention to replace them in time.

4. In order to facilitate the operation of users, the new generation of air energy water heaters have intelligent control panels. However, the safety protection devices in the machine are all set before leaving the factory, so users should not disassemble or adjust them themselves, so as not to affect the after-sales service.

5, in order to prevent burns, when using the air energy water heater to take a bath, it is best to open the cold water valve first, then open the hot water valve. The water in the water tank should be replaced in time, which is easy to deteriorate and lead to skin infection after a long time. If possible, it is best to clean the water tank once every six months. Please contact the manufacturer for specific methods of cleaning the water tank.
