Failure Causes
Power supply phase sequence error
The power supply is out of phase
1. Circulating pump failed, or water
system blocked
2. Water flow switch failed, or
opposite installed direction
3. The lift of the circulating pump is
not enough
4. Circulating pump has opposite
installed direction
Check the communication connection
1. High-voltage switch failed
2. Excessive refrigerant
3. Fan doesn't work typically, or water
circulated abnormally
4. Air or other objects mixed into the
refrigeration system
5. Too much scale in the water heat
exchanger
1. Low-voltage switch fault
2. Lack of refrigerant
3. Fan doesn't work normally
4. Block exists in refrigeration system
