Content
E0
Error of sensor T5U (Upper water temperature sensor).
E1
Error of sensor T5L. (Lower water temperature sensor).
E2
Tank and wired controller communication error.
E4
Evaporator temperature sensor T3 error.
E5

EF
Clock chip charging or clock chip error.
Ed
E-EPROM chip error.
P2
High discharge temperature protection.
P3
Compressor abnormally stopped protection.
P4
Compressor overloaded protection.
LA
Heat pump not in the operation range
E0, E1
Notes:
T5U is the upper water temperature sensor.
T5L is the lower water temperature sensor.
