Content
E0
Error of sensor T5U.
E1
Error of sensor T5L.
E2
Tank and wired controller communication error.
E4
Evaporator temperature sensor T3 error.
E5
Ambient temperature sensor T4 error.
E6
Compressor discharge temperature sensor TP error.
E8
Electric leakage error
(If the mutual inductor reveal a difference between L and N >14mA)
E9
Compressor suction temperature sensor TH error.
EE
E-heater open-circuit error ( Damaged resistance )
EF
Clock chip error.
Ed
E-EPROM chip error.
P1
System high pressure protection
(>2,76MPa (26,6 atm) ON, < 2,07MPa (20,4 atm) OFF)
P2
High discharge temperature protection
(Tp>115°C ON, Tp<90°C OFF)
P3
No current flowing in compressor.
P4
Compressor overloaded protection.
LA
Ambient temperature is not fit for heat pumps; change the mode to E-heater.
E0, E1
Note:
T5U is the upper water temperature sensor.
T5L is the lower water temperature sensor.
