E0
Malfunction Description Corrective action
Maybe the connection between sensor and PCB has
Error of sensor T5U(upper water temperature sensor) released or sensor has been broken.
Contact a qualified person to service the unit.
Maybe the connection between sensor and PCB has
released or sensor has been broken.
E1
E2
E4
Error of sensor T5L(lower water temperature sensor)
Tank and Wired Controller communication error
Evaporator temperature sensor T3 error
Contact a qualified person to service the unit.
Maybe the connection between controller and PCB has
released or PCB has been broken.
Maybe the connection between sensor and PCB has
released or sensor has been broken.
Contact a qualified person to service the unit.
Maybe the connection between sensor and PCB has
released or sensor has been broken.
E5
E6
Ambient temperature sensor T4 error
Contact a qualified person to service the unit.
Maybe the connection between sensor and PCB has
released or sensor has been broken.
Contact a qualified person to service the unit.
Compressor discharge temperature sensor TP error
Electric leakage error
Maybe some wires have been broken or bad wire
connection.
Contact a qualified person to service the unit.
If PCB current_induction_circuit check the current
difference between L,N >14mA, system consider it as
"electric leakage error"
E8
Maybe the connection between sensor and PCB has
released or sensor has been broken.
E9
EE
Compressor suction temperature sensor TH error
Contact a qualified person to service the unit.
E-heater open-circuit error( IEH(Current difference
E-heater on & e-heater off )<1A) Maybe the E-heater has been broken or bad wire
connection after repair.
Maybe the chip has been broken, but unit can work well
without clock-menmory, so it is needed to reset clock
when power put on again.
EF Clock chip error
If necessary, contact a qualified person to service the
unit.
Ed
P2
E-EPROM chip error Contact a qualified person to service the unit.
Maybe because of system blocked, air or water or less
refrigerant(leakage) in system( after repair), water
temperature sensor malfunction, ect.

Contact a qualified person to service the unit.
Compressor abnormally stopped protection
The discharge temperature is not so higher than
evaporator temperature after compressor running a
term.
Compressor overloaded protection (10 secs after
compressor startup, current checking starts ,
1)only compressor running, if it is >7A , the
compressor will be stopped and protected.)
2)ComE-heater running, if it is >IEH+7,the
compressor will be stopped and protected.)
Maybe because of compressor broken or bad connection
between PCB and compressor.
P3
P4
Contact a qualified person to service the unit.
Maybe because of compressor broken, system blocked,
air or water or more refrigerant in system(after repair),
water temperature sensor malfunction, ect.
Contact a qualified person to service the unit.
When the ambient temp T4 is out of Heat Pump
running range (-7

43
ć
) Heat Pump will stop, unit will
show LA on the position of clock on display until T4
back to (-7
̚
43
ć
).
LA
It is normal, and no necessary to repair.
Only valid for the unit without E-heater.
Unit with E-heater will never show "LA".
NOTE
The diagnostic codes listed above are the most common. If a diagnostic code not listed above is displayed,
contact residential technical assistance referencing the number on the front of this manual.
If any of P3/P4/P2 continuously appear 3 times within single heating cycle, the third failure code do not
disappear, system will consider it as heat pump system error. Contact a qualified person to service the unit.
