Contact a qualified person to service the unit.

E5

Ambient temperature sensor T4 error

The connection between sensor and PCB is broken or the
sensor has experienced an issue.
Contact a qualified person to service the unit.

E6

Compressor discharge temperature sensor TP error

The connection between sensor and PCB is broken or the
sensor has experienced an issue.
Contact a qualified person to service the unit.

E8

Electric leakage error
If PCB current_induction_circuit check the current
difference between L,N >14mA, system consider it as
“electric leakage error”

The connection between some wires have broken or there is
a wiring connection issue.
Contact a qualified person to service the unit.

E9

Compressor suction temperature sensor TH error

The connection between sensor and PCB is broken or the
sensor has experienced an issue.
Contact a qualified person to service the unit.

P8

E-heater open-circuit protection (IEH(Current difference
E-heater on & e-heater off )<1A)

The E-heater has been broken or there is a wiring connection
issue. Contact a qualified person to service the unit.

P2

High discharge temperature protection
Tp>115°C, Protection active
Tp<90°C, Protection inactive

System is potentially blocked, air or water or low refrigerant
(leakage) in system or water temp sensor malfunction.
Contact a qualified person to service the unit.

P4

Compressor overloaded protection (10 seconds after
compressor start up), Current checking starts,

1.

Only when compressor is running, if it is >7A , the
compressor will stop for protection.

2.

Comp e-heater open, if it is >IEH+7,the
compressor will stop for protection.

Compressor broken, system blocked, air or water or too
much refrigerant in system or water temperature sensor
malfunction.
Contact a qualified person to service the unit.

LA

When the ambient temp T4 is out of Heat Pump running
range (5 ~ 43°) Heat Pump will stop, unit will show LA on
the position of clock on display until T4 back to (5 ~ 43°)

It is normal, and repair is not necessary.

NOTE
The diagnostic codes listed above are the most common. If a diagnostic code not listed above is displayed, please contact for
