broken or sensor has been broken.
Contact a qualified person to service the unit.
8
Some wires have been broken or bad wiring
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"
lectric leakage error
Compressor suction temperature sensor TH error
9

broken or sensor has been broken.
Contact a qualified person to service the unit.
-heater open-circuit protection (I H(Current difference
-heater on & e-heater off )
Maybe the -heater has been broken or bad wiring
connection after repair.
P2
High discharge temperature protection
Tp>115℃, Protection active
Tp
System blocked, air or water or low
refrigerant(leakage) in system (after repair), water
temperature sensor malfunction, etc.
Contact a qualified person to service the unit.
Compressor overloaded protection (10 secs after
compressor start up), Current checking starts ,
1)only compressor running, if it is >7A , the
compressor will be stopped and protected.
2)Compressor+e-heater opend, if it is >I H+7,the
compressor will be stopped and protected.
Compressor broken, system blocked,
air or water or too much refrigerant in system (after
repair), water temperature sensor malfunction, etc.
℃
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 not necessary to repair.
