ERROR CODES

SHOWN ON ERROR
CODE
E0
Wired
controller
E1
First level
When the unit is on standby and ambient temperature≤5 °C,
water pump starts, the wired controller shows code "P1"�
When the unit is on standby and ambient temperature >5 °C,
water pump stops, the code "P1" disappears�
Second level
When the unit is on standby and ambient temperature ≤5 °C
and water outlet temperature <3 °C, the unit starts heating, the
wired controller shows code "P2"�
When the unit is on standby and ambient temperature >2 °C or
water outlet temperature >8 °C, the unit stops heating, the code
"P2" disappears�
This protection is only valid when the water temperature is
control object�
CAUSE
1� Wire connection
between wired controller
and PCB open or short-
circuited�
2� Wired controller
failured
1� Indoor room temp�
sensor in the wired
controller open or short-
circuited�
2� INdoor room temp�
sensor resistance drifting�
3� Temperature sensors
not well connected to the
wired controller�
CHECK AND CORRECT
1� Check whether the wire connection gets loose� Fasten it�
2� Change it�
1� Measure with a multimeter at 20K to check whether it
is short-circuited or open� If yes, change it��
2� Measure with a multimeter at 50K to check the sensor
resistance� Take ambient temp� into
consideration� If it is drifting, change it�
3� Check whether the sensor connection gets loose�
Fasten it�
