water temperature)
When the water tank or ambient temperature sensor are faulty, electric heating operation is not allowed.
“11E”, “12E”, “13E” ", "14E", "15E", "17E", "18E", "19E". are correspondingly displayed when the coil
temperature sensor, ambient temperature sensor, exhaust temperature sensor, inlet water temperature
sensor/tank temperature sensor, absorb temperature sensor, and outlet water temperature sensor/return
water temperature sensor are faulty.
4.10 Other:
“09E” is displayed when the communication between the main control board and the wire controller is
abnormal or the data line is not connected normally. “--:--” is displayed when the valid clock cannot be
obtained. And the communication indicator of the main control board flashes. The buzzer sounds when an
alarm occurs. Press any key to silence the alarm.
The fault code table is as follows:
Error code
name
01E
water flow switch disconnected(water cycle heat pump)
02E
exhaust temperature too high
03E
high-pressure switch failure
04E
low-pressure switch failure
09E
communication failure
11E
evaporator coil temperature sensor failure
12E
ambient temperature sensor failure
13E
exhaust temperature sensor failure
14E
water inlet temperature sensor failure
15E
tank temperature sensor failure
16E
17E
absorb temperature sensor failure
18E
water outlet temperature sensor failure
19E
return water temperature sensor failure
20E
outlet water temperature too high protection(water cycle heat pump)
21E
outlet water temperature too low protection(water cycle heat pump)
9. Adjusting and Initial operation
9.1 Attention
●Within 12 hours after running, please connect the circuit breaker, and make the crankcase heater be
pre-heated.
●Open the valve of water system, and the valve of assistant tank, inject water into the system, and
exhaust air inside.
●Do adjustment after electrical safety inspection.
●After the power is switched on, start the test running of heat pump, to see if it can function well.
