Malfunctions
Observation
Reasons
Solutions
Heat pump is
not running
LED wire controller
shows
no display
No power supply
Check whether cable and circuit
breaker are connected
LED wire controller
displays the actual time
Heat pump under standby
status
Startup heat pump to run.
LED wire controller
displays the actual
water temperature
1. Water temperature is
reaching set value, heat
pump under constant
temperature status
2. Heat pump just starts to
run
3. Under defrosting
1. Verify water temperature setting
2. Startup heat pump after a few
minutes
3. LED wire controller should display
"Defrosting"
Water
temperature is
cooling when
heat pump runs
under heating
mode
LED wire controller
displays actual water
temperature and no error
code displays
1. Chose the wrong mode
2. Figures show defects
3. Controller defect
1. Adjust the mode
2. Replace the defect LED wire
controller, and then check the status
after changing the running mode,
verifying the water inlet and outlet
temperature
3. Replace or repair the heat pump
Short running
LED displays actual water
temperature, no error
code displays
1. Fan NOT running
2. Not enough air
ventilation
3.Not enough refrigerant
1. Check the cable connections
between the motor and fan, if
necessary, they should be replaced
2. Check the location of the heat
pump, and eliminate all obstacles to
assure a good air ventilation
3 Replace or repair the heat pump
water stains
Water stains on heat
pump unit
1. Concreting
2. Water leakage
1. No action
2. Check the titanium heat exchanger
carefully if it shows any defects
Too much ice
on evaporator
Too much ice on
evaporator
1. Check the location of heat pump,
and eliminate all obstacles to assure
a good air ventilation
2. Replace or repair the heat pump
