Other Malfunctions and Solutions (No display on LED wire controller)

Malfunctions

Observation

Reasons

Solution

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

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

protection

320

High compressor

peak current

1.Compressor current is too high.

2.The driver program doesn’t match

with compressor

Replace inverter module

384

PFC module

over-temperature

Temperature of PFC Module is too

high
