Outlet temperature fault
E29 Return gas temp. Error
E46 DC Fan Error
E20 fault will display the following error codes at the same time, the error codes will switch every 3 seconds. Among
them, error codes 1-128 are displayed in priority.
When error codes 1-128 don't appear, then error codes 257-384 can show.
If two or more error codes appear at the same time, then display error codes accumulation.
For example, 16 and 32 occur at the same time, display 48.
Error name
Code

description
1. The IPM overloaded or
overheated
2. The U,V,W
short-circuited
3. The IPM module fault
4. The compressor damaged
1. Refill the refrigerant
2. Replace the filter
3. Add refrigerant oil to the
compressor
4. Replace the exhaust probe
and reconnect the water inlet
temperature probe
Check and replace the water

Check and replace the suction
gas sensor(T5)
1. Replace the DC fan
2. Reconnect cables to the DC
fan
Solution suggestion
1 Ensure
temperature,
driver temperature, water flow, etc. are
within the operating range of
the unit;
2. Use a multimeter to measure
