E12 High exhaust temp. protecon
1. Replace the compressor exhaust temperature sensor.
2. Reconnect or clean compressor exhaust temperature
sensor and wrap it with insulaon tape.
3. Replace the controller or PC Board.
E15 Water inlet temperature fault Check the connecon, change the sensor if necessary.
E16 External coil temperature fault Check the connecon, change the sensor if necessary.
E18 Exhaust temperature fault Check the connecon, change the sensor if necessary.
E19 DC fan motor fault
Check DC fan motor. Change it if damaged. Check output
port of DC fan motor on PCB. Change the PCB if there is
no output.
E20
Abnormal protecon of frequency
conversion module
Solve it according to the subsidiary error codes in the
following table.
E21 Ambient temperature fault Check the connecon, change the sensor if necessary.
E23
Low outlet water temp protecon
when cooling
Check the water ow and water system, mend it if
necessary.
E27 Water outlet temperature fault Check the connecon, change the sensor if necessary.
E28 CT over current protecon
E29 Sucon temperature fault Check the connecon, change the sensor if necessary.
E32
High outlet water temperature
protecon when heang
Check the water ow and water system,mend it if
necessary
E33
Outdoor coil high temperature
protecon
Wait for the ambient temperature drops and restart the
unit.
E42 Internal coil temperature fault
The E20 fault displays specic error codes, detailed in the following table.
Error codes 1 to 128 are displayed in priority. Error codes 257 to 384 are only displayed if the
previous ones do not appear.
