Check the electrical continu-
-------
Check the electrical continu-
ity of FUSE CF2 with a tester
Check the voltage of the FAN
Check the electrical continu-
10kW Unit: Check the electri-
cal continuity of FUSE CF6
13-16kW Unit: Check the
electrical continuity of FUSE
Check the voltage of the FAN
Check the installation room

Solution
Replace the sensor if it is faulty.
Replace the PCB MAIN
If fuse CF7 is blown, replace the FAN MOTOR
and the fuse. If fuse CF6 is not blown, check the
is normal, replace the FAN MOTOR. If the volt-
age is abnormal, replace the PCB MAIN board.
Replace the sensor if it is faulty.
If fuse CF6 or CF7 is blown, replace the FAN
MOTOR and the fuse. If fuse CF6 or CF7 is not
blown, check the voltage FAN MOTOR and the
fuse. If the voltage is normal, replace the FAN
MOTOR. If the voltage is abnormal, replace the
PCB MAIN board.
Correct the installation position to prevent the air
intake and output pipes from clogging.
Replace the PCB MAIN
Replace the PCB MAIN.
Replace the PCB MAIN.
Once the wiring error is corrected, reactivate the
appliance.
Verify that the earth wire has been installed cor-
rectly.
Replace the PCB TERMINAL BLOCK.
Replace the PCB MAIN.
If the same error code appears again, replace the
PCB MAIN.
Check the connection of the wiring and the incor-
rect contact and then restart the appliance.
Verify that the earth wire has been installed cor-
rectly.
Replace the PCB TERMINAL BLOCK.
Replace the SMART-MT.
