sensor
If the indoor sensor is detected of open circuit or short circuit for 5
seconds successively, the indoor room temperature will forcibly set to
24 . In this case, the system will not perform any treatment, only the
℃
indicator will blink or display the fault code. The system can
automatically resume after the failure is eliminated. Under fan mode,
only the fault will be displayed, but the indoor unit will run normally. The
fault disappears after it is eliminated.
F1

Temp. Sensor
Malfunction
Outdoor
evaporator
sensor
If the evaporator sensor is detected of open circuit or short circuit for 5
seconds successively: When under cooling and dry mode, the system
will be stopped. When under heating mode, all of the loads except the
4-way valve will be stopped, while the indicator will blink or display the
fault code F1. After the fault is eliminated, the system can automatically
resume to operation and clear the fault display. Under fan mode, only
the fault will be displayed, and the indoor unit will run normally. The
fault disappears after it is eliminated.
F2
Condenser

Malfunction
Outdoor
condenser
sensor
If the condenser sensor is detected of open circuit or short circuit for 5
seconds successively: When under cooling and dry mode, the system
will be stopped. When under heating mode, all of the loads except the
4-way valve will be stopped, while the indicator will blink or display the
fault code F2. After the fault is eliminated, the system can automatically
resume to operation and clear the fault display. Under fan mode, only
the fault will be displayed, and the indoor unit will run normally. The
fault disappears after it is eliminated.
For cooling-only unit, the other units except the duct type will not detect
the condenser sensor fault.
F3

If the outdoor environment sensor is detected of open circuit or short
circuit for 5 seconds successively: When under cooling and dry mode,
the system will be stopped. When under heating mode, all of the loads
except the 4-way valve will be stopped, while the indicator will blink or
display the fault code F3. After the fault is eliminated, the system can

mode, only the fault will be displayed, and the indoor unit will run
normally. The fault disappears after it is eliminated.
F4
Malfunction of
Exhaust Temp.
Sensor
Exhaust
temperature
sensor
If the outdoor temperature sensor is detected of open circuit for 5
seconds successively after the compressor is started: When under
cooling and dry mode, all the loads will be stopped. When under
heating mode, all of the loads except the 4-way valve will be stopped,
while the indicator will blink or display the fault code F4 and the buzzer
will alarm. After the fault is eliminated, the system can automatically
resume to operation and clear the fault code.
If the outdoor temperature sensor is detected of short circuit: When
under cooling and dry mode, all the loads will be stopped. When under
heating mode, all of the loads except the 4-way valve will be stopped,
while the indicator will blink or display the fault code F4 and the buzzer
will alarm. After the fault is eliminated, the system can automatically
resume to operation and clear the fault code.
F5
Malfunction Of

Controller
Wired controller
If the wired controller is detected of open circuit or short circuit for 5
seconds successively, the indoor room temperature will forcibly set to
24 . In this case, the system will not perform any treatment, only the
℃
indicator will blink or display the fault code. The system can
automatically resume to operation after the failure is eliminated. Under
fan mode, only the fault will be displayed, but the indoor unit will run
