16.4.20 F17 (Indoor Standby Units Freezing Abnormality)

Malfunction Decision Conditions



When the different between indoor intake air temperature and indoor pipe temperature is above 10°C or indoor

pipe temperature is below -1.0°C.

Remark:

When the indoor standby unit is freezing, the outdoor unit transfers F17 error code to the corresponding indoor
unit and H39 to other indoor unit(s).

Malfunction Caused



Wrong wiring connection



Faulty sensor



Faulty expansion valve

Troubleshooting

YES

When F17 indication happens

Check the system wiring connection

Is the wiring connection ok?

●

Perform Auto Wiring to correct the

●

Replace the indoor intake air or indoor

●

Replace the solenoid coil or expansion

YES

Check the indoor intake air and indoor pipe temperature
sensors

Does it conform to the sensor characteristic chart?

Check the expansion valve

●

Replace outdoor unit PCB

Is the expansion valve ok?

pipe temperature sensor

valve

wiring connection

Caution

For safety reason and to prevent
component breakdown, always switch
off the power before remove and
connect the component.
