Cooling freezing protection (the
indoor coil temperature is too
low) or heating overload (indoor
coil temperature is too high)
1. The indoor unit can not blow
air normally;
2. The room temperature is
too low in cooling mode or the
room temperature is too high in
heating;
3. The filter is dirty;
4. The duct resistance is too
high to resulting in low air flow;
5. The setting fan speed is too
low;
6. The indoor unit is not
installed in accordance with
