Why is my Pioneer YH024GHFI18RT2 Heat Pump showing cooling freezing protection or heating overload?

If your Pioneer Heat Pump is experiencing cooling freezing protection or heating overload, check if the indoor unit is blowing air normally. The room temperature might be too low in cooling mode or too high in heating. Also, clean the filter, check the volume control valve and duct length, and ensure the fan speed is set high. Verify that the indoor unit is installed correctly, maintaining proper distance from walls or ceilings as per the user manual.
