signal from the indoor fan indicates low
rpm (approximately 300 rpm or less).

temperature of the indoor heat exchanger
goes below 5°C during cooling. Stops the
compressor if the temperature stays below
0°C for 4 minutes.
Lowers the operating frequency if the
temperature of the indoor heat exchanger
rises above the overheating temperature
during heating. Stops the compressor if the
temperature stays above the overheating
temperature for 1 minute at minimum
frequency.
