In COOL mode, the two indoor coil thermistor (one main and one sub) sense temperature ununiformity (super heat)
at the heat exchanger, And when temperature difference have developed, the indoor coil thermistors adjust LEV
opening to get approximate 10 degrees lower temperature than the target temperature in the table above, thus
diminishing super heat.
