In COOL operation, the indoor coil thermistors (main and sub) sense temperature ununiformity (super heat) at
the heat exchanger, and when temperature difference develops, the indoor coil thermistors adjust LEV opening
degree to get approximate 18°F (10°C) lower temperature than the target temperature in the table above, thus
diminishing super heat.
