In COOL operation, the two indoor coil thermistors (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 degree to get approximate 10 degrees lower temperature than the target temperature in the table
above, thus diminishing super heat.
(b) Reference value of LEV standard opening degree
(COOL/ HEAT pulse)
