9-11. Outdoor fan motor control
The AC fan motor turns ON/OFF, interlocking with the compressor.
[ON] The AC fan motor turns ON 5 seconds before the compressor starts up.
[OFF] The AC fan motor turns OFF 15 seconds after the compressor has stopped running.
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.
