9. ELECTRONIC EXPANSION VALVE CONTROL

The most proper opening of the electronic expansion valve is calculated and controlled under the
present operating condition based on the Table 12.
The compressor frequency, the temperatures detected by the discharge temperature sensor, the
indoor heat exchanger sensor, the outdoor heat exchanger sensor,
and the outdoor temperature sensor.
( Table 12 : The pulse range of the electronic expansion valve control )
AO*G30LETL
AO*G36LETL
The expansion valve is set at 480 pulses after 120 seconds of stopping compressor.
At the time of supplying the power to the outdoor unit, the initialization of the electronic
