2. HEATING OPERATION
2-1 HEATING CAPACITY CONTROL
A sensor (room temperature thermistor) built in the indoor unit body will usually perceive
difference or variation between a set temperature and present room temperature, and
controls the operation frequency of the compressor.
* If the room temperature is lower by 6°F(3°C) than a set temperature, the compressor operation
frequency will attain to maximum performance.
* If the room temperature is higher 5°F(2.5°C) than a set temperatire, the compressor will be
stopped.
* When the room temperature is between +5°F(+2.5°C) to -6°F(-3°C) of the setting temperature,
the compressor frequency is controlled within the range shown in Table2.

3. DRY OPERATION
3-1 INDOOR UNIT CONTROL
The compressor rotation frequency shall change according to the temperature, set temperature,
and room temperature variation which the room temperature sensor of the indoor unit body has
detected as shown in the Table3.
However, after the compressor is driven, the indoor unit shall run at operation frequency of
30rps (18RLF), 30rps (24RLF), for a minute.
