Heating Operation - Fujitsu ARYG72LHTA Service Instruction

1-3. HEATING OPERATION

A sensor (room temperature thermistor) built in the indoor unit 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 6.0°C than a set temperature,
the compressor operation frequency will attain to maximum performance.
* If the room temperature is higher 1.0°C than a set temperature, the compressor
will be stopped.
* When the room temperature is between +1.0°C to -6.0°C of the setting temperature,
the compressor frequency is controlled within the range shown in Table2.
