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 3 C than a set temperature, the compressor operation
frequency will attain to maximum performance.
* If the room temperature is higher 2.5 C than a set temperatire, the compressor will be
stopped.

* When the room temperature is between +2 C to -3 C of the setting temperature,
the compressor frequency is controlled within the range shown in Table2.
However, the maximum frequency is limited in the range shown in Figure 2 based on the
fan speed mode and the outdoor temperature.
( Table 2 : Compressor Frequency Range )
( Fig.2 : Limit of Maximum Frequency based on Outdoor Temperature )
* The room temperature is controlled 2 C higher than the setting temperature for 60 minutes
after starting the operation.
After 60 minutes, it is controlled based on the normal setting temperature.
