5-2. HEATING OPERATION
5-2-1 HEATING CAPACITY CONTROL
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 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 temperature, the compressor
will be stopped.
* When the room temperature is between +2.5 °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 outdoor temperature.
