1-2. HEATING OPERATION

1-2-1 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.
The maximum frequency is limited in the range shown in Figure 2 based on the outdoor temperature.
.
If the room temperature is lower 3 °C than a set temperature,
the compressor operation frequency will attain to maximum frequency.
.
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 Table 2.
