1-1. COOLING OPERATION
1-1-1 COOLING 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 1 based on the fan speed mode
and the outdoor temperature.
* If the room temperature is 2 degC higher than a set temperature,
the compressor operation frequency will attain to maximum frequency.
* If the room temperature is 2.5 degC lower than a set temperature, the compressor will be stopped.
* When the room temperature is b2 degC to -2.5 degC of the setting temperature,
the compressor frequency is controlled within the range shown in Table1.
