1-1. COOLING OPERATION
1-1-1 COOLING CAPACITY CONTROL
01-01
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 2°C higher than a set temperature,
the compressor operation frequency will attain to maximum performance.
* If the room temperature is 2.5°C lower than a set temperature, the compressor
will be stopped.
* When the room temperature is between +2°C to -2.5°C of the setting temperature,
the compressor frequency is controlled within the range shown in Table1.
