5. COOLING OPERATION
A sensor (room temperature thermistor) built in an indoor unit body usually perceives
difference or variation between set temperatu re and present room temperature,
and controls operation frequency of the compressor.
* When the room temperature is 7°F(3.5°C) higher than a set temperature, the compressor operation
frequency will attain to maximum performance.
* When the room temperature is 1°F(0.5°C) lower than a set temperature, the compressor will be stopped.
* When the room temperature is between +7°F(+3.5°C) to -1°F(-0.5°C) of the setting temperature,
the compressor frequency is controlled within the range shown in Table 1.
6. DRY OPERATION
Compressor frequency is defined by the set temperature
and room temperature as below.
