(3). ANTIFREEZING CONTROL (Cooling and Dry mode)
The compressor frequency is decrease on cooling & dry mode when the indoor heat exchanger
temperature sensor detects the temperature lower than Temperature .
Then, the anti-freezing control is released when it becomes higher than Temperature .

(4). COOLING PRESSURE OVERRISE PROTECTION
(Table 20 : Cooling Pressure Over Rise Protection Function Temperature)
When the outdoor unit heat exchange sensor temperature rises to temperature or greater, the
compressor is stopped and trouble display is performed.

(5). HIGH TEMPERATURE RELEASE CONTROL ( HEATING MODE )
On heating mode, the compressor frequency is controlled as following based on the
detection value of the indoor heat exchanger temperature sensor.
