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 .
(Table 18 : Anti-freezing Protection Operation / Release Temperature)

or 12°C
Less than 10°C

*1. When the temperature rises.
*2. When the temperature drops.
4. COOLING PRESSURE OVER RISE PROTECTION
On cooling mode, the compressor frequency is controlled as following based on the
detection value of the outdoor heat exchanger temperature sensor.
