3. ANTIFREEZING CONTROL (Cooling and Dry mode)
The compressor speed is decreased on cooling & dry mode when the indoor heat exchanger
temperature sensor detects the temperature lower than 4
°C
.
Then, the anti-freezing control is released when it becomes higher than Release temperature A.
(Table 22 : Anti-freezing protection operation / Release temperature)
4. COOLING PRESSURE OVERRISE PROTECTION
When the outdoor unit heat exchange sensor temperature rises to
67°C
or greater,
the compressor is stopped.
Then the compressor will be restarted after 3 minutes ST.
5. HIGH TEMPERATURE RELEASE CONTROL ( HEATING MODE )
In heating mode, the compressor speed is controlled based on the detection value
of the indoor heat exchanger temperature sensor.
