Fujitsu ASYG12LMCE Service Instruction

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 27 : 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 and the outdoor fan motor are stopped and trouble display is performed.
5. HIGH TEMPERATURE RELEASE CONTROL ( HEATING MODE )
01-21
Outdoor temperature
Over than 10°C *1

On heating mode, the compressor frequency is controlled as following based on the
detection value of the indoor heat exchanger temperature sensor.
