4.2.4 Prevention against condensation and insufficient heat exchange at the low
indoor fan speed.
When the indoor fan speed is set at the low fan speed, the compressor' s power is
restricted as in the low temperature cooling.
4.2.5 4-way valve
State: It is interrupted in cooling.
4.2.6 Anti-freeze protection
4.2.6.1 Condition for anti-freeze interruption: When the indoor heat exchanger
temperature is below the Anti-freeze Interruption Temperature £ ¨ 0¡æ £© and maintains for
10 s, the system is interrupted for the anti-freeze.
Action of anti-freeze interruption: The compressor is interrupted, the outdoor fan stops
and the indoor fan remains running.
Condition for anti-freeze left: When the indoor heat exchanger temperature rises to
the Anti-freeze Releasing Temperature(9¡æ ), the anti-freeze interruption is left.
4.2.7 Compressor discharge temperature too high protection
4.2.7.1 Conditions for the compressor discharge interruption protection: The
compressor discharge temperature is above or equal to 115
the compressor discharge interruption protection is activated.
Action of the compressor discharge interruption protection: Prompts are made on the
remote controller display screen and with the outdoor indicator light and the
compressor stops.
Conditions for the compressor discharge interruption protection left: When the
compressor discharge temperature drops below 92
interruption protection is left.
4.2.8 Overcurrent protection in cooling:
4.2.8.1 Conditions for overcurrent protection: When the current rises above or at the
Interruption Current Value for the Cooling Current Protection(23A£© and maintains for
10 s, the overcurrent protection is activated.
Action of the overcurrent protection: Prompts are shown on the screen on the remote
controller unit and by the indicator light on the outdoor unit. The compressor stops.
Conditions for overcurrent protection left: When the current drops below the Value of
the Current for the Cooling Current Protection Left(13A£© , the overcurrent protection is
left.
