SiK401004_A5 SPECIFICATIONS3. FUNCTIONFunction DescriptionMemory functionFor the air conditioners with this memory function setting, the units may startautomaticallyafter power failure reset or the main power supply is turned on again (when the unitrestarts , it will return to the same operation condition as that of the former operationstatus, and the mode and parameter are also kept the same.)Timing function it can make timing ON/ OFF separately, meanwhile, it can also make timing on circularlySelf-diagnosis with alarmfunctiononce unit has malfunction, the malfunction code will be indicated and alarm ringsimmediatelySleep function it can self control for saving energy in energy saving mode.Automatic function the fan of indoor unit can adjust fan speed automatically based on actual demand whencooling or heating under automatic modeCool air protection function the fan starts only when the temperature of indoor unit heat exchanger is higher thanindoor temperature under heating modeHigh/low Pressure Protection when suction pressure is too low or discharge pressure is too high, compressor will stopand unit displays malfunction codeOverload protectioncompressor has its own overheat protection, once the temperature of compressor ishigher than allowable level, compressor will stop and it can restart only whentemperature recovers.Over current protection once the current of compressor is higher that normal level, compressor will stop and unitdisplays malfunction codeDischarge hightemperature protectiononce the discharge temperature of compressor is higher than allowable level, compressorwill stop and unit displays malfunction code.Reverse (open) phaseprotectiononce the phase sequence of power supply is incongruent or the phase is absent, unitcan’t work.Anti-hightemperature protectiononce the heat exchanger temperature of indoor unit is too high, the compressor will stop.Timing ON/OFF display display and make timing turn ON/OFF timeFan speed display display the speed (high.medium.low) of fanFunction model display cooling mode.dehumidifying mode.heating mode.fan modeTesting display display testing modeTemperature display display room temperature and set temperature
