Wall mounted type (SKM).4-way ceiling cassette type (STM).Ducted type (SRRM).(4) Inverter (Frequency converter) for multi-steps power control¡ Heating / CoolingThe rotational speed of a compressor is changed in step in relation to varying load, to interlock with the indoor and outdoor unitfans controlled to changes in frequency, thus controlling the power.¡ Allowing quick heating/cooling operation during start-up period. Constant room temperature by fine-tuned control after theunit has stabilized.(5) Fuzzy controlFuzzy control calculates the amount of variation in the difference between the suction air temperature and the setting temperaturein compliance with the fuzzy rules in order to control the air capacity and the inverter frequency.(6) Self diagnosis functionWe are constantly trying to do better service to our customers by installing such judges that show abnormality of operation asfollows.
