• If power is on, it will operate to chage capacitor on controller and power relay will operate after about
2~5sec.
• If outdoor temp. is below 0°C, preheater is operating for 1~5min.
• At the initial, It will be operated compressor after 1min. for preheating.
• The active power filter is designed to correct power factor(cos θ) and to regulate DC link voltage.
• It will be operated PFC circuit when the compressor freq. is over 30Hz and wattage is over 450 watt.
• The final operating freq. of comp. is set the lowest freq. that limited outdoor temp., discharge pipe temp.,
heat-sink temp., target freq., owing to CT.
• When the temp. of power module increases to 85°C, controller decreases Freq. of Comp.
• It will be changed the drive freq. of comp. according to temp. of indoor and outdoor.
• It will be changed the drive voltage of comp. according to operating frequency.
• It is only operated in the heating operation mode except defrosting operation.
• High speed
- Although fan motor speed is middle, it will change high speed in case of below AC193V, over 45°C of
outdoor temp., and over fc, fh of comp. Freq.
• Middle speed
- Nomal mode
• Low speed

•If compressor operates at some operation frequency, the operating frequency of compressor cannot be
changed within 30 seconds.
•Condition of compressor turned off
- When intake air temperature reaches +3°C above the setting temperature.
•Condition of indoor fan turned off
- While in compressor on:indoor pipe temp. < 30°C
•While in defrost control, between the indoor and outdoor fans are turned off.
•Compressor 2minutes delay
- After compressor off, the compressor can restart minimum 2 minutes later.

•When the Fuzzy key(=setting temp. key) is input after the initial setting temperature is selected, the Fuzzy
key value and intake air temperature at that time are compared to select the setting temperature automatically
according to the fuzzy rule.
•While in Fuzzy operation, the air flow speed of the indoor fan is automatically operated by Fuzzy logic.
