• If power is on, it will operate to chage capacitor (330µF/450WV) on controller and power relay will oper-
ate after about 2~5sec.
• If outdoor temp. is below 0°C, sump heater is operating for 20min.
• At the initial, It will be operated compressor after 1min. for preheating.
• 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 12Hz.
• If DC link voltage is not over DC 350V in 6 sec. in case of PFC on, it does not operating of compressor.
• If DC link voltage is not over DC 350V in 6 sec. in case of PFC on, it does not operating of compressor.
• 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.
• 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 low, it will change high speed in case of below AC193V, over 45°C of out-
door temp., and over fc, fh of comp. Freq.
