Functions

• Room temperature sensor. (Thermistor)

• Pipe temperature sensor. (Thermistor)

• Maintain the room temperature in accordance with the Setting Temp.

• Indoor fan is delayed for 5 sec at the starting.

• Restarting is for approx. 2 minutes.

• Super High, High, Med, Low

--- Lights up in operation

--- Lights up in Sleep Mode

--- Lights up in Timer Mode

--- Lights up in Preheat Mode (for Heating Model)

--- Lights up in Plasma Air Clean Mode

• Intermittent Operation of fan at low speed or off.

• The fan is switched to low(Cooling), low(Heating) speed.

• The unit will be stopped after 1, 2, 3, 4, 5, 6, 7 hours.

• The fan is switched to intermittent or irregular operation

•

The fan speed is automatically switched from high to low speed.

• 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

- Although fan motor speed is middle, it will change Low speed in case of over AC 270V, over 21°C

(Heating Mode) of outdoor temp. below 24°C (Cooling Mode) of outdoor temp.
