Frost Prevention of Indoor Unit

When the unit operates at low ambient temperature, frost may appear on the Evaporator. When the indoor coil temperature is lower than 0°C at the end of 10 minutes of continuous compressor operation from the start, the microcomputer of the unit stops the compressor to protect the unit from the frost. The control procedure for indoor coil freeze protection.

1) The compressor and outdoor fan turn off.

2) Indoor fan operates according to user set speed.

3) The normal operation returns when the indoor coil temperature is higher than 7°C or equal to 7°C.

(1) In Auto Mode

After the indoor fan is operated for 20 seconds in the Auto Mode the unit will operate automatically by selecting operating Mode according to the room temperature

(2) Selecting Operating Mode Again

Room temperature meets desired temperature and the compressor stops running over 30 minutes, then the unit selects operating Mode again.

3 min. Time Delay of Compressor

In normal operation, there is a time delay of three minutes between turn off and turning back on including initial power up.
