(1) When the remote controller is lost, damaged or the battery is discharged, the Emergency operation can be
used to run the unit.
(2) The setting conditions of Emergency operation are as follows.
• Operation mode: AUTO
• Preset temperature: 26°C
• Discharge Air Direction: SWING (up and down)
• Fan speed: AUTO ¡Y ou cannot operate with remote contr oller.
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 contr ol procedur e 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.
(Indoor coil temperature)
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.
Indoor Fan Motor Starting
When indoor fan motor is on, it always starts at normal speed and then it operates desired speed.
