• Preset temperature: 26°C
• Discharge Air Direction: SWING (up and down)
• Fan speed: AUTO

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.

Description
1. After the power ON/OFF button is pressed once, the relay and triac are turned ON or OFF per the remote
control setpoint.
– TRIAC is controlled per the fan speed selection.
– RELA Y is controlled per the operation mode selection.
2. If the power ON/OFF button is pressed once more, the relay and triac are turn off and the unit stops
operation.
3. The unit turns on or off according to the temperature setpoint by sensing the room air temperature through
thermistor.
4. If the fan speed selection is set to the auto position, the fan speed is automatically controlled according to
the temperature differance between room temperature and temperatur e setpoint.
5. If you press the ON/OFF button during operating the unit, Relay and LED is OFF and the unit is OFF.
