Indoor Fan
When the unit operates at low ambient temperature, frost may appear on the Ev aporator. 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.

Description
1. After the power ON/OFF button is pressed once, the rela y and triac are turned ON or OFF per the remote
control setpoint.
– TRIAC is controlled per the fan speed selection.
– RELAY is controlled per the operation mode selection.
2. If the power ON/OFF button is pressed once more, the rela y 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 temperature setpoint.
