MODE DESCRIPTION
COOLING Cools, dehumidifies and filters the room air. Maintains desired room temperature.
HEATING Heats and filters the room air. Maintains desired room temperature.
SMART Operates the appliance at COOLING, HEATING or DRY mode, maintaining desired
temperature dependent upon the room temperature.
DRY Dehumidifies and softly cools the room air. This mode is advisable to be used when
the room temperature is rather cool but the humidity is rather high.
FAN ONLY Re-circulates and filters the room air. Maintains constant air movement in the room.
SLEEP
The SLEEP mode will be canceled after being set for 8 hours. The set temperature
will be increased 0.5℃per hour during the first two hours in COOLING or DRY and
decreased 1℃per hour in the first three hours in HEATING.
AUTO FAN
The appliance automatically selects the indoor fan speed in accordance to the room
temperature. At the start, the appliance operates at high fan speed. As the room
temperature gets closer to the set temperature, the fan switches to a lower speed for
quieter operation.

OPERATION DETAILS
1. SAFETY CONTROL
 3 minutes delay for compressor
The compressor is ceased for 3 minutes to balance the pressure in the refrigeration cycle in order to
protect the compressor.
 59 seconds delay for reversing valve
The 4-way reversing valve delay for 59 seconds to prevent the refrigerant abnormal noise when the
HEATING operation is OFF or switched to other operation modes.
 Over-current control
The compressor will be switched OFF when it is over-current for 5seconds, and when the current is
normal and the compressor has been off for 3 minutes , the compressor will be turned ON.
 Freeze preventive control
When the indoor pipe temperature falls below –1℃during COOLING or DRY operation for 3
minutes, the compressor and outdoor fan motor turn OFF with buzzer 3 beeps . When the indoor pipe
temperature recovers to 5℃and the compressor has been off for 3 minutes, the compressor and
outdoor fan motor will be turned ON.
 Overheating protection system
When overloading occurs during the heating operation, this system controls the outdoor fan motor
and compressor according to the indoor pipe temperature to prevent the overloading of the
compressor and restrain the rise in high pressure. When the indoor pipe temperature exceeds 53℃,
the outdoor fan motor will be turned OFF, and when the indoor pipe temperature falls below 49℃,
the outdoor fan motor recovers to ON. When the indoor pipe temperature exceeds 63℃, the appliance
will be turned OFF with 4 beeps of buzzer and cannot recover automatically.
