The unit automatically enters defrost mode from time to time to remove frost/ice that may form on the coil.
• When in defrost mode, the compressor continues to run, but no heat is provided to the space because
the indoor fan is shut off.
• When the outdoor temperature is very low, there may be a slight delay going from minimum to maximum
speed. Similar delays may occur when activating the oscillating flap.
After the unit is turned off the internal fan runs for an additional 60 seconds, then stops as both air flaps
close.

Airflow directional Control
• Press the T9 button to activate or deactivate the continuous oscillation of the air flap.
• Once activated, pressing the T9 button again will lock the flap in place.
This allows the end user to select the airflow direction best suited for their desired comfort.
Never attempt to move or force the �� by hand. Doing so will cause irreparable
damage.

Checking fan speed
• Fan speed can be adjusted by pressing the T5 button. Pressing this button several times changes the
speed in this order: low, medium, high and automatic.
• The higher fan speed provides greater the output, which also results in a slightly higher air sound level.
• By selecting automatic mode, the microprocessor adjusts the fan speed as required using the following
logic:
• As the difference between the actual room temperature and the end user setpoint increases, so does
the fan speed.
• As the room temperature decreases toward the setpoint, fan speed is reduced.
When in ����� ation mode, fan speed cannot be adjusted as the control will only operate the
fan at low speed.

SLEEP Mode (cooling / heating)
To activate Sleep Mode (cooling), first set the operational mode to cooling and set the desired room tem-
perature. Then press the T4 button.
• Ideally sleep mode is selected when you go to bed. The cooling setpoint is maintained for one hour.
• During the next two hours the cooling setpoint gradually increased while the fan runs low speed.
• At this point the cooling setpoint no longer changes.
To activate Night Mode (heating), first set the operational mode to heating and set the desired room tem-
perature. Now press the T4 button.
• Ideally night mode is selected just as you go to bed. The heating setpoint is maintained for one hour.
• During the next two hours the heating setpoint is gradually lowered while the fan is run low speed.
• At this point the cooling setpoint no longer changes.
Sleep mode is not available in ��������and ventilation mode. When in sleep mode pressing
the T3 button again will return the unit to the previous mode and temperature setpoint.
