Setting the fan speed
Press the FAN SPEED button.
By pressing the FAN SPEED button repeatedly, the indicator will switch from HIGH to MED and LOW.
The unit is designed and sized for optimum operation with the fan set to HIGH. (The figure shows the
MED speed setting.)
N O T E
In DRY mode, the fan speed changes automatically to LOW and cannot be changed (although the indica-
tor will still show the current setting).
Setting the louver direction
Pressing the LOUVER button starts the louver. The louver oscillates at approximately 70° from the horizontal to vertical position.
When the " " symbol moves, this indicates that the louver is oscillating.
When the louver oscillation function is not required, press the SWING LOUVER button again. The oscillator will stop (although not im-
mediately) at the angle indicated by the direction of the "
By commanding the louver to move to a specific position, it will move from the initial position to vertical and will then rise again to the
horizontal position, before finally moving to the position indicated by the user.
Fixed position
For cooling mode, the air outlet angle can be set to one of 5 different positions. In heating mode, it can be set to one of 7 positions.
Automatic oscillation position
The louver position indicators will move continuously according to the oscillation of the louver.
N O T E
• In heating mode, the louver angle changes automatically.
• There is a phase shift between the actual angle of the louver and the indicated on the LCD screen. When the SWING LOUVER
button is pressed, the louver does not stop immediately. It will move an oscillate again before stopping.
• To find out the exact louver angles, check the corresponding Catalogue for the unit installed.

Ventilation mode procedure
N O T E
• This function is only available when the total heat exchanger is connected*. When carrying out the following procedures without the
total heat exchanger connected, the NO FUNCTION indication will flash for 5 seconds.
• *Total heat exchanger: When adjusting the temperature, the indoor unit will release air from inside the room and replace it with air
from outside. To adjust the air from outside to the temperature setting inside the room, it is passed through the total heat exchanger.
The air pretreated (preconditioned) in this heat exchanger is routed to the indoor unit where it is conditioned and then circulated
into the room.
Ventilation
Press VENTI button
By pressing this button repeatedly, the indicator changes from A/C to VENTI and A/C+VENTI.
(The figure shows the A/C + VENTI setting).
N O T E
• If the system mode is changed to VENTI during individual air conditioning system operation, the
system will switch off.
• If the system mode is changed A/C during individual operation of the total heat exchanger, it will
switch off.
