OR
When the FAN key is pressed repeatedly, the system can move to the minimum
speed (LOW), medium speed (MED) and high speed (HIGH) or to the (AUTO)
speed controlled by the microprocessor.
5) TO DIRECT THE AIR FLOW
To ensure optimum air distribution, adjust the horizontal blades and the vertical
blades in such a way that the air flow does not hit people directly. The vertical air
flow blades must be set manually before starting up the motorised blades.
Never adjust the motorised horizontal blades manually.
When the LOUVER key is pressed repeatedly, the horizontal blade is adjusted to 4
fixed blade positions, then a swinging blade movement will begin. If you wish to
stop the blade in a particular position, press the LOUVER key.
When the SWING key is pressed a swinging blade movement will begin. If you

OPERATING IN JUST VENTILATION MODE
This programme is used to move the room air and avoid stagnation. The ventila-
tion programme is particularly indicated as a support to heating systems without
fans, as when a stove is used to heat the room. All the hot air gathers by the ceil-
ing. When the unit is set in ventilation mode, the hot air is distributed uniformly
throughout the room.
