Environmental protection

Eliminate packing in accordance
with the regulations in force on
environmental conservation.
During installation and maintenance, keep
in mind that HFC-410A and oil POE are
used.
Contains greenhouse effect fluorided gas
covered by the Kyoto protocol
For the type of gas and quantity per system,
see the identification plate.
GWP (Global Warming Potential): 2088.
1. The ON/OFF button allows turning the
air conditioning unit on or off.
2. Operating mode selector
There are five operating modes available:
System operating mode can be selected by
pressing the MODE button.
Model Operating mode
Cool only Vent. - Dry - Cool - Auto
Cool & heat Vent. - Dry - Cool - Heat - Auto
Fan mode
In FAN mode, only the fan is operative.
Fan speeds (low-medium-high) + auto can
be selected.
If AUTO is set in cool or heat operation, fan
speed will change in low-medium-high se-
quence, or high-medium-low automatically,
depending upon the differential between the
ambient temperature and its set points.
Dehumidification mode
In DRY mode, if the ambient temperature
is above its set point, the unit will operate
in cool mode with the fan at AUTO. If the

ambient temperature is below its set point,
the compressor and fan ON/OFF period
will go to a fixed repetition cycle, depending
upon the differential between the ambient
temperature and its set point.
Cool mode
In COOL mode, low-medium-high-auto fan
speeds can be selected.
Heat mode
In HEAT mode, low-medium-high-auto fan
speeds can be selected.
In order to avoid cold air originating in the
unit in heat operation, when the coil temper-
ature is too low, the fan will stop. As the coil
temperature rises as a result of compressor
operation, the fan restarts. This feature is
also operative when the unit is turned on,
delaying fan operation until the temperature
has reached the selected value.
Auto mode
In AUTO mode the system switches between
cool and heat modes automatically if the am-
bient temperature is above or below its set
point. The unit operates in cool mode if the
ambient temperature is above its set point,
and in heat mode if it is below said set point.
This is the operating mode recommended.
3. Adjusting ambient temperature
Press the + or - buttons to change the ambi-
ent temperature set point.
This should remain between 16 and 30°C.
- To select fan speed and air deflector posi-
tion.
Speeds available are Low - Medium - High.
Press the FAN button to achieve the desired
air flow. The FAN symbol shows the speed

selected.
Use the SWING button to control the air
deflectors. If pressed once, the deflector
is stationary; if pressed a second time, the
deflector sweeps to distribute air throughout
the room.
4. Timer operations
Clock
Il allows to adjust the hour and the minutes.
Pressing the key Clock once, the icon blinks
and can adjust the hour and the minutes.
Pressing the keys + and - the hourly pa-
rameters adjust. Once completed the adjust-
ment, to press the key Clock to confirm.
To use the timer, proceed as follows:
On/off timer
The on/off timing function is achieved by
pressing the T-ON and T-OFF buttons.
To start the unit at a determined time, press
the T-ON button in half minutes intervals until
the on time is achieved.
In the same way, to turn the unit off at a de-
termined time, carry out the same operation
by pressing the T-OFF button as many times
as necessary to achieve the required time.
5. Sleep function
The Sleep mode, which can be used in Cool
and Heat, is a program that controls the
ambient temperature at night.
Cool mode
In Sleep mode and cool operation, the unit
will operate in the following phase sequence:
1-2.
Phase 1 The unit will operate in cool mode
until the ambient temperature set
point is reached.
Phase 2 After reaching the ambient tem-
