Note: Use alkaline AAA batteries only.
1. The ON/OFF button allows turn-
ing 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 tempera-
ture 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 +C or -C buttons to change the
ambient 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
The remote control unit is equipped with a
timer that sets the on and off times of the
unit.
The operational configurations stored in the
remote control unit will be the predominating
parameters upon turning the unit on.
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 hour intervals until
the on time is achieved.
The unit will start once the programmed
time has elapsed, and which time will be
memorised by the unit.
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.
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
Phase 2 After reaching the ambient tem-
In Sleep mode and heat operation, the unit
will operate in the following phase sequence:
1-2.
