Operating and maintenance instructions

Infrared ray remote control unit

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.
  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-

perature  set  point,  the  unit  will
operate  in  cool  mode  so  as  to
keep  the  ambient  temperature
within the limits of its set point, +1
to +2°C for 1 hour.

Heat mode

In Sleep mode and heat operation, the unit
will operate in the following phase sequence:
1-2.
Phase 1 The unit will operate in heat mode
