Warning
Management of the appliance with the touch-screen display
Objects or structural obstacles (furniture, curtains,
plants, leaves, blinds, etc.) must not obstruct the normal
air flow both from the internal and from the external grids.
Do not lean against, or worse sit on, the body of the
conditioner, this would damage the appliance.
Do not move the horizontal air outlet flap manually. Always
use the remote control to perform such operation.
In the event of water leaks, turn off the appliance and
disconnect the electric power supply. Call the nearest
service centre.
During heating mode, the conditioner eliminates
periodically any ice formed on the external battery. In
such situation, the machine keeps on working but it
does not dispense warm air to the room. This phase
can last 3 up to maximum 10 minutes.
The appliance must not be installed in rooms where
explosive gases develop or where there are humidity
and temperature conditions that exceed the maximum
levels reported on the installation manual.
Clean the air filter regularly as described in the specific
paragraph.
Normally, the display shows the operating status (see
Description of machine functioning paragraph) as well as
any alarms (see Display alarms paragraph).
In addition, it is possible to select the various functions by
pressing the symbols.

Managing the appliance with the remote control
Description of machine functioning
It is possible to select the various modes by pressing the
buttons ( see Description of machine functioning paragraph).
The remote control provided has been designed to be
functional and resistant, however it must be handled
cautiously.
Avoid:
- leaving it exposed to rain, pouring liquids on it or
dropping it into water
- hitting it or dropping it on hard surfaces
- leaving it under the sun
- placing obstacles between the remote and the
appliance while using it.
In addition:
- if there are other appliances using remote controls in
the room (TV, radios, stereos, etc.), interferences may
occur
- electronic or fluorescent lamps can interfere with
communication between the remote and the appliance
- remove the battery if not using the remote for a long
time.
Only CR2012 3V dry lithium batteries must be used
(supplied). Used batteries must be handed over to
the specific collection areas as arranged by the Local
Authorities for this type of waste.
In order to insert the batteries, open the specific cover
in the bottom part of the remote. The battery must be
inserted respecting polarity. Once the battery is inserted,
close the cover.
In order to manage the appliance using the remote control
and the touch-screen, the main switch on the electrical
power supply line must be turned on (its exact position will
be best known by the technician who installed the appliance)
or the power supply plug must be connected to the system
socket.
Once such operations have been performed, it is possible
to manage the system using the symbols on the touch-
screen or the remote control. In order to transmit commands
to the internal unit, the top part of the remote must point
towards the display of said internal unit. The reception of
the command is confirmed by a beep and by the display.
The maximum distance for the remote control to work is
approximately 8 metres.
General start-up and management
Battery insertion
Key/Display Operation
The buttons on the remote and the keys on the touch-screen display have the same function.
When the appliance is on, the setpoint is shown on the 3 digits of the display.
• It is possible to adjust the setpoint between 16 and 31°C.
Avoid setting the temperature too low or too high as, in addition to being unhealthy, it's a waste of
energy.

Key/Display Operation
Switching the appliance on and off
It is possible to switch the appliance on or off (stand-by) by pressing the specific button. The control system of the
appliance is equipped with a memory, so settings won't be lost if the appliance is switched off or in the event of low
voltage. The button must be used to activate or deactivate the appliance for short periods of time.
In case of long periods of inactivity, the appliance must be deactivated disconnecting either the main switch or the
plug from the socket.
Well-being button (economic automatic mode)
By choosing this mode on the appliance, it is set so as to obtain the best level of comfort in the room. The conditioner
selects the mode automatically (cooling or heating) according to the temperature set and ventilation speed according
to the temperature of the room.
Cooling only mode
• In this mode, the appliance dehumidifies and cools the room.
• It is possible to set the desired temperature between 16 and 31°C and, if such temperature is lower than the room
temperature, the compressor starts up after three minutes (maximum) and the appliance starts dispensing cool
air, maintaining ventilation active even if the setpoint has been reached.
Dehumidification only mode
In this mode, the appliance dehumidifies the room. Selecting this mode is useful during mid-seasons, that is to say
during those days (e.g. rainy ones) when the temperature is rather pleasant, but excess humidity causes discomfort.
This mode ignores both room temperature and ventilation speed settings. The latter is always set to a minimum. It is
normal for the appliance to work intermittently.
Ventilation only mode
By selecting this mode, the compressor is not activated and the appliance does not intervene on room temperature or
humidity. IT is possible to choose the fan speed.
Heating only mode
• In this mode, the appliance heats the room.
Set on heating only mode, the appliance defrosts the evaporative battery periodically if necessary. During this
phase, the conditioner does not dispense warm air, even if its internal organs are on except for air ventilation.
• It is possible to set the desired temperature between 16 and 31°C and, if such temperature is higher than the
room temperature, the compressor starts up after three minutes (maximum) and the appliance starts dispensing
warm air.
Nocturnal well-being button
While the appliance is on in the selected cooling or heating mode, it is possible to choose different functions by
pressing the button in order to maximise noise reduction, energy saving and nocturnal well-being regulation.
In this mode, ventilation is set on minimum speed.
This mode should be activated right before going to sleep.
• In cooling mode, the set temperature is risen by 1°C after one hour and by another degree after two. After the
second hour, the temperature is no longer changed and, after six hours, the appliance is put in stand-by.
• In heating mode, the set temperature is lowered by 1°C after one hour and by another degree after two. After the
second hour, the temperature is no longer changed and, after six hours, the appliance is put in stand-by.
This function is not available for dehumidification only, ventilation only and economic automatic modes and can be
excluded any time (ideally once awake) by pressing the button again.
If the Timer has also been set, the appliance will turn off at the set time.
Control of air flow direction
By pressing the specific button, it is possible to select the continuous oscillation of the mobile air outlet flap - in such
case, the symbol on the display is lit - or to block it in any position.
IMPORTANT: The mobile flap must never be moved manually. In cooling and dehumidification modes the position
of the flap is reset every 30 minutes, in order to prevent dew from forming.

Key/Display Operation
Fan speed control (models 8 and 10)
By pressing this button, the speed changes according to the following sequence: Minimum, Medium, Maximum and
Automatic.
The higher the speed, the better the performance, though the appliance will be more noisy. By selecting the Automatic
speed (which can be visualised by sliding the 3 speed bars on the display), the microprocessor regulates the speed
automatically, increasing or decreasing it according to the difference between the room temperature and the set
temperature. It is not possible to control the speed while in dehumidification only and nocturnal well-being mode, as the
appliance can only work in low speed.
12 HP inverter model power regulation
The power provided by the appliance can be set to 5 positions by pressing this button sequentially: Minimum, Medium,
Maximum, Dual Power and Automatic.
The higher the power set, the higher the performance of the appliance, but the lowest its quietness.
The Dual Power function (that can be recognised through flashing of the 3 speed bars on the display and sliding of the
7 bars, red or blue, of the digital thermometer), only available for heating and cooling, provides a 30-minute Overboost.
By setting the Automatic position (that can be seen by scrolling the three speed bars on the display) the on-board
microprocessor regulates power automatically, and increases it according to the deviation between room temperature
and set temperature. In dehumidification only and nocturnal well-being modes power control is not possible because
the appliance can operate only at minimum power.
Timer mode setting
• The appliance offers Users the chance to programme its activation and deactivation according to their needs.
• While the conditioner is on, it is possible to programme the switch-off time by pressing the Timer button and
setting the number of hours (1 to 24) after which the appliance will be put in stand-by.
• When the conditioner is off, it is possible to programme the switch-on time by pressing the Timer button and
setting the number of hours (1 to 24) after which the appliance will start-up.
• Press the button to confirm.
Touch-screen display key lock
• The key lock is activated by keeping the Timer symbol on the touch-screen display pressed for three seconds.
Any action is prevented by the user. The stand-by symbol flashes at 1 second intervals.
• To deactivate the lock, keep the Timer symbol pressed for three seconds again.
Any key on the remote control deactivates the lock!

Advice for energy saving
Problem diagnosis
- Always keep filters clean (see Maintenance and
Cleaning chapter).
- Keep doors and windows closed
- Avoid direct sunlight in the room (use curtains, pull
down the blinds or close the shutters)
- Do not obstruct the air flow (inwards and outwards)
as, on top of affecting performance, it prevents the
system from working correctly and it may cause
irreparable damage to the appliance.
It is very important that the User is capable of distinguishing
problems or anomalies from normal functioning. The most
common problems can be solved by the User following
simple procedures (see Troubleshooting paragraph),
whereas it is necessary to contact the Service Centre for
some of the alarms.
We would like to remind you that any reparation attempt
performed by unauthorised personnel immediately invalidates
any warranty.
- The compressor does not start again before a certain period
of time (approximately 3 minutes from the previous stop). The
delay between stops and reactivations has been arranged in
order to protect the compressor from too frequent activations.
- During heating mode, it is possible that warm air is dispensed
a few minutes after the compressor has been activated. If the
fan were to start together with the compressor, cold air would
be dispensed to the room (which could lead to discomfort for
those in the room) as the appliance is not fully operational yet.
If you lose the remote control, if it brakes or if the batteries run out,
the appliance can be managed using the touch-screen display.

In case of malfunctioning, please refer to the following table. If,
after performing the suggested checks, the problem is not solved,
please contact the authorised technical assistance.
An alarm code appears on the display in case of anomalies. Some
of the functions remain active nonetheless (see FUNCTIONING
column).
The only way to solve the problem is to disconnect and reconnect
the appliance. If the alarm still appears, please contact the
authorised technical assistance.

the appliance hasn't intervened (if it has, reset it). If the problem
repeats immediately, please call the Service Centre and avoid
trying to make the appliance work.
Batteries ran out Check that the appliance can be turned on using the touch-
screen display and substitute the batteries.
The appliance
does not cool/
heat enough.
The temperature set is too high or too
low. Check and adjust the temperature.
The air filter is clogged Check the air filter and clean it if necessary
Check that there are no other obstacles
of the air flow both inside and outside. Remove anything that might block the air flow.
The thermal refrigeration load has
increased (for example, a door or
a window has been left open or an
appliance has been installed in the
room which generates a lot of heat).
Try to reduce the thermal refrigeration load of the room following
instructions below:
Cover large windows exposed to sunlight with curtains or with
external maskings (blinds, porches, reflecting films, etc.);
The room must remain closed for as long as possible;
Avoid using halogen lamps or other high energy consumption
appliances such as small ovens, steam irons, cooking plates etc.

OF Maximum level float
intervention
During cooling and dehumidification, electronics switches the
compressor off and keeps the water distribution system active
with the battery - together with the fan - to disperse excess
water. During heating, condensations should drain freely
through the specific pipe. In the event of an alarm, check that the
condensation pipe is not bent or obstructed, thus preventing the
water from flowing out.
* for model 12 HP: lack of communication between the main,
power, driver or display boards
