EN HOW TO INSTALL BATTERIES
●Remove trhe lid in the rear part of the
remote control unit.
TEMPERATURE SENSOR SELECTOR
●Under normal conditions the room temperature is
detected and checked by the temperature sensor placed
in the remote controller (I FEEL icon displayed ).This
function is designed to provide a comfortable room
temperature by transmitting the temperature control
command from the location next to you. When using this
function, the remote, control should always be pointed
at the air conditioner, therefore it should be placed in
a position in which it is visible by the indoor unit (for
example, do not put it in a drawer).
●It is possible to disable the remote controller room sensor
by pressing and holding the FAN/I FEEL button. In
this case the I FEEL icon on the remote controller display
lights off and only the sensor placed in the air conditioner
becomes active.
USING THE REMOTE CONTROL UNIT
●Insert two AAA alkaline batteries of
1,5 V-DC making sure that point in
the direction marked in the battery
compartment.
●Set the clock (see procedure on page
6).
Remote controller is now ready for
operation.
●The batteries last average more than
six months, anyway it depends on how much you use
the remote control unit.
Remove the batteries if you do not use the remote
control unit for more than one month.
Replace the batteries when the battery symbol appears
on the remote control ( )
●The batteries of the remote control contain polluted
substances. Exhausted batteries must be disposed

OPERATION WITH THE REMOTE CONTROL UNIT
When using the remote control unit, always point the unit
transmitter head directly at the air conditioner receiver.
The remote control unit transmits signals to the indoor
unit each time you press a key and at any temperature
change detected by the internal sensor. In case of
troubles (low batteries, remote control placed in
a position not visible by the indoor unit,...) room
temperature control is automatically switched to the
sensor of the indoor unit. In this case, the temperature
around the remote control unit may differ from the
temperature detected in the air conditioner position.

AUTOMATIC OPERATION IN MULTISPLIT
CONFIGURATION
When the air conditioning system configuration is multisplit
and there is more than one indoor unit connected, the
automatic mode operates as follows:
- the first unit that switches on the system also decides the
operation mode (cooling or heating) for all the other units
that will be switched on after the first one;
- when the system has been switched on in cooling mode
and one unit is activated in heating mode, an error will
be signaled for this unit (wrong operating mode). If the
same unit is switched on in “automatic” mode and the
desired temperature is lower than the detected ambient
temperature, the unit will operate in cooling mode, like the
other units of the system; on the contrary, if the desired
temperature is higher than the detected one, the unit will
operate in fan mode;
- when the system has been switched on in heating mode
and one unit is activated in cooling mode, an error will
be signaled for this unit (wrong operating mode). If the
same unit is switched on in “automatic” mode and the
desired temperature is higher than the detected ambient
temperature, the unit will operate in heating mode, like the
other units of the system; on the contrary, if the desired
temperature is lower than the detected one, the unit will
operate in fan mode.

occurs:
- ZONE A: changes if the difference between the room
temperature and the temperature set on the remote
control unit is at least 3°C..
- ZONE B: changes if the difference between the room
temperature and the temperature set on the remote
control unit is at least 1°C, one hour after the compressor
stop.
- ZONE C: never changes if the difference between the

1. Turn on the unit with the ON / OFF button
2. Press the button until the DEHUMIDIFYING symbol
appears on the display .
3. Press the buttons to set the desired temperature
( the temperature range is between 10 °C and 32 °C ).
•Use DRY operation when you want to reduce the
humidity in the room.
•Once the room temperature reaches the set level, the
unit repeats the cycle of turning on / off automatically.
•During DRY operation, the fan speed is automatically
set (Remote control lamp is ON) to maximize
dehumidification.
•When the room temperature drops below the set
temperature, the unit still continues to operate at a low
temperature and could therefore further reduce the room
temperature in small rooms.
•Dry operation is not possible if the indoor temperature
is less than 10 °C.
