AUTOMATIC OPERATION
DEFROSTING OF OUTDOOR UNIT HEAT
EXCHANGER
When the outdoor temperature is low, frost or ice may
appear on the heat exchanger coil, reducing the heating
performance. When this happens, a protection function
for the heat exchanger defrosting is activated. During this
function operation, the fan of the indoor unit stops. Heating
operation restarts after several minutes. (This interval
will vary slightly depending on the room and outdoor
temperature).
HEATING PERFORMANCE
A heat pump conditioner heats a room by taking heat
from outside air. The heating efficiency will fall off when
the outdoor temperature is very low. If enough heat is not
obtained with this air conditioner, use another heating
appliance in conjunction with it.

Example of operation diagram in the (Auto) mode
with the set room temperature at 23°C.
NOTE
The air conditioner changes the operation mode (from cool
to heat or vice versa, if one of the following conditions
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
room temperature and the temperature set on the remote
control unit is no more than 1°C.
1. Set the or selector to AUTO (symbol on the
display; also the symbol or remains displayed).
2. Press the
+/- buttons (temperature selection) to set the
desired temperature (the temperature range is between
32 °C max. and 10 °C min.).
When this setting is selected, the air conditioner will operate
automatically switching to the COOL or HEAT mode as
appropriate (regardless of the symbol displayed).
THE DISPLAY SHOWS THE
SELECTED TEMPERATURE.
AFTER 5 SECONDS FROM THE
REQUIRED TEMPERATURE SETTING
THE DISPLAY WILL SHOW THE ROOM
TEMPERATURE AGAIN.
3. Press the FAN selector button to the setting you want.
During Automatic Operation (+ IFEEL ON) the set
temperature is understood as perceived one, then the
system is automatically adjusted not only according to the
air temperature, but also based on the relative humidity,
according to the “humidex” index.
Verify that the unit is connected to the
main power and the STANDBY lamp is
light up.
1. Set the selector to COOL (symbol
on the display).
2. Press the +/- buttons (temperature
selection) to set the desired temperature
(the temperature range is between 32 °C
max. and 10 °C min.).
HOW TO SET THE PRESENT TIME
HEATING
1. Press the button ST three times.
The time indication alone flashes.
2. Press the H button until the present time hour is
displayed. Press the M button until the present time
minutes are displayed. The display will automatically
stop flashing.
1. Set the selector to HEAT (fixed or blinking symbol
on the display.
2. Press the +/- buttons (temperature selection) to set
the desired temperature (the temperature range is between
32 °C max. and 10 °C min.).
THE DISPLAY SHOWS THE
SELECTED TEMPERATURE.
AFTER 5 SECONDS FROM THE
REQUIRED TEMPERATURE SETTING
THE DISPLAY WILL SHOW THE ROOM
TEMPERATURE AGAIN.
3. Press the FAN button to select the fan speed.
For several minutes after the start of heating operation, the
indoor fan will stop until the indoor heat exchanger coil has
warmed up sufficiently. This is because the COLD DRAFT
PREVENTION SYSTEM is operating. During this period,
the STANDBY lamp remains lit.

Generally the fan stops when the set temperature is
exceeded (when you have selected the fixed HEATING
symbol ).
HEATING RECIRCULATION FUNCTION
If you want to let the fan run even after the set temperature is
exceeded, for example, in order to make the heating, coming
from a nearby source, circulate (eg. fireplace installed under
the air conditioner), press the selector until the blinking
HEATING symbol is displayed.
