FUNCTIONS
1 System operation control
The units receives the user input (fan speed, flap position etc) through remote controller
which sends signal every time a button is pressed and in any case, automatically, every 5 minutes
.
During operation compressor speed can be subjected to change due to thermal load variations
or protection activations but in any case:
• The minimum time interval between an OFF and a ON operation is not lower than 3 minutes
• The minimum operating time is not lower than 3 minutes
• The maximum acceleration/deceleration rate is fixed at 20rpm /sec
• During the start-up compressor speed increases according to a defined rule which is
independent from the thermal load calculation.
2 Cool Mode Operation
In Cooling Mode, the operation of the compressor (CM), Outdoor Fan (FMO) and Indoor Fan (FMI) are
determined by:
1) the difference between the room air temperature (RAT) and the set point temperature (SPT)
2) the protection level at which the system is operatin
g
3) the thermal load in the room
NOTES
In addition to the temperature difference of above, the operation of the main components (CM, FMO,
FMI) is also controlled by protection function.
The minimum off time of compressor is 3 minutes.
The indoor fan can change speed only after it has operated at the same speed for 30 sec if in AUTO
and 1 sec for the other settings (High, Med, Low).
3 Heat Mode Operation
The Heating mode operation is similar to the Cooling mode operation. The CM, FMO and FMI are
controlled by the same parameters.
The FMI will not be turned on until the indoor coil temperature is warm enough to prevent the supply of
cold air (see COLD DRAFT PREVENTION feature for details).
The indoor fan can change speed only after it has operated at the same speed for 30 sec if in AUTO
and 1 sec for the other settings (High, Med, Low).

Pagina 9

4 Auto Mode Operation
In Auto Mode, the unit switches automatically between the Auto Cooling and Auto Heating in order to
maintain the room temperature (RAT) at the prescribed set point (SPT).
The switching between the two modes is according to the above graph and following table
If -3°C ≤Dt ≤-1°C and the compressor is off for more than 1 hour
If Dt ≤-3°C and compressor is off for more than 3 minutes
If 1°C ≤Dt ≤3°C and the compressor is off for more than 1 hour
If Dt ≥3°C and compressor is off for more than 3 minutes
Dt = RAT - SPT
Refer to the sections 1 COOLING MODE and 2 HEATING MODE for system operation details.
COOLING ---> HEATING
HEATING ---> COOLING

5 Dry Mode Operation
Dry operation remove moisture from indoor air running, in cooling mode, at a low level without reducin
g
the ambient temperature. This is done cycling ON and OFF the unit according to table below.

6 Fan Mode Operation
With this mode, the indoor fan is turned on while CM and FMO stay off all the time. The user can
select between 3 speeds: HIGH, MEDIUM and LOW.
7 Auto Fan speed
With this option selected, the indoor fan speed changes automatically according to the compressor
speed as shown in the following graph
s
In heating, to prevent the supply of cool air, the FMI speed is setted as shown only if the indoor
coil temperature ICT ≥34°C ( see COLD DRAFT PREVENTION feature for details )
If RAT goes over SET POINT by 1°C or less, for 1 hour, FMI is forced to LOW. If after
1 hour, RAT is still over SPT, FMI and compressor switch off.
Pagina 11

8 Forced Mode
In this mode the system operates (COOLING or HEATING mode – fixed settings) or is switched off by
means of the MODE button on the pcb receiver. The operation modes can be selected
pressing the button in a cyclic way (OFF COOL HEAT OFF…). The settings are:
COOLING mode
SET POINT temperature = 25°C
FAN SPEED = HIGH
FLAP POSITION = 3
HEATING mode
SET POINT temperature = 21°C
FAN SPEED = HIGH
FLAP POSITION = 4
This special mode is useful if the remote controller is missing or unusable.
When the remote controller operates, the function is automatically set off and the air conditioner
follows the remote controller instructions
9 Protection operations
9.1 Freeze-up
This protection prevents ice formation on the indoor coil heat exchanger. The protection is activated
as soon as the indoor coil temperature ICT decreases and acts by decreasing the compressor speed
The system exit this protection routine when ICT temperature rises above 5°C.
9.2 Cold draft
This feature prevents the supply of cold air forcing the indoor fan to a speed which cannot be changed
by the user.
If the ICT temperature goes down 32°C (in descending) or does not reach 37°C (in rising), the speed
fan is set as shown below.
9.3 Overheat internal exchanger
This feature prevents the build up of high pressure in the indoor heat exchanger during heating operatio
n
As soon as the indoor coil temperature (ICT) increases, compressor speed is reduced in order to avoid
heat exchanger overheating. System stops compressor operation when ICT reaches 60 °C
Pagina 12

9.4 Overheat outdoor exchanger
During cooling operation as soon as the outdoor coil temperature (OCT) increases, compressor speed
is reduced in order to avoid heat exchanger overheating. System stops compressor operation when OCT
reaches 65 °C
9.5 Compressor discharge temperature
During operation, as soon as the discharge temperature increases, (CDT) compressor speed is reduced
in order to avoid overheating of the motor. Compressor is stopped when CDT reaches 111°C
9.6 Compressor power-module overheating
The module temperature, detected by a built-in thermistor, is always monitored by the control system an
d
kept operating in a safe area. If temperature exceeds 100°C, operation is automatically stopped.
9.7 Compressor power-module overcurrent
Operation is automatically stopped in case of current driven to each motor phase greater than 9

10 Defrost
The defrost process is controlled by a detection algorithm designed in order to mantain optimal
utilization of the heat pump capacity especially during negative outdoor temperature conditions
.
• Compressor speed fixed
• Expansion valve opening fixed
• Outdoor fan switched off
• Indoor fan controlled by cold draft prevention
• Reversing valve switched off (cooling operation)
• Minimum defrost time interval is 6 minutes
• During HIGH POWER operation the defrost detection is ignored until this mode remains active
• System exits defrost protection at least after 6 minutes and only if the temperature of 14°C is reached
on outdoor coil. In any case it exits if at least 12 minutes are elapsed from the start of the defrost cycle.
• After defrost, the compressor starts run after 3 minutes although the fan and the resistance
switch on after 45 seconds.
11 I FEEL function
A
s standard configuration the air conditioner operates detecting the room temperature through the senso
r
equipped in the wireless remote controller (icon I FEEL shown on the display). This feature provides
a
personalised environment since the temperature can be detected where the remote controller is located.
