FUNCTIONS
1) Cool Mode Operation
In Cooling Mode, the operation of the compressor (CM), Outdoor Fan (FMO) and Indoor Fan (FMI) are
determined by the difference between the room air temperature (RAT) and the set point temperature (SPT)
as shown in the graph.
NOTES
1. In this graph, the FMI is operating with the “Auto Fan Speed” setting. If the user has selected the Low,
Medium or High fan speed, the FMI will run constantly at that speed only.
2. In addition to the temperature difference of above, the operations of the main components (CM, FMO,
FMI) is also controlled by protection delays. That is: - the minimum off time of compressor is 3 minutes. -
- 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).
F
11

2) Heat Mode Operation
The Heating mode operation is similar to the Cooling mode operation. The CM, FMO and FMI are mainly
controlled by the value of (RAT – SPT). In the graph above, the FMI is operating in AUTO speed mode.
Therefore, the FMI speed changes automatically according to the (RT - SPT).
NOTES
1. After the CM has stopped, the FMI runs for 30s in order to purge heat from the indoor coil.
2. The FMI will not be turned on until the indoor coil temperature is warm enough to prevent the supply of
cool 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).
12

3) 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.
Refer to the sections 1.COOLING MODE and 2.HEATING MODE for system operation details.
13

4) Dry Mode Operation
Dry operation remove moisture from indoor air running, in cooling mode, at a low level without
reducing the ambient temperature. This is done cycling ON and OFF indoor and outdoor units
according to below.
ROOM DRY LEVEL
TEMP
≥SPT+2°C LEVEL 0 Operation according to COOLING mode
CM on
< SPT+2°C LEVEL 1 FMO on
≥SPT-1°C FMI switches between L and off (30 seconds)
RV off
CM switches 9 minutes off and 3 minutes on
< SPT-1°C LEVEL 2 FMO switches 9 minutes off and 3 minutes ON
≥15°C FMI switches off and L during CM operation
RV off
CM off
< 15°C DRY OFF ZONE FMO off
FMI off
RV off
SPT = Set Point Temperature
5) Fan Mode Operation
With this mode, the indoor fan is turned on while CM, FMO and RV stay off all the time.
The user can select between 3 speeds: HIGH, MEDIUM and LOW.
6) Auto Fan speed
With this option selected, the indoor fan speed changes automatically according to the difference
between the detected air temperature (RAT sensor) and the set point (SPT):
COOLING MODE
2 ≤(RAT – SPT): HIGH speed
1 ≤(RAT – SPT) <2: MEDIUM speed
(RAT – SPT) <1: LOW speed
HEATING MODE
2 ≤(SPT - RAT): HIGH speed
(SPT - RAT) <2: MEDIUM speed
NOTE
SPT = Set Point Temperature
14

7) Forced Mode
In this mode the system operates (COOLING or HEATING mode – fixed settings) or is switched off by
means of the OPERATION button on the front panel. The operation modes can be selected
pressing the button in a cyclic way (OFF ÖCOOL ÖHEAT ÖOFF…). The settings are:
COOLING mode
SET POINT temperature = 25°C
FAN SPEED = HIGH
HEATING mode
SET POINT temperature = 21°C
FAN SPEED = HIGH
See also paragraph 15 for additional details.
8) Protection operations in Cool and Dry Mode
8.1 Freeze-up
This protection prevents ice formation on the indoor coil heat exchanger. The protection is activated by
the indoor coil temperature (ICT sensor) and only after 6 minutes of compressor operation. This
protection acts in 2 levels:
LEVEL 1
INDOOR FAN SPEED: ANY (as selected from remote controller)
COMPRESSOR: ON
OUTDOOR FAN: cycling (30 seconds ON B30 seconds OFF).
DRAIN PUMP: operates according to paragraph 17
LEVEL 2
INDOOR FAN SPEED: ANY (as selected from remote controller)
COMPRESSOR: OFF for at least 6 minutes and until ICT ≥8°C
OUTDOOR FAN: OFF for at least 6 minutes and until ICT ≥8°C
DRAIN PUMP: always ON ( stops when exiting the protection)
The system exit this protection routine when ICT temperature rises above 8°C.
15

9) Protection operations in Heat Mode
9.1 Cold draft
This feature prevents the supply of cold air forcing the indoor fan to a speed which cannot be changed
by the user. As soon as the protection mode is exited speed can be changed manually through the
remote controller. The protection acts in the following
9.2 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.
During DEFROST OPERATION the main components operates according to the following chart:

10) I FEEL Function
As standard configuration the air conditioner operates detecting the room temperature through the
sensor 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. It is possible to de-activate this option pressing the I FEEL button on the
remote controller. In this case the I FEEL icon is no longer displayed and room temperature is
detected trough the sensor included in the indoor unit.
11) NIGHT Function
When this function is active, room temperature changes automatically to compensate for body
temperature variations while sleeping. After 10 hours of operation system switches automatically to
OFF state. This mode of operation is available both in COOLING and HEATING mode.
18

12) Diagnostic
With this feature is possible to have a visual signal that a trouble is occurring.
This mode is always active and the signalling is made through the display board LEDS .
In case of no troubles the LEDS status follows its normal function.
NOTES
 The troubles are showed according a priority list that is in case of more than one
trouble present, is always showed, at first, the one with the highest priority (123 etc).
 Sensor damaged means a situation where sensor is short-circuited or opened.
 In case of damaged sensors, the system (CM, FMO, FMI etc), if in OFF state, does not start.
 WRONG MODE SELECTED means a situation where the operating mode chosen with remote controller
does not comply with the one allowed by jumpers settings.
