1 Cool Mode Operation
In Cool mode , the operation of Compressor ( CM ) , Solenoid Valve ( SV ) and Indoor Fan ( FMI ) are determined by the difference between the Room Temperature (RAT) and the Set Point Temperature (SPT) as in the graph above.
Notes:
a. In this graph, the FMI is operating in the"Auto Fan Speed" setting. If the user has selcted the low, medium or high fan speed, the FMI will run constantly at that speed only.
b. In addition to the value of ( RAT-SPT ) , the operations of the relays are also controlled by protection delays.For example,(a) the minimum On/Off time of the ( CM ) is 3min respectively, and (b) the FMI can change speed only after it has operated at de same speed for 30sec.wen in autofan setting and 1sec. for H/M/L setting.
FUNCTIONS
GL
14
2 Heat Mode Operation
The Heating mode operation is similar to the Cooling mode operation.The compressor CM,solenoid valve SV and fan motor indoor 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 ( RAT - 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).
15
3 Auto (Cool/Heat) 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.
16
4 Dry Mode Operation
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
17
7) Forcede mode
means of the OPERATION button on the front panel. The operation modes can be selected pressing the button in a cyclic way (OFF Ö COOL Ö HEAT Ö OFF…). 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 B 30 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.
18
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
19
9.2 Overheat
This feature prevents the build up of high pressure in the indoor heat exchanger during heating
20
10) I Feel Function
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.
21
12) Diagnostic
With this feature is possible to have a visual signal that a trouble is occurring.
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.

13) JUMPERS CONFIGURATION
Jumpers are located on the indoor PCB near the MODE button.
Unit is shipped with jumpers set according to the following table:

14) CONTACTS FOR BUILDING AUTOMATION
INPUT CONTACT (J4 - green) - AVAILABLE ONLY IF "BOILER CONNECTION KIT" IS NOT INSTALLED
The status of this input affects system operation according to the following:
Contact OPEN : system does not operate (always OFF) – inputs from wireless remote controller are not processed Contact CLOSED: system operates in the normal way according to the inputs coming from wireless remote controller
OUTPUT CONTACT (J12)
This connector is directly tied to the contact (normally open) of a power relay which activates every time the following alarm condition occur:
RAT damaged
ICT damaged
In this case when alarm happens, on poles 1 and 3 of J12 connector, 220 VAC-50Hz are available. Max electrical load: 1A- 240VA

The push button switch and the LED indicators on display panel let the user to control the unit operation without a R/C (Remote Controller). Their operations are provided below.
Push Button Switch :
Use to cycle the operation mode of the A/C unit among COOL, HEAT and OFF modes, without using the R/C.
Every time this switch is pressed, the next operation mode is selected, in order:
- Off => Cool mode => Heat mode => Off => … (for heat pump model)
- Off => Cool mode => Off => … (for cooling only model)
- The A/C will start in High fan speed. The temperature setting is 25°C for cooling and 21°C for heating mode.
WARNING:
the OFF position does not disconnect the power. Use the main power switch to turn off power completely.
Led indicators :
1. Lights up during Timer operation.
1. Lights up when the Air conditioner is connected to power and ready to receive the Remote Control command.
2. Blinks continuously in case of any thermistor failure.
1. Lights up in Operation mode ( Note: OFF in standby mode).
