FUNCTIONS 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.
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.
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.
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 Operation according to COOLING mode ≥ SPT+2°C LEVEL 0 CM on FMO on < SPT+2°C LEVEL 1 FMI switches between L and off (30 seconds) ≥...
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 COOL HEAT OFF…). The settings are: COOLING mode SET POINT temperature = 25°C FAN SPEED = HIGH HEATING mode SET POINT temperature = 21°C FAN SPEED = HIGH...
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.

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.
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 3 etc).
JUMPERS CONFIGURATION Jumpers are located on the indoor PCB near the MODE button. Unit is shipped with jumpers set according to the following table: JUMPER STATUS open open for H/P models - closed for other versions open closed closed...
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...
15) Maintenance Address to each unit in order to avoid operation conflicts. Address is set acting on the dip-switches located on the indoor PCB and on the remote controller. The PCB settings must match the corresponding ones on the wireless remote controller How to change address of the air conditioner Dip switch is located on the indoor PCB near the buzzer.
16) Manual Unit Control and Led indicators 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.
17) Ws Imput Switch The WS switch status (open/closed) rules system operation in two different way. 16.1 WATER FLOW-RATE MODE This mode is available when the WS_FLG parameter is set to 2 (water flow rate type). Drain pump is not present. WS status affects system operation only when unit is ON and according to the following chart:...
