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.
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).
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.
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 Operation according to COOLING mode ≥...
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 COOL HEAT OFF…).
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.

9.3 Overheat This feature prevents the build up of high pressure in the indoor heat exchanger during heating operation 237R A (°C) B (°C) C (°C)
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.
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...

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 Changing the Address of the Air Conditioner In case of more than one air conditioner operating in the same room, it may be necessary to assign an 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.
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.
18) DRAIN PUMP Pump operates when the unit is running in COOLING and DRY modes. The level detection is done through a float switch connected at the input FS (closed under normal condition, and opened when water overflow). System operation is according to the following chart: 10sec 0sec 0sec...
