Page 15: Function
5.FUNCTION 5-1 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. -
Page 16: Heat Mode Operation
5-2 Heat Mode Operation HEAT PUMP MODELS 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). -
Page 17: Auto (Cool/Heat) Mode Operation
5-3 Auto (cool/heat) Mode Operation HEAT PUMP MODELS 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 5.1 COOLING MODE and 5.2 HEATING MODE for system operation details. -
Page 18: Dry Mode Operation
5-4 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 ≥... -
Page 19: Forced-Made
5-7 Forced Mode In this mode the system operates (COOLING or HEATING mode – fixed settings) or is switched off by means of the MODE button of the indoor unit control board. The operation modes can be selected pressing the button in a cyclic way (OFF COOL HEAT OFF…). - Page 20 5-9 Protection operations in Heat Mode HEAT PUMP MODELS 5-9.1 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.

Page 22: I Feel Function
5-10 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. -

5-12 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... -

Page 26: Maintenance
5-15 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. The PCB settings must match the corresponding ones on the wireless remote controller. -
