Page 13: 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 14: 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 15: 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 16: 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 17: Forced Mode
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: 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. -
