3-3 CONTACTS FOR BUILDING AUTOMATION 3-3.1 INPUT CONTACT (J4 - green) 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 3-3.2 OUTPUT CONTACT (J12) This connector is directly tied to the contact (normally open) of a power relay which activates every time the following alarm... -
Page 17: Maintenance
3-4 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. -
Page 18: Function
4.FUNCTION 4-1 Cool Mode Operation VALVE NOTES 1. In this graph, the FMI is operating with the “Auto Fan Speed” setting. If the user has selected the Low, Medium or High fan speed, the FMI will run at that speed only. 2. -
Page 19: Heat Mode Operation
4-2 Heat Mode Operation VALVE The Heating mode operation is similar to the Cooling mode operation. The VALVE 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 20: Auto (Cool/Heat) Mode Operation
4-3 Auto (cool/heat) Mode Operation VALVE(COOL) VALVE(HEAT)) 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. -

4-7 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 23 4-8.2 Overheat This feature prevents the build up of high pressure in the indoor heat exchanger during heating operation VALVE (HEAT) VALVE (HEAT) A (°C) B (°C)

Page 24: I Feel Function
4-9 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. -
Page 25: Diagnostic
4-11 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... -
