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
condition occur:
•RAT damaged
•ICT damaged
In this case when alarm happens, on poles 1 and 3 of J12 connector, 220 VAC-50Hz are available.
Max electrical load: 1A- 240VA

3-4 MAINTENANCE
Changing the Address of the Air Conditione
r
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.
How to change address of the air conditione
r
Dip switch is located on the indoor PCB near the buzzer.
Set the PCB to the address desidered
As default switches SW1 and SW2 are in off status (PCB factory state).
How to change address on Remote Control Uni
t
Dip switch is located on the battery compartment.
1) Pull out the door and remove the batteries.
2) Set the switch SW1 and SW2 according to the indoor PCB settings
(do not act on SW3 and SW4)
3) Insert the batteries and pull on the door
As default switches SW1 and SW2 are in off status (remote controller factory state).

4.FUNCTION
4-1 Cool Mode Operation
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. The indoor fan can change speed only after it has operated at the same speed for 30 sec if in AUTO and 1
sec for the other settings (High, Med, Low).
V
ALVE
18

4-2 Heat Mode Operation
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).
NOTES
1. After VALVE is switched off, the FMI runs for 30s in order to purge heat from the indoor coil.
2. The FMI will not be turned on until the indoor coil temperature is warm enough to prevent the supply of
cool air (see COLD DRAFT PREVENTION mode for details). The indoor fan can change speed only after it
has operated at the same speed for 30 sec if in AUTO and 1 sec for the other settings (High, Med, Low).
V
ALVE
19

4-3 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 5.1 COOLING MODE and 5.2 HEATING MODE for system operation details.
