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
16

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
17

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.

4-4 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.

4-5 Fan Mode Operation
With this mode, the indoor fan is turned on while cooling and heating valve stay off all the time. The user can
select between 3 speeds: HIGH, MEDIUM and LOW.
4-6 Auto Fan speed
With this option selected, the indoor fan speed changes automatically according to the difference between
the detected air temperature (RAT sensor) and the set point (SPT):
COOLING MODE
2 ≤(RAT – SPT): HIGH speed
1 ≤(RAT – SPT) <2: MEDIUM speed
(RAT – SPT) <1: LOW speed
HEATING MODE
2 ≤(SPT - RAT): HIGH speed
(SPT - RAT) <2: MEDIUM speed
NOTE
SPT = Set Point Temperature
19

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 ÖCOOL ÖHEAT ÖOFF…). The settings are:
COOLING mode
SET POINT temperature = 25°C
FAN SPEED = HIGH
HEATING mod
e
SET POINT temperature = 21°C
FAN SPEED = HIGH
4-8 Protection operations in Heat Mode
5-8.1 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. The protection acts in the following
