- the earth wire to the cooler-convector/cooler-radiator structure using the screws
supplied (the minimum force of about 4N must be used when screwing-up
- make the electrical connections, as described in par. 2.4.

2.4 ELECTRICAL CONNECTIONS (Fig.6)
Before connecting the ventil radiator/fan coil to the mains, ensure that:
• The voltage and power frequency values match those speci ed on the appliance
plate data (2 0Vac /-15 , 50H
• The power line is equipped with an effective earth connection and is correctly
si ed for ma imum power consumption of the appliance
indicated on the plate data (minimum section of power cables equal to 1.5 mm
• An omnipolar disconnect device and adequate protection against overloads
and/or short-circuits must be added in compliance with national installation regulations.
It is essential to ensure that the appliance is NOT connected to the
mains before making any electrical connections or carrying out
maintenance.
• Fasten the earth cable to the appliance structure using the screw and washer
supplied (the minimum screwing force that must be e erted is about 4N (see
g. ref. A
• For the B0772 kit, connect the motor connector to the 3 pole connector and to
the X5 input on the electronic circuit board.
• For the B0774 kit, connect the motor connector to the X10 output on the
electronic circuit board.
• Connect the water probe connector on the fan coil unit to input X4. Make sure
the probe is correctly seated in its relative housing on the water battery.
• Connect the 2-pole connectors to the respective solenoid valve
cables (if present . On appliances for 2-pipe systems, connect only the connector
with red cable to the single water solenoid valve, while for appliances for 4-pipe
systems, connect the connector with red cable to the hot water solenoid valve
and the connector with green cable to the cold water solenoid valve.
• For kit B0774 and only on some models, connect the grill opening microswitch
cable to inlet X6 on the electronic board (eliminating any jumper
• connect the power cable to the terminal board and fasten it with
the cable grip. Use cables with a minimum section of 1.5 mm
• Connect the display board connector to input X9 on the electronic circuit board.
2.5 AIR TEMPERATURE PROBE INSTALLATION
To position the temperature probe ( g. 4 ref. A :
• pass the probe through the hole on the shoulder ( g. 4 ref. B
• insert the probe in the lower hole ( g. 4 ref. C
• the probe in the special hook ( g. 4 ref. D .
2.6 PRESENCE CONTACT INPUT
The free contact (not powered of a presence sensor (not supplied can be connected
to terminals A and B ( g. 5 , upon closure of which the selected ambient temperature
is automatically increased (in cooling or decreased (in heating by 2.5 C. When set
to 0 C, when the contact closes the appliance deactivates (stand-by .
This value can be changed in the factory or by an authorised service centre at the
request of the customer.
The input cannot be connected in parallel to one of another
electronic board (use separate contacts).
To connect the presence sensor, use double insulated cable with minimum
section of 2 0.5 mm and ma imum length 20 m (keep this connection
2
separate from the appliance s main power line .
2.7 SPECIAL FUNCTIONS
• Air sampling: in heating or cooling mode and with ambient temperature
above or below the required value respectively, the fan is powered for 1
minute at minimum speed and at intervals that can be set to between 1
and 60 minutes. In this way, the system is able to control the temperature
of the surrounding environment and reactivate more quickly if necessary.

GB
• Ambient temperature offset: in particular situations (e.g.: ceiling installed
appliances it may be necessary to offset the difference between the
temperature acquired by the electronic board and the actual temperature
of the room in which the appliance is installed (offset can be set between
5 C and -5 C .
Both of the above functions can be activated at the factory or by an
authorised service centre at prior customer request.
• Control blocking: to block the keys hold down the
together for 5 seconds. Repeat the operation to release.
2.8 CLOSING THE APPLIANCE
• Mount the aesthetic side panel on the ventil radiator/fan coil
• tighten the top screw fastening the side panel ( g. 1 ref. L or ref. F
• re t the air outlet safety grill ( g. 1 ref. A .
• Position the screw cap provided in the housing on the control panel ( g. 1 ref. H .

2.10 SETTING AUTOMATIC COOLING/HEATING MODE
Setting this type of adjustment enables the control to automatically select cooling
or heating mode, e cluding normal manual selection. This adjustment is particularly
suitable for 4-pipe appliances, and can be activated solely by a quali ed and
authorised installer. To activate this function, hold down the cooling/heating
selection key ( g. 7 ref. B for 10 seconds until the blue and red symbols light up
simultaneously ( g. 7 ref. C and D . This setting is also maintained in the event
of a power failure.
To deactivate the automatic cooling/heating function, press the cooling/heating
selection key again for 10 seconds. Then check that each time the key is pressed it

is possible to cycle through cooling only (blue indicator g. 7 ref. C on , heating only

The command makes the temperature regulation completely autonomous through
the AUTO, SILENT, NI HT and MAX programmes, with a probe positioned in the
lower part of the ventil radiator/fan coil, and guarantees anti-free e security even
when in stand-by.

3.1 SWITCHING ON/OFF
If there is a master switch on the mains power supply then it must be switched on.
To switch on the fan coil unit, press key
To switch off the appliance hold down key
No light signal means the unit is in stand-by mode (not running .
When the control is in this operating mode, protection against free ing is guaranteed.
If the ambient temperature drops below 5 C the hot water solenoid is activated and
the fan motor runs at minimum speed (AF .
