2 water valves, one for summer (cooling) and one for winter (heating) mode.
The three selectors can be positioned in all possible combinations, as the
respective functions are independent of one another.
2.3 INSTALLATION
Slide the control panel onto the grill (fig.2).
To install the connection box:
- open the box (fig. 3 ref. B);
- insert the lower lug into the special slot (fig. 3 ref. C) on the side of the appliance;
- hook the upper part of the box to the side (fig. 3 ref. D);
- fix it with the two supplied screws (fig. 3 ref. E);
- fix 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.
- close the box and secure it with the 4 screws (fig. 3 ref. F);
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 specified on the appliance
plate data) (230Vac +/-15%, 50Hz);
• The power line is equipped with an effective earth connection and is correctly
sized for maximum 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 exerted is about 4N) (see
fig.3 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 (fig. 4 ref. A):
• pass the probe through the hole on the shoulder (fig. 4 ref. B)
• insert the probe in the lower hole (fig. 4 ref. C)
• fix the probe in the special hook (fig. 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 (fig. 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 2x0.5 mm and maximum length 20 m (keep this connection

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.
• 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.
Each time a key is pressed, the letters "BL" appear for a few seconds
on the display. To select a function, the control block must be removed.
• Remote control via thermostat B0736 (optional kit):
To enable communication with thermostat B0736, hold down
keys - and
as described in the appropriate section. If the function is active, each
time a key is pressed, the letters "re" appear for a few seconds on the
). display.

To select a function, the "remote control" must be disabled.
N.B.:
- When the connection is active, the remote control is disabled.
- The flap cannot be controlled using the remote control.
2.7.1 CONNECTION WITH WIRED CONTROLLER B0736
• Move the connector on connection X8 to connector X7.
the CP window contact will be controlled from the wall-mounted
control B0736
• Connect the cables from connection AB of the B0736 controller to
connector AB on the control (being careful to observe the polarity, see
fig.19) ending the furthest unit with the 120 Ohm resistance.
• Enable the connection by pressing keys
To disable the connection press keys
• The commands
display will show the wording "rE" each time they are activated.
• The indicators
fan speed set.
• For the functions and settings see the instructions for the B0736 controller.
Once the connection and any configuration operations are complete, close
the electrical panel again (fig.3 ref.C) using the screws removed previously.
Refit the front panel back fig.2 making sure to connect the display connector.
Secure the front panel with the 2 screws fig.1. The machine can now be
. powered up.

2.8 CLOSING THE APPLIANCE
• Mount the aesthetic side panel on the ventil radiator/fan coil;
• tighten the top screw fastening the side panel (fig. 1 ref. L or ref. F);
• refit the air outlet safety grill (fig. 1 ref. A).
• Position the screw cap provided in the housing on the control panel (fig. 1 ref. H).
