DESCRIPTION OF THE UNIT
PURPOSE OF THE MACHINE
The LFC fan coil unit is a terminal for the treatment of air in
winter and in summer.
The LFC fan coil unit has been designed to be incorporated
into channelled systems and can be tailored to suit any
system thanks to its wide range of accessories.
AVAILABLE VERSIONS AND SIZES
fan coil units in the LFC series are available in:
2 sizes with 4-row battery
LFC1240
2 sizes with 4- + 1 row battery
LFC1241
2 sizes with 4-row battery with housing for candle-type
electric resistor (not supplied)
LFC1241R
2 sizes with 5-row battery
LFC1250
TECHNICAL CHARACTERISTICS:
Terminal for air treatment for horizontal installation consisting of a
fan unit and a battery for cooling or heating, for systems with two or
four pipes as well as the possibility of combining electrical resistors
for heating.
LFC has been designed to give easy access to the components and
consequently the installation and maintenance will be made sim-
plier.
LFC can be tailored with a wide range of accessories to suit the
most disparate system requirements, flanges and plenum chambers
are available to connect the terminal to intake and deliver channels
whether straight or "crooked".
LFC fan coil units can be combined with control panels with speed
connectors or electronic thermostats (accessories). To connect an
electronic thermostat to the LFC fan coil units a SIT interface card
must be used.
A single control panel can be used for several fan coils providing an
interface card is installed for each fan coil.
It is possible to have different residual heads for any channelling
thanks to the five-speed fan motor; with control panels with three-
speed selector it is possible to select the three most frequently used
(connections available on the terminal block).
Reversible four/ and five-row batteries with corrugated fins (two-
pipe version) and four + 1 row (systems with four pipes), with possi-
bility of additional batteries and electrical resistors in addition to a
wide range of other accessories.
The free access to the base unit must be prevented by means of
suitable devices such as protection meshes or grilles, in conformity
with UNI EN 294.
CUSTOMISATIONS (ACCESSORIES):
OBLIGATORY ACCESSORIES:
The LFC terminals in some types of installation may be compulso-
rily linked to dedicated accessories.
BCL 10 - Integral foam polyurethane drip pan for the collection of
condensate, that can be inspected from underneath, covers both the
battery and the plumbing connections.
Obligatory accessory for cold operation and in conjunction with
the VCL valves.
CA - INTAKE CASING
The intake casing makes it possible to close of the ventilation
assembly in a casing. It is made of galvanised sheet steel. It has
brackets for ceiling mounting.
An obligator accessory in combination with the FA1200 intake flange
CA4 - INTAKE CASING WITH HIGH-EFFICIENCY FILTER
The intake casing makes it possible to close of the ventilation
assembly in a casing. It is made of galvanised sheet steel. It has
brackets for ceiling mounting.
G4 class filter in accordance with standard EN779.
An obligator accessory in combination with the FA1200 intake flange
SIT - Interface card for connecting the electronic control panels to
the LFC fan coils is applied in the electrical fan coil box. A single
control panel can be used for several fan coils providing an interfa-
ce card is installed for each fan coil.
Obligatory accessory in conjunction with the electronic thermostats.

ACCESSORIES:
FA1200 - INTAKE FLANGE WITH FITTINGS
The intake flange is fitted with circular cross section fittings 225
mm in diameter made of galvanised sheet steel.
Accessory to be combined with CA / CA4.
PA1200 - REVERSIBLE INTAKE PLENUM
Reversible intake plenum (lengthwise and orthoganal intake) with
circular section fittings 225 mm in diameter, made of galvanised
sheet steel.
PM1200 - REVERSIBLE DELIVERY PLENUM
Reversible intake plenum (lengthwise and orthogonal intake) with
circular section fittings 225 mm in diameter, made of galvanised
sheet steel and insulated internally.
PX2 CONTROL PANEL
Control panel to be fitted on the wall, consisting of on/off selector
switch and three-position selector switch to select fan speed.
FMT10 - ELECTRONIC CONTROL PANEL
Electronic thermostat for fan coils; can be connected to On/Off val-
ves for closing coil water supply. Simplified controls with only 2
selectors for adjusting temperature and fan speed (3 speeds). Air
temperature sensor included. Recessed installation.
FMT20 - ELECTRONIC CONTROL PANEL
Electronic thermostat with LCD for fan coils; can be connected to
On/Off valves for closing coil water supply. Simplified controls with
only 2 selectors for adjusting temperature and fan speed (3 speeds).
Air temperature sensor included. Recessed installation.
PXA E - ELECTRONIC MULTIFUNCTION CONTROL PANEL
Electronic thermostat for fan coils installed in two-pipe or four-pipe
systems.
Simplified commands with two selectors for temperature and venti-
lation control (three speeds with manual or automatic control). It
can control two valves of the On-Off type. Wall mounting.
PXA R - ELECTRONIC MULTIFUNCTION CONTROL PANEL
Electronic thermostat for fan coils installed in two-pipe systems, and
systems with two pipes with electric heater or four pipes (without
electric heater).
Simplified controls with just two selectors for the control of the tem-
perature and the ventilation (3 speeds with manual or automatic
control). The control of the electric heater can be activated using
the speed selector. It can monitor the electric heater and one On-
Off type valve or two On-Off type valves.Water temperature sen-
sor included. Wall mounting or mounting on the fan coil.
RX 1200 - Armoured 3000 W electrical resistor with steel fins that
can be installed in all the configurations (4 rows, 5 rows, 4+1
rows). It is fitted with a double thermostat, the first to automatically
rearm and the second to manually rearm.
SIT5 - THERMOSTAT INTERFACE CARD
They allow to set up a fancoils network (max. 10) commanded by a
centralised panel (switch or thermostat).
SIT5: commands the 3 fan speeds and two valves (four-pipe
system); it sends the thermostat commands to the fancoils network
on each which the SIT accessory must be installed.
SW3 MINIMUM WATER TEMPERATURE SENSOR
The SW3 accessory for PXA E and PXA R is a detector sensor for the
temperature of the water inside the heating battery to prevent the
fans from working when the water temperature is less than 39°C. The
SW3 sensors are arranged for 230V single phase power supply.
VCL 1 - Thee-way, four-connection valve or 4- or 5-row main battery.
VCL 2 - Thee-way, four-connection valve for 1--row heating battery.
WMT05 - ELECTRONIC CONTROL PANEL
Electronic thermostat for fan coils installed in 2-pipe systems.
Wall installation.
WMT10 - ELECTRONIC CONTROL PANEL
Electronic thermostat for fan coils, can be connected to On/Off val-
ves for closing coil water supply.
The panel is electrically protected by an internal fuse. The
tion system is selected by applying jumpers during installa-
tion. Wall installation.
