5 SLAVE fa coil units for each zone).
4) Control of a fan coil unit system, plus man-
agement of the heat pump (if compatible
with the VMF system).
5) Control of a fan coil unit system, heat pump
and management of the domestic hot water
system (VMF-ACS).
6) Control of a fan coil unit system, heat pump,
domestic hot water production and addition-
al circulators (up to a maximum of 12 using
three additional VMF-CRP modules).
7) Control of a fan coil unit system, heat pump,
domestic hot water production, additional
circulators and management of heat recovery
units, maximum 3, (with the ability to handle
up to 3 VMF-VOC sensors) or a boiler.
• The VMF system can operate and manage,
through a VMF-E5N / VMF-E5B panel, a maxi-
mum of 64 zones consisting of a MASTER fan
coil unit and a maximum of 5 SLAVE fan coil
units connected to each MASTER, for a total
of 384 fan coil units.
• Besides the central control supplied by the
VMF-E5N / VMF-E5B panel, the MASTER fan
coil units must be provided with a local con-
trol interface; this interface can be mounted
IMPORTANT INFORMATION
WARNING: The fan coil unit is connected to the power supply
and a water circuit. Operations performed by persons without
the required technical skills can lead to personal injury to the
operator or damage to the unit and surrounding objects.
The unit shall be installed in accordance with National Wiring
Regulations."
MALFUNCTION
In the case of a malfunction remove power to the unit then
reapply it and start the unit again. If the problem occurs again,
call your area After-Sales service department promptly.
POWER THE FAN COIL UNIT ONLY WITH 230 VOLT, SINGLE
PHASE, 50 Hz
Use of other power supplies could cause permanent damage to
the fan coil unit.
USE THE (TLW2) REMOTE CONTROL OR THE WIRED CON-
TROL PANEL (PFW2) TO TURN THE FAN COIL UNIT ON AND
OFF
Do not turn the fan coil unit on or off using the auxiliary switch
except in an emergency.
DO NOT PULL THE ELECTRICAL CABLE
It is very dangerous to pull, tread on or crush the electrical
power cable or fix it with nails or drawing pins.
A damaged power cable can cause short circuits and personal
injury.
DO NOT PUT ANYTHING IN THE AIR OUTLETS
Do not put anything at all in the air outlet slots.
This could cause injury to people and damage to the fan.
DO NOT USE THE FAN COIL UNIT IMPROPERLY
Do not use the fan coil unit in animal husbandry applications.
VENTILATING THE ROOM
Periodically air the room in which the fan coil unit has been
installed; this is particularly important if the room is occupied
by many people, or if gas appliances or sources of odours are
on the fan coil unit (only for the models
(where it is possible) or be mounted into a
wall panel (VMF-E4 / VMF-E4D).
• Different functions can be controlled through
the VMF-E5N / VMF-E5B panel, including:
- Identify the different zones giving a name for
each one.
- Check and set the ON-OFF function and the
set point temperature of each zone.
- Set and manage the set point temperature of
the heat pump.
- Scheduling time clocks.
• Simple installation of the fan coil unit system
through the SELF-MONITORING function of
the MASTER fan coil units.
• Versions with microprocessor controller:
With or without water valve.
Versions with microprocessor controller have a
display on the front panel showing the main
functions of the unit.
The versions with microprocessor controller
need to be combined with one of the two
available control systems (accessories PFW2
or TLW2) provided as required as a neces-
sary accessory for the unit operation allowing
present.
CORRECTLY CONTROLLING THE TEMPERATURE
The room temperature should be controlled in order to provide
maximum comfort to the people in the room, especially if they
are elderly, children or ill, avoiding sudden changes in tempera-
ture between the outside and inside above 7 °C in summer.
Careful choice of the room temperature will lead to energy sav-
ings.
CORRECTLY ADJUSTING THE AIR JET
The air coming out of the fan coil unit must not strike people
directly; in fact, even if at a temperature that is higher than the
room temperature, it could cause a cold sensation and resulting
discomfort.
Only adjust the vertical blades by hand.
In the versions with microprocessor controller adjust the hori-
zontal blade with the LOUVRE or SWING key of the remote con-
trol or the wired control panel.
In the versions without microprocessor controller adjust the
horizontal blades by hand.

DURING OPERATION

Always leave the filter in the fan coil unit during operation oth-
erwise dust in the air will dirty the surfaces of the coil.
WHAT IS NORMAL
During cooling, water vapour may be present in the air dis-
charge.
During heating it might be possible to hear a slight hiss around
the fan coil unit. Sometimes the fan coil unit might give off
unpleasant smells due to the accumulation of substances from
the air of the room (especially if the room is not ventilated regu-
larly. Clean the filter more often).
During operation, there could be noises and creaks inside the
device, due to the thermal expansion of the various compo-
nents (plastic and metallic), but this does not indicate a mal-
function and does not cause damage to the unit unless the
maximum input water temperature is exceeded.
turning on, turning off and all the fan coil
unit control and programming operations.
The two control systems can be used at the
same time on the same fan coil unit.
The control system checks all the functioning
parameters and carries out all the operations
necessary to enable the required room condi-
tions to be maintained.
The control system also provides some auto-
matic functions to increase comfort and
make the most frequently repeated opera-
tions easier:
- Minimum temperature sensor; in order to
avoid cold air blasts in the winter mode,
allowing ventilation only if the water in the
system is hot.
- Auto Restart mode, after a power outage the
FCW unit starts again automatically with the
same settings that it had at the time of stop-
ping (with the exception of the Timer and
Sleep settings).
