GENERAL INfORMATION

• versions without microprocessor
controller:
With or without water valve.
Versions without microprocessor con-
troller need to be combined with a
control panel (accessory) chosen from
standard control panels (compatible
with the configuration of the fan coil
unit) or be combined with a thermo-
stat from the VMF system.
warning! The VMF (VMF-E0 / VMF-E1)
thermostat can not be installed inside
the fan coil unit but the installer must
provide an adequate housing close to
the fan coil unit (such as a recessed
electrical box on the wall behind the
fan).
vMf (variable Multi flow System)
Management and control system of
hydronic systems for the air-condi-
tioning, heating and production of
domestic hot water.
The VMF system allows complete
control of every component of a
hydronic system both locally and
c e n t ra l l y a n d , c o m m u n i c a t i n g
between the various components of
the system, manages the performance
without ever neglecting the end user's
request of comfort, but reaching it as
efficiently as possible with energy
saving.
If you add the advantages deriving
from such an innovative control to
the flexibility of a hydronic system,
you get a more efficient and effective
alternative to the variable refrigerant
flow systems (VRF).
The VMF system is extremely flexible,
enough to allow various steps of con-
trol and management, expandable at
different moments:
1) Control of a single fan coil
unit.
2) Control of a microzone (one
MASTER fan coil unit and a maxi-
mum of 5 SLAVE fan coils units).
3) Control of multi independent
zones system (one MASTER fan coil
unit and a maximum of 5 SLAVE fa
coil units for each zone).
4) Control of a fan coil unit sys-
tem, plus management of the heat
pump (if compatible with the VMF
system).
5) Control of a fan coil unit sys-
tem, heat pump and management of
the domestic hot water system (VMF-
ACS).
6) Control of a fan coil unit sys-
tem, heat pump, domestic hot water
production and additional 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 pro-
duction, additional circulators and
management of heat recovery units,
maximum 3, (with the ability to han-
dle up to 3 VMF-VOC sensors) or a
boiler.
• The VMF system can operate and
manage, through a VMF-E5N / VMF-
E5B panel, a maximum 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 control inter-
face; this interface can be mounted
on the fan coil unit (only for the mod-
els (where it is possible) or be mount-
ed 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 temper-
ature 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 con-
troller:
With or without water valve.
Versions with microprocessor control-
ler have a display on the front panel
showing the main functions of the
unit.
The versions with microprocessor con-
troller need to be combined with one
of the two available control systems
(accessories PFW2 or TLW2) provided
as required as a necessary accessory
for the unit operation allowing turn-
ing on, turning off and all the fan
coil unit control and programming
operations.
The two control systems cannot be
used at the same time on the same
fan coil unit.
The control system checks all the func-
tioning parameters and carries out all
the operations necessary to enable
the required room conditions to be
maintained.
The control system also provides some
automatic functions to increase com-
fort and make the most frequently
repeated operations 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 out-
age the FCW unit starts again auto-
matically with the same settings that
it had at the time of stopping (with
the exception of the Timer and Sleep
settings).
