• 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

centrally and, communicating

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).
