HOW TO USE THIS MANUAL
This manual is intended to provide a complete support for installation of VMF systems. These systems are made up of several
elements which, once installed correctly, must communicate one with another forming a network of devices which will work
automatically.
VMF systems can differ by number and type of elements making up an air conditioning system. This documentation has been
drawn up analysing in detail an example of a system which uses all the accessories managed by the VMF system.
THE INFORMATION PROVIDED IN THIS MANUAL IS DEDICATED TO VMF SYSTEM INSTALLERS. WE RECOMMEND
PAYING THE UTMOST ATTENTION WHILE PERFORMING THE ELECTRICAL CONNECTIONS OF THE COMPONENTS
AND SETTING THE SYSTEM SOFTWARE AS INCORRECT OPERATIONS COULD DAMAGE THE SYSTEM.

Sequence of operations to be performed to install the various components:
(1) Install the selected heat pump; the unit must be appropriately installed electrically and hydraulically according
to that described in the system design. The heat pump is connected to the MODBUS serial line by means of the
MODU-485A accessory (see the relevant documentation to install this accessory).
(2) Install the system storage tank; the system storage tank must be installed according to standards in force,
making sure all the components required for its correct use are supplied (loading unit, pressure gauge, safety
valves, etc...).
(3) Install the DHW storage tank; the DHW storage tank must also be installed according to standards in force,
making sure all the components required for its correct use are supplied (loading unit, pressure gauge, safety
valves, etc...); remember to pay the utmost attention when selecting the supplementary electric resistance, the
size of which is linked to the dimension of the tank itself (the supplementary resistance will also affect the type of
electric control board to be purchased).
(4) Install the supplementary electric resistance for DHW storage tank; the DHW storage tank must be provided
with a 3kW single-phase supplementary electric resistance with relative safety thermostat, to be used in some
phases of domestic hot water production (for example during the anti-legionella cycle). The resistance must be
installed on the storage tank, According to the procedures indicated on the relevant documentation; the resistance
power supply must be connected to the specific terminals on the VMF-ACS3KTM accessory (as indicated in the
VMF-ACS board installation procedure).
(5) Install the 3-way diverter valve; this valve allows the VMF system to divert water from the air-conditioning
system to the DHW storage tank; this valve must be installed on the heat pump flow line, upstream the storage
tanks (as highlighted in the VMF system hydraulic diagram) connecting it to the VMF-ACS3KTM control board (as
indicated in the VMF-ACS control board installation procedure, provided further on).
(6) Install the VMF-ACS3KTM accessory; this accessory allows to manage the loads involved in domestic hot
water production, based on the intended type of system; in the proposed example the accessory will manage:
- The probe inserted in the system storage tank;
- The probe inserted in the DHW storage tank;
- The 3-way diverter valve;
- The electric resistance (3kW single-phase) inserted in the DHW storage tank.
To install the VMF-ACS electric control board, refer to the specific documentation.
(7) Install the VMF-CRP expansion board (1); this expansion board manages different types of loads; in this case
it will manage the heat recovery unit and the VMF-VOC accessory.
(8) Install the VMF-CRP expansion board (2); this expansion board manages different types of loads; in this
case it will manage the 4 zone pumps. The installation of the two VMF-CRP expansion boards requires appropriate
positioning in a specific electric box inside the technical room. The electric box, the fixing brackets, the transformer
powering the VMF-CRP modules and all the protective elements necessary are not supplied. For further information
concerning assembly of the VMF-CRP modules, refer to the specific documentation.
(9) Install a collector with relative zone pumps; this element allows to manage the hydraulic lines and the pumps
of each individual zone from a point located in the technical room, as indicated in the standard hydraulic diagram
in the chapter “Hydraulic diagram of VMF system”.
(10) Install the heat recovery unit; the UR unit provides an air exchange in the various rooms. For further
information concerning assembly of the heat recovery unit, refer to the specific documentation.
(11) Install the VMF-VOC probe; the accessory VMF-VOC probe detects air quality and therefore pilots a
heat recovery unit. For further information concerning assembly of the heat recovery unit, refer to the specific
documentation.

The figure to the left indicates which rooms make up zone A; the master unit
installed in this zone is identified on VMF-E5 by the label “NIGHT A”.
In this case, the zone is served by one unit alone, and it is therefore
managed as master. The type of unit chosen obliges the installer to use the
VMF-E18 thermostat as it is an inverter fan coil.
FCXI P (1)
VMF-E18 (2)
VMF-E4 (3)
Material for ZONE A
An FCXI-P series unit has been selected in this zone to meet requests; by making a

GB
6795773_01
Sequence of operations to be performed to install the various components:
(1) Install the FCXI-P fan coil: this unit is the only fan coil of the zone (MASTER). The unit must be appropriately
installed electrically and hydraulically following the instructions provided in the fan coil documentation; the duct
must be properly sized based on the features of the fan coil.
(2) Install the VMF-E18 thermostat: to manage the INVERTER fan coil via a VMF network, a VMF-E18 thermostat

proposed example, the interface is represented by a VMF-E4), and to connect the thermostat to the VMF system
serial network (for detailed information on installation and connection of the VMF-E18 thermostat, refer to the
specific documentation). The following is a summary of the operations required for installation of the proposed
example:
(a) remove the service terminal board from the side of the fan coil;
(b) mount the box of the VMF-E18 thermostat in place of the service terminal board;
(c) using the connection cables previously detached from the terminal board, connect the thermostat with the

chapter VMF NETWORKS SERIAL CONNECTIONS).
ATTENTION: the VMF-E18 thermostat boards have dip switches which MUST be set correctly based on the
features of the fan coil to which the thermostat is connected. Refer to the thermostat documentation to set
these dip switches correctly.
(3) Install the wall-mounted VMF-E4 panel: to manage the FCXI-P fan coil directly from the room of Zone A, the

summary of the operations required for installation of the proposed example:
(a) remove the service terminal board from the side of the fan coil;
(b) mount the box of the VMF-E0 thermostat in place of the service terminal board;
(c) using the connection cables previously detached from the terminal board, connect the thermostat with the
electric motor controls (we recommend referring to the wiring diagrams of the unit to perform this connection);
(d) connect the power supply to the VMF-E0 thermostat;
(e) connect the air probe to the VMF-E0 thermostat (the air probe is indicated as SA in the wiring diagrams);
(f) connect the water probe to the VMF-E0 thermostat (the water probe is indicated as SW in the wiring diagrams);
(g) connect the VMF-E0 thermostat to the VMF-E1 thermostat of the master unit (via TTL zone network).
ATTENTION: the VMF-E0 thermostat boards have a dip switch which MUST be set correctly based on the
features of the system to which the thermostat is connected; refer to the thermostat documentation to set
this dip switch correctly.

VMF system - Implement zone
E
The figure to the left indicates which rooms make up zone E; the master unit
installed in this zone is identified on VMF-E5 by the label “Day”.
In this case, the zone is served by three units (one master and two slaves);
the type of unit chosen obliges the installer to use the VMF-E1 thermostat for
the master and two VMF-E0 for the slaves.

Material for ZONE E
Three OMNIA HL units have been selected in this zone to meet requests; the master
unit will be piloted by installation of a VMF-E2H control interface.
The material required to implement this zone is:
VMF-E5 (8)
VMF-E1 (2)
Omnia HL (4)
Omnia HL (1)
VMF-E0 (5)
VMF-E2H (3)
