VMFE0 ELECTRONIC THERMOSTAT FOR FAN COILS
Every thermostat applied to a VES
series unit must feature a VMF-SIT3
board.
The VMF-E0 accessory is an evolved
electronic thermostat kit to be applied
to fan coils; it requires an interface on the
wall (VMF-E4).
The VMF-E0 thermostat must be applied to
the side of the fan coil.
VMF-E0 allows you to manage:
• E0 thermostat board inserted in a
protective case, easily applicable to the
fan coil side. The E0 thermostat board
is complete with protection fuse, dip-
switch for configuration and connectors
for connection with:
- electric power supply,
- earth connection,
- valve control,
- motorised fan control,
- ambient air temperature probe,
- water temperature probe,
- control panel (user interface),
- external contact,
- fan coils network serial device (TTL).
• Three fan manually-operated speeds.
• Continuous and thermostated ventila-
tion through valve control.
• Fan automatic mode based on the load.
• Season display.
• Alarms and ventilation request display.
• Up to two 2-way or 3-way ON/OFF valves.
• One electric heater activation.
• Germicidal lamp.
• Plasmacluster filter.
• One air temperature probe.
• One water temperature probe with mini-
mum and maximum temperature and
changeover function.
• Season changeover based on water or air
temperature (for 4-pipe systems).
• Input for “external contact”. This is a digi-
tal input with the following logic: when
open the thermostat operates normally,
when closed the fan coil is switched off.
• Microswitch for louver contact.
• Anti-freeze function.
• Communication with other thermostats
through a dedicated serial connection
based on TTL logic standards.
ATTENTION!: Not all the functions of the accessory can be applied to the unit. Check the compatibility of the functions with the
configuration of the unit and of the other accessories applied. For complete information relating to the functions please refer to the
technical manual of the unit and accessories.
ACCESSORIES
VMF - VARIABLE MULTI FLOW SYSTEM
• VMF: Variable Multi Flow System
Hydronic system management and
control unit for air conditioning, heating
and domestic hot water production.
T h e VMF s ys t e m e n s u r e s t h e
complete control of every single
component of a hydronic system,
both local and centralised, through
communication between the various
system components, managing the
performance without neglec ting
the end user's request for comfort at
any time, but reaching it as efficiently
as possible, with consequent energy
savings.
Summing up the advantages of a such
an innovative control with the flexibility
of a hydronic system, you achieve a
more effective and efficient alternative
to variable refrigerant volume (VRF)
systems.
The VMF system is extremely flexible,
to the extent that it offers various
control and management steps, also
expandable at different times:
1) Control of a single fan coil.
2) Control of a micro-zone (one MASTER
fan coil and up to 5 SLAVE fan coils).
3) Control of a network consisting
of several independent zones (one
MASTER fan coil and up to 5 SLAVE fan
coils per each zone).
4) Control of a fan coil network, plus heat
pump management (if compatible with
the VMF system).
5) Control of a fan coil network, of the
heat pump and management of the
domestic hot water system (VMF-ACS).
6) Control of a fan coil network, heat
pump, domestic hot water production
and additional pumps (up to 12 using 3
additional VMF-CRP modules).
7) Control of a fan coil network, heat
pump, domestic hot water production,
additional pumps and management of
heat recovery unit, up to 3, (with the
possibility of managing up to 3 VMF-
VOC probes) or a boiler.
• The VMF system can control and
manage, via a VMF-E5 panel, up to 64
zones, consisting of a MASTER fan coil
and up to 5 SLAVE fan coils connected to
each MASTER, for a total of 384 fan coils
• In addition to the centralised control
provided by the VMF-E5 panel, the
MASTER fan coils must be equipped
with a local control interface; this
interface can be mounted on board the
fan coil (VMF-E2 / VMF-E2H) or on a wall
panel (VMF-E4)
• Via panel VMF-E5 it is possible to control
several functions, among which:
- Identify the various zones by giving
each one a name that characterises it
- Control and set the ON-OFF function
and the temperature setting of each
zone
- Set and manage the temperature
setting of the heat pump
- Time slot programming
• Simple installation of the fan coil
network thanks to the SELF-DETECTION
function of the MASTER fan coils
The VMF-E0 kit is composed of:
