The VMF-E1 kit is composed of:
• E18 thermostat board inserted in a protec-
tive case, easily applicable to the fancoil
side.
The E1 thermostat board is complete with
protection fuse, dip-switch for configura-
tion and connectors for connection with:
• electric power supply,
• earth connection,
• valve control,
• Inverter control module power supply,
• room air temperature probe,
• water temperature probe,
• auxiliary water temperature probe,
• control panel (user interface),
• occupancy sensor,
• external contact,
• microswitch contact connected to fancoil
louver (if provided),
• system central supervisor (VMF-E5) system
serial device,
• fan coils network serial device (TTL).
VMF-E1 allows you to manage:
• The three fan speeds manually.
• Continuous and thermostated ventilation
through valve controls.
• Fan automatic mode with BRUSHLESS
motor 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 chan-
geover function.
• One additional water probe to control the
second coil (4-pipe systems).
• Season changeover based on water or air
temperature (for 4-pipe systems).
• Input for “external contact”. This is a digital
input with the following logic:
- “Open” the thermostat operates normally;
- “Closed” the fancoil is switched off.
• Microswitch for louver contact.
• Anti-freeze function.
• Occupancy sensor to enable the “SLEEP”
function from external contact (ambient
set-point reduction by 2 or 5 degrees,
depending on settings, in case of room not
occupied).
• Input for local serial device. The E18 ther-
mostat was designed to communicate
with other E0 and/or E1 and/or E18 type
thermostats, through a dedicated serial
connection based on TTL logic standards.
The above serial communication is essen-
tial for the exchange of information within
small fancoil networks (up to a max of 6
thermostats and with max length of about
30 metres). This was conceived to satisfy
the small areas with multiple fancoils that,
however, are to be controlled from a single
control point. Specifically in this network
there is always a master to which the user
interface is connected (VMF-E2, VMF-E4),
which controls the operation of the slaves
connected to it, based on the settings made
on its user interface.
• Supervision serial connection input. In the
networks composed of more fancoils divi-
ded into independent climate zones, the
VMF-E18 zone regulator allows communi-
cation with a system central supervision
device (VMF-E5).
Compatible accessories:
- Refer to the VMF System documentation
The VMF-E18 accessory is an evolved electronic thermostat kit to be applied on inverter fan coils; it requires an interface inside the fancoil (VMF-E2)
or on the wall (VMF-E4; VMF-E4D).

VMF-E18
TTL NETWORK
• It consists of a max of 6 fan coils (one Master
and 5 Slave)
• Max length of TTL line 30m.
The Master fan coils are equipped with control
panel and electronic board with microprocessor,
equipped with outputs for insertion in a TTL
network.
The Slave fan coils are equipped with electronic
board with microprocessor (accessory VMF-E18,
VMF-E1 or VMF-E0), equipped with outputs for
insertion in a TTL network.
All TTL network fan coils must have the same type
of accessories.
The settings (set-point) of the panel on the fancoil
(master) are recognised by the other fan coils
(slave).
The units connected to the TTL network are auto-
matically recognised, they do not require any
configuration.
