Vmf System Glossary - AERMEC VMF-E5 Manuel D'utilisation

Term Meaning
IT IS an abbreviation which stands for Variable Multi Flow, and indicates air conditioning systems based on a chiller to which
VMF
several fan coils are connected, supplied by a variable water flow whose value depends on the actual power demand by the
system.
Inside of a VMF system, fan coils not supplied with controls are defined as SLAVE; therefore SLAVE fan coils must be
SLAVE
connected to other units (called MASTER) which can control the fan coils via a serial connection.
Inside of a VMF system, fan coils supplied with controls are defined as MASTER (on board the machine or on a wall panel);
MASTER
these units can control up to 5 SLAVE units,via a serial connection, which will automatically reproduce all the settings which
the user sets for the MASTER units.
VMF - E0
Simplified thermostat accessory; this device makes it possible to use a fan coil unit VMF system as a SLAVE unit.
VMF-E1
Thermostat accessory; this device makes it possible to use a fan coil unit VMF system as a MASTER/SLAVE unit.
Thermostat accessory; this device makes it possible to use a fan coil unit VMF system as a MASTER/SLAVE unit, for units
VMF-E18
with inverter motors.
VMF-E2
Control interface to be coupled to a thermostat accessory to be mounted on a fan coil; this accessory has been designed to
be mounted on MASTER units (for combination with various fan coil models, refer to the documentation of the accessory).
VMF-E2H
Control interface to be coupled to a thermostat accessory to be mounted on the wall; this accessory has been designed for
VMF - E4
connection to MASTER units.
VMF-E5
Advanced panel for centralised management of an entire VMF system.
Electrical control board accessory required for management of components used in the system for production of domestic
VMF-DHW
hot water (temperature probes to be inserted in a DHW storage tank, three-way diverter valves, pumps etc.).
VMF-VOC
Accessory probe for detection of air quality.
VMF-CRP
Accessory to manage a boiler, recovery units or pumps.
Interface cards that allow to connect several fan coils in a network controlled by a unique centralised control panel (switch
VMF - SIT3
or thermostat).
Water probe to be used in replacement of the one supplied as per standard with VMF-E0/E1/E18 thermostats to control
VMF-SW
the maximum cold range.
VMF-SW1
Extra water probe to be used for 4-pipe systems with VMF-E1/E18 thermostats to control the maximum cold range.
The ZONE bus represents connections to be implemented between the various SLAVE fan coils and relative MASTER fan coil
ZONE bus
(each zone can contain 6 fan coils at most, of which 5 SLAVE and one MASTER).
SYSTEM bus
The SYSTEM bus represents the connections to be implemented between MASTER units and the rest of the system.
