ACCESSORIES
The thermostat is used to control:
The GLL_N accessory consists of :
WARNING: Not all functions can be
operated simultaneously, see the docu-
mentation of the accessory
• Three fan coil speeds in manual mode
• Continuous and thermostat-controlled
ventilation via valve control
• Season visualisation
• Visualisation of alarms and ventilation
request
• Up to two ON/OFF 2- or 3-way valves
• The switch-on of an electric heater
• An air temperature probe
• A water temperature probe, with mini-
mum and maximum temperature and
changeover functions
• An additional water probe for control-
ling the second coil (4-pipe systems)
• Season change according to the water
or air temperature (4-pipe systems)
• Input for “external contact”. This is a
digital input with the following logic:
- When open, the thermostat works nor-
mally;
- When closed, the fan coil is switched
off.
• Anti-freeze function
• Presence sensor to enable the “SLEEP”
function from an external contact
(reduction of ambient set-point by 2 or
5 degrees, depending on the settings, if
a room is unoccupied)
• Input for local serial. The thermostat is
designed to communicate with other
GLLI-N and/or GLL-N and/or VMF-
E18 and/or VMF-E1 and/or VMF-E0
type thermostats via a dedicated serial
based on the TTL logic standards. This
serial communication is essential for
the exchange of information within
small fan coil networks (up to 6 ther-
mostats and with a maximum length of
30 metres.) It was designed, in fact, for
small areas where the fan coils (more
than one) need to be controlled from
a single control point. More specifi-
cally, this network always contains a
Master (to which a user interface VMF-
E2, VMF-E4 / VMF-E4D is connected)
which controls the operation of the
Slaves connected to it, according to the
settings made on its user interface.
• Input for supervision serial. In networks
made up of several fan coils subdivided
into independent temperature areas,
the GLL-N (with VMF-E4 / VMF-E4D)
area thermostat allows communication
with a VMF-E5B / VMF-E5N central sys-
tem supervisor.
GLL10N - GLL20N INTAKE AND DELIVERY GRILLE UNIT WITH "VMF System" THERMOSTAT
• Intake and delivery grille unit
• "VMF System" advanced electronic
thermostat board, installed in the
electric box, easily applicable to the
fan coil.
The thermostat board has a protective
fuse, a dip-switch for configuration,
and connectors for connection with:
- the power supply,
- the earthing,
- the valve control,
- fan motor supply,
- the ambient air temperature probe,
- the water temperature probe,
- the auxiliary water temperature probe,
- the control panel (user interface),
- the presence sensor,
- the external contact,
-
the VMF-E5B / VMF-E5N central supervisor
system serial,
- the fan coil network serial (TTL).
GLL10N (600x600)
GLL20N (840x840)
Intake and delivery grille unit with "VMF System" advanced electronic
thermostat (obligatory accessory).
The form and opening of the suction louvres were developed in order
to have the best possible distribution of the air, both when functioning
in winter as well as in summer.
Suction occurs through the central grille, and delivery through the
manually adjustable, perimetric slots. In plastic, colour RAL 9010, it
contains the air filter that can be easily removed for cleaning.
The GLL_N includes the electric box with incorporated VMF System
thermostat board, with bayonet coupling to the connector bound to
the unit load-bearing structure.
The GLLI_N needs to be interfaced with a VMF-E4 / VMF-E4D external
control panel if installed on a single FCL unit, or with a "Master"
function in a network with up to 5 other "Slave" fan coils supplied
with "VMF System" thermostat only (GLLI-N and/or GLL-N and/or
VMF-E18 and/or VMF-E1 and/or VMF-E0).
If GLL_N is combined with a VMF-E4 / VMF-E4D control panel
("Master" confi guration), the fan coil can be connected to a VMF-E5B /
VMF-E5N central supervisor system.
