CONTENTS

WARNING: The suction and delivery

English

grille GLLIN is an accessory that must be connected to the electronic cards applied to fan coils. Consult the manuals of the fan coils and cards (if they have been provided as an accessory), and apply all safety precautions indicated for the electronic cards.

WARNING: the fan coil is connected

to the power supply and water circuit. Operations performed by unqualified personnel can lead to personal injury to the operator or damage to the unit and surrounding objects.

WARNING Components sensitive to static electricity may be destroyed by voltages notably lower than those at the human perception threshold. These voltages form when you touch a component or electric contact of a unit, without first discharging accumulated static electricity from your body. The damage caused to the unit by an overvoltage is not immediately evident

- it only appears after a certain period of operation.

STATIC ELECTRICITY

ACCUMULATION

Any person not connected in a conduc-

tive manner with the electronic potential of his surrounding environment can accumulate electrostatic charges.

STANDARD PROTECTION

AGAINST ELECTROSTATIC CHARGES

Earthing quality

When working with units sensitive to

electrostatic electricity, ensure that people, workplaces and unit casings are correctly earthed. This will prevent the formation of electrostatic charges.

Avoid direct contact

Only touch the element exposed to elec-

trostatic risk when absolutely essential (e.g. for maintenance).

Touch the element without coming into

contact with either the contact pins or the wire guides. If you follow this rule, the energy of the electrostatic charges cannot reach or damage the sensitive parts.

Before taking measurements on the unit,

it is necessary to discharge all elec-

trostatic charges from your body: to do this, just touch an earthed metal object. Only use earthed measuring instruments.

MALFUNCTIONING In the case of malfunctioning remove

the power to the unit then re-power it and start the apparatus up again. If the problem occurs again, call your areas After-Sales Service promptly.

DO NOT PULL THE WIRES

It is highly dangerous to pull, crush or

tread on the electric cables, or to fix them with nails or drawing pins.

A damaged power cable can cause short

circuits and injure people.

WARNING: Avoid any use of the device

by children or incompetent persons without appropriate supervision; also note that the unit should not be used by children as a toy.

DESCRIPTION

GLLI10N (600x600) GLLI20N (840x600) Intake and delivery grille unit with

"VMF System" advanced electronic

thermostat.

The grille is part of the GLLI-N range

grille unit (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.

GLLI_N needs to be interfaced with an

external control panel VMF-E4 (NOT SUPPLIED) if installed in a single "stand alone" FCLI unit or as a master unit of a fan coil slave network (max

5).If the GLLI_N is combined with a VMF-E4 control panel ("Master" configuration), the fan coil can be connected to a VMF-E5 central

supervisor system.

The FCLI units are available in two basic

sizes, called:

"Module 600" for units integrable in

standard 600x600mm suspended ceiling panelling

"Module 840" for the more powerful ver-

sions (to be housed in a compartment measuring 840x840mm).

SUCTION AND DELIVERY GRILLE

UNIT

(GLLIN range accessories)

The FCLI cassette-type fan coil is only

complete when used with a grille of the GLLIN range - an obligatory accessory for the operation of the fan coil with the VMF system. The grille accessories of the GLLIN range not only offer suction with a filter and air delivery fins, but also include a special electric box.

The form and opening of the delivery

fins were developed in order to have the best possible distribution of the air, both when functioning in winter as well as in summer.

Intake occurs through the central grille,

and delivery through the adjustable, outer slots. In plastic, colour RAL 9010, it contains the air filter that can be easily removed for cleaning.

FILTERING SECTION

The air filter is inserted in the suction

grille. Mechanical air filter with ABS frame. Filter in filtering class G1, self-

extinguishing class V0 (UL94). Easily removable and made from regen-

erable materials. May be cleaned by

washing.

VENTILATION CONTROL

Thermostat-controlled ventilation: The

choice of the regulation according to thermostatically controlled ventilation (dip3 OFF) foresees the switching off of the ventilation when the setpoint is reached. (See the dip switch settings table).

Position Operations

OFF

AUTO On reaching the setpoint, the ventilation proceedes with the minimum continuous speed.

Aux

The thermostat is off. It may however start again in Heating mode if the room temperature falls

below 7°C and the water temperature is suitable (anti-freeze function).

In this position, the minimum ventilation speed V1 is always active regardless of thermostat

requirements.

In this position, the average ventilation speed V2 is always active regardless of thermostat

requirements.

In this position, the maximum ventilation speed V3 is always active regardless of thermostat

requirements.

In this position, the minimum Aux ventilation speed is always active.

Continuous ventilation: The continuous ventilation is selected by means of dip3 that must be set to On. In practice the continuous ventilation provides ventilation even with thermostat fulfilled at the speed chosen. This function is disabled if the machine has no shut-off valve (dip1 OFF). In these particular cases, the ven-

tilation will always be managed with thermostatically controlled logic. The following table shows the ventilation speed activated depending on the position of the selector:

English

MINIMUM CONTINUOUS SPEED PARAMETERS

The "minimum continuous speed" is linked to the position of dip switch 8 (see paragraph on dip-switch settings) in the table below.

Position Continuous min. speed Cassette type

OFF

8% of the max inverter speed 600 x 600

12% of the max inverter speed 800 x 800

VALVE OPERATION

If a shut-off valve is present (dip1 ON), the position of the probe can be managed both upstream and downstream of the valve itself (in the standard position on the heat exchanger). The main difference between the two is in managing the ventilation in different ways. If the water

probe is upstream of the valve (dip2 ON) or is not present, a heat exchanger pre-heating function occurs and enables

the fan 2'40" after the first opening of the valve.

The valve in question (for the heat exchanger pre-heating function) is Y1 if this is a 2-pipe system (dip5 Off), whereas if it is a 4-pipe system it is Y2 (dip5 On). The inhibition time of the fan is then automatically calculated and depends on how long the valve remains closed; in

this way it could vary from a minimum of 0' 00" to a maximum of 2' 40". This ventilation enabling delay in relation to the opening of the valve is reset if the electric resistor is enabled, this is to ensure greater user safety. Refer to the specific table for the specific parameters of the dip switches.

AGLLI10/20NFJ 07/11_4528572_00

HOT/COLD MODE CHANGE OVER

WATER SIDE SEASON CHANGEOVER

English

If the thermostat is configured for use without a valve (dip1 OFF) or with a probe upstream of the valve (dip2 ON), then the water temperature detected is that available on the terminal, therefore the season is forced to Hot or Cold according to this temperature. The thresholds of the season changeover

are shown in the table below. In this configuration, the indications of the left LED correspond to the active mode. The ventilation is enabled only if the water temperature is suitable for the cooling mode or the heating mode. This allows on one side to avoid unwanted

cold ventilation in the winter season, and on the other side to check the turning on and off of all terminals, according to the actual condition of the water available (centralized control of the On-Off and Hot-Cold commands).

COLD SEASON CHANGEOVER

THRESHOLD 12 °C / 22°C 35 °C / 39 °C

22°C / 25°C 31 °C / 35°C Reduced band (dip 4 on)

VENTILATION ENABLING

The normal band (hot enabled at 39° C, cold enabled at 17° C) or the reduced band (hot enabled at 35° C, cold enabled at 22° C) is selected based on the (dip4).

SEASON CHANGEOVER BASED ON THE AIR

The season changeover of some systems is based on air temperature, these are:

- 2-pipe systems with the Water Probe downstream of the valve.

- All 2-pipe systems without water probe.

- All 4-pipe systems.

The season changeover occurs as follows:

- Cold mode: if the ambient temperature

detected is below the setpoint of an interval equal to the dead band (2° C or 5° C) it switches to the hot mode.

- Hot mode: if the ambient temperature

detected is above the setpoint of an interval equal to the dead band (2° C or 5° C) it switches to the cold mode.

HOT SEASON CHANGEOVER

THRESHOLD

DIP SWITCH

MEANING

Normal band (dip 4 off)

The dead band is decided through dip7 or rather if it has a dead band of 5° C (dip7 OFF) while if the dead band is 2° C (dip7 ON).

ANTI-FREEZE PROTECTION

The anti-freeze protection allows you to check that the room temperature never falls to freezing values (even when the selector is in the OFF position). If the temperature drops below 7° C, the thermostat still operates in HEATING mode with SETPOINT at 12° C and ventilation in AUTO, if the temperature of the water permits so. In case of Water Probe not present or continuous ventilation, the fan

AGLLI10/20NFJ 07/11_4528572_00

is always enabled. If the valve is present and the water probe is upstream or the water probe is absent, the pre-heating of the heat exchanger is still executed. The thermostat exits the Anti-freeze mode when the room temperature exceeds 9°C.

EXTERNAL CONTACT LOGIC

The thermostat also includes an external contact that allows to set it to OFF if it is closed (except if the thermostat is in anti-freeze mode or as a slave in the TTL network). This contact could be useful to manage inputs such as window contacts, faulty circulation pump, etc.

SLEEP FUNCTION

EMERGENCY FUNCTIONING

The two following failure cases are fore-

seen when the thermostat operates in the described manner.

NO WATER PROBE

- Ventilation is always active

- The season change is made on the basis of the difference between the setting made and the actual ambient temperature. If the ambient temperature exceeds by a value equal to the dead band, the Heating setpoint switches to the Cooling mode. If the ambient temperature drops by a value equal to the

VENTILATION CYCLES OF 2-PIPE SYSTEM WITHOUT AMBIENT PROBE

dead band below the Cooling setpoint, it switches to the Heating mode.

- The turning on/off of the resistance does not depend in this case on the temperature of the water but on the sheer demand for the thermostat operation

CASSETTE LOCAL NETWORK

The VMF-FCL thermostat has been designed to communicate with all thermo-

English

stats of the VMF family through a dedicated serial based on standard TTL logic and low throughput. This serial communication is essential for the exchange of information within small fan coil networks. This is in fact a network comprising no more than 6 thermostats with a maximum length of about 30 meters. 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-E4 is connected) that controls the operation of the Slaves connected to it, according to the settings made on its user interface.

OPERATING PRINCIPLE

The fan coil master, or rather the one

with the VMF-E4 user interface connected, cyclically transmits the following information subsequently setting them on the slave units.

- Regulation Setpoint

- Operating mode (OFF, AUTO, V1, V2, V3, AUX) (on the On/Off machines)

- Operating season

Therefore the slave fan coils can not

operate (except in particular cases) according to settings different from those dictated by the master.

AMBIENT PROBE: the ambient control probe is not needed on slave fan coils because these can use the control probe of the master. However, if you want to avoid having micro-climates, it can be installed on the slaves that will then adjust with the respective probe. In particular cases where the ambient probe on the master is faulty, the slave without probe will operate in emergency mode (similar to the master), while the slaves with ambient probe will continue to operate normally.

EXTERNAL CONTACT INPUT: this digital input is inhibited on all slave fan coils while it is enabled on the master only. If the master input is closed, all the slave fan coils of the zone are switched off.

PRESENCE SENSOR INPUT: the presence sensor digital input is only active on the master fan coil

ANTI-FREEZE FUNCTION: the antifreeze mode is the only case in which a slave that is in this status can operate according to settings are not provided by the master.

WATER PROBE: the water temperature probe can be installed or not on the various fan coils of the TTL network. The fan coils with probe will use this for foreseen minimum and maximum values control, while the ventilation will always be enabled on the fan coils without water probe.

AGLLI10/20NFJ 07/11_4528572_00

TTL NETWORK MANAGEMENT

No Master-Slave communication: the

slave fan coil cyclically await the zone settings from the master fan coil. If for some reason a slave fails to communicate with the master, it switches OFF (i.e. shutdown of all loads) after 10" from the last command successfully received.

No Master-User Interface communica-

tion: if at some point the master no

longer communicates with the user interface, it switches OFF after 10" from the last command received from it. The master will also send the OFF command to all the slaves. The user interface also gives the visual alarm AL 1

TTL NETWORK CONSTRAINTS

The constraint concerns the management of the adjustment dead band; this should be set on the master fan coil being that it is ignored on the slaves because both the setpoint and the operating season of these depend on the master.

TTL NETWORK EMERGENCY

FUNCTION

Master without Ambient Probe

The operating principle of the master

thermostat in the event that it functions without ambient probe (or fault of its

local probe) follows what described in the next paragraph.

Slave without Ambient Probe

The Slave thermostat cards enter into

emergency mode not only if the local probe is faulty but also if the master one is faulty too. According to what previously mentioned, if the slave probe is faulty and the master probe is working properly, the slaves continue to operate using that one of the master. If the slaves begin to work in emergency mode, they will be operated at the speed selected in the user interface and the valve Y1 is opened (this applies for both 2-pipe and 4-pipe system). Furthermore, the slaves in emergency mode do not follow the logic of the ON-OFF cycles based on the position of the temperature selector but are always in the ON phase, therefore with ventilation always running.

English

TTL NETWORK ANTI-FREEZE

PROTECTION

Master: As described in the ANTI-

FREEZE PROTECTION paragraph, the thermostat foresees as standard the control of the ambient temperature to prevent this fall to freezing values. If the master has to operate in this condition, it will impose all slaves to operate in AUTO mode with setpoint at 12° C, even though these are operating according to normal conditions.

Slave: Whereas if it is one of the slaves

operating according to the anti-freeze protection (despite the master is operating in normal mode), it will operate in AUTO mode with setpoint at 12° C. This is the only case in which the slave operates according to settings different to those dictated by the master.
