MAINTENANCE
ORDINARY MAINTENANCE
The ordinary maintenance, it can also be done by the user,
consists of a series of simple operations, thanks to which the
fan coil can operate at full efficiency.
Operations:
- External cleaning, weekly, to be done with a damp cloth
(soaked in water no hotter than 40 °C) and neutral soap;
avoid using any other type of detergent or solvent.
Do not splash water on interior or exterior surfaces of the fan
coil (it could cause short circuits).
- Filter cleaning, every two weeks or weekly
if installed in very dusty environments.
Clean the fi lter with a vacuum cleaner and possibly with
water and neutral detergent, do not use detergents or
solvents of any kind.
- Visual inspection of the state of the fan coil for every
maintenance operation; every fault must be communicated
to the After-Sales Service.
EXTRAORDINARY MAINTENANCE
Extraordinary maintenance can only be performed by
Aermec After-Sales Services or by people with the technical
and professional requisites qualifying them to undertake
installation, conversion, expansion and maintenance of
the systems and are able to check them in terms of safety
and functionality, in particular with regard to electrical
connections the following tests are required relative to:
- Measurement of the electrical system insulation resistance.
- Continuity test of the protection wires.
The extraordinary maintenance consists of a series of
complex operations that involve the dismantling of the fan
coil or its components thanks to which the condition of
maximum fan coil functioning efficiency is restored.
Operations:
- Internal cleaning, annually or after long periods of non
use; in environments where a high degree of air cleaning
is required, cleaning can be more frequent; consists of the
cleaning of the coil, ventilator fins, basin and all the parts in

DESCRIPTION OF COMPONENTSGENERAL INFORMATION
TLW1 (ACCESSORY) REMOTE CONTROL UNIT
Accessory essential for fan coil operation, alternative to the
PFW wired remote panel.
The TLW1 remote control unit is provided separately from the
fan coil. A single remote control unit can control several fan
coils.
The remote control unit makes it possible to set all the
operating parameters of the apparatus, these parameters are
shown on a liquid crystal display thus making programming
operations easier.
The remote control unit is fitted with a support allowing it to
be hung on the wall.
PFW WIRED REMOTE PANEL (ACCESSORY)
Accessory essential for fan coil operation, alternative to the
TLW1 remote control unit
The panel must be installed on the wall and connected to
the fan coil with the cable provided.
The panel cable is four meters long.
The PFW makes it possible to set the MAIN operating
parameters of the apparatus, these parameters are shown on
a liquid crystal display thus making programming operations
easier.
A PFW panel is designed to control just one fan coil.
FRONT PANEL
The air is sucked up by the slots. When raising the panel,
one has access to the air filter and to the other internal parts.
RECEIVER
Infra red signal receiver.
LIT INDICATORS (LED)
These indicators show the current operating status.
AIR FILTER
Air filters that can be regenerated are easy to extract for
cleaning.
THERMAL EXCHANGE BATTERY
This made of a copper tube with turbulented type aluminium
slats.
HORIZONTAL AIR DELIVERY DEFLECTOR
The unit is fitted with a motorised air delivery deflector and
vertical slats that can be directed manually in such a way as
to optimally orient the air flow.
AUXILIARY EMERGENCY SWITCH
The auxiliary emergency switch makes it possible to turn the
fan coil on or off in the absence of a wired remote panel or
remote control unit. To access it, raise the front panel
FAN UNIT
The fan unit consists of an extremely small, quiet tangential
type fan.
THREE-WAY WATER VALVE
The FCW fan unit comes with a three-way water valve
of the all or nothing type with electrothermal actuator
controlled by the fan coil card in accordance with the water
temperature and the temperature of the ambient air
.
The two available command models (PFW and TLW1)
provided as required as an obligatory accessory for the
functioning allow the turning on, the turning off and all the
fan coil control and programming operations.
The two command models cannot be used at the same time
on the same fan coil.
The control system checks all the functioning parameters and
carries out all the operations necessary to enable the required
environmental conditions to be maintained.
The control system also provides some automatic functions
to increase comfort and make the most frequently repeated
operations easier:
- Minimum temperature sensor, in order to avoid cold air
blasts in the winter mode allows ventilation only if the
water in the system is hot.
- Auto Restart mode, after a power outage the FCW unit
starts again automatically with the same settings that it
had at the time of the stop (with the exception of the
Timer).
- Type of operation.
- Programming of the timer for turning on or turning off.
Fan speed
- Activation of the motorised air delivery deflector.
- Three-way water valve control.
Turning the unit on and off.
SELECTION CRITERIA
FCW is fi tted with a standard internal three-way valve.
To function the FCW fan coil requires combination with the
remote control (TLW1 accessory) or alternatively the wired
remote panel (accessory PFW).
The tables in TAB 1 to 3 show the total chilling yield and
sensible to the maximum speed in accordance with the inlet
water temperature of its thermal change and air temperature
with dry or wet bulb, performance at medium and minimum
speeds are obtained by applying the relative correction
coefficients.
The diagrams of the tables in TAB. 4 to 6 show the thermal
capacity at top speed in accordance with the water flowrate
and the inlet water and inlet air temperature difference, for
lower speeds refer to the relative correction coefficients.
The diagram in TAB. 7 shows the coil pressure drop in
function of the flow rate at a medium temperature of 10°C,
for water circulating at different temperatures refer to the
relative correction coefficients.
The diagrams in TAB. 8 show the correction factors for fan
coils installed in systems with glycoled water.
Tables TAB. 9 and TAB. 10 show the level of sound power of
the fan coils at different speeds.
IMPORTANT INFORMATION
WARNING: The fan coil is connected to the power supply
and a water circuit. Operations performed by persons without
the required technical skills can lead to personal injury to the
operator or damage to the unit and surrounding objects.
MALFUNCTIONING
In the case of malfunctioning remove the power to the unit
then repower it and start the apparatus up again. If the
problem occurs again, call your areas After-Sales Service
promptly.
POWER THE FAN COIL ONLY WITH 230 VOLT, SINGLE
PHASE, 50 HZ
Use of other power supplies could cause permanent damage
to the fan coil.
USE THE (TLW1) REMOTE CONTROL UNIT OR THE WIRED
REMOTE PANEL (PFW) TO TURN THE FAN COIL ON AND
OFF
Do not turn the fan coil on or off using the auxiliary switch
unless it is an emergency.
DO NOT TUG THE ELECTRICAL CABLE
It is very dangerous to pull, tread on or crush the electrical
power cable or fix it with nails or drawing pins.
A damaged power cable can cause short circuits and
personal injury.
DO NOT PUT ANYTHING IN THE AIR OUTLETS
Do not put anything at all in the air outlet slots.
This could cause injury to people and damage to the fan.
DO NOT USE THE FAN COIL IMPROPERLY
Do not use the fan coil in animal husbandry applications
(e.g. incubation).
AIRING THE ROOM
Periodically air the room in which the fan coil has been
installed; this is particularly important if the room is
occupied by many people, or if gas appliances or sources of
odours are present.
CORRECTLY REGULATING THE TEMPERATURE
The room temperature should be regulated in order to
provide maximum comfort to the people in the room,
especially if they are elderly, children or ill, avoiding sudden
changes in temperature between the outside and inside above
7 °C in summer.
Careful choice of the room temperature will lead to energy
savings.
CORRECTLY ADJUSTING THE AIR JET
The area coming out of the fan coil must not strike people
directly; in fact, even if at a temperature that is higher than
the room temperature, it could cause a cold sensation and
resulting discomfort. Only adjust the vertical slats by hand.
For the horizontal air delivery deflector, use the LOUVRE
key of the remote control unit or SWING key on the wired
remote panel.
DURING OPERATIONS
Always leave the filter on the fan coil during operation
(otherwise dust in the air could soil the coil surface area).
WHAT IS NORMAL
During cooling function, water vapour may be present in the
air delivery.
In heating function it might be possible to hear a slight hiss
around the fan coil. Sometimes the fan coil might give off
unpleasant smells due to the accumulation of dirt in the air
of the environment (especially if the room is not ventilated
regularly, clean the filter more often).
