DESCRIPTION OF COMPONENTS
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
GENERAL INFORMATION
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.
