10 ACCESSORIES
pH - painted rear covering panel for horizontal
installation models FUI
The painted rear panel PH is supplied exclusively
for ceiling mounted éstro FUI fan coils with
apparent rear part in order to cover the technical
compartments (plumbing and electrical). It is
used to cover the technical compartments. The
fan coils with rear panel can work in heating mode only.
GE+C - Aluminium air intake grille with
subframe
The external air intake louver with anodised
aluminium fixed fins, complete with anodised
aluminium subframe is usually combined with
external air intake louvers and is designed for
wall mounting.
GEF+C - Aluminium air intake grille with
subframe and filter
The air intake louvers with anodised aluminium
fixed fins complete with washable acrylic fibre
filter and galvanised sheet subframe, is usually
combined with recess mounted fan coils.
GM+C - Anodised aluminium double-row
finned air outlet grille, complete with
subframe
Anodized aluminium air outlet grille with 2-row
swinging fins complete with galvanized sheet
steel subframe. It is usually combined with
recessed mounted fan coils.
S - Manual external air intake louver
The manual external air intake louver is designed
to allow frequent air renewals directly from the
fan coil. The quantity of renewal air is filtered and
heat treated by the fan coil and manually adjusted
by means of the flap located inside. This louver
can be used on all éstro BLDC models except
the floor mounted FU version. The installation of
a pair of covering feet (ZL for FLI fan coils and
ZA for FAI fan coils) is required, when the louver
is mounted on fan coil units with cabinet (FLI, FAI and FPI ceiling mounted).
SM - Motor-driven external air intake louver
The motor driven external air intake louver is
designed to allow frequent air renewals directly
from the fan coil. The quantity of filtered and heat
treated external air is proportionally controlled
from 0 to 100% by means of a servomotor
located inside.
The SM - SM-C kit is complete with servomotor
(protection rating IP54, 24 V supply voltage) and 230V - 24V transformer. The
automatic closure and opening of the louver can be obtained by means of
external auxiliary contacts (not supplied) as anti-freeze thermostats, timers,
etc. by connecting in parallel several servomotors to a single opening-closing
control. The louver should be coupled to one of the following control panels
(optional): CSB (installation on the unit) and CSD (wall recess mounted),
permitting to close and open the louver from 0 to 100%.
This louver can be used on all éstro BLDC models except the floor mounted
FUI version. The installation of a pair of covering feet (ZL for FLI fan coils
and ZA for FAI fan coils) is required, when the louver is mounted on fan coil
units with cabinet (FLI, FAI and FPI ceiling mounted).
CSD - Recess mounted control for opening and
closing the SM motor-driven regulating valve
Designed for wall recess mounting on the
opposite side of the fan coil control panel, it
controls the proportional opening and closing
of the motor-driven regulating louver SM (from
0 to 100%).
DF - Additional heat exchanger for 4-pipe
systems (hot water circuit)
Additional heat exchanger made with copper
piping and aluminium fins: it is suitable for
4-pipe systems and is connected to the heating
circuit.
The heat exchanger comes complete with air
vent valves on the system connection openings.
The kit comes compete with locking bracket to
avoid the manifold rotation during plumbing
connection opereations. The performances of the heat exchanger mounted
on the éstro BLDC fan coils are certified by Eurovent which guarantees the
reliability of the data shown on this manual.
vK - ON-OFF 3-way motor driven valve, with
hydraulic kit
The ON/OFF motor driven VK 3-way valve/4
connections kit connected to the control
panel for éstro fan coils, controls the room
temperature by stopping the water flow through
the heat exchanger. VK kit is available in various
configurations for all models of éstro fan coils
with standard (VK S) or additional DF (VK DF)
heat exchanger, as shown in the table below:
The kit includes:
brass 3-way valve / 4 connections with built-in by-pass, maximum operating
pressure 16 bar;
electrothermal actuator with the ON/OFF functions (total opening time 4
minutes), 230 V power supply;
Hydraulic kit for installing the valve on the heat exchanger, complete with 2
holders for balancing and regulating the fan coil unit.
